Nobody probably wants to admit it - but that's a heck of a nice looking trommel!

My advice - keep it chained to your leg! :)

lol thats funny geo i am trying to figure out a sluice for it now .i guess it was a good find for 700 just had to drive to nevada to pick it up ...

think i would check into 12ft. long 2 ft. wide plan that is alot more sluice than you will be able to use. I have a trommel a step bigger than yours and push 30 yds an hour through it with a 4"pump I run multiple "saftey boxs" when setting up but same as my large plants if set up right the top couple feet of box has all the gold.I ran a long wide box with every kind of riffle and mats I could find as a secondary for a lot of years before the time to cleanup vs. minute amount of gold that was lost in first box made it a waste. enjoy your trommel and may your pans stay full..ws

yeah thats what i was thinking of building tenderfoot . but was not sure if it was too big or too small or what . any ideas on matting ?

I broke a piece of 1/16th aluminum 18"x 96". I bought 4ft of the deep rib mattting & 4ft of the blue miners moss, for my sluice.After running my 6" dredge this summer i think im going to use shorter(height) riffles in my trommel sluice than whats in my factory keene sluice. I did alot of research and figured i could run 8-10yd/hr. through my 18" drum.Thats about the size for my hitachi ex40 i think. (1/4yd bucket)

do you have pics of your trommel sluice ? i have been getting quotes and one was for 1200 and thats 10 feet long 18 inches wide with stand and everything . i would like to make my own.

a 4x8 sheet of 1/8th plate i think is around$250. local steel shop will charge around$100-$120/hr. for braking the plate.To have no scrap utilize the whole plate.Say 24" bottom, 10" sides, & that leaves you 2" on each top to have broke over as a strengthening rib. ________________

I built a trommel back in the early 80s, and still using it. Built a sluice out of stainless (1/16") last winter. It is 18"x 8', lined with vortex and inch and a half raised expanded.

11-07-2012, 05:57 PM
Hey ted what is vortex ? and why did you go with 1 1/2 raised metal ?

11-08-2012, 05:58 PM
I went with 1 1/2 raised expanded, because I'm screening to -3/8" in the trommel, and that size stays cleared. Vortex matting is also called rough top conveyor belting.

I built a trommel real similar to yours,Looks like a old propane tank, We use a old dredge sluice 20" wide with the dredge ripples with a three inch pump and it works great,put a secondary sluice behind it to check loss and very little ever found.We are using 1 inch screen.The 3 inch pump is just enough water.If I did it again would probaly use the expanded metal for riffles as I think we would not be maxing out the pump output.

ok i just bought a 8hp honda with a wacker water pump pt3a and i cant seem to find were online it say how many gallons an hour it uses .BUt one person that builds sluice boxes said i should go with a 10Lx16w slucie box with 8 ft of hungarian riffles and 1/4 punch plate and the top to soften the water before it flows down the box ? others have said go with a 18Lx10W with bare sluice at top then 1inch raised expanded metal with vortex under moss then 3 ft of riffles at the end to act like a nugget trap ? which is better for the pump i have .

Here"s a pdf file you can down load that covers your pump. http://products.wackerneuson.com/manuals/Repair/117617_001Rep.pdf It shows up to 400gpm with a 3". I'm running 220gpm in my trommel. That allows me to run 10cy per hr.

Hey Simkiss, nice find there. It will pay for itself and the upgrades quickly.

11-15-2012, 05:01 PM
lol the best part is how much i talked the guy down to on the price lol ...

My kid bought a mitsubishi eclipse(used) this summer with gold he dredged.Payed $200 more than he asked to save it for us. Just the way we are.

lol the best part is how much i talked the guy down to on the price lol ...

11-15-2012, 09:35 PM
Nice i paid 200 for my pump lol .

"Score" --- 200 Dollar pump what a Great Deal !!! For that price you can't go wrong ...??? A new 3" Gas engine pump is under the cost of an oz. of gold , wouldn't take long to pay for itself depending on the ground your working .... The water pump is the back-bone of a placer mining operation ... Can't mine with out it , in fact I would encourage miners to have another unit as back up ...

I've known a few Miners/Dirt-work Contractors/Commercial Fisherman who have the "Knack" for finding used equipment for such "Great Deals" ... I don't believe many are mining/contracting/fishing any longer ; maybe, they went into dealing in used equipment or scrap iron ...??? Not sure ...

When it comes to mining in the Alaskan Bush or fishing 40 miles out at sea , I'm a strong advocate of Murphy's Law , the chain always breaks at the weakest link and at the most unfortunate time , therefore I do my best to leave no weak link in my mining/contracting/fishing ventures ... I've learned a few lessons the hard way , when it comes to "Skimping" on the "Tools" that will help bring you success or home for that matter ....

Equipment failures can have a large impact on a man's already somewhat limited season mining in Alaska ... I experienced that first-hand one year ; seemed like every week we were headed to town for parts , I felt bad for the man I worked for ... At today's gold prices that would be a loss of somewhere in the area of 30,000 a day in lost revenue ... If you don't have enough capital to purchase dependable mining equipment it would be wise to wait until you can ... Money can't buy back "Down time" ---- Unless your last name is Hoffman !!!!

lol yeah i am still buying another water pump for back up i just happened to see this one on cl were i live and the guy who was selling it didnt know what he had so i jumped on it so my friend is rebuilding it and tunning it up for me . this season is going to be a good season even if i dont make much at it i love being out in alaska for the summer .

Any chance that you got some of the below numbers mixed up? Your expanded metal should run less water depth and the way it reads below shows a narrower box which means greater depth of water.

"10Lx16w slucie box with 8 ft of hungarian riffles and 1/4 punch plate" , "18Lx10W with bare sluice at top then 1inch raised expanded metal with vortex under moss then 3 ft of riffles at the end to act like a nugget trap"

11-16-2012, 11:57 AM
So the guy didnt know what he had, then you talked him down? Dude c'mon.

11-16-2012, 03:09 PM
oh yeah i was going to do an 10Lx18w but i changed my mind and went with a 10Lx16w with 6 inch sides . with 8 ft of riffles

11-16-2012, 03:10 PM
yup hey its sales . i will always try to get a lower price at everything he was only asking 450 in the first place .

You cant buy good Karma.... jus sayin..

11-17-2012, 05:28 PM
Not trying to buy good karma all i did was talk him down on his price same thing everyone in this world would do . You cant sit there and tell me none of you guys on this site have talked someone down on a price . I mean i did nothing wrong .
