Engineers? A small drive shaft for belt-drive?

[WolfeMacleod]

These are my two coil winders.

I have an idea.

I would like to remove the tail-stock from one of them, and turn it around. Using some sort of belt-drive that's driven from the main spindles on the left, I think it would be possible to power the spindles on the tail stocks, same speed, same number of rotations, etc. This would make the machine a two-station winder. I've seen older winders built in a similar fashion before, with belt drives driven from the main spindle.
Doing this, I could extend the wire guides out to reach the tail-stock spindle.

Does there exist some sort of small driveshaft that could be secured to the table top, turned by the belt, and powering the second spindle? Belt passes downward, to the shaft, shaft turns, and passes a second belt to the tail-spindle.
Theoretically, it could be attached to the round black fastener at the rear of the top machine, instead of to the table.

I think the top pictured winder would be easier to work with. The tail-stock on the bottom winder has a funky lever mechanism that's used to move and lock it in place...

Reverse tailstock so they both turn the same direction...

What about this? Stack up your Bobbins (is that the name of the fiber piece before you wind it?) on a jig that extends between the drive spindle and tail stock. You would be limited by the distance between the two and the wire handling mechanism.

Helpful or not?

I've tried that before. Had a special winding face/spindle made that had rod extensions that locked into the tailstock. Bobbins slipped over the rods to hold them in place. Caused a lot of vibration, and scratched bobbins. One PITA about that method was... each bobbin need a beginning lead soldered to the coil wire, and secured to the coil. The placement of the beginning lead, so that it did not get in the way, was always a hassle, even with separator blocks...


A quick and dirty test using a pair of rubber bands and a drum stick show the belt-drive is viable.
