I'm going to turn and center bore a 1/2" diameter aluminum rod to 3/4" depth, inside diameter 3/8". The inside diameter needs to be a tight fit for a 3/8" insert. To finish, I need to drill a #22 radial side hole into what's now a tube. I've been having a hard time figuring out how to debur the inside of the side hole without spending a bunch on specialized tools; this may be a one-off part.
So I thought, why not turn a tight fit piece of aluminum rod to 3/8" and use it as a "backer" for the side hole operation. I'm thinking the drill won't see any daylight when it moves from the work piece to the backer, should make a nice, clean hole as if I'd drill into rod instead of tube.
Destined to fail, or has potential?
Thank you.
