The subject came up in another thread and someone asked my about the jig I use to ream hosels.
Here you go. I snagged this idea from FGI member PhineasToad. This is known as the Toad clamp. I cut some small "V" grooves in the wood with a band saw. You stick the head hosel up through the hole in the press table and put the wooden clamp on it. You can run some carriage bolts through the wood with some wing nuts but I just used some C clamps since that is what I had. I don't lock the press table down and don't clamp the wood to the table. Letting it "float" helps center the bit.
