Thinking about putting together a rotary tumbler.
Have a couple of options for a motor. An old furnace fan motor 1/4 HP 1750rpm I believe or I was thinking about using a windshield wiper motor powered with either an old pc power supply or a an old 12V laptop adapter.
Was thinking two shafts mounted parallel in pillow blocks. Rapping the shafts with rubber hose for grip. If I use the wiper motor I was going to run it direct to one of the shafts. If using the furnace fan motor I will use a pulley and belt setup.
Any suggestions?
Thanks
