Then insert that into the 1-1/4' x 1-1/2' bushing. To setup the sucking piece, take the 6' long 1/2' pvc and insert it into the 1/2' x 1-1/4' bushing. This is then inserted into the 45 degree part of the ABS Wye connector.

The other end is then connected to the 1-1/4' to 1-1/2 bushing. To create the collection piece, take the 6' long 1-1/4' pvc and place the undrilled 1-1/4' cap over on end. On the other end, take the 6' long 1/2' pipe and connect it inside the elbow. This creates the seal needed for the pump. Take the pipe insulation and place it over the threads, then screw on the 1/2' cap. Then, place the 1/2' slip to 1/2' thread bushing onto the end. Then put the 1-1/4' cap with the hole drilled in it over the pipe. To create the pump section, take the 24' long 1/2' pipe and pit the 1/2' elbow on one end. That way as material falls down, it can collect inside the part with the cap. Make sure the ABS Wye connector has both ends facing down with the other end connecting to the pump section.

Also check with local laws to make sure you're allowed to use a dredge in your local area.ĭry fit the pieces accordingly to make sure everything is the size you want and that you have all the parts needed.

Use proper safety equipment and common sense. Please note I am not responsible for anything you do, so please only use my instructions as guidelines. This dredge is not my original design, it's based on this: I purchased all of the parts new for just under $23. They allow you to suck up material in hard to reach places, such as under rocks, and in crevices. Hand dredges work extremely well if you are prospecting for gold as they allow you to quickly move lots of material. A hand dredge, also called a gold sucker, is basically a pump that will allow you to suck up material.
