Moved to AZ from IL. in 1981, but have been a Pakrat, Dumpster Diver and Fixer Upper all my life. Hate to see things thrown away if they can be fixed and saved for another day. When I restore my projects, usually Vintage woodworking or metal working machines; I then Post them on VintageMachines.org. Website for all to see and maybe use my pictures for their Research as I use theirs for my research. And if my experience can help someone else, that's Great, but I must admit, I'm No Expert on anything, I just learn by "doing" and have the scars to prove it. However my restoring is getting slower and slower as I age, but I still like the Challenge once in a while to break the monotony of Life. Here's an Easy Speed Calculator for Motor rpm, motor Pulley size, Driven Pulley size and resulting Speed.
