The thing is, I want to keep the driven pulley to be less than 10 inches in diameter. If I use a second drive train, with another 3 inch pulley, what would the 2 driven pulleys be like?

If you drive a 10" pulley with your 3"x1700 RPM pulley, the RPM of the 10" pulley will be 3/10*1700 = 510 RPM.
Now if you put another 3" pulley on the same shaft as the 10" pulley the RPM of that 3" pulley will also be 510 RPM.
If you now put a 10" pulley on the final driven shaft, and drive that 10" pulley off of the 3"x510 RPM pulley, the speed of that final shaft will be 3/10*510 RPM = 153 RPM.
So, to get down to 153 RPM, you need two 10" dia. pulleys and one more 3" Dia. pulley.

I have an electric motor that spins at 1700 RPM. On its shaft is a 1.5 inch pulley. What size pulley do I need on a spinning shaft to make it turn at 40RPM??

Your going to could desire to do somewhat math for this one. 1425 rpm's right down to six rpm's is a few intense help. a three" force equipment has a circumference of approximately 9.40 two". The pushed equipment could desire a circumference of 237" or a diameter of 76" (over 6' !) the two that or a complicated set of help gears or pulleys - i've got not got faith the two could teach very sensible for shifting capability.
