[QUOTE="jethro, post: 474155, member: 1297"] Smokey, The best one Ive seen was made using an old fire extinguisher, (The type with a large diameter brass screw off cap ) and a hand operated diaphram type Bilge / priming pump. The pump was mounted to the side of the extinguisher and pumped water/gravel into the cylinder. the heavys settled into the bottom of the extinguisher cylinder and water was discharged out the pump outlet you just kept pumping until the unit was about 2/3rds full and then unscrewed the cap and dumped the contents into the pan.
