John great looking tool and looks like it will do the job. What size of boring bar?
Dewey it makes doing a HF so nice. I had the kelton hollowers and with arthur in my elbow and hands it just beat me to death. I bought the Monster from Randy Privett and what a dream to use. I can do a couple of HF's sometimes three in a day where as before I barely could get one done and not without the help of about 3 advil.
I would love to make some of my tools but with a part time clock repair shop and a full time job if I made tools I would never get to turn.
