i have a keene 2in bkpckr dredge that i have modified to have a under current that lies under the main box.. in the uc it has ribbed carpet and th riffles out of a older keene sluice box.. the water hols are 1/8th inch i think i need to drill them out to 3/16th that way the water flow will increase.. when i used last time there wasn’t enough water flowing out the uc but it did pickup very fine gold. maybe no need for the riffle just the carpet, any suggestions will help
