Please recall that the re-purposed application electrically 'floats' the EHT winding and operates at significantly higher EMFs and frequencies than anticipated by the original design -- hence the requirement of improved (80kV+) winding-to-core insulation and 'purging of parasites', as it were...

Shortbus -- I implore you! Please thoroughly study the Tutorial {Vol(A) and Vol(B)} -- While I realize it makes for rather 'dry' reading You will discover that it contains the answers to most of your questions

Thank you for looking at my contributions.

The first part of your quoted post, gets at something that I've seen as lacking in this, but was reluctant to bring up, to keep our conversations from spiraling out of control like they have in the past. And it may be hidden in this, now 70 page conversation. But this is my problem, I can't seem to recall either you or Aleph giving a for lack of a better word, a "mission statement". By that I mean, what is the end result, is the primary going to be powered by a higher than normally used voltage, to get a higher voltage out? Many other questions that I can't find words for.

The both of you have discussed this between yourselves I'm sure, off forum. That means you have a mission statement between yourselves, a known goal. People that aren't privy to that are just shooting in the dark. I know i am. I can't help much electrically because I don't have the needed knowledge, like the two of you. The mechanical part of it yes I maybe of help. And enjoy doing it, the biggest thing I miss since retiring is the problem solving.

I have read the tutorials several times. But all I can say again is it is meant for a college level class, not dummies like me. Having to sort through words not in every day language and figure out what you mean is mind numbing. I know that the both of you don't converse like this normally, you've shown it many times. Again my intention in saying this is not to criticize, but to make aware. Wouldn't it be better to during this phase of the project to make things easier? Then after getting a 'working process' sorted out, take it to your technical level of describing and writing. You have to admit that I'm one of the only members that has tried to help, and stuck through this, "long strange trip" since the start, so why make it harder than needed? With all respect and don't want this to escalate again.

 

Principally: Improvement of winding-to-core insulation via replacement of the unneeded, otherwise troublesome, 'coaxial features' (i.e. Aux shell, windings and sleeve) with insulating material (Spec. 'Acrylic', CPVC, PP, polyolefin, PUR/'Lycra' and electronics-grade RTV) -- Ease of reluctance gap adjustment and preclusion of 'parasitic issues' (arising from the Aux windings) represent 'fringe benefits', as it were..

Then why aren't you considering Kapton? From what I have found it is a better insulator than the ones you mention. And easily bought

 

Hi, Shortbus this is just brief response 2 ur latest posts Hopefully I'll have time 2 give full response to all ur new posts Monday!

I can't seem to recall either you or Aleph giving a for lack of a better word, a "mission statement".

Shortbus it's right here near top of Tutorial

====Introduction====

Scope of series:

Central topics:
This tutorial is one in a (prospective) series with focus upon low ripple, medium current/power PSU solutions for radiography and other modest photon energy (≤ 2 MeV) particle accelerator applications - and, to a lesser extent, exploration of certain 'current intensive' electrostatic phenomena (e.g. electret photography, electret formation, electrokinesis, establishment of electrostatically 'cordoned' (atmospheric) pressure gradients, high volume ion-flow systems, etc...
.
.
.
.
Scope of this tutorial
Provision of a detailed, 'step by step' procedure for modification of 'heavy duty'
AC LOPTs for 'serious' EHT application/research...

Said procedure having the following principal goals:
-- Improvement of insulation integrity via removal of auxiliary windings coaxial to the EHT winding.
-- Enhancement of versatility via electrical 'floating' of the EHT winding.
-- Appropriate adjustment of reluctance gaps.

By that I mean, what is the end result, is the primary going to be powered by a higher than normally used voltage, to get a higher voltage out? Many other questions that I can't find words for.

Shortbus transformers will be driven in forward transfer topology so that's huge improvement cuz sinusoidal output has mean output = √2/2*Ep (so like 70% of peak)! Also driver can drive transformer to hundreds of watts!

But all I can say again is it is meant for a college level class, not dummies like me.

