Wrapping the Coil on a Kayfun

[dherrington]

Hi. Even though this forum marks me as a veteran, I haven't gotten into it the way so many people have. RBAs for example, I am still learning.

I recently bought a kayfun and I am having the most trouble with what should be the most simple part of the process: wrapping the coil around the deck screws. It keeps slipping out. At the moment, I am using 28 gauge kanthal and wrapping it around a 7/64th drill bit. I place the bit in the center of the deck and then try to wrap the coil. That's where the problems begin.

I find the screws so tiny that I have trouble telling whether the wire is even under the screw. When I manage that, I start wrapping the wire and I can't get it all the way around. It could be because I have large hands and that makes it harder to work. But, for example, I find the drill bit in the way when I try to get it all the way around. So it constantly slips out and after awhile, the wire gets more and more bent.

Is there a simple trick to wrapping. I paid someone to mount my coil and I really enjoy the kayfun. But I don't think it is enough better spending 4 hours just trying to get the wire around a simple screw.

HELP!

Doug

Place the negative block facing away from you. When you wrap the coil, the tails should be coming off at opposite ends of the coil, both on the bottom. Place the coil still on the bit diagonally over the center of the air hole, bottom right to top left. Working with the post closest to you (bottom right) wrap the tail around the post to the left under the mounting screw, and secure it to the base with your finger tightly. Now tighten the screw down; tight enough to hold the tail securely. Now working on the other tail (top left), wrap it around under the screw to the right, and secure it the same way. You will notice by doing this, the screws are turning with the wrap of the tail as you tighten, instead of against it, pushing it out from under the screw.

Now remove your bit, pulse and squeeze the coil (if it is a micro coil), then tighten the screws down again securely. I have found that thermal cycling will loosen the screws, so pulsing it and re-tightening is a good idea either way. Hope this helps.

Next time you have your coil out, take a look at your screws. Some people have reported having screw heads with a rounded bottom making it difficult to trap the wire. If they are, you may have to either find replacement screws or try wrapping the wire all the way around each screw. I've also heard some people like to use some type of magnifying glass making it easier to see the little parts.

Great advice from above posts should help fix your problem - if not I use the below inexpensive led light head mounted magnifier - works great for me - especially for final inspection if nothing else.

Coil legs under. Wrap legs, one at a time around each screw. Wrap clockwise. A counter-clockwise wrap will be ejected when you tighten the screw. I can barely see, and my hands shake like a flag in a hurricane. I can do it no problem. I suspect you can too. The coil legs need not be wrapped all the way around. The kayfun is a nice ride, so keep at it. And, be mindful that a coil lasts a long time.

Real deal kayfun or a clone?

I use a tweezers for the whole operation. Fingers are too fat. Wire all the way around the screws and it works even with the crappy screws.

I have been Googling images of RBAs and while I have found lots of pictures and parts diagrams, I can't seem to find any that are labeled. How can one tell the positive screw from the negative one?

The positive screw is attached to the block that sits on the insulator. If you follow it out it is the center pin that hits the pos terminal on your mod. I hope my way of wording it makes sense. I've not seen a diagram that specifically labels pos and neg terminals.

Negative block is the smaller one - the one without the air inlet.

Someone knew where to look....lol

Ummm...Lol! How about is it the big rectangle or the little one?

Oops! I should have read to the end of the thread before posting! Thank you!

ETA: I feel kind of smart, that's what I guessed!

I'll go with the block on the left (door number 1, Bob....lol)

That's the big one, right?

That's right, no doubt at all......

I use these, they work like a charm

I learned something from this thread also! Mine has the rounded screws, so that explains why I have trouble!
