![]() ![]() Of course safety and caution are top priorities when working around power tools and open cutting blades. I used some wooden braces to keep the pipe steady, and made the cuts by using one hand to hold the pipe on the blade, and the other hand to rotate the pipe slowly. The goal is to make a nice groove for the O-ring, but not to compromise the structural integrity of the PVC pipe too much. To cut grooves for the rings, I used a table saw, and adjusted the blade by holding the pipe flat on the table top, and lowering the blade until I could see that it would only cut about halfway through the plastic. The best way that I know of to make an air-tight seal, is by using some rubber O-rings. There is just a little gap, but we actually need this to be air-tight to make a proper piston. Then twist the black knob clockwise to tighten or loosen the nut to the desired tightness.You can see here that the 1" pipe fits closely inside of the 1-1/4" PVC pipe. To do this, simply pull the suction nozzle off the unit and while holding the black knob attached to the end of the rod tightly with one hand, use your other hand or some long pliers to reach into the suction chamber and secure the wing nut. Please note: If the nugget sucker loses suction or is too difficult to operate, you may need to tighten the wing nut inside the suction chamber. The vacuum chamber is 2" x 25" inches and the total weight of the unit is only 2 pounds. The non-motorized suction dredge makes it perfect for places where you cannot use motorized dredges (check local laws). Narrow nozzle allows you to get deep inside cracks in bedrock to get told that was previously out of reach. ![]() ![]() Made by gold prospectors for gold prospectors, this hand operated gold dredge (sometimes called a gold sniper) is made of 2 inch PVC pipe The Ball-handle is made High Density plastic. The 1" x 8.5" nozzle is perfect for crevicing and sniping. ![]()