Shortbus u and just everybody knows ur NOT a dummy! So self effacing humor can be funny but I say it can go too far too So anyhow here's HP's statement of target readership (Sry cuz it's basically buried on another thread I say it should be right on tutorial Intro!):

I wish the tutorial to be accessible to all sincere, interested, readers having demonstrated said 'qualities' via acquisition of the basal 'prerequisites' by any means whatever -- Said prerequisites being; secondary (aka 'high-school') level physics, fundamental math skills (i.e. 'through' vector algebra) and a 'working knowledge' of basic electronics -- A 'low bar' indeed! Howbeit, IMO, a workable starting point!

So it's basically skills anyone interested in electronics just as hobby will already totally have!

I know that the both of you don't converse like this normally, you've shown it many times.

Shortbus now I'm saying u have like _bee in your bonnet_ abt that! o/c it goes without saying tutorials and even just our _normal_ conversation aren't as lowbrow as when we're kidding around on thread! Which I say is vry good thing!

Wouldn't it be better to during this phase of the project to make things easier?

Shortus, I say dumbing down and condescending 2 readers isn't making things easier! It's just dumbing down and tacitly insulting readers! Shortbus a huge part of our motivation behind project (by which I mean whole series if we ever get it done) is alternative to 99.9% of what's out there on subject like Youtube and bad science sites that get the science totally wrong and don't even understand basic principles of what their doing! (So here's totally honest disclaimer: 4hv and some dedicated TC and IEC sites can be excellent resources too)!

Shortbus even when I was kid nothing tuned me out faster than ppl (like teachers) talking 2 me like I was idiot! So I totally agree with HP abt tone and rigor! But being honest I think she's making huge mistake by not insisting on better math skills from readers cuz just basic analysis (like freshman Calculus) isn't asking much and I say it would totally make better reader experience! So HP and I are basically deadlocked on that cuz she says some ppl won't consider that introductory level

Shortbus plz don't be offended but since you've expressed total disagreement with us abt formality and like that for long time, discussing it further is NOT collaboration cuz safe 2 say nobody on either side of argument is going to change his/her mind! So I say now it's closed subject for sake of amity and moving on in areas where we can help each other! So anyhow alpha testers gave vry favorable comments abt formal delivery and rigor and a lot of them even said they appreciated not being talked down to (which I can totally relate)! Shortbus I say that's important lesson cuz it's too easy to think on newbies to narrow subject as like _cognitive kindergartners_ everywhere! Which is just wrong! So shortbus this is not 2 say you shouldn't ask 4 clarification! I just mean let's drop discussions on appropriacy of style b4 it turns into a bicker! But we definitely want 2 help u or anyone that needs clarification! And o/c we'll know to rewrite passages that get too many requests for clarification!

Then why aren't you considering Kapton? From what I have found it is a better insulator than the ones you mention. And easily bought

Shortbus do u mean polyimide(sp?) film? If so ur o/c right about it being better electrical insulator with better thermal stability too! But CPVC tubing and and PP pharma vials are totally good enough for our application and they're already in easily used shape! Now maybe laminated polyimide sheets would be better choice than PTFE for strike insulator cuz HP is vry concerned abt avian toxicity of PTFE pyrolysis products so thanks cuz we'll definitely check it out!

 

I just started looking at this post and have not read them all so if what I am adding has already been covered I am sorry, but here it goes, my thoughts on using chemicals is that they could absorb into the insolation also which could cause problems, heating has been stated as working but damages the insolation so don't head the insolation, apply the heat to the core directly and do not heat the surrounding air. You would need to be careful not to heat it up too quickly as the thermal shock will cause it to crack. I hope this is helpful.

Slo_Moe serious thanks for interest! But since ur basically covering well trodden ground plz read discussion of disassembly problems so we can all start from same pov

 

Nope, I'm suggesting you try NMP ...

Cmartinez tnx! We'll definitely check it out!

 

Slo_Moe serious thanks for interest! But since ur basically covering well trodden ground plz read discussion of disassembly problems so we can all start from same pov

Thanks for the entry point, I did not go that far back in my reading of this topic.
Sorry to add clutter to this topic, just thought I had a different point of view on the subject that might help.

