With the larger glued to the smaller pulley and some tensioning mounts made, it was time to test this out!

It works! Turning it by hand and counting the revolutions we now have a seventy five to one speed reduction.

That means that when the platter is spinning at 50rpm (roughly what I am aiming for on the mulling machine (which will be probably be the most burdensome load), the motor will be going at 3,750rpm. That's still not the most optimum for a motor of this type, which is probably more like 7000rpm, but it's a big improvement!
