Bushing Sizes for Pipe Tampers

[tmhawk]

Hello all you fine Penturners,
In addition to Pens I make Pipe Tampers (smoking pipes). The ends need to be turned to 10 mm, 12 mm and 14 mm, for inserting the different cap ends. Can someone please tell me what pen bushings are those sizes? I have only 4 sets of bushings and none of them are that size. I checked the various vendors sites and instruction sheets and did not find any sizes.
Much thanks,
Tony

MAKE bushings. Corian, Delrin, Acrylic pen blanks can all be used for bushings.

Or you could probably ask Johnny to make you up a set if you can't find any you like.

I turn mine using a 7mm tube, closed end style, turn to whatever diamiter you want.
Then turn a brass plug for the open tube end and CA in place.
