Custom Two Speed Gearbox

(Depending on your confidence in the mechanism, this may be an unnecessary tradeoff.)

Can you please elaborate on how I should go about ensuring that I design the high gear to slip at stall?

Are there formulas/a calculator/white paper that somebody has written describing this phenomenon?

I'm using Blue Nitrile Tread from McMaster. However, I do not know the coefficient of friction.

Thanks
