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 butt ferrule is dry fit. It mounted as conceived, but with caveats, which I’ll list after. Maybe you can guess them ahead.

So, laid out and shaped the seat as normal. (Btw, all hand work here. No lathe, no drill press…) Again, target diameter for seat is the valley of the fitting’s threads, but I knew I’d be a little wide at first.

(That bottom line was a mistake, but will go away.)

At this point I could have started refining the main seat diameter to get fitting threads started...
