Many thanks!

A quick question:
Are Blogs 'crawled' by search engine's 'indexing bots'?

I have an inquiry in to the 'feedback' forum so... with any luck I'll have my blog 'up and running' in the near future -- Again, thank you!!!

HP I log in no problem I have not the problems you say in email means fixed then? I afraid you blocked so type your user to see every thing good but not log only cause not know your password which I left blank so don't worried somebody trying hacking your login just me want to see your missing access not personal Blog not making sense the link you say on troubles forum not point same as in alerts? I see blog can type comment on them ok I have tools you add on post 44 too

 

HP I log in no problem I have not the problems you say in email means fixed then?

Correct! -- Seems the problem cleared shortly after I posted my message to the feedback thread! --- Thus my email was 'old news' by the time you viewed it (a good thing!)

I afraid you blocked so type your user to see every thing good but not log only cause not know your password which I left blank

Actually the problem occurred prior to display of the homepage -- I can but guess It owed to security software attempting to 'screan out' connections from 'botnets'...

FWIW: While I genuinely appreciate your concern, maybe it isn't a good idea to enter other user's names even for benign purposes -- failed login attempts may well be 'logged' in which case you could be miss-identified as a malicious 'hacker'... Please don't get me wrong! I trust you implicitly! - I just don't want to see you in 'hot water' on technical grounds!

Blog not making sense the link you say on troubles forum not point same as in alerts? I see blog can type comment on them ok

Please see my response to your post as regards this matter on the feedback forum

I have tools you add on post 44 too

Good deal -- Again first installment should be 'up' sometime tomorrow

What means inverted storage?

Just that! --- Cap down

Why radiology literature they say mAs instead mc?

Jargon! -- They (i.e. so called "Techs" of 'that caste') are not programed for sentience - only compliance -- Appliance users of the world unite! Get it?

Bad enough just that but I say it miss mark anyhow cause charge transfer not straight forward for reckon dose?

Indeed! Correlation of (electrical) power input to (spectrally/energy specific) bremsstrahlung power output is dubious at best -- especially as sophisticated AEC techniques are hardly novel --- But to respond to your point: Historically current is more readily metered than power -- and, hence, by extension - charge vs work (respectively)...

As a point of interest [the above] is (somewhat) analogous to the old standard wherby radio transmiter power was assayed not by admeasurement of RF output power -- but by DC input power to the active component{s} of the final RF power amplification stage!? Happily, the regulators (at least) have reconsidered said practice...

HP thank about concerns for me about scalpels I already have so didn't buy now!

Good deal!

I say must have jeweler's touch manipulate fine wires like that for return line without break!

Just lots and lots of patience! -- A couple weeks previous T-Total abstinence doesn't hurt either

HP post about upgrade fb just lovely!

Very happy looking forward future installments

Many thanks!

Sounds good! -- That said - if you see an error, omission or cause for equivocation of any sort please speak up ASAP!

Not worth 5,000 dollars like you tell on email cause not autoclaveable platinum gebruder like that!

That's not the point! Should you suffer a loss corollary to my lack of perspicuity, then compensation of same is my responsibility! -- FWIW my guess at the $5k figure owed to your description of said instruments as 'the genuine article'...

if was stupid to spend all that for scalpels not your fault at all even cause you said no need real surgical instrument!

First off both you and I know you're not stupid - so that'll be quite enough of that! Secondly my (referenced) remark was not a 'disclaimer' merely a (helpful?) suggestion...

If cause you like say I'm smart you need say then too I responsible for if I do dumb choice like that!

I think lovely you think on me like kid sis or daughter figure so only don't forget to think like I'm grown up relative Ok?

I'm bound to say I find your confusion of my ownership of personal responsibility with condescension unfortunate! --- Hey Aleph -- I'm truly sorry that my offer of compensation seems somehow to have wounded your pride, but again, it was not, in any way, an offer of charity! -- Happily the entire matter was issue of misapprehension and overreaction on my part -- Very pleased to move on!

I know about you say power of perspective can't always live there though I try all time I not proud to be so morbid and neurotic

Actually... It's called being young, bright and having too much time on your hands! --- Trust me! You'll outgrow it - all too soon!

I say you could weave big top with spider silk wearing gloved hand

-- Or indeed walk across Baffin Island in mid January "wearing bare foot"?

you say in e about accidentally put imdb pw to attachment I say big deal cause you can change imdb pw!

That was my first move!

Now I say you most afraid hacker can tarnish sterling HP reputation by give poor film the good review? I wish that all I ever have worry about

Actually my concern centered more about my Gmail Addy -- there may be four or five people on this planet who don't know it yet

Well hey! Please don't draw the wrong conclusions from my occasionally 'petulant' tone! --- Know that I hold you in high esteem for your intellect, ambition, and, most of all, willingness to think insistence upon thinking for yourself! Additionally -- for anyone -- but especially for a person of your generation, you are delightful to converse with!

LOPT Repurpose Tutorial: Installment #1

Please note: I apologize for the 'full-size' presentation of the images! --- 'thumbnail' presentation is unreliable (at best) for images of the size and/or type attached
=========================================================
@Aleph(0)

I hope this finds you well!

Before beginning a few notes & comments:

Please be advised that the following procedure is both tedious and annoying in the extreme! -- Failure (i.e. inadvertent destruction of the winding) on one's initial attempt is not at all uncommon!
Please know that I am sincerely eager to assist and encourage you with this! --- I implore you not to allow pride or misapprehension of impatience on my part stand in the way of forthright reporting of your progress in the event of a setback! -- If I had a penny for every coil I've knackered... --- Moreover, recovery from seemingly hopeless situations is often attainable - so please toss nothing prior to consulting me!

Liabilities (or 'what to look out for' ):

--Far and away the most significant challenges attending this procedure owe to the 'gossamer' nature of #38 and #40 AWG conductors... It will behoove you to remain alert to the location of the EHT return whenever handling the assembly - while a severed or 'broken off' return lead is not necessarily 'fatal to the cause' - such will greatly complicate matters via requirement of 'teaseling out' the end of a #40 or even #42 (AWG) lead from the lacquered winding

-- While 'unraveling' the Aux winding apply counter-thrust to the shell -- not the tyre!

--While debriding residue from the 'medial gap' following removal of the Aux Shell - great care must be exercised to avoid damage to the medial layer{s} of the EHT winding

Please don't commence disassembly of your winding before all 'installments' are 'in' and we've had opportunity to discuss the matter!

To Begin:

For these purposes we will consider four (coaxial) features of the EHT winding assembly:

To Wit:

(Lateral to medial).
1) The EHT 'tyre' (containing/comprised of the EHT winding proper)
2) The Auxiliary shell (a paperboard or polymer 'collar' intervening the medial aspect of the EHT winding and the lateral aspect of Aux winding...
3) The Aux Winding.
4) The form sleeve (intervening the medial aspect of the Aux winding and the ferrite form).

Please note said features in the image below:

Intact EHT winding assembly.


Step 1 -- Locate the lug carrying the EHT return:

The EHT return generally emerges with one or more AUX leads from the lateral circumference of the AUX winding whence they are tied to a shell lug...

In this case said lug occupies the 2-o'clock postilion -- The image below shows said leads emerging from the Aux winding immediately below the CCW edge of the lug (as indicated by the ball-point pen) of special significance is the extreme peripheral position of the break-out point.

Image showing the bundle containing the EHT return.


Step 2 -- separate and identify the EHT return:

-Carefully unsolder all leads from the above identified lug.
-'Untwist' and otherwise separate the leads.
-With a resistance indicator check each lead for continuity to the EHT output contact --- the return will show a resistance of between 400Ω and 1000Ω All other leads should show infinite resistance (i.e. no continuity whatever).

In this case three leads were tied to the lug -- the continuity examination identified the 38 AWG lead as the EHT return (said lead identified by the pen in the attached image).

Image showing separated EHT return --- Note that the associated lug was broken out of the way.


Step 3 -- remove the form sleeve:

-Carefully 'dress' the return lead out of 'harm's way'.
-Twist, pry and/or break the form sleeve out from the center of the Aux winding.

Close examination of the image (below) will reveal the EHT return at approx 2:00 O'clock.

Image of EHT winding following removal of form sleeve.


Step 4) Remove the AUX winding:

-Cut leads attached to all remaining lugs.
-Using a small screwdriver or pick pry a few 'layers' of the Aux winding into the center such that they may be grasped with needle-nose forceps.

Image showing Aux winding as prepared for removal.


Grasp the the loosened layers and begin pulling out ('unraveling') the Aux winding -- Taking great care to avoid application of tension to the return lead as you progress toward the periphery.

Image showing Aux winding in an intermediate stage of removal.


The EHT return will generally be 'laminated' between the penultimate and ultimate Aux winding bunting layers -- very, very carefully break (not tear!) the paper away from the return lead.

In the image below you may observe the end of the EHT return (as per the pen) and its emergence from the bunting in the gap intervening the shell and the deflected bunting medial to the remaining lug at 4 O'clock

--Next installment continues with step 5--

 

@Aleph(0)

Hope things are going well for you! -- Just a note in case you get a chance to look in here:
I have completed the rebuild through attachment of the PP shell -- Two days curing are required prior to continuation...

So... I now have sufficient 'material' for another 'installment' which I will attempt to post sometime Thursday/early Friday in time for your return!

Very Best regards
HP

PS: Note; I'll attempt to keep the (most recent) installment on the last page -- then merge them into a single post once completed ....K?

 

LOPT Repurpose Tutorial: Installment #2

Please note: I apologize for the 'full-size' presentation of the images! --- 'thumbnail' presentation is unreliable (at best) for images of the size and/or type attached
====================================

Step 5) Remove the AUX Shell:

--Carefully break, crumble and/or fold the auxiliary shell into the 'medial gap' via symmetrical application of force to the distal labra of same at quadrature to the plane of the return
***Under no circumstances attempt to pry the shell from the interstices!!! Doing so will almost certainly damage the EHT winding beyond repair!!!***

-- having thus loosened the shell, carefully remove the fragments being ever mindful of the return...

Images of the EHT winding following removal of the auxiliary shell...



At this juncture the fruits of your labors should look something like this:



Note - Inasmuch as your LOPT is potted in silicone (as opposed to merely 'jacketed' as is the device featured in this tutorial) you should be able to arrive at this juncture sans exposure of the actual EHT windings -- Should a breach occur, prompt repair of same via application of electronics grade RTV is advisable...

Step 6) Prepare The Dummy Shell

Note: Owing to the 'brittleness' of polypropylene of the form under discussion use of a sharp instrument is recommended!
--Excise the the base of the pharmaceutical vial.
--Section the (resulting) cylinder longitudinal to its axis.
--Temporarily mount the dummy shell on the form -- Verify 'end play' ≥ 5mm (form pieces in firm apposition) If end-play < 5mm trim dummy shell to compliance but try to keep end play < 1cm

Image of prepared dummy shell:


Image of correctly 'trimmed' dummy shell on leg of LOPT ferrite form:


Step 7) Prepare Return Lug

--Form a #4 solder lug such that the 'tab' is at a right angle to the plane of the fastener surface.
--Drill a #66 (~.83mm) hole through the lug immediately above the bend.

Image of properly prepared lug -- Notice the small (#66) hole near the fastener angle: --- My apologies for the 'clutter' --'auto-focus' doesn't respond well to small objects in 'wide open spaces'
Step 8) Installation of the dummy shell

--Furl the dummy shell then insert it 'smooth edge first' into the medial gap from the non-return side such that the 'cut' faces opposite the output contact (mind the return!)
--Using a small stylus mark the dummy shell at the point directly lateral to the emergence of the return and 5mm back from the edge of the dummy shell.
-- Carefully remove the dummy shell
--Using a bit commensurate with a #4 bolt, drill a hole through the dummy shell at the point marked above... Note: Please resist all temptation to ream the bore to size! -- You'd only crack the PP...
--Liberally coat the dummy shell and gap surfaces with electronics grade RTV
--Insert the shell as described above taking care to align the cut opposite the output contact and the bolthole lateral to the emergence of the return lead.
--Place the EHT/Dummy Shell assembly on the ferrite form.
--Adjust the (linear) positions of the winding and the shell such that the winding is equidistant from the form pieces while the 'return end' of the shell extends as far as possible from the winding sans contact with the form piece.
--Remove the form from the assembly taking care not to alter the relative position of the shell/winding
--Using finger pressure expand the shell as much as possible -- smooth and 'touch-up' the silicone...


Step 9) Installation of the Lug and connection of the return

--Carefully insert the #4 bolt from inside the shell
--Secure the lug to the top of the shell as shown in the images below
-- Solder-tin the end of the return lead
-- insert ~ 1mm of the return lead into the #66 hole near the base of the lug then secure it with solder

It is imperative that you neither trim nor glue the return lead! Please loop the slack it as shown in the images keeping it free of the adhesive!

Images of the assembly; Dummy shell & Lug installed and return connected:


Verify that the DC resistance (lug to output connector) -- is that measured in step #2
If ok -- Take a deep breath and a tall drink --- the worst is behind you!!!

If not -- rather than 'taking it up with your radial arteries' -- Lets talk! - It may be an easy fix -- Rest assured that you're not alone -- Did you see my post (on the 'general' forum) in regards to broken tubes?


--- Next installment continues with step 10 ---


Anticipated FAQs

Q) Hey moron! the lug screw head will short the EHT return to the form -- and anyway who wants the winding rattling around on the form like that!
A) We're not done yet! --- Patience

Q) Ca One centimetre is insufficient spacing of lug and winding for 50kV operation - Dork!
A) That's why we're going to intervene lug and tyre with a thickness of PTFE in a subsequent step

Q) Why not trim the return lead to length or at least glue it to the shell? -- Afraid you break it? Candy A$$!
A) Prior to curing of the adhesive and robust securing of the lug, provision for 'immunity' to relative motion of the parts makes good sense

Q) What do spools of solder and capacitors have to do with rebuilding an LOPT - Silly bitch!
A) The extraneous items assist in achieving correct focus -- especially as regards small-ish objects

Q) Hey dizy doxie -- what's with the specific references in a tutorial style article? who the @!#& says my LOPT is potted in silicone!
A) The incentive and focus of this tutorial is assistance of the TS/OP -- I promise to generalize it at some future point

General question) Why are the questions so rudely worded?
A) Realism!

