Build a hand trommel



Mike's Trommel

Here you'll find directions to build an inexpensive, compact, and light weight hand trommel. It is designed to classify quantity material for your dry-washer, sluice, pan, or garden, and can also be used as a worm harvester. The cost of construction is around $50.

Looks like 5-gallon paint buckets have been cut up and attached with screws. Not sure but that looks like schedule 40 PVC. I'd probably want schedule 80 at least.
The handle is very ergonomic. It needs a better grip contoured for the hand. The 90 degree connection between the crank and shaft is weakest point. I suspect it would slip or break before anything else.

Re: Build a hand trommel

You might want to check out the site posted. It shows a breakdown of the parts, costs, and directions to build with numerous videos showing it in action. I've used this for a season. Handle works great with gloves as well. Haven't had a problem yet and found gold to boot! Imagine that! The neatest thing about this is it's weight. Last weekend it processed and filled (26) 5 gallon buckets ready for the drywasher in 4 hours.

Re: Build a hand trommel

Mike's trommel is a great idea and looks easy to build. I am going to give it a try.

I hate shaking those buckets to classify. This looks like it is so much faster and easier.

I like the light weight feature too. Here on the Klamath many places we want to work are very difficult to get to.

Re: Build a hand trommel

You know Mike,sometimes putting an idea in gear takes a bit of time.These construction tips along with the clever little trommel you created are a great starting point for an upgrade for a heavier duty yet less portable version.

I could even invision a flywheel with handle for a larger
more stationary unit.Maybe the end of a cable spool with a lead insert or two in the perimeter would provide enough momentum.Then it becomes a two man operation of course.

Everytime I pass one of the cylindrical,metal trash containers outside storefronts,I pause to study them for trommel barrel use.Some are punch screen while others are square or slotted mesh.All would be used in combination with water because my material is always wet unlike yours.

A highbanker serves my purposes now but your idea is aces for some areas and purposes.Thanks for sharing it.

Neat and quick.
Just an idea. Look at the cross coupler on the handle end where the handle/axle passes through. Put one on the bottom end and pass the axle through and then make a water swivel on the end. Drill some holes in the axle for use as spray bar.

Re: Build a hand trommel

I thought about a highbanker the same as a drywasher. This unit works great for both. It's a handy lightweight classifier for your sluice work as well. I think it is a good beginning for many ideas. I think the plastic construction lends itself well to wet conditions. Cheers, Mike

Re: Build a hand trommel

I think that just might work! I built a sprayer bar from the top and also sprayed into the hopper which worked well on a recirculating sluice but a little wet and messy when the wind blows. It would work fantastic in a river where the runoff wasn't sent back through the pump. I haven't seen a hose adapter that swivels very easy under water pressure. That would be a great experiment!

Re: Build a hand trommel

Jim ......... you stumbled on the single most important reason I invested my time and energy into this trommel. My arms ached at the end of each day from rocking buckets and spinning classifiers. I had my son weld up a rocking machine which worked better and the buckets weren't self destructing anymore but when the buckets filled the rocker was just as hard to push and they got stuck in the rocking device. I couldn't believe how fast this little trommel classifies! I'll never go back to bucket rocking again.

Re: Build a hand trommel

I'm going to build one with a piece of electrical conduit as a center shaft. I'll get one of my electrician friends to put a couple of bends in a 4' piece of 1" galvanize. It shouldn't add too much weight. I may also expand the entry shroud to take a little more ore and add a rectangular funnel underneath.

Sounds like a plan. Post a pic when you're finished.
