Info on Thompson Drywasher 12V?


Chuck Thuemler

Recommended Posts

I would like to get a 12 volt Drywasher like the Thompson, but Bill isn’t making them anymore . 
I have a small sheet metal shop and can build one , Bill’s Drywasher seems to get very good reviews . 
So if I don’t find a reasonably priced used one I will make my own version . 
I have only seen a few photos, and a couple of videos of one . I would like to get some dimensions.

box width, length, depth, length of legs , pitch angle . Improvements you would suggest from experience?

Thanks , Chuck

Still need those measurements and closeup photos?  I got one recently, worked it a few days in the desert and got some nice color with it.  Such a great little machine! PM me if you need help. Maybe we could trade help, I want to make a small sheetmetal 4” hose bucket manifold for a blower (want to make a vacuum separator).

7-8 years ago I bought the rear legs and motor  from Bill and still have it// I would love to find a crank model to put them on or enough specks to build one. Perry

Hey Anthony, I've been looking everywhere for this exact design. Is there any way you can email it to me @ joseph_thomas_88@outlook.com ? I can't seem to send a private message but I'd love to try my hand at building a well designed drywasher! Thanks and heavy pans 𐃞

I would be interested in funding a Thompson clone & producing them. Would need to check legalities first but I think the market is there. I'm surprised someone hasn't taken over the business. I almost bought a new one back in 2015 at the Prospector Shop in Orroville Ca but didn't. Still kicking myself. Great for testin gravels in dry, remote areas.

   I would also be interested in funding a small trommel build & sales. Something light & portable and production of a yard or two per hour. I also would be intersted in funding a small scale placer gold mine start up on proven ground.

I like the homer bucket tromel design myself, very portable and cheap to make. But there are some modifications one could make on a tromel that size, including a back screw to keep material tumbling around more in it, a wash system or maybe even putting a small conveyor to lead it up to a dry washer. I’d think that would make it a very popular item.

Mad Mining bought Fred Thompson out and started selling his own version of it, and maybe I’m wrong, but I don’t think he’s making them anymore either so you might want to contact the owner of Mad mining.

Sorry about my reply using a homer bucket trommel, I didn’t see your capacity specs!

A yard an hour would kill my little bucket trommel and more likely the operator at the loader controls!:Diggin_a_hole:
