Buiilding a highbanker Options

[rich on western ...]

I am planning on building a highbanker. I'm setting it up for fine gold only. Wanted to make a boiler box with spray bar all around it. Planning on using a 12v bilge pump instead of a gas pump. Was wondering if it would be powerful enough. Was thinking a 1000 gph pump might do the trick. Can you use the pump directly in the stream or river for areas where it is hard to get proper flow? What sized hose should I use to feed the spray bar? Want to set it up with recirculating water so I can work dry areas. It is going to be 8" wide and 32" long. Going to have a 1/4" grizzly at the end where the bigger gravel will wash off. The sluice part will have a 16" slick plate and 2 8" sections of expanded metal over miner's moss. Going to be based off my DFS but smaller to be more compact. Going to make it so it will fold up for easy transport. Any thoughts would be appreciated. Will post pics once I start putting things together. I just have some ideas on paper right now.

Rich it sounds good asis! id use 3/4 inch pvc pipe for your spray bar and drill 3/16 inch holes. id clamp the pvc pipe to the sides and leave them UNGLUED so that you can adjust the spray angel and be able to cleanout the spraybar if it ever gets clogged up. i use 2 750 GPH bilge pumps so that i can vari the water depending on the size of the material/gold good luck and post a picture when done.

Got everything drawn out on paper. Got a piece of stainless steel sheet metal that just happens to be the right size to build everything I need. Got all the measurements down and where to bend it. Just need to draw it out on the sheet metal and take it to my friend's shop who has a metal brake. Also found a good deal on a 1100 gph bilge pump on ebay. Have a question about how long the riffle area should be. Trying to keep it compact but still want to catch gold! Was thinking of making the sluice 24" and the actual riffle are at 12". Otherwise was thinking of making it 16" with a total length of 32". Will 12" of expanded over MM and V at 8" wide be enough area? Or will it clog up with black sand too quick? The area that I work has a lot of black sand and most of the gold is smaller than 30 mesh. TIA

I'd be interesting in seeing the end result! Or even better, a step by step process, eh?

Rich id recommend only going 10 inchs wide by whatever length you want for using this setup. and id make the riffel height short, maybe 3/4 inchs tall. or not even useing riffels jusy raised expanded metal over ribbed carpet. im assuming your in fine gold country and wont need a array of riffels for trapping big nuggets. good luck and post a pic or two when your getting some gold!

Thanks for the advice. Plan is for 8" wide and no riffles. Expanded metal both raised and flat with bigger holes (3/4" and 1/2" raised or smaller). No nuggets around here ever. Will start posting once I get something started. Will do a lot of testing at home before taking it out in the field. Hope to go get some buckets of gravel this weekend.

sounds like a plan!

[Denise]

The forum must have timed you out. It will do that if you take too long posting...........CP says you need to pick up the pace and type a little faster if you want to keep up around here.

I really like your home made banjo Spud. Can the hopper be adjusted if needed? It looks like it does a fantastic job on the fine gold recovery!

[spud]

yes the top hopper can be adjusted to suit either sand or clay dirt

also this spot has diamonds as well --no didnt find any the clay is blue in colour ---strange looking and full of gold as well ---I did find a blue sapphire as well as 2 blue Topaz

[Denise]

Two thumbs for your banjo Spud!

It sounds like you have a fantastic little spot for some nice goodies! Any pics of your pretty blue finds? Did you find those in your banjo concentrates, or just prospecting in the same area? Inquiring minds want to know.
