Helical or Helix Couplers

[Cobra]

I am installing ITB's and have seen somewhere on this forum somebody using Helical or Helix Couplers to connect their linkages.
Does anybody know of a supplier in Sydney or even Australia where I can get these?
Also the rod I am using is 7mm brass. What size bore would the coupler need to be?

Thanks in advance
Brett

C,

PM the guys who have posted ITB's, best chance you have.

Brett,

The couplings are often used for attaching encoders to rotary actuatuators and ballscrews commonly used on cnc machine tools. I used to have a toolbox full of them (20 years ago). Contact your local CNC spares supplier, there should be one in NSW.
