Does this happen under load or only on the bench?

Both, but alot less under load. With all the wind noise and cars you wonât hear it unless you go over 30mph

Or running for thousands of miles without fail if you set them right. Ask me how I knowâŚ

Just like your âwaterproofingâ theories right Brian.

I think youâve got more grease than you do gear drive, was it leaking grease goo when you closed the case 
your drive gear might even be fanning grease into your motor screws lol
What I do is put two or three small dabs of grease on the wheel gear and spin it, than youâre good, just want to put enough to lightly coat the gears. Too much will make drag

At least his drives will be silent since theyâll be running with an infinite supply of grease circulating

And hot motors depending on the amount.

we all have it on the M1s
new or old, itâs likely the interaction with metal on metal small tooth gears
other drives arenât loud as they are bigger toothed and usually have one metal one POM
itâs like the boosted drivetrain system vs 5mm pitch belt systems

so you think if I run the straight cut and the helical at the same time it will crescendo to an earth-shattering degree?

You guys are making me worried, I donât want ear-piercing M1 drivesâŚ
mine have roughly 200 miles on them and arenât ear piercing⌠yet?
I run FS motors also.

Holy shit, your strait rolling. Monster balls!
Mine were like that out off the jump so you should be good. I took apart the gears and spun the motors alone and the sound was still there so itâs the motors. Almost confirms my guess that shavings got in the motor. Even with opening and cleaning itâs still there. Doesnât affect preformance so I donât worry about it, just annoying.

How is it that loud? I have straight cuts and canât even hear them past 20, 25. And what setup?

Helicals not loud enough for me 
I will take straights at 2.78 if available no problem. Pedestrians on bike paths are annoying and nothing like the sound of an electric saw to make em move

2.78 ratio
i havenât regreased it so itâs basically no grease at that point between the gears

Iâve run my M1 gearbox with no grease for at least 400km now no problem, if the backlash is set properly and you check periodically for wear its fine.
