Retrofitting hoops to bench chisels?
There's a few sorry looking chisels that I'm returning to usable form. The handles are adequate for users but the hoops are missing (the rings on the top) and the wood there mashed around a bit.
I don't want to remove the steel and so am wondering about whether there's a good way to true the step on the handle and dimension it for new hoops.
As a turner of course lathe mounting occurred to me but this will be complex to set up. Alternatively, mounted on a drill press table maybe the right size hole saw might work (but getting the right size will be a matter of chance).
Can folk recommend other ideas? How good a fit should the hoops be?
