Great Job! Very advanced concepts turned into everyday/everyone doable builds. BUT you've saved us a terrific amount of time. Well done and thank you!

Really lookin forward to that stamp mill.

Really like your builds.

Your getting every single piece there ha ha! Thanks that was interesting, your on a roll!

Awesome as always!

Interesting build you have going on

Keep me posted on the microscope, the table and stamp mill are coming along nicely!

Ive been wondering why gold prospecting pans don't have clear plastic at the bottom. It would help a lot if you just want to know how much gold is in a pan.

Great video! The glass panning is a genius idea! I add a projector lens under it, super glue it, and also a small triple pod around the lens so easy stay on a flat surface, and for drying quickly a piece of a napkin can suck it moist fast and easily. Thank you for sharing your ideal. Ali from Provience, RI.

Orophilia has been very busy lately :) excellent work :)

What material are you using for your table top and how do you cut the grooves? I have a CNC router table that we might use to crank out a few variations of grooves for testing. I like the idea of using a watch glass for observation of heavy materials. Just by chance I had recently purchased a box of 150mm watch glasses. They are a bit big for my small beakers but now I have a good use for them. Thank you. I hold a 350 acre hard rock claim in the San Gabriels and I need to get it on a paying basis. I need all the help I can get. Thanks again for all your insertional videos.

I just found your channel and find it very interesting. Some years ago I built what was called a "side shaker gold pan" out of wood. The grooves were cut at a 45 degrees angle into the bottom on my table saw so they were like backwards riffles in a conventional sluice. Side shaking the pan at a slight angle in still water caused heavies to drop into and be trapped in the grooves and lighter material to simple roll out. Perhaps try that in still water with your groove plate at a very slight angle. Moving the pan under the material instead of washing material over the pan and let gravity remove the trash. Does that make sense?

I've wondered about using a side to side shaker and vertical shaker in tandem. Side to side to distribute the material into a wide area, then vertical to sort by density with riffles depth based. First riffle is deepest, last is shallowest, and all of them cut much like V so the gold naturally wants to sort to the bottom and lightest material should be kicked out into the next riffle. Riffle width would probably be based on how long you want to run before cleanout. Only thing to figure out is what vertical vibration frequency and amplitude would be best. Probably would change based on gold size. Also might be interesting to try the vertical shaker as a pan, gold should sink to the bottom and can just keep feeding material on top of it through a classifier.

Looks like your tape has been released a little prematurely. But will be great to follow your progress as you attempt to optimize your recovery. I feel amongst many issues is your feed rate. Sure it is nice to get the job done as quick as possible , but if you are losing an unacceptable amount of gold , then something needs to change. A question that may be difficult to answer , but is extremely important , is , "Why is not ALL the gold caught in the first chevron ?" Try to determine where the escape is occurring. Is it at either end , is it from all along , or is it over the top ? Should it seem it is over the top then possibly deeper chevron could be considered , or wider , or increase in water flow or slower feed rate ( which could be compensated by a wider table )

I don't think there is enough liquefaction there to keep exchanging the gold for the other particles. Maybe some sort of asymetric shake like when one taps on a pan could help in "jigging" the gold back up the table to a collector while at the same time help agitate the material? I suspect the lack of agitation is why the gold migrates so far down. I made this self-classifying foldable sluice for a goldtrip here, (Not me in video, it's a stunt-golddigger while I film...) kzfaq.info/get/bejne/nNimZaWdmKyrp6M.html The amount of flow and force required to agitate the fine particles under the top mesh section in this sluice is worrying, but it catches very fine gold, and anything big enough to not go into the second mesh size stays on top of the mesh. The plan was for it to be caught in the open section after mesh but it just stays put. That's gold pieces about 0.3 grams not moving while rocks the size of a half donut runs off. The fine stuff is caught in the first 2" of vortex pockets so it's not really any point of the bottom section except for as a lid when it folds.

sir, can you video spesification make to table?

Why do you have the space between the chevrons open? Won't the gold get to the end of a chevron and flow off to the first groove? That's what the gold in a shaker table does. Alternating overlapping chevrons? Wouldn't they concentrate gold in the center better? ...but you may see something I don't.

Just from what I saw it looks like to much pitch on the table what are you thinking on that ?

For gold that fine, have you considered a miller table?

Did you recover all the gold?

Can wee make microscope for field testing . Camera microscope is good too I like ! But in the field you need have battery that last for all day. I use Chinese stuff and getting angry all the time batteries die In 2 hr