 

HP thank you much for offer the instructions I happy have something fun look forward to building and learning like great adventure Like you want I give the comments you said

--Carefully break, crumble and/or fold the auxiliary shell into the 'medial gap' via symmetrical application of force to the distal labra of same at quadrature to the plane of the return
***Under no circumstances attempt to pry the shell from the interstices!!! Doing so will almost certainly damage the EHT winding beyond repai

Very happy for precise explaining but I think funny how like cross between the geometry and anatomy Like q&a cause now know you will be telling how hv winding to be put around ferrite so not lose or shorting also about teflon spacer for lug makes sense cause 50kv not checked by a cm of air and few mm silicone rubber I think how you wrote rude questions is funny but you know I not talk like that to you! I happy these instructions but plz will you help me to walking through them when ready redo my fb? Here's delimiter

I know you saying joke but be serious I say I not commit a suicide not even for the good reasons cause nature take care of all that soon enough Plz don't worry I'm not ill accept for that I am mortal 1 minute 1,000,000 year no difference People say like prison of flesh and blood but worse than that cause prisons last better than human body You know how you say baby huey cartoon character for like no more Mr. nice guy thing? I say Huckleberry hound for father time cause when you watch him he hardly move but if your eye off him he gets ahead of you no matter how far away and fast you go! Happy to look toward next instructions don't worry pics show good most times if I keep trying

 

Hey @Aleph(0) --- Look for a reply to your post (above) this evening or early Sat AM --- Got a lot on right now...

OBTW -- I responded to your post on the 'GC' forum --- Thanks again for your concern but really - I'm alright!

Very best regards
HP

 

@Aleph(0)

pics show good most times if I keep trying

So... You're experiencing some degree of difficulty also...? I often can't get them to display at all - for hours at a time! --- My guess is that it's something to do with their size (>2Mb) --- Failing resolution of the issue I'll try to find an 'off site' repository for the images with links to same in my posts...

Very happy for precise explaining but I think funny how like cross between the geometry and anatomy

Indeed, and, I'm ashamed to say, perhaps (at certain junctures) a bit 'abusive' of both disciplines -- I'm pleased to learn my sacrifice of precision 'in the name of' perspicuity was not in vein!

cause now know you will be telling how hv winding to be put around ferrite so not lose or shorting

Yupper! Hence the length of CPVC and lots and lots of silicone adhesive

also about teflon spacer for lug makes sense cause 50kv not checked by a cm of air and few mm silicone rubber

One vital point though! If you, perchance, keep pet birds in the same building that you will be using the EHT apparatus -- do not incorporate PTFE of any sort in the apparatus! -- PTFE pyrolysis products are lethal to avians in concentrations significantly below the (acute) human toxicity threshold! -- Even the 'playing' of corona upon PTFE surfaces swiftly liberates avian-toxic concentrations! -- Although veterinary medicine/toxicology does not come under my purview I, nonetheless, fully comprehend the nature and specifics of the problem! -- If interested please PM or Email me for technical details... --- Rest assured many satisfactory substitutes for PTFE exist should you require same... --- Please make reference to this point in your response such that I know you saw it!

I happy these instructions but plz will you help me to walking through them when ready redo my fb?

That goes without saying!

I have edited the 'tutorial' posts such that the images are presented 'Full Size' (cumbersome though such presentation is)--- As per your input and my failed attempts to troubleshoot the problem via use of various browsers, operating systems and computers (with and without firewalls) -- I must conclude that the 'Thumbnail' mode is either 'broken' or incompatible with images of the size and/or type in use...

HP It's beautiful! I not see pics right before only small tab or go all to black now got fullscreen it's perfect!

@Aleph(0) As promised the following is a (refined) excerpt from my email message (of Aug 17 2015 -- 6:21:37 UTC-5):
=============
Following some experimentation - I have determined that acrylic-based 'hot melt adhesive' (e.g. Surebonder Acrylstik) provides a superior CPVC TO PP bond -- Said adhesive may be had at 'Home Centers' (e.g. Home Depot, Menards or their equivalent in your area)...

You may expect a reply to your post (and hopefully another 'installment') no later than Thursday evening/Friday morning...
Please take care!
