I'm making a (sort-of) copy of the SB Lathe Tool Grinding Block. The original had a square, broached hole for each size of toolbit. I can't go there, not at $100 for one square broach!
So, I turned down a cylinder, with a larger end. The less said about the quality of the turning, the better. I did this a while back, when I knew even less than I do, now. I'll mill a slot for the toolbit.
Now I'm faced with the problem of how to secure it, while I mill the channel. The "over-the-top" clamp that came with the v-blocks would get in the way of the spindle. I saw a picture where someone had machined a "C' block to go in the slots in the side of the block, and tapped it for hold down bolts.
Worked great! Now I can clamp it in the vise, indicate it properly, and mill my channel.
