If you are talking about South Africa uranium... it's a very interesting geology. Where gold ore formed deep in the ground from ancient alluvial deposits, same is true of nearby uranium deposits.

a few things going on with the resurgence of uranium. Last visit underground was about a couple months ago checking out a uranium mine with this fella from South Africa.

Oh, I see it was only a guy from South Africa checking out a uranium mine.

doing a crash course in centrifuges and pretty much settled on on getting a Neffco Bowl but Larry Neff passed away and Global has taken over the manufacturing of the bowl. They want $8000 usd for a new one and I cant find a used one atm. I actually can but then its just the same bunch of guys that like to mine the crap out of the miners

im in Canada and $8000 usd is about $15,000 cad. I dont want to spend $15,000 on a bowl just to see if it works, Global went radio silent when i asked if they would send me one for a week or knew of anyone local to me that could rent me one for a week and if it worked id buy it.

these things arent exactly brain science, its a bowl that spins at 120 rpm using a 120v, 1/2 hp, 1800 rpm motor going to a 15 to 1 gear box. the bowl you could copy cat the angles of a frontier bowl and then just glue in the extruded rubber riffle. from staring at pictures and paused videos i pretty much know the profile but does anyone have a profile pic of the extruded rubber riffle with dimensions? so i can just get it extruded locally or know where to buy 100 feet of it?

Maybe the manufacturer sells replacement parts(?).....might be worth the investment.

Not seeing much in the way of parts. If one wants a number of units may be out of reach for many.

i printed a profile, going to play with the shape a little but its close

want to make it a little beefier to hold up to the 5g's. the rubber riffles in the original bowl this thread started on were thin and flapping in the wind

Will the shape of the rubber support much weight spinning?

you saw the neffco bowl bottom riffle open right up from the weight of the sand, showing the inside "slit". at the "toe" of my design instead of a chamfer ill just make it round so it will match what ever angle the "heel is at. then ill fatten the "ankle" a little bit. i dont think the 5-G's play too big of a factor because inside the riffle it will have water and sands in there mixing around and exchanging but it wont hurt to beef it up afaic
