Hand dredge leather

[NuggetN8]

Hey anyone on here know how to get/make a leather plunger for a hand dredge? I've been using a rubber ball smushed by a couple of washers and a nut to make the suction in mine but they don't last for very long and I can't always find the right size of ball to put in it. Pretty frustrating I was going to go adjust it and go panning/sniping tomorrow, didn't think the ball would go bad that quick =/

I bought mine from local hardware store for about $6 in the water well pump section. Put the leather around a 2" rubber plug. Had to shave the rubber plug some so it would fit correctly

Something like this:

You can also try cutting out squares of chamois and stacking them. I am experimenting with mine right now.

Alright I might try one of those eventually. Turns out the rubber ball I used just dried out because I haven't used my hand dredge in a while.. after I got it wet and let it soak up some water the suction was perfect xD thanks for the ideas though.

these leather cups are seals for the old hand water pumps, and like was stated ,they can be bought at most bigger hardware stores. i use a circular gasket cutter and cut mine out of butal rubber sheets for my seals! anytime/anysize fits perfect.

Amen Russau and OSH/Capitol Rubber are just a few of the chains that sell the nylon cross thatched impregnated rubber sheeting that lasts purt' near forever in differing thicknesses and durameter so no more piling on needed !! John

Hi,
Did a search for information a year or so ago, and came up with this. Thought it was very good information.
