i am looking at comm lathes and have been told that the twister comm lathe is one of the better lathes for the money.
i can get one for $80.00 with diamond bit(guaranteed to be good).
any help out there?
I bought a used Twister for well over $100 from someone on HObbytalk and it didnt cut right. My motors didnt have any power if I cut the comm on it. I gave it to a professional RC driver named Chris Doseck who blueprinted it and reworked the entire unit-straightening the blocks and rebuilding the ways (sp?). It now cuts beautifully. I forgot what he charged me-but it was worth it!!
So to sum-up-Just because its a Twister doesnt mean a thing!!
I power my Twister Lathe w/ an old 4 cell pack but I use an old Tekin Motor Checker to control the power.
I set up the arm w/ nylon shims so it doesn't move around and put one drop of thin oil where the shaft rides. Spin up the arm slowly and using a black sharpie felt pen I cover the comm w/ ink so it's all black.
When cutting I make the smallest cut possible to remove ALL the black pen mark.
Dress the comm slots w/ a ground down old roll over antenna (Or a ball point pen works too, this removes the sharp edge)
