Yes I have a vibrator for my banjo, but as yet have not had the chance to use it. When I do I will let everyone know the result. I bought it because it sounds logical that any sort of vibration in your highbanker or banjo must surely settle the heavier metals going through the system into the bottom of your catchment area. The only drawback seems to be that you need a 12V power source for your vibrator, eg car or motor bike Battery, which adds weight to whatever you presently have to carry. Its not such a big deal if you can drive up close to where you will be working, but if you have to walk a fair distance a battery gets quite heavy. Bazza
I wonder how hard it would be to make up something that uses water (Like in the highbanker Swampdonkey bought recently).
My mind is thinking about one of those little pumps you drive with your electric drill ??. If it was used in reverse, ie have the pump "inline" with your hose and a small counter weighted setup fixed to the shaft. That way you don't loose any water. Just a thought but I reckon that principle could be adapted.
Everyone has a photographic memory, some just don't have film.
Hi Ric, We are both well, thank you, just recovering from doses of the current flu. I will be heading up to Gemfest at Anakie early August where I will be displaying and hopefully selling some of my gold nugget jewellery. I am not sure about your idea of a counter weight setup, but I reckon as long as it doesn't cost an arm and a leg the best thing to do is make it up and try it out and see if it works. Hope you and yours and all the other members are fit and well except for bad backs from lifting all that gold!!!! Regards to all, Bazza
I have an electric shaker that I made from an old windscreen wiper motor. I sealed it inside a piece 90mm of polypipe and bolted it to the side of the sluice. It runs almost silent. I had scrounged a couple of 6volt batteries from the tip and only one of them would hold a charge so I haven't replaced the batteries with a reliable one.
At Oallen I was able to park my vehicle close enough to use the 12v volt cigarette socket and it did work well.
I also made one using an electric motor from a small 12volt air compressor but it screamed and the noise it made was unbelievable. I soon ditched that one after about 30 seconds of use.
Well as some of you may know I experimented with vibrators a lot, Janine bashed me most of the time....nar sorry On thje sluice it did make a lot of differance, the trouble I had was finding one that was durable enough to last the distance, if it was durable it usually used to much power and drained the battery to quick, I ended up finding a small 12v motor from a battery drill that did the trick with an offset bolt on the drive shaft to create the vibrations. One thing to whatch though was that if you did not clean up regularly it would tend to set the concentrates on the bottom of the sluice fairly hard and if you got a build up you could loose gold over the top of the riffels, this was particularly the case in muudy ground not so much the sandy stuff.
Hi John0, It was after seeing your shaker that I ended up making one. Also I believe that you were the first on the old MSN site to experiment with the catch tray in the riffle box that so many of our sluices sport these days. I think you had a photo of one made with wooden ends and aluminium about 12 to 18 months before it started appearing in a lot of sluices that had photos posted on the site.
Warning!! I may vanish at any instant.......and the time is getting close The Eternal question. Where ? Is your life heading for a dead end?
Am wondering why we would be dragging batteries around when we use pumps with our gear, my thoughts go in the direction of pelham wheels. Am working on one at the moment, got a water activated alarm bell from a firefighting sprinkler system. Someone posted pics of one ealier in the posts. Is still experimental, actually am still building it. Am waiting for a mate to pull the pelham wheel off the shaft, they are compressed on and if you pick one up they need a 3 point puller to remove them, try any other way and you will have a bent wheel.
Live in VIC mate. Thanks greatly for the offer but will plod on with the one I am building. Am going to put an outlet on this one so I can move the water from the pelham wheel away from the work area, thinking of voluting it so that it moves the water away a heck of a lot quicker. Will most likely use a short length of 64mm layflat, depending on what flow I will need to move the wheel at an acceptable level.
