I am just getting started in this game of chasing metal chips so I don't have a full chest of tooling. I needed a quick and simple boring bar holder recently, so I made this one up for my little HF 7x10 lathe.
Certainly not pretty enough to show off in the shop made tools section, but my machinist friend says "It's cute, any way."
I shaped the block. Then I chucked it up in the tool holder and drilled the hole to accept the boring bar. I drilled and tapped the holes for the set screws. I tried it out and found that I had to lock the set screws, so I made some longer ones and put locking nuts on them.
It works quite well for reaming the rim of a 7/8 nut to 1" wide, 0.080" deep.
Thought you might like a chuckle.
