A wooden cue with a brass collar to which an aluminium extension has been addedA friend has a pool cue which converts to being a walking stick, by unscrewing the top and taking out the front part of the cue, then screwing that onto the front. The bottom of the walking stick part has a thread that needs protecting, and the cap is what hits the ground. The stick is too short for my friend, so I’m making a longer cap.

The thread on it is 3/8″ 12tpi. For those who don’t know threads, this is a weird size. It’s made for brass, which is brittle, so it’s a very coarse thread. I had to get expert help in sourcing s new tap to cut the thread.
