Where did you get the gears for your mount, and what motor did you use?
Plans for my single arm barn door are coming together, slowly. 32 TPI rod seems to be hard to get at a reasonable price, however I can get 1/4" BSW rod (20TPI) at Bunnings, along with appropriate nuts. Will this work? I realise the radius will need to be bigger as will the arm. I could use 3/16 rod at 24 TPI, but Bunnings don't seem to have 3/16 nuts available without screws, perhaps the 3/16 rod would be too thin. Thoughts?
