Nicely done; that's a great looking extension to your sluice. I love looking at pictures of home-builds. Over the years, I've gathered some great ideas from what others were able to imagine that I'd have never thought of.
All the best, and I hope the extra sluice area works out great for you,
I do like how yours, it looks really well done. Thats ideally how i wanted to build mine, but limited funds and resources for the moment, college problems. In the next few years i do plan on remaking the extension out of some aluminum and making it look a little nicer.
Well my Internets been down for a couple weeks but in the meantime ive further upgraded and finished my sluice. Got 72 inches of GoldHog matting installed. Ready to get out and start moving some dirt!
