since every part I seem to touch on my M-1 either needs painting, cleaning or repair,
I decided to start documenting all this.

it might be nice for others to have dimensions and common descriptions for parts that we only see in manuals and parts lists as a number (like S3A42/8221042 is a 3/16x1 inch square shaft key)

basing this off the parts list from the 1952 manual

I have enough technical training that I should be able to whip up some cad files for parts, so someone could (possibly) build a from-scratch replica


I haven't found anyone doing this already, and thought it would be good to set up a parts list that is a bit more descriptive

requests for specific parts appreciated

I need to order these as the pulley bushings on my machine aren't there anymore, and might as well try to get replacements for the axle too

S2A43 axle bushing 8191043
for 1-3/16 (maybe 1-1/8?) OD for 1 inch shafts by 2 long high load sleeve bearing

S2A44B pulley shaft bearing 8191044
pretty sure it is a 1 OD for 3/4 shaft by 1-5/8 long (looks like porous bronze, your choice to go to high load)
