The RV8 plans say to fabricate a bushing of 1/4" O.D., 3/32" I.D. to stick through the VA-146 center bearing on the horizontal stabilizer to protect it during drilling of the elevator horns. Use any old metal, they say.
OK, but I can't find any 1/4" O.D. tubing of any material that isn't already larger than 3/23" on the inside. If it were too small, I could drill it out. But the I.D.'s are too large already.
One option is a centering punch, available from Amazon. But that looks like multiple opportunities for error in such a fine-tolerance part.
So what about this bushing? What did you do?
Thanks in advance.
