There seems to be a myriad of info and designs for what I need so I thought I might ask to avoid learning on my own what does not work. I want a boring bar and the holder for a small lathe. I have an 11 inch logan with a lantern post tool holder. What type of holder and boring bar would work good? I currently use HSS cutters as they are sharp and makes life easier on the lathe. I see lots of boring bars with carbide inserts but I am not sure if I have enough rigidness for that. I need to bore a pulley from .625 to .670. Thanks !