Sorry to add clutter to this topic, just thought I had a different point of view on the subject that might help.

@Slo_Moe I say u actually did help! Cuz by recapping issues and approaches u refreshed them for other readers too! So in case ur interested in our hv projects, latest version of our (as yet unfinished) LOPT Optimization Tutorial is in HP's blog starting HERE.

So plz, if you have any questions, comments or feedback or to report errors or omissions ur totally welcome to post them here (on this thread) anytime! TNX!

 

Looking good! -- See y'all next weekend!

Best regards

@Aleph(0) , @shortbus

FWIW It seems to me Shortbus' puller may be the solution to our problem?

Inasmuch as said implement both supports the core and applies balanced traction, successful separation should be achievable at significantly lower core temperatures (i.e. more viscous gap adhesive) than possible by 'hand' (the practical 'limiting factor' being down to the maximum 'survivable' cantilevered stresses at the 'angles' of the core)...

@shortbus, as I understand your drawings, the puller's tenure to the core is via compression? That being the case, perhaps application of (non-adhesive) anti-slip 'tape'/compound to the appropriate surfaces of the puller flange is indicated? - Thoughts?

With grateful regards
HP

PS -- @shortbus --- Should my remarks reveal any misunderstanding of your plans please tell me about it!

PS -- @shortbus --- Should my remarks reveal any misunderstanding of your plans please tell me about it!

In my experience making and using pullers like this, adding anything like sand paper, skateboard grip tape or anything I'm aware of is not helpful to making one work. Take for instance sand paper, to get grip on both puller and item to be separated, you would need to fold it in half or use two pieces. That means there would be two slippery paper/cloth side together, losing all of the advantages of the force applied to the item to be separated.

As to applying some unnamed compound to the surface, I know of nothing unless some form of a rosin that would work. Like I said above the actual compression has worked the best in my experience. the most critical thing is to get the clamping screws as close to the core as possible, so the force is concentrated on the core. As the screw position moves away from the core edge it will make the clamp bow in the center, and reduce the clamps effectiveness.

If any thing would be changed in my drawings it would be to make one of the bottom parts, ones without the "jack" screw holes, long enough to hold on too while turning the jack screws.

 

So I say now it's closed subject for sake of amity and moving on in areas where we can help each other!

No problem just say the word and I'm out of here!
But to make up "highfaultin' " words for things that aren't necessary and have common descriptions used in normal conversation is what I'm talking about. Take for example calling the metal frame surrounding the original LOPT. Calling it a "ligature" instead of surround frame and tie strap. Who on this forum or any online forum talks like that? Maybe there is an Elizabethan electronics forum somewhere I don't know about.

Do you really expect me to believe you go to Starbucks and say to the counter man , "my good man, I request a steeped concoction of the roasted seed of the genus Coffea". Give me a break.

Shortbus u and just everybody knows ur NOT a dummy!

Your friend TCM would dispute this.

So anyhow alpha testers gave vry favorable comments abt formal delivery and rigor and a lot of them even said they appreciated not being talked down to (which I can totally relate

And just how well did that 'alpha' project work out? A bunch of paid, spoiled school kids that have no real world experience in almost anything, other than going to school. That couldn't even follow, "formal delivery". Maybe they can come up with a 'better' way to get you to the end goal.

So it's basically skills anyone interested in electronics just as hobby will already totally have!

This and the post by HP that you quoted automatically makes my participation , according to the both of you, a non participant. Because I have none of the requisite skills outlined. So like I said in my first response in this post, say the word and I'm out of here, with no grudges held or anything but good wishes toward the completion of the project.

 

@HP, just in case I don't continue with this thread here are some part numbers from McMaster-Carr

1/4-20 clip nut - 94850A129 https://www.mcmaster.com/#clip-nuts/=1ajjofg

1/4-20 eye screw, for the 'jack screw' - https://www.mcmaster.com/#eyebolts/=1ajjqlk couldn't pick a number since it will vary by application. You want the ones they call, "routing eye bolts.

