Hi all I have a idea of making a trommal out of 2 or 3 steel rims and a frame and yes I know that it may weight a bit but my idea is to drive to the gold fields dig a small hole and classify all the material and run it through a sluice for smaller bits less than 1 cm squares anything bigger go's on the metal detect pile to be scanned for gold . then return all of the dirt back to where I dug it up from I'm hoping to make 2 or 3 different size of mesh.
Will keep you all posted on progress.
