Hi there my fellow geeks.
I have a little predicament. You see the pics, one show a metallic drum, another with kapton around it and one with a finished voice coil.
But I did not wind it....heee heee heeee.
I am just showing them so you guys can get the picture on what I am talking about.
I have been winding these and always had one hell of a time with it.
The wire is wound on a kapton bobbin. These voice coils are 300W RMS power handling 15" woofer. These things have been with me for like months, the only seller here sells them at USD200.00 per basket .
See the price tag of these suckers. There is no way I am going to spend 800 bucks to get 4 of these fixed.
So naturally I always wind them and every time I have to make a new drum to get the right diameter.
I am fixing these for the second time, at first I bought new voice coils on ebay and they ended up unwinded inside the air gap,. and the cone was rock solid..
This time I ain't buying but I had to buy the cone and the spiders.
I have kapton film and just recently got the wires.
Since repairing a woofer for the second time will damage the cone and the rest too much, i have to rebuild the whole thing.
And still I got everything half the price.
Now like I said, I am going to have a hard time with this, so I am asking you guys to do this for me.....Kidding
See the Pic with the voice coil (ready made) next to the drum.
I like to know how I can yank the voice coil after winding it without denting it.
After the winding is complete the kapton will be pretty tight and I cannot remove it without damaging it and to remove it I have to wind loosely, which is not a good thing for these woofers.
I cannot seem to figure out a way to wind it tightly and remove the voice coil easily. The drum is only 0.5mm larger than the magnet so I have to wind it tightly, and there will be two layers of coil, so loose winding cannot be used.
Before what I do is use paper between the kapton and drum, after finishing I can slide the paper out but this too works half the time and the drum should be smaller than the magnet diameter.
And making a bobbin is really hard thing here and expensive. I have to go to a machine shop to lath it.
So guys, tell me how I can accomplish this thing. How should the winding drum be made so I can take the coil with just two fingers.
