While making a saddle shaped mouthpiece for my latest smoking pipe, I managed to sand through to the airhole.
Because of almost finished ring on the mouthpiece and alredy glued tenon I preferred reparation instead of making it all a new.
I used my mini-lathe. The saddle shaped part was cut off.
On the rest of the mouthpiece was turned the thread with fine pitch.
I drilled and tapped a piece of the ebonite rod. Both pieces were screwed together and glued.
The process took me about 30 minutes and I saved the tenon and grinded ring.
The pipe is 153 mm long, diameter of the bowl is 45 mm. Chamber has 18 x 38 mm. Aluminum rings.
