    puffer drywasher motor?????

    has anyone used a wiper motor to power a bellows style drywasher?
    do you need to use pulleys on it? can it be run with with a connecting rod from motor to bellows?
    thanks for your help, george

    I used a motor from one of those 12V tire air compressors worked OK, just a little fast. Didn't want to bother re-doing it after I got a good deal on a gold duster. If you don't have any, I think I've still got the plans I used.
    I know it's here, just need a bigger coil!

    I think that's good. I only used mine a few times before I got rid of it. I just tried the pulleys I had in my junk bin until I found where the dirt looked like it was hopping down the tray the same as what an old timer showed me.

    Re: puffer drywasher motor?????

    I build "Puffers" (see pics) get motors from www.surpluscenter.com catalog #10-1564 12 volt $6.99, get a
    1"x5/16" pulley for the motor end and a 12" "Swamp Cooler" pulley for the crank shaft end. this will give you the proper puffing speed. do not tighten belt too tight, adjust the belt with an amp meter to load motor to about
    1.4 amps or less. The belt should be the most flexable one you can find. If Surplus Center does not have what you need to build a machine then you probably don't need it! They have a free 171 page catalog and one on the web site too.

    Hey Desertdigger,

    Are you still building these Nice little Drywashers ? I know the thread is an old one , may be that is why I didn't find the mentioned motor on the Surplus website. Can any one help with the "suitable" motor for this type of Drywasher?

    Good day,

    Some of my customers have used these new wiper motors for their home built puffers. These motors are used for Halloween props, etc. The price is good for a new motor, but I've never used them so I can't say on durability. But here is a link to a source of cheap new motors,

    Electric Motors for Props - 12VDC Wiper Motor - Halloween Prop Building Supplies For The Home Haunter - Monster Guts - Wiper Motors for Haunting Needs

    I hope this helps you folks out and the good thing is this company always stocks them, they are 2 speed and no junkyard picking!

    Have a great weekend everyone,

    Bosch/BMW wiper motor with gear reduction from a late 80's/early 90's BMW*. Much better battery time, boatloads of torque for a wiper motor and they last forever. Never found anything better.

    I have a friend who did extensive side by side tests in a controlled set of experiments and he independently came to the same conclusion.

    Hit the junk yard and you can get one cheap. New they run about $100.

    Yea I figured I was gonna have to do that and a simpler control.

    My brother is a mechanic in SoCal... I won't be paying $100 bucks thats for sure.

    I'm building another drywasher (hand lever powered) and was thinking about incorporating a 12 or 18 v sawzall to power it.
    I would mount it (removable) a few inches past the fulcrum point on the lever to get the 6" of bellows movement I want.
    I think it should have enough torque to do this but not sure how long it would last.
    Anyone try this

    thats a cool idea,it mite hard to control the speed,maybe you can use a small ubolt and just tighten the nuts to hold the speed.
    good luck brad
