Hi Phantoma,
A good place to start looking for a fitter and turner is to ask at a local bearing shop, they usually know somebody retired who can do that sort of stuff in their shed
Thanks Norm, is it something a handy person could do themselves?
I still have an old drill press. I could screw it to a wooden bench and use some of my big G-clamps to secure the clutch housing in position.
I'd have to buy a 19mm hss drill bit but you can get a short shank one for $15. The key slot would be shallower afterwards but I could grind the keys down to fit.
