I'll have to wait until I get the motor for the through mounting hole dimensions but was thinking of something along these lines.....

Mark, where did you get your belleville washers from? Was going to stick a couple in between my single row AC bearings?

eeeerrrr, dunno?? pretty sure i got them on ebay.... i just did a search and they are all coming up USA which is a bit of a bind, iv got some left (8.2mm inside 18.9mm outside diameter) so measure the distance your going to have between your bearings ill send you enough to fit that gap (n youll owe me a favour ... its not the washers, its the dragging my arse over to the post office that youll owe me for )

iv used 12 washers and compressing them about 0.5mm (very light, less than 1kg) i guess you could be a little more aggressive with those A/C bearings but im not sure to what advantage ?? id play it safe and keep it light... if you get any signs of movement slop chatter add a shim etc.
