This video is a test of a Shaker Table drive unit. This is a less-complicated driver than a Wilfley-style, but much less time-consuming to build, and less costly. I wanted to see how well it worked before offering them for sale. It obviously worked really well. These are for smaller tables...probably 24" max, though it would only depend on the motor power. I may offer the grooved table decks al...

Hi everyone. It's been awhile since I posted a video. I've been busy, as usual. I spent the winter rebuilding this Coot. I have over 350 hours into the rebuild. it's going to be my prospecting rig going forward. I'm also working on a new dry sluice device. Will be applying for a patent on that in the coming months, so can't publicize it. Stay tuned for video on that. Jim

I've been wanting to build a really good drive unit, for a shaker table, for quite a while. This winter the plan finally came together, and over several weeks of drawing, and building, with many mods along the way, it finally came together. I hope my explanation of how it works is adequate. I may do a followup video with a more detailed explanation, of how the geometry effects the stroke speed ...

This is not a good video. All I was trying to do here was demonstrate the difference in ground noise, before and after, modifying the TDI SL. This was the second Reg Sniff suggested modification, and involved removing two diodes (D20 and D21), and installing a jumper on D21, and removing C56. What this accomplishes is increased sensitivity, but at a slight cost in additional ground noise, as sh...

Testing the sweep speed to see a small gold bar, before and after changing the filter capacitors on the TDI SL. Should see a much faster allowable sweep speed, and still detect the small gold target.

Just posted this so potential buyers can see it running. Jim

Lathe, drillpress, and gear cutter I picked up this week. Looks like a I got myself into a bunch of work...LOL

Been in need of a crusher for quite a while. Decided I wanted a jaw type, so spent my spare time the last few weeks building this unit. It's a Blake type, single toggle crusher, 2" x 3". It's built pretty heavy for the size of rock. 1" side bearings, and 1 1/4" at the center. 1/4" of movement. Complete blueprints, assembly instructions & pics & operating theory now available: www.ebay.com/itm/2...

I bought this old Champion post drill, back in June, from a guy at Dillon, MT. It was a rusted mess on a pallet. Finally got around to a rebuild a month ago. Had to make some parts, including installation of a slow-speed (45rpm) chain drive. The drill has a two-speed gear setup, and runs at about 50 & 100 rpm. Great for running large hole saws in metal. I think it turned out pretty nice!

Taking the sweep Jig down to the Utah/idaho border country to run some old mine tailings in a search for pyrite nuggets. Sweep Jig will be doing dry separation. Tough test as pyrite isn't near as dense as gold.
