The New Build.

[TheFossickingKid]

My mining season is starting soon (winter months) and with the holidays getting closer I've decided to start a new project. This project will be the Hand Operated Trommel.

I will have a spray bar on this trommel which will be located above the hopper. I plan to just run a bilge pump on this.

Give me some feedback on this as it will be greatly appreciated before i start building it .

Thanks.

Are you going plastic or metal TFK?

 

[TheFossickingKid]

I plan to have it plastic.

Hi,
I'm going through a similar process using 6" pvc pipe with holes drilled instead of mesh using 2 different size holes and a seperate sluice for possible gems.
Have converted a Bunnings water trap as a feed hopper (cheap and easy)and plan a single spray outlet to pound the gravel. All experimental and easily modified (I hope).
Want to end up with something light and portable (maybe motor driven.

Have seen a good Youtube video on one similar to your design which I thought was very good using pvc t pieces as bearings for centre shaft, greased but not glued for easy replacement.
Also noted they used bungy cord to locate the legs similar to a dome tent. Try Google search/ Videos.
I intend to keep mine on the small side as I will probably be the only one operating it.

Cheers and let us know how you get on,
Bob

Hi TFK

I dont have any comments on the trommel , however it might pay to draw some fish in that river in case you get hungry while youre at the creek.

fresh fish for lunch would go a treat when youre putting some hard hours on the shovel

Got myself to Bunnings this arvo and got myself some PVC pipe to build he frame for the trommel.

Design is looking good TFK, hope it comes together well.

You should get yourself some 2mm graph paper from the newsagency, it makes it so much easier when trying to design & draw something & you can get it more to scale etc. A small ruler helps as well & you can get all your angle & lengths correct & straight.

Thanks ozziii, will get some when I'm at the newsagent next.

good work Mister

are you going to put it together without glue first , tweak it , tune it , adjust it and then glue it with PVC cement ?

 

[TheFossickingKid]

Yea I will most likely do that.

Don't use green glue.
Use blue glue.
If you use green glue,
You will come unstuck real quick. :lol:
Trust me. I know. :8

Heavy shtuff that PVC kid,... lucky you've got a hoist (ha).
Can't wait to see it through it's progression to finished and in use as the cold set's in. 8)

Hay TFK,

I built one of these ages ago but mine has the center axle doubling as the spray bar. They work great.

With the one I've built I've left key points unglued so I can pack it all up within the main cylinder and I can carry it with a strap on my shoulder and I can adjust the front legs to a few different angles but I don't have the bilge for it, good idea

 

[silver]

That looks awsome backcreek !

Yea Silver, they are a good thing.
I used to use it when I was running my highbanker on submersible pumps.
The pumps ran off an invertor from batteries in the Landcruiser.
I used the trommel to classify the material and save run time on the highbanker pumps therefore saving battery life.
If I ever get it out again I'll put a clip of it up.
