Monkey Motor: Internals

Started on the motor proper by installing new bearings.  Though I had gotten the sealed 6004 by mistake, but figured I'd drop it in for now just so I could continue working.  The 6204 was correct and went in easy.

But went to install the mainshaft and it simply wouldn't fit in the recess.  Closer examination showed there was some damage to it and the lip had sort of "curled" in a bit.  Unsure of the right way to fix, but ended up just sanding the edge down.  Didn't take much and was able to insert the shaft and it turned freely.

Close call, as that would have obviously rendered the case useless if it had been worse.
