Helical Couplings

Anybody here have any 1/2" helical couplings in their junk box they want to sell?
I figured I would ask here before I spend the big bucks for new ones. Please
contact me ____OFF LIST____ at scalion@.... Thanks.

ps. these are needed for servo motors, I got running with gecko G340 drives. If
anyone is considering stepper motors, I would strongly suggest using servos instead.
They are much smoother with no missed steps common with steppers. The drives
are cheap enough for the step and direction servo drives and the motors can be
had for a lot less than stepper motors of comparable size on ebay. I can get 350
inches per min on my machine now, and I haven't even tuned the drives yet. This
is much better than I could get with steppers, and I had good Compumotor 175V
S drives microstepped to 1000 ppr. Thanks Marriss for the great drive.

Bill
