"How To" wrap a rotor magnet...

[Tempted]

I would use a balloon. You can melt it off with a lighter without hurting the epoxy. Just pull as much off first, then burn the remaining a little at a time. Keep the rotor dunked in water as soon as you burn the balloon and it should be just fine.

Edit- I was just thinking, exactly how important is the exterior wrap? Just let the epoxy dry and sand it smooth.

I am not sure what you can use without affecting the epoxy itself, like WD40, or Pam, or some other kind of releasing agent. The proceedure is kind of interesting to watch from the outside perspective. Thank you for sharing this with us.

If I used the plastic type of heatshrink, such as the type used on lipos, I feel it would be easy to remove. I only had the rubber type and did not even think that the epoxy would stick to it...

Why not a later of way paper or something?

I may use some plastic wrap, as what's_nitro suggests.

Even better, use plastic sandwich wrap. It's very thin and also impermeable. Wax paper might still allow some epoxy to get through and stick it all together, plus it's much thicker than the plastic wrap.

I may try this out on something other than a magnet and see how it does.

I may just try to do it without using shrink. With a thin coating of epoxy and tightly wrapping the thread, the epoxy flowed thru nicely. I need a better method of holding the rotor while wrapping. Guess I will have to enlist the help of the bench vise...

You could also run the rotor off of a low speed motor or lathe once you get the epoxy done. It would prevent running and may even help with balancing.

I just use enough epoxy to coat the thread. My main issue is how to balance the rotor once the wrap is done...

[Tempted]

I'm stumped there. The only way I can think of has already been mentioned. Your prop balancer would be about the best choice and just sand the epoxy until it doesn't stop in the same place.

How is it coming along? Has the second coat dried yet?