Both of them are also available at Ace hardware or many other full service hardware stores.

 

No problem just say the word and I'm out of here!

Shortbus Ur taking things too personally! Cuz we definitely don't want u out of here!

But to make up "highfaultin' " words for things that aren't necessary and have common descriptions used in normal conversation is what I'm talking about.

Shortbus so to you some of our descriptions are _highfaultin_ and to us some of yours are imprecise and _lowbrow_ all for sake of accessibility 2 some ppl with poor English communication skill (which definitely is NOT you!) But it doesn't work that way cuz imprecision is always bad teaching, condescension is always insulting to intellect of reader and anyhow another prerequisite @Hypatia's Protege forgot 2 mention (or maybe thought went without saying) is conversance with English language! So ESL students are totally welcome and we'll help them out all we can but this isn't multilingual course or special English! So here's important point so plz read vry closely: NOBODY is calling u dumb! We're just saying ur underestimating language skill of target readership!

So Shortbus it's time 2 just agree 2 disagree abt writing style and move on! But I can totally say this cuz HP and I talked abt it a long time ago: When we include instructions for your tools and techniques (like puller and D'arsonval meter mounting and anything else suggested by u) we're totally happy to just cut and paste your prepared text! So your contributions can be 100% in your own words with attribution!

Calling it a "ligature" instead of surround frame and tie strap.

Shortbus they're two totally separate parts! So the ligature is what ur calling _tie strap_ (which holds frame together but isn't really part of frame)! So anyhow IMO _ligature_ is better word choice 4 part cuz it describes its function w/o defining its form! Cuz LOPT frame ligatures are sometimes just long cylindrical bolt{s} or just cable{s}! So u can see examples of cylindrical ligatures and frames that don't totally surround core by reading Tutorial! Plz!

Maybe there is an Elizabethan electronics forum somewhere I don't know about.

Shortbus being totally serious those terms aren't obsolete at all! So maybe they're more common in scientific than technical circles but they're definitely in common usage! So I'm wondering if maybe it's like HP thinks. That it's just dialectical difference except based on field of endeavor instead of locale?

Do you really expect me to believe you go to Starbucks and say to the counter man , "my good man, I request a steeped concoction of the roasted seed of the genus Coffea". Give me a break.

Shortbus Since I wouldn't be caught dead at Starbucks I can't honestly know what I'd say! But I know I wouldn't say _Yo! Hows about a swig of Joe!_ Now being totally serious ru putting appropriate tone of instructional text and interpersonal conversation on par with placing order at coffee bar?

Your friend TCM would dispute this.

Shortbus Plz! This isn't place for sniping and brawling! If u have problem with other members then that's totally between u and them!

And just how well did that 'alpha' project work out?

Shortbus u know it basically failed for like 1/3 of participants which HP and I call total failure! Good news is that critical problem was totally limited to breaking core cuz most ppl who got past that stage finished w/o problems! So taking core apart is big problem but I agree with HP that u maybe found solution!

A bunch of paid, spoiled school kids that have no real world experience in almost anything, other than going to school.

Shortbus being fair they weren't paid at all! All they got was money for materials and parts! Also I say it's unfair 2 call them spoiled cuz of one loudmouth! Anyhow I totally relate to his frustration cuz on my first try I broke cores too! So I agree that's no excuse for him baiting @Jazz2C into fight or for @Jazz2C to be so easily manipulated But none of us claim 2b perfect!

That couldn't even follow, "formal delivery". Maybe they can come up with a 'better' way to get you to the end goal.

Shortbus formality was broadly appreciated and more than that, it was saving grace for ppl who had problems viewing pics Which isn't 2 say pics aren't absolutely necessary but I say it says something vry good abt formal descriptions!

