Oh yeah, that was fun! I ran the shop vac, kept everything greased and poured a quart of mineral spirits through. But after reading some build threads I decided to carefully save the old oil in a clean container, only about 1.5k on it. I am thinking of pumping the saved oil back into the top of the motor with the drain plug out in an attempt to wash more shavings out, any thoughts on this idea will be much appreciated.
