This week and last week I spent time working on updating by boring bars. I had some boring to do on large diameter tubing to do. I have had these bars for a long time but I had not set all of them up to use on my current lathe. I used many of them at work before I retired. The only factory bar I have is the one in the photo in the lathe. It's a beast. The others in the other photo are home made, well, some at work too.
The two on the left in the last photo I just made last week. They have a 90 deg end and a 45 deg end. I like the double end bars as you can guess from the photos.
