I made a couple of mini BE chisels a while ago, out of some HSS flat bars. I was pretty pleased with them at the time, but being an obsessive type, it started to annoy me that the tapered ferrules were brass and looked out of place in the drawer beside the LNs. I could've solved the problem very simply, by putting them in another drawer, I suppose (:U).
When I made the brass ferrules, I cleaned out the insides in a pretty amateurish fashion, by drilling some stepped holes & blending them with a hand-held scraper. It worked ok (& this is the main reason I used brass), but feeling up for a challenge, I decided to try making some steel ferrules and turn out the inside taper with a bit more finesse. So I cobbled up a mini boring bar from a small tool-steel blank, and to my amazement, it worked really well. I did drill a stepped hole, to get the boring bit started, but it cleaned up the inside nicely, and of course I could also turn the outside neatly & safely, knowing the wall would stay parallel. So here's the result - a 3/32" and a 1/16": Attachment 399670 Attachment 399671
They won't work any better than the others, but they look more at home....
