Quickly sketched this ...

Thanks for the explanation. It's good to have it presented so clearly.

iv got some 8mm id A/C bearings but they are open (as apposed to sealed) so for now ill stick with the skate bearings
it would be nice to seal the nose and have a nice light oil swishing around in there :)

still a bit of work to do on this but it will give those that are interested an idea of what we have been on about

My ER11 10mm shaft turned up,, nice tight fit.. i may loctite it when im happy

Iv decided on one double row A/C bearing for now... i left room in the housing for two just in case :)

i ran it no load for ten mins... the bearing gives off more heat than the motor but nothing to drastic, if i remember correctly up tp 110 degrees is passable... it was nowhere near that

I tried to keep the housings 43mm but it wasnt really pactical
i havnt fully decided on how to setup the small motor, iv considered inserting an engraving bit straight throgh the motor but im struggling to find engraving bits with enough length to allow for more bearings on the nose... i may modifiy a needle vise....
anyway the engraving motor is not overly inportant to me but Its killing time while i wait for parts for the main build

just got to hope they will work as well as they look :)
