Steel Pan Posted March 18, 2011 Share Posted March 18, 2011 How about a flex plate (flywheel for an automatic trans.) off a Chevy? Quote Link to comment Share on other sites More sharing options...

Au Seeker Posted March 18, 2011 Share Posted March 18, 2011 Charles, Another thing you may want to consider if you can't find the sprocket that you're looking for is welding the individual teeth directly to the trommel's barrel, I've seen a few trommels done this way. This company may have what you need but you will have to contact them to inquire about the sprocket by clicking on the home link at the bottom.http://www.ablproducts.com/60-chain-sprocket.html Skip Quote Link to comment Share on other sites More sharing options...

xt18000 Posted March 19, 2011 Share Posted March 19, 2011 You don,t state how many teeth you want on it nor for what size chain or if you want to use a V-belt. I got mine from McMaster - Carr. You can look them up and fine most anything you want. I had to have a machine shop cut the center out of mine to fit the drum I made, cost me $50.00 to have it done. Then had a welder weld it on a stub of 8" pipe that I bolted onto the drum. Not finished with it yet. Quote Link to comment Share on other sites More sharing options...

homefire Posted March 19, 2011 Share Posted March 19, 2011 To make the coil , they just cut another section of the Pipe in a spiral strip to the width you need.You may find the sprocket here but there pricey!http://www.grainger.com/Grainger/wwg/search.shtml?searchQuery=chain+sprocket+14+inch&op=search&Ntt=chain+sprocket+14+inch&N=0&sst=subset Quote Link to comment Share on other sites More sharing options...

Oversize out the far end GOLD out the near end with no sluice to clean out. Quote Link to comment Share on other sites More sharing options...

What slope will ya start with? :hmmmmm: Quote Link to comment Share on other sites More sharing options...
xt18000 Posted March 19, 2011 Share Posted March 19, 2011 Slope will be very shallow, just enough to keep the oversize moving and any small stuff that is in the coils. This can be controlled with the speed of the drive also. I can run it from 0 to WAY to fast but think to start with it should be in the 8 to 12 RPM range.
