On my Ciro the beeswax didn't work, it was too loose, so I put some boiling water in a mug and submerged the tenon for a couple of minutes. Then I pressed down on the stem with the tenon flat (perpendicular) on the tabletop firmly but carefully, causing it to bow out a bit and then inserted it into the mortise and repeated the process until it just fit tight enough. you don't want to overdo it, but that's an option. On my Meer, it came with a busted mortise and the replacement I bought didn't quite fit the tenon (mortise-hole too wide). I heated up a nail by giving it a couple of passes over a torch and inserted it into the hole in the tenon. I used bigger and bigger nails until I stretched the tenon out to fit the mortise. both were Ebay pipes.
