Yeah, I’ve tried several different method and tools not satisfied yet. Thinking about having a machine tool made.Whats the process of roughing that hole? stepped, drilled holes?
I have a machined taper bit I bought after doing the chairmaking class with Dunbar. It is solid metal not the hollow tapering bit. If you are interested I will try to dig out the contact information for the maker of the bit. The guy is in the New England area ----------or was, I really do not know if he is still around. I met him 20 years ago.Yeah, I’ve tried several different method and tools not satisfied yet. Thinking about having a machine tool made.
The problem I have had is finding one with 2 inches diameter at the top and 3/4 at the narrow end and over 6 inches long- preferably 8-10 inches long.I have a machined taper bit I bought after doing the chairmaking class with Dunbar.

Mine is quite a bit larger than that. If I could get that kind of price for my work I would retire from textile design and make tools full time.I bought a reamer from Elia Bizzarri in Hillsborough. It wasn't cheap but worked fine for making a few stools. I also got a tenon cutter from Lee Valley to prepare the legs.

The reamer I have would not work for you then, it is too small also. What you made is very similar to what Buchannan and the guy in Pittsboro use. It will do the job----just take lighter cuts or you may break it like I did with the one Buchannan had. At any rate, I think the taper was something like 1:8 taper.The problem I have had is finding one with 2 inches diameter at the top and 3/4 at the narrow end and over 6 inches long- preferably 8-10 inches long.
I bought a plumbers reamer that is less than 4 inches and it's too steep. Then a step drill that is also 4 inches long but the required 2 inch diameter.
Using both gets a little better but not really what i need.
I have the tapered machine reamer that Chris Schwarz recommends but it isn't nearly big enough for my project.
I think the one I made will work if I drill and bolt the tapered wood part through the blade so it doesn't flex so much.
I turn the tenons on the lathe for chair legs, using open end wrenches for sizing top and bottom of tenons and a template for length of taper. I turn the leg profile and make the tenon while it is on the lathe.I bought a reamer from Elia Bizzarri in Hillsborough. It wasn't cheap but worked fine for making a few stools.
