It seems like I modify it every time I get back home. I just converted it to run on propane. I took off the T80 and I have a Gast 263 going on as soon as I get the mounting ring finished. And of course I'm building a wetsuit water heater. My project for spring is to convert to pontoons from a 5 or 6 inch dredge to get sluice a bit higher so I can put a fluid bed on the end of it. I could get along without doing all the changes BUT what else would I do with my time.
By cavitation I mean spinning. When the water spins it mixes everything in the jet flair. If the gold was dropping to the bottom of the hose, it gets all mixed up again. Water can't spin in a square tube. So it shoots straight into the jet-flair, pulling the hose contents straight into the sluice. The gold that was riding up the hose on the bottom stays on the bottom and drops into the beginning of the sluice instead of being blown into the sluice all mixed up and dripping out somewhere further down the sluice. By using a tri-jet you shoot water in at the top and both sides of the flair, dragging the hose contents without mixing it all up.
Ted. How does the square tubing prevent cavitation. There shouldn't be any air in the system and the collector should be pressurized. The reason I'm asking, is I am getting ready to build a twin pump 6" dredge and I have been told that the tri jet is very efficient at creating a great deal of suction. So I am try to learn what I can about different jet tube designs before I decide which one to build. Thank you for your time.
I think it works excellent. As the gold comes up the hose it settles to the bottom. The flow though the tri jet comes in at the top and both sides which drags the gold along the bottom instead of mixing it all up before the sluice. That make it easier for the gold to stay in the first stage. I don't see the quad working for that reason. It mixes everything up. Also if you notice I used square tubes so the water doen't cavitate. Thanks Dan Murphy, for the idea.
I couldn't help but notice the jet flare from gold dredge builders warehouse I picked one up last season for my 4" project dredge and it's worked great. Nice looking setup by the way love that tri jet setup man wish I had that motor setup man that things gotta suck!

There is a guy here on Craigslist with those jets only quads.
That is a very impressive looking dredge. How does that tri-jet work? I've never seen one like that before.
