The only 1mm thick M10 washers you can get are aluminum crush washers

This kit is overkill but look for bike axle spacers. spacers are not washers, spacers will be machined so that the faces are exactly (within tolerance) parallel. Washers are just stamped from sheet and the little wow they COULD introduce into the wheel stack up COULD kill your bearings by forcing them to rotate out of alignment, probably nbd but im tired of replacing my bearings lol. The rear bike axle is e often 10mm but not always so check.

What is the diameter and thread pitch of the bolts, do you know?

Alright fellas. Anyone around here run 200x75 Phatty tires with their m1-AT?
My existing drive screw/spacer setup leaves about 1-2mm of space between the tire and the drive. Do you think this is rideable? I’m not sure how much the tires will flex under normal riding conditions.
Otherwise, best solution is probably just longer drive screws and a bigger spacer, right?
200x75
200x50 for comparison

Welp.
The left side of my drives decided to be cool like the right side.
Here is hoping I can get it cleaned up and going again.
The right side is still looking good.

Seems like the pinion loctite keeps failing on you.
Have you thought about going for straight cuts?

Yep. I had just messaged Kevin asking if they are available yet…
I’d be into giving the straight ones a try…

I have the 3.95 ratio and I like them a lot. Just be aware you need to dremel the mounting plate a little bit to get correct backlash. I do not know if this is an issue for the 3.0 or 5.5/whatever it is.
Pre-dremeling - not possible to set backlash close enough:
You’ll need the two dremel bits below:
Finished and are now able to get close backlash with 21t straight cut pinion:

That’s odd, I also have the 1:3.95 helical gears and there is more than enough travel in the slots, the motor can ‘rock’ back and forth in the slots with the teeth overmeshed

Yeah it was a surprise for me. @poastoast can confirm.
I think Kevin is editing the mounting plate holes for future revisions so it isn’t an issue in future batches.

the straight cuts are indeed a hair smaller compared to the helicals
the helicals are like, 21:83? or something and the straights are 21:82 (3.905
