We could go with oversided fender washers, but I'm afraid that they'll rub the outside of the bearing, thus making the whole thing inefficient. So Andy, when you read this, perhaps that's a viable part for next year (Aluminum spacer for 1/2" and 3/8" hex shafts, either a rod stock or individual spacers).
If you make 10,000 parts, some of them are bound to be bad  |
Inside of the output shaft ... correct.
We have the Keyed output shaft, but internally to the nano it is Hex shaft. We used just a normal (re: round ID) washer to take up the slop and it's running well (we'll do a lot more testing this weekend).
Additionally, I suggest that the nanos get lubricated and run for a time as they seem to need to break in a bit.
While I'm a bit concerned as to the quality of the stuff we've recieved from AndyMark, their customer service has been top notch. My biggist concern is for the rookie and less mentored teams that may not understand how the slop can cause all sorts of failure modes.
