If it helps, this is the drive on my Flexispeed. Ignore the dust: I have been refitting the bathroom for ages and have not touched the lathe for months.

Thanks for checking these details, really useful

Thanks for this James.

I like the idea of that jockey wheel as that's obviously the tension adjuster and there's then no need to rig up a method of adjusting the countershaft position. The same principle can be used on the motor to countershaft belt.

Am I right in thinking you have assembled that jockey wheel from roller bearings mounted on a bolt or threaded stud?

The restoration is coming along reasonably well. I think I will be seeking some advice on a few final points but will raise them separately to avoid taking this post way off topic!

Yrs. The jockey wheel is about four cheap roller bearings on a long bolt, bolted onto a length of flat steel bar. The other end is screw to the block of wood that supports the counter shaft. It is all looks very crude, but it is effective. The belt firm the motor to the counter shaft is simply taut and has no tensioner. It never slips.

James.

Out of interest what did you use as a power source in that setup?
