Very nice HB, works a treat. A local steel supplies business quoted me around $30-40 to get one made up (no handle). I've got a bunch of quartz that needs crushing which you've actually just reminded me about.
Good to see you getting some use out of the pans mate. I found the same thing in that area, plenty of black sand but no colour (what so ever), I'm sure I must have been facing in the wrong direction :/
Nice one HB, simple enough, I am looking for an old hydraulic jack, need a large one I think, take out the pistons and a pre made dolly pot.. just going to bolt the small piston to a rod and it should be sweet.
