Where to find (extension-) joints for self-build cues?

[breytex]

Hello there!
Started to build some cues on my own, but cant find any shop selling good joints.

Found some low-budget joints for 3/4-cues on ebay, but
havent found any Extension-Joints yet.

Someone has a suggestion?

Thanks in advance!

They are available but be warned a lot of cuemakers use their own joints and one joint does'nt fit all extensions/cues. It can be a minefield.

Even airlocks I've got two sizes
I had to take a lathe to the outside of one to make it fit on my Welshpool.
