[NSRCA-discussion] Aileron lead holes

[Keith Black]

I'm not sure if you have a jig of some sort keeping the brass tub straight, if not, then you should do so for the next suggestion. 

Take that same brass tubing and hit it with a propane torch to heat it up. It will then slide through the foam with great ease. You'll have to remove it and reheat about three or four times. Actually I believe I've used a 3/8th inch brass tube when using this method, not 1/2". I don't know if the extra 1/8th inch will cause it to burn through the top or bottom of the wing.

  I'm looking for alternate ways to bore the aileron lead hole in a foam wing core. In the past, I've done it with 1/2" sharpened brass tubing. Anybody got a better way?

  Thanks,
