I made this boring bar for our shop in Az. It has an arm welded on to resist the torque when boring the inside of a piece. I had to make a piece to try it on so I picked one of the cherry pieces that was roughed out years ago. I found that the 1/2” carbide cutter with a very positive rake is really too aggressive in there. I'll be ordering some flat top carbide scraper discs.This was inspired by one I think LJ Zagreb has. The spring “feeler” is used to gage the wall thickness. When it straightens out, you are there!.The handle was made from 2 pieces of pistachio wood glued together and is finished with Kustom Grit and finally Shellawax.Cheers, Jim