Shortbus u talk like u have a _hate_ on for alpha team? So if that's based on what we've said on here I'm sry abt my part in making wrong impression! Cuz it was like three crybabies and one _pottymouth pugilist_ trying 2 provoke JC! Which I say are pretty good averages considering level of frustration over broken cores

This and the post by HP that you quoted automatically makes my participation , according to the both of you, a non participant. Because I have none of the requisite skills outlined. So like I said in my first response in this post, say the word and I'm out of here, with no grudges held or anything but good wishes toward the completion of the project.

Shortbus all I can say is u must have misunderstood post! Cuz I can tell from ur posts on this and other threads that you have math, science and technical skill totally exceeding prerequisites! So did u miss sentence where HP said that skills can be obtained by _any means whatever_? So _high school_ math and science doesn't mean 2 say you had to learn skills in HS! Just that skills are at or above same level Now Shortbus even if you still think u lack those skills you have totally shown you have more than it takes for this! Cuz I totally agree with HP that school is for credentials but real learning happens in real world!

So this is to everybody including ppl who really don't meet prerequisites! You are all welcome and we'll be totally happy 2 help ppl having trouble regardless of background! Prerequisite statement is really just generalized background profile of ppl we think are most likely 2b interested! So if Tutorials look interesting ur totally welcome!

So like I said in my first response in this post, say the word and I'm out of here, with no grudges held or anything but good wishes toward the completion of the project.

Shortbus HP and I are vry pleased and grateful abt your willingness 2 help and for example your puller and other ideas (like injecting anti-adhesive agents under core sleeve, using polyimide insulation instead of PTFE and prolly other suggestions I haven't had chance 2 evaluate yet) So everyone can see u found solutions where we were just stuck! Now I wouldn't admit that about myself or dare speak for HP that way if we had superiority complexes (like u seem 2 think we do?) so plz stick around!

So only problem is topic keeps returning to debate of appropriate writing style which wastes all our time (including yours) and isn't even the problem! So let's just live and let live and remember that your contributions can be totally in your words!

So thanks for post 1386, 1387 and all other content on topic of dismantling core! Which I'll get to soon as real life schedule allows! Also HP will be back 2 participation on here soon too!

Edited by Aleph(0) to correct post references

 

Shortbus being fair they weren't paid at all!

What you call not paid is absurd! $1000 with the LOPT provided is what I would call being paid. For even buying everything needed for the dismantaling at retail from a 'box' store I would think this could be done for around $100. Even less if you got some of it from Ebay. So to you the other $900 wasn't a payment? A gift? It seems to me that the two of you are forgetting that even by an alpha test those people were getting something they either want or need to further their education. Call it payment or subsidy, it still is what it is.

Shortbus u talk like u have a _hate_ on for alpha team

Not at all. I can honestly say at this point in my life, soon to be 70, I harbor no hate for anyone. Not some one I have had personal interaction with or some unknown students. Where I have a problem is that you two released this project "into the wild"(alpha) without even a prototype of how to do it. You said yourself that you broke a few, and you knew that you were after. So how to justify $3100 plus what ever the LOPT's cost as an alpha? Your money and your call, but seems like a waste to me. Just my opinion.

Shortbus so to you some of our descriptions are _highfaultin_ and to us some of yours are imprecise and _lowbrow_ all for sake of accessibility 2 some ppl with poor English communication skill (which definitely is NOT you!)

So you are saying that nonenglish speakers will be able to understand all of the obscure wording that HP uses? While many here question my mentality, The words I use are the ones I have used all of my life, low brow or not.

So only problem is topic keeps returning to debate of appropriate writing style which wastes all our time (including yours) and isn't even the problem!

Did you miss the part in my earlier post where I said something to the effect of, "cut the high brow speak until a solution is reached"? I'm not asking you to change the tone of the final tutorial, but just during this 'prototyping' phase. Then you can use what ever language you determine is necessary, put it in old Coptic, for all I care. The problem I'm having is you need/want to get a solution that works and are willing to "pay" others but flat out refuse to go along with a simple request from me. Guess that last sentence boils it down from my point of view. Self serving? Maybe, probably, but it seems like not too much to ask.

