    Puffer pulley size

    Hello, been building a drywasher, im using a wiper motor with gear reduction maybe 25-50 rpm. For those who used this style what size pulley are you using on bellow side. Currently running 2 1/2 to an 11 inch. I was thinking a 5 inch would be an happy medium.
    Thanks, StrebsClick image for larger version.

    My Whippet runs in close range of 100 strokes per minute if I remember correctly(?). I would say at least shoot for 1 per second.

    If it can't be grown, it must be mined!
