I started restoring this ‘ciseaux bedane’ a while back and got sidetracked. Still some hand grinding to do on bottom, but it was almost there. These chisels are meant to be whacked hard, and I’ll need to put a handle on it with two ferrules, so I bumped it up as my test for using threaded brass plumbing fittings as ferrules. Strong.

The main caveat and lesson learned so far is, the fitting’s threads are rather large and simply do not cut a path through the wood. If I were to make a habit out of using fittings for ferrules, I’d get some matching dies and cut threads on the wood seats first.

In this case wood was clogging up threads, and that was also ripping threads off.

In the end, this screws on surprisingly tight, but the threads are not grabbing much. Epoxy will be necessary.

@wedge Any concerns with the epoxy holding up under the hammering?

Yes, since the threads didn’t cut as deep as I wanted. But there are definitely threads grabbing something, and some space in between, evidently. So epoxy definitely has something to grab. Plus the flange acts a bit like a cup hold epoxy in around the seat. It will be solid wood plastic and brass all the way through. That’s probably better than a brass ring by itself.

If not, I’ll make a new handle with a 3mil-wall steel ring ferrule . :)