 

What you call not paid is absurd! $1000 with the LOPT provided is what I would call being paid. For even buying everything needed for the dismantaling

Shortbus dismantling is only part of it! If u read on Tutorial u can see they also need parts for rebuilding plus chemicals and special tools too! Also they need allowances for newbie mistakes!

even by an alpha test those people were getting something they either want or need to further their education.

Shortbus I hope so! Cuz one thing's for sure we got a lot more from them by their taking time 2 show us where strengths and weaknesses are! So for example they already prevented us from causing like a 3'rd of _gamma_ readers 2 ruin their cores!

Not at all. I can honestly say at this point in my life, soon to be 70, I harbor no hate for anyone.

Shortbus I'm happy 4u that you're not feeling _hate_ cuz that hurts ppl who feel it way more than object of emotion But based on your remarks on last post and further down on this one I say you're sounding vry angry toward them and there's just no need for that!

Where I have a problem is that you two released this project "into the wild"(alpha) without even a prototype of how to do it.

Shortbus we had exact plan for doing it that we thought we'd perfected (which is what's in present Tutorial). What we didn't know was that all we did was accidentally acquire skill at disassembly from like _collateral practice_ from trying different vry similar approaches so what we thought were _improvements_ didn't really matter So it's just for reasons like that we conducted alpha program so now we know exactly what needs 2b reworked and what doesn't! Shortbus I'd totally agree with your point abt wasting time and materials if it was beta or gamma phase! But it was just alpha phase! So finding huge problems that can vary between ppl is exactly what alpha testing is for

So how to justify $3100 plus what ever the LOPT's cost as an alpha?

Shortbus it was only $1k per tester including price of ≈$40 FB! So number of enrolled testers maxed out at 38 so cost of entire project stayed less than $50k including overhead! So I say we got a lot of good info on the cheap! Anyhow that's totally the point of alpha testing! Ur talking like alpha test was _go live_! Alpha testing is super painless way of finding out what needs work at outset so we don't waste time effing with stuff that's already good or letting big problem (like breaking cores) out for public consumption! That way when we go live with project, readers can be confident that it's thoroughly tested! So after we get all this sorted out we'll do beta testing 2 find more insidious and less frequent problems, then gamma phase which is basically feedback from _go live_

So you are saying that nonenglish speakers will be able to understand all of the obscure wording that HP uses?

Shortbus non-English language readers won't understand any English at all Now ESLers can count on us for assistance but we can't bring tone of Tutorial down to _special English_ just 2 accommodate small demographic! Tutorials are intended for English language readers! So that can include some ELSers who have almost mastered English and we'll try 2 help earnest ppl having trouble with language barrier all we practically can! But tutorials are written by English language readers for English language readers as intended readership so that's where best reader experience will be! So that's not _discrimination_ it's just part of scope of series!

the words I use are the ones I have used all of my life, low brow or not.

Shortbus we're not asking u 2 change your linguistic style! Like I said in other post, any contributions u let us use can be totally in your own words! Now I'm sry if u found _low brow_ insulting but calling correct usage of words in common use _highfalutin_ and _obscure_ isn't nice either! So I wasn't trying 2 insult u! Just showing u that attacking somebody's style or dialect is rude!

"cut the high brow speak until a solution is reached"?

Shortbus I'm telling u from knowing her all my life that @Hypatia's Protege isn't being artificial at all and according 2u you're also _using words u used all your life_ so since we're all native English language speakers I say no one has 2 change tone or dialect 2b understood by the others!

The problem I'm having is you need/want to get a solution that works and are willing to "pay" others but flat out refuse to go along with a simple request from me.

Shortbus your _simple request_ is totally RUDE! Cuz ur basically saying u don't approve of HP's manner of expression so she should tailor it 2 suit your sensibilities! Maybe u should change your manner of expression 2 HP's for her convenience? Shortbus now I'm saying difference between u and us is we don't ask u 2 talk like anyone but yourself! Also plz remember that u offered 2 help already knowing how we write! Shortbus as valuable as your ideas really are 2 us, I say asking us 2 be inauthentic is too high a price!

