I have almost finished my building my new sluice box. It is 68" X 14 1/2" X 7" and weighs in at almost twenty pounds. Its a monster! I built it just to have a winter project and because I had a large enough piece of aluminum that I could. Don't know how well it'll work but I can't wait to find out! Any ideas on how best to use this sluice is very welcome.
Heres a photo.
