I have got them on the list of things to do but I think it'll be a month or 2 before I can afford them need to buy the bits for my mates arcade table first so will probably use these couplings till after xmas and look at upgrading then. I can do the motor's at same time and only have to buy the hubs once.

I think I got the nema's aligned straight enough for oldham couplings.

I'm guessing I have to use 2 hubs and a torque disc?
