Exit Drill Guide
every Radio Control model I have built has needed
pushrod exits cut for the
Many R/C models have really ugly pushrod exits, but that bothers me. I
like to make the exits as small and neat as possible.
My normal method has been to mark the exit on
fuselage side and then drill a hole at each end. Then the holes
are connected by cutting between them with a razor knife leaving a
relatively neat hole. That has worked fine for the most part, but
still seemed unnecessarily tedious.
I decided to make a drill guide to accomplish
the same task. The first guide I made was cut at 15° which turned out
to be too steep for most of my aircraft. A second one was made at 10°
which works, but would still be better a degree or two shallower. It
might not be a bad idea to make guides from 5° to 15° in 2-1/2° increments.
It's been a while since I originally posted this article. Having used
these tools with several models I can say I am very glad I took the time to
make them. The results I achieve with them are much better than other
methods I used in the past.
