Sasquatch Posted July 9, 2021 Share Posted July 9, 2021 I bought my first dredge and it is an old one, have a couple questions if someone knows old Keene gear. It’s a pretty vintage 3” Keene suction dredge, crashbox, power jet, 14x48 sluice and frame that was strapped to inner tubes. The old Copper BS 5hp with an old Johnson 155 air that seems to be working. Changed the oil, gas, checked the sparkplug, removed the pump and she started right up and runs great. Everything is in suprisingly good shape. The pump is a Keene P-150, I assume pumping in the 200 - 250 GPM range. It has the old paper gaskets for the pump housing, will Auto gasket maker work to replace those if needed? I think the main pump seal is still the same as modern pumps. For the Sluice it has a plate in the crash box then flat red carpet under the riffles. What would you recommend running in there? Miners moss over carpet? Change to rubber matting? Leave as is? Should anything go under the crash plate to help catch fine gold. Would love some opinions. I did clean out about 20 flecks of color from the tiny bit of sand left in the sluice, so I know it can catch some fine gold. Anyone know anything about the Johnson 155 Air compressor? I can’t seem to find any information on it. Seems to be working but not sure if any spare parts are available for it. Last question is what to do for floats. I would need new inner tubes but I may try to rig up something with a packraft I have. Anyone used pool noodle floats? I’m sure the hard floats are best for fast moving water, but curious what other options there are. Would like to keep it light to be manageable by one person and able to be hauled with an ATV. Thanks for any info. 2 Link to comment Share on other sites More sharing options...
Sasquatch Posted July 9, 2021 Author Share Posted July 9, 2021 One more question are regular hose clamps appropriate for pressure hose or should these permanent clamps be used? Link to comment Share on other sites More sharing options...

I am sure that Steve would have the best advice for you when he gets back. You might find something closer to what you are looking for in the database that I have missed. Good luck, looks like you found something that can do the job. Link to comment Share on other sites More sharing options...
Sasquatch Posted July 10, 2021 Author Share Posted July 10, 2021 Thanks, I tried searching but didn’t find much. I know I will be adding a rubber flap to calm down the water flow after the crashbox. 1 Link to comment Share on other sites More sharing options...
Flydog Posted July 12, 2021 Share Posted July 12, 2021 I'd go miners moss over ribbed carpet and use a normal hose clamp on the pressure hose. Link to comment Share on other sites More sharing options...
Sasquatch Posted July 12, 2021 Author Share Posted July 12, 2021 Thanks. Will get some miners moss. Got her started up and looks to be running great. Ran a small amount of rock, gravel and sand through it, and 10 flattened split shot, recovered 7 in the crash box, a couple in the first 2 riffles and one in the 4th riffle. Put some rubber mat under the crash plate, then ribbed carpet under the riffles. Added a rubber flap and tried adding a piece of lexan to the tail end. My thought is it should let me peek at the riffle action, will probably get scratched up in short order but thought it was worth a try. Planning on getting it out this week to try in the field. 1 Link to comment Share on other sites More sharing options...
Ausome Posted July 13, 2021 Share Posted July 13, 2021 I had good fines recovery by putting Daisy Mat in the main riffle section. Use a black marker to show where the riffles set, then a razor knife to cut the mat fingers out so the riffles will touch the mat. Nothing fine will get out, but larger material will work on out. Also, 8" ABS pipe with end caps make good durable flotation. If you need more you can pack it with foam pellets, or foam blocks to help. Good luck, and remember that fines will pay for a lot of expenses, esp, at todays spot price. Ausome (Norcal N. Yuba) 1 1 Link to comment Share on other sites More sharing options...
Valens Legacy Posted July 13, 2021 Share Posted July 13, 2021 Looks like it will be a good setup for you, just get your flotation proper and your all set. Is that your neighbors gold fish pond your using to test it in? Just kidding Good luck and good hunting. 1 Link to comment Share on other sites More sharing options...
