I had that exact issue with the same type of coupling on a cnc plasma cutter. Of course it happened on a weekend and an urgent job. My solution was to use two simplex sprockets with a duplex chain connecting them. Worked well and I never replaced it again. I used 04-b2 chain 5.0mm pitch I...

Brilliant , did you have/get/buy plans for it thanks charles

Hope fully I have this right. If you choose 48mm as a centre distance and at a ratio of two to one would mean that the one gear would need a PCD of 64mm and one 32 mm. ( radius would be 32mm and 16mm to make up the centre distance of 48mm ) . Using module 1, the required no. of teeth is 32...

Is The reset switch for over temperature control. If it is leave it.

I used a clutch motor like that on an optimum lathe. It worked well but was a bit of a fiddle to fit. I liked the mechanism which worked the brake as it stopped the spindle quickly and can be disconnected if required. Sewing machines also now have a servo motor which are very small and variable...
