wookie1965 Posted November 22, 2017 Share Posted November 22, 2017 Can anyone suggest or make me a focuser knob for my Tal 100rs about 75 mm diameter. I was away at the weekend and Nick ( Cotterless45) had one on his vixen and for fine tuning on a single speed focuser they are brilliant. Link to comment Share on other sites More sharing options...
angryowl Posted November 22, 2017 Share Posted November 22, 2017 If you don't mind it being made of plastic then I'd be happy to design and 3D print you one. If you're looking for aluminium or something else then maybe some more experienced DIYers can chip in as I'm clueless when it comes to that I'm afraid.

Davey-T Posted November 22, 2017 Share Posted November 22, 2017 Maybe something like this would work ?

wookie1965 Posted November 22, 2017 Author Share Posted November 22, 2017 The hole in the middle of the shaft is 32. mm deep it has a 4 mm shaft and a 3.9 mm grub screw 25.4 mm from the thin end 20.5 mm from the wheel end if that makes any sense. perhaps this is more tricky than I first thought. Davey-T thats looks great just how I would fix it to the shaft. Link to comment Share on other sites More sharing options...
