Hand Dredge/Sucker Pump PVC

[itmaiden]

I thought my idea was at least partly original and then found out others before me were already making "hand dredges" out of PVC. I am not totally satisfied with the few I have seen on the net except for one "store model" which was way too pricey.

So does anyone have any instructions/diagrams for making one of these so I can suck some gravel out of a sandbar without using a battery or water operated pump. Just want an air/vacuum pump type of deal which is lightweight and fullproof. Would like a couple different diameters. Maybe a 6/8 inch to a 2 inch ? All materials need to be waterproof.
Would like to be able to use it in the water too.

I really like this design but have not had the time to build one yet.

Thank you for the video and the link. A little bulkier that I had in mind, but yet better than something else I had planned. Definitely could be added to my "tools".

Google up - Sam Radding. You want Sam Raddings Book of Plans Volume II. Pg. 16.

Very well done drawings & descriptions. Materials are cheap. PVC pipe & a couple of fittings & a heat source to soften the pipe. Hint, carry an extra O-ring. Just about every mining & prospecting store I've been in has a copy or two on their bookshelves. If you build two of the projects in his books, You're almost guaranteed to pay for the book in savings building your own.
