Smokeywolf sent me a video of a nifty way of drilling cross holes while a part is on the lathe. I decided to see what I could work out.
I got a boring bar tool holder when I bought my lathe. I don't forsee ever using a 3/4" shank boring bar so the tool holder was never removed from the protective plastic wrap.
This was perfect. It would let me easily hold a drill at a right angle to the work piece. The carriage would let me easily set the holes at whatever location I wanted. Holes would be square to the part as long as I set the tool holder up square, a pretty easy task. Far easier than holding a drill plumb!
A length of O1 was turned to .750 for a snug fit. I then drilled a slightly undersized hole the length of the piece and reamed it to .3755 with a chucking reamer I had on hand.
I ordered a Jacobs chuck with a 3/8-24 thread on the back. That will be held on the end of a 3/8 inch rod that will slide thru the bushing I made today.
Once I get the chuck I will finish it and post some photos of the tool in action.
Thanks for a great idea Smokey! I appreciate it.
