Length is about 3-4 feet.
The handle is made from 1/2″ PVC end caps and a 1/2″ tee with a couple of short pieces of 1/2″ PVC pipes to connect. The handle is bolted thru handle to the end cap.
Use 1/8″ file for O-ring grooves. Depth of O-ring grooves must be about 1/2 of the dia of the O-ring cross section. Note: I have excluded part numbers as this design is from 1994 and part numbers chance. Because of this you may need to have a poke around your local hardware providers to find an O-ring that gives the best seal.
With the crevice sucker attached, the plunger may be pumped several times until the material reaches the top of the 1/2″ pipe. Another possible attachment would be a 1 1/2″, 45 or 90 degree tool instead of the normal crevice sucker.
Since the gold sucker is normally used with the bottom open, you may be asking “how do you keep the stuff from falling out the bottom?” The short answer is ya gotta be quick. Try to keep your bucket or pan as close to the spot you are working ans almost submerged so you don't have to move the sucker very high or very far. It also helps if you can get into a rhythm where you are still pulling on the plunger while transferring the material. Clean up any material that falls out every now and then.
Credits for the design go to William F Westcott (1994)