Shortbus I have politely asked u 2 drop debate of writing style TWICE! But u refuse 2 let it go! So we don't harass u abt your style or tell u how 2 talk on here (and on your forthcoming contributions 2 Tutorial either) so all we're asking is same courtesy in return!

Shortbus So what's it going 2 be? Can u return 2 focusing on problem at hand which is safe disassembly of FBs?
Or are u just going on with litany of bellyaching abt how stupid u think we are for the way we write and how we conduct testing and proofing programs and your low esteem of all involved in them?

Shortbus I really believed u when u said u seriously wanted 2 help! So even now I totally think it's possible things accidentally slipped into a tit-for-tat cuz u misinterpret formality as affectation and we have different ideas abt what things (like alpha program) are worth monetarily? But that can all be put behind us just by focusing your next post on just problem at hand w/o digressions and nitpicking other areas that aren't even a problem! Also like I said b4 if there's anything that's not clear plz just ask 4 clarification but plz be specific! Shortbus now I'm saying on topic post would be 2x nice for me too cuz then I can make on topic reply instead of multipage response to irrelevancies we've already talked into ground!

So plz! Let's have fresh start!

 

So plz! Let's have fresh start!

@shortbus The suggestions about writing style, test programs, costs and such have been noted and addressed by the TS. Further contributions should be confined to the technical/mechanical aspects of the project.

 

Alright I get it. My help is wanted as long as my talk doesn't hurt any one's feelings. I will continue to follow this but will only comment where I can be of help. Or not

 

Alright I get it. My help is wanted as long as my talk doesn't hurt any one's feelings

Shortbus I say your help is totally wanted as long as u observe common courtesy! U said u didn't want to reignite bickers but u just kept harping on how we write and basically live our lives and issues u know we consider settled! Also I think u owe members of Alpha team (some of who read here) an apology for basically calling them spoiled losers just cuz in your opinion HP is being too generous with expense allowance! So whether or not u post apology 2 them is between u and your conscience and I won't mention it again unless u do.

I will continue to follow this but will only comment where I can be of help. Or not

Shortbus u know we'd be total hypocrites to insist ppl stay right on topic! So we just ask ppl 2b civil and stay away from contentious and talked out subjects! So plz think on your posts on here from back when we all got along! I say there's absolutely no reason why we can't return 2 that! Tnx!

 

I'd just like to say something before we continue:

*sigh*

... there, I feel better already... could we please move on... and don't look back?

 

@shortbus If we're still on speaking terms (which I really hope we are) could u plz help me out with your drawing?

So for convenience I also attached pics showing names I'm using for parts of core pieces (which I cite in questions with bold text)

◊Horizontal bolt at bottom of your pic looks like it's going through bore in core but the core isn't drilled or like that cuz it's just two identical solid pieces. So I think ur saying bolt should pass near core on inside of angle of semi-leg and rail is that correct??

ETA @shortbus Just thinking on it I say ur saying to run flange securing bolts near as possible 2 OUTSIDE ends of core legs? So that's no problem even on tire leg cuz aux can be notched out if need be but flanges need 2 extended 1/2 tire diameter past upper leg for puller bolts 2 clear tire.

ETA2 So after carefully studying on other drawings I think I FINALLY get it! Puller bolts are between bottom of tire and lower leg? So only question I have now is how to prevent rocking/tipping torques when joints yield unevenly? Cuz if we can do that it's totally perfect!

◊So is it implied that there's another bolt across from it (so like above it in your pic) in same place relative to other core piece on other side of hv tire?

◊Also here's another question: Can u think of any practical way to have a puller on upper core leg and one on lower core leg that are synchronized so they pull core apart at EXACT same rate (to prevent like rocking and tipping torques)? Cuz that would be awesome cuz with just linear tension on legs core could prolly be separated by just heating entire FB 2 tire safe temp with no solvents or carving at all!

So based off her post I think @Hypatia's Protege understands it better than me but she's way too busy 4 me to ask her abt it now and anyhow since it's your design nobody knows better than u! Also plz be patient cuz like I said I'm not vry mechanically inclined So tnx in advance!
