Use for all my salvaged electric motors and switches

[Jon]

The simplest build is going to be bench-mounting a motor and adding a chuck. See here: Bench motor

For sure belt sander will top the list. The nice 2x72s are thousands of dollars new, and the most expensive component, the motor, can be salvaged from a free treadmill. Salvage the speed controls too, to control the belt sander motor speed. Also salvage the incline motor from the treadmill; it can be used to tension the belt. Along the same lines: weightlifting benches can provide frames for tools.

Here's a good video on wiring salvaged motors:

Ha, wish I could help, i have probably 200 motors, everything from a few volts DC to 220v 3ph. Buckets of switches, boxes of power supplies etc. A few things i would like to make are: tapping machine - from an old Craftsman "hand drill, drill press stand" and Snow tapping head, Lapping plate, slow speed wet grinder, tool post grinder, Mill table feed, etc. Would even like to add a stepper motor and rotary encoder to my rotary table. Which will give it 14,400 positions with a 1:1 ratio. make gear cutting and indexing very accurate. You come up with any great ideas let me know. Anything under 18v look into old computer power supplies cheap and powerful.
