Wayne provided the following description: ================================================================= Here's some pictures of the boring head I've made recently (well I've been a little slow getting these posted so it was a while back). It's a 4" dia head that takes 1 1/4" boring bars (we often need to bore into long holes so a large bar is needed). I made nearly everything on this head from some kind of tough steel (probably 4140 heat treated if I was to guess).
