[QUOTE="HeadsUp, post: 30084, member: 414"] no , i made the grizzly screen out of 12 x 3 mm stainless flat bar on its edge but found that the 13 mm gaps between the bars was too big for some locations as the sluice got overwhelmed with enthusiastic shovelling on my part and i lost 80 % of the gold on that trip just blowing it out the end of the sluice. I have made another one now with 5 mm gaps between the bars and will try that on my next trip I can change the grizzly screen in 2 seconds which is handy because they do need to be cleaned out of rock every now and then The 5 mm gaps will mean more volume of material going out the tailings end of the grizzly and the sluice wont get overwhelmed [/QUOTE]
