One of my next projects will be a shop stool. I plan to shape round legs and tenon them into an ash seat with tapered tenons. To taper the mortises, I was going to buy a tapered reamer from one of the Windsor chairmakers (not sure which one yet). Then I saw this on eBay: search item# 370786274725
There were several of these, and the descriptions said they are for machinists, plumbers, luthiers, etc. So can something like this be used for chairmaking? I didn't figure out the angle of the taper, but even if it's off a bit, the price is right. I don't have a lathe or I'd conisder making my own.
Any thoughts?
