I just couldn't let this one go! Had to see for myself if a piece could be attached to a bowl with almost no shank. I believe it can,although it's not something I would want to do very often and only to save a favorite pipe or a really nice chunk of briar.
I started with a bowl from an old Grabow Color Duke that I had chopped the bowl off of in order to make a tamper from the stem and shank. As you can see there's not much shank left.
I put the bowl in the vise on my drill press and used a 3/4" forstner bit to face it. This is the most important and the hardest to do because if you don't face it right the stem will be at an angle to the bowl. I got lucky and got it pretty close. I then used a 3/8" forstner bit to drill a hole 1/4" deep,believe I could have gone a little deeper.
For my "shank" i used a piece of cherry that I had started to make a tamper from and turned a tenon on it.
It is smaller than what would be needed if I was going to permanently attach it.I think I would use JB Weld to attach this close to the bowl,it's good for 600 degrees,other epoxies would I think soften from the heat--those I have anyway. I didn't drill the airway or mortise in this piece.
New shank in place! As I said a larger diameter piece would be needed so it could be sanded to blend in with the bowl and what little shank it has.
Maybe now I can save a few of those bowls that I chopped off to make tampers! :roll:
