Bearings have held up no problems at all Richard. I've put quite a few tonnes through the little Jaw crusher now and it's been bloody fantastic. Well and truly exceeded my expectations. I have made some minor changes to things also though. I will upload a review video of the Jaw soon, detailing changes and better ideas for others to try. Thats a good idea mate, even just a little welded plate behind the bearings each side would be very handy. That would remove the slop from the bolt holes. I have the bearings pushed all the way back towards the motor for this reason, but little positioning plates behind the bearings would be much better. 👍🏿👍🏿
This video is great. it shows that if I have all the gear and do a lot of work in a great location I can make about $50 a day. So as much as I want to do this and would enjoy making and testing the gear its like all hobbies. Expensive. keep the videos coming I'll enjoy gold mining from afar.
G'day Jenko, you can remove the silver quite easily with some chemistry. But it does require some basic equipment. Research "Gold Inquartation" to learn the process. Inquartation is the easiest way to remove your silver, it will involve adding more silver to the mix with a melt, to bring the silver content up to around 75%. Once there is approx that amount of silver in the mix, you can easily dissolve all of the silver off in some hot dilute nitric acid. Leaving just the gold sponge behind. The silver can then also be recovered again with the addition of copper to the waste solution. The copper will replace the silver in the solution slowly, leaving you again with near pure elemental silver in your beaker.
Dude I watched this in its entirety a long time ago but i forgot or was loopy. Your execution and design were spot on, and you really did a good job! I've mocked up an 8" pipe with 1/4 steel plate backing, and just gonna swing shackles and chain. Running off corded right angle grinder. But I'm fricken lazy
Thanks heaps Aug! I'd really like to see a vid of your mentioned crusher in action by the way mate. I get all my ideas, by seeing everyone elses ideas come to life. So it's always great to check out another build 👍🏿👍🏿👍🏿
Yeah man same principle of sideways hamburger. Outer plate just all thread bolted and sandwich the pipe. Need a fill tube, maybe 2" steel pipe. I lack a welder. Have a little experience, training, but being a carpenter a welder is low priority. But now I need one damn it! ✌️✌️⛏️⛏️ right on bro! It's definitely a lifestyle
Had that happen a few times over the years 😅. Not for a long time though, I'm careful with the positioning. Finding the perfect balance between a safe spot for it to sit, that's also close enough to the water to reduce load on the engine and in turn, save on fuel costs 😁
This is awesome, I have all this steel around to build one but having trouble finding eccentric shafts and bearings to match. Any pointer where I can get some?
The eccentric is really something that will need to be manufactured by your local engineering/fabrication shop Beefer. Or if you have any friends that own a metal lathe, go visit them and draw up some designs. Bearings are about the easiest bit usually, readily available online. But if you get stuck, ask the fabrication shop to source them for you when they do the Eccentric 😁
I went with a 10mm difference, which more or less gives me a 20mm throw. 30mm diameter either side of the 40mm centre. I would go with a 15mm difference if I did it again, giving it a 30mm throw. I wasn't confident my engine was going to deliver the power it needed at that time. But in retrospect, it would have handled it fine with the pulley ratios I'm currently using.
The knuckles are the biggest issue. They flog out very quickly, so we ALWAYS tape up the knuckle so it's rigid and can't be twisted side to side. They only need to be adjusted vertically as you're going. The telescopic shaft also flogs out very quickly, so we tape over the cam locks and the shaft below each cam lock before use also. Keep an eye out for cracks on the top cover plate and general top area of the coil also, some recent batches of coils have been poorly constructed and are prone to cracking. This renders the detector useless under water. Extreme care should be taken under water also, as minelab only install a basic rubber grommet inside the coil where the cable enters. Some work fine forever, some leak after a few hours of use in the water, some fail quicker! If your detector suddenly becomes hypersensitive to everything around it, you've almost certainly had water enter the coil.
Crazy that you disturb your sluice before getting a catch baison under the end of it. picking up the black mat over the v mat likly lost some gold and also change in velosicty of water goofs up the retention behind the riffels. Like your trommel very much. Seems to me water flow under the riffels through the miners moss will hinder gold retention. I used a highbanker with 35 feet of sluice and friend were amazed that I had gold all the way down it. Have to compliment you however not kicking over the concentrates pan hauling the pump and trommel passed it, that's my usual trick. Curious would it not been more productive to have used time spent paning cons on the creek running another 20 minutes through the trommel?
Video coming soon to hopefully put an end to this myth mate. I've been slowly aggravating people with that one over time, with the intent to clear that issue up 😁
2.25 grams for fifty buckets makes me feel a bit better about my last efforts . But man your gold is sooo much chuncker and prettier than the flakey stuff I get over this side of the hill.I remember making multiple trips to cart my trommel in and out of spots too. What a pain when you dont have enough fall to run a river sluice. great video as always Bryan.
It certainly is beautiful gold hey Jethro! Were only about 500m from the structure it shed from, so that's why. Seems there is another reef close by also, purity of approx 75% if I had to guess. This gold looks to be 97%+. Which is very nice colour indeed 😀
Good stuff mate, are you testing your sluice tailings? If it was me I wouldn't be altering the flows with my hands while the water is still streaming..
Thanks Darren! I didn't sample my fine tailings this time, no. I rarely do, to be honest. I stopped worrying about losing gold about a decade ago. Did a heap of experimentation with sluices, flow, and feed rates to establish recovery rates. The end result was clear. Gold doesn't like leaving the box. Bugger all of it even makes it into the blue miners moss, let alone coming out the end. And I always "swish" out my boxes by hand to reduce volume. Many years ago I lost a big flat flake by being a bit aggressive with my swish. But that was in a clean up sluice with 10 or so grams packed into it. Like I said, gold ain't easy to kick out of a good box 😁
@@TheGoldmansChannel thanks for the reply mate, I realise you know what your doing! Your mat set up would rarely loose gold, and you would of tested the F out of it, I'm just envious I can't use a trommel or highbanker legally up north🤣enjoy your videos mate👌
Nsw I gather? I feel for you mate! The rules up there suck. No doubt Vic will suffer a similar fate before too long either. But I won't stop diggin' either way 😝
Nice job, how good is that bleed valve on the pump, reminds me of my bathroom in the 80’s.. nice to have some water to run the trommel, thanks for sharing
Cheers Jeff. Yeah the top tap is a ripper isn't it, it came back to me like that after my friend Jeff borrowed it recently believe it or not 😆. It did have a modern 1/4 turn washing machine tap on it when I dropped it off. But I like the old one heaps better haha
Cheers mate! GOD drives the turmoil I've been told. Gold, Oil and Drugs 🤣. But a little petrol motor like a GXH50 drives the Trommel. Spider coupled to a worm drive reduction gearbox, and chain driven from there.
Seems to be a bug with the comments section sorry folks. Ill try to pin this, so you're all aware. Please feel free to comment, hopefully they become visible to everyone soon
Why do you take apart your sluice box when your water is running? By taking it apart while the water is running, the low-pressure zones become high-pressure zones again, causing your gold to flow out of the box again. I really think you should check your rock tailings. I love mining videos on RU-vid! I have never seen a miner disrupt his sluice box when the water is running. It gives me the when I see you do it.
You'll just have to trust me on that one mate, but seen as this is a comment I receive quite regularly, ill actually do a video on it, and we can all bust a few myths 👌🏿
