Thanks Tom,

I know I said I wasn't going to go overboard with the details on this build but man I ca'nt help myself. The good thing is all my extra do dads came out to almost no extra weight, all just bits of foam, paper and epoxy. Rocket launcher anyone? I should have both skids done by tomorrow, once I have the panel lines on then I will finish the tail boom.  Wink

Cheers, Ray K.

Hello Tom,

You are correct I laminated 3  1/16" balsa disks cross grain then I drilled out lighting holes I then put this assembly on my Dremel and mill it smooth and cut the pulley groove with a diamond triangle file.

I do not have to worry about balance but I do have to make sure the pulley spins true and that there is no wobble.

Here are pictures of the finished pulley mounted onto the main rotor shaft, the pulley is secured to the shaft VIA a pin retainer. Just need to give the pulley a light dusting of paint.

Cheers, Ray K.

Lots of detailed parts on this build.  I'm guessing the pulley is a lamination of discs of appropriate sizes?  I like the lightening holes.  Do you have to worry about balance with this pulley?

Here is the main pulley roughed out, need to finish, 1 1/2" dia, tail rotor pulley will be 1/2" dia this will give me a 3 to 1 ratio between main pulley and tail rotor pulley.
