My trommel build ( NEW VIDEO )

[jog]

Have been working on this project for close to three weeks now. One of my claims has a lot of old dredge tailing's and I am going to use this for doing my testing.

your rollers look like rubber, you might want to swap them for a set of sealed bearings. they'll make more noise, but will last longer. IMO

Jog, must say that looks great to me.
I see some sprocket teeth on the drum, can you tell me how you went about doing that. I know it isn't complete what have you picked for drive motor and pump/motor?
Are you going to run an under/over sluice for further clssification?

That is terrific build. Really like that hopper.
I enjoy building stuff, too, and have fabricated and built alot of my own dredging related equipment. I'm a DIY'r all the way
Might need to go and make something like this till I can dredge again in Cal or should I say IF. A BIG IF.
Maybe something a little more on the larger side for production yardage.

OK... What I did for the drive gear was found a sprocket big enough that I could cut the center out to fit the screen, then bolted it on to some brackets that are welded to the screen.
I have a Honda 5.5 with a two to one gear reduction unit. Picked it up for a $100.00. So far I have less than $300.00 into the whole project. Am looking at getting a 2" to 3" trash pump for pumping my water.
I am trying to make this unit a lot lower than most others for easy shoveling. I am going to run a sluice so that I will be able to put it on either side. My tailing's will drop out into a wheelbarrow so I can dump them and go over them with my MD, at a later date.

The rollers are scateboard wheels. they are rubber but there real hard and they have a sealed bearing in them.

[sniffer]

I didn't know that. they'll probably work great. good luck and let us know how it works

[strickman]

very nice build jog , that should work great.

[eureka77]

That is sweet indeed man! I sometimes daydream of making something like that with the sluices, evrything set up and running and find the paystreak!
Good job on the ingunity!

Jog, it looks great. Cant wait to see it all put together and getting you some Au. Thanks for sharing!

[jog]

Thanks to everyone for the comments. I'm at the fun part now, gearing up and mounting the engine. I will post more pics when I get a little further.

[jog]

I forgot to show the pic of the fold up hopper. This will make it shorter for transporting and let me get to the engine which will be mounted under it.

thats sweet
looking forward to building mine, will be using ABS for the trommel with a metal frame.
Did you use Stainless?

[jog]

Just metal!

Harbor Freight sells 2 1/2" water pump with a 6.5 HP motor. The motor is a Chinese Honda clone. I have had one for several years and it still starts first pull. When my hookah flipped over in saltwater (my fault) I replaced the 5 HP Honda with one of Harbor Frieghts 6.5 Hp also and itstarts first pull every time. Plus the tank holds twice as much gas, for about 6 hours of run time, instead of 3 before (never more than 3/4 full for no spillage.) I think the pump sells for $165 and sometimes is on sale for much less. Plus they have coupons for a 1 time 10% off anything.

The problem with the chinese clone motors is that they have no quality control. You could get one that runs better than a real Honda or you could get one that is full of problems and completely dies within a year.
