I like to do whatever I can on my own – including the manufacture of what I need. There is nothing wrong with going to a retail mining store for what you want, but if you would like to try it on your own try building a dry washer. You’ll need plans, of course. There are sites where you can pay for plans. But I have found a place on the Internet where there is an explanation of the use of the dry washer along with photos and rough plan that one could use to build a good dry washer.
Having just gotten my first dry washer I can attest to the fact that you will process more material, and hence, get more gold flake. Don’t forget to metal detect those piles of material the dry washer leaves behind. There’s nuggets in them piles! (Sometimes:) Click below to see.
I have included a link for those of you interested in building your own rocker box. A rocker box has screen for classifying material near water. It has a sluice type construction that water runs down to further classify material. The box containing these elements is rocked while water is poured at one end and runs down to the other.
In an earlier post I drew a very rough drawing of a rocker box I built – included were some photos.
This PDF set of drawings provided by The Minnesota Gold Prospectors is very detailed and very good. Click the link below and download the plans. It’s free!
Perhaps a little easier to see how the riffle box is removed.
