I know it still comes down to getting the old pan out but I was wondering if any of you ever used the above Trommel?
I know it’s been around a long time and I’ve seen videos but I want to hear from someone not selling.
I was thinking maybe of running the material out of my drywasher.
Any and all opinions appreciated.
I can't figure out a reliable way to re-mount this pick handle. This is a small pick (USA quarter on left, Australia 1943 penny on right, for scale). You can see what I tried -- wooden wedge in the long direction and steel wedge in the short direction. This didn't hold worth a nickel.
Given that this design has been in use for well over a century there must be a solution. I can't be the first person to have this issue. (I looked online without success.) Any advice is appreciated.
Its been a while since i posted last. Recently i did a comparison video of the Proline and Keene full size 4 inch dredges. It think it is a great resource for those looking to buy a dredge in the near future. I go through each component and talk about my reasoning and though process behind why one is preferred over the other. This is definitely not a video for fanboys of either brand lol. The main point of it is to get potential dredge buyers thinking about there intended use of the dredge and how various features on either one may be better for there intended use.
Hope yall enjoy and please leave any feed back. Discussions are the reason im here !
So we did end up pulling that old 8" out of the bush from an old mining camp (previous post). We're going to go through the whole thing and get it back up and running. Main question I have is about sluice box design. I've read "The Clarkson Study" a few times over the years and just re-read it. Did a bunch of googling, youtubing and searching forums, but its hard to come up with great information about sluice box design for a larger dredge like this. I like Keene's sump system for fine gold but I wont be building that. For the most part I'm going to use this on our claims that are on a larger creek. We do have fine gold but not a ton of it. What we do have is potential larger gold (1-5oz nuggets). Most of the gold ranges from 30 mesh to 4 mesh.
Looking for links to good information and/or input on ideas on how to put a box together. Sadly when the old AMDS forum shut down I stopped keeping up with any other forums with new information after bouncing around a while. I can build/fab just about anything needed. Also curious to what you guys think about some new types of matting in a large dredge. I have all winter for the build.
Box is 9'x34". 1st 3 feet follow the flair angle till it meets the max width of the box. The old riffle set up leaves a lot to be desired. Had been thinking I wanted to do some smaller woven screen at the last few feet of the box for smaller gold and then talked to Mark Keene. He said they have been testing 1/4" woven mesh (1/8" thick) over expanded metal and it was really doing well. Dropped the water flow to 1/2 the rate when the screen was 1-1 1/2" above the expanded.
Was thinking 1/2-3/4 woven mesh for the first 2-3 feet over a combination of Hungarian riffles and expanded metal ( separately, not on top of each other). Then 2-3 feet of just hungarian riffles. Last 2-3 foot maybe run a section of 1/2" woven mesh and then 1/4" woven mesh over a combination of smaller riffles and expanded metal. I would like to make 2 sections in there for some hog mat maybe. Also curious what you guys think of just carpet and moss over carpet in some of these different sections, what size riffles and expanded for the different sections also.
What do you think about this equalizing power jet design and hose attachment to the powerjet/flair.
Dredge came with four 18hp Vangaurd motors and two powerjet/flairs.
Any opinion on any part of this or links to information is appreciated! Thanks
Hello everyone on here.
Im looking on upgrading my Subbie sluice box into a more efficient one.
I have been looking into ideas of what others been doing on here and any suggestion of how should i design a larger Gold nugget trap.
I see most sluice boxes with tiny riffles and i could just imagen a larger nugget go run straight out the back.
I tested my sluice with a almost 300 gram copper nugget and i lost it.
Now we are trying to upgrade the sluice because where we dredge we could find larger nuggets.
Im thinking of placing a section with taller riffles like in the picture with the rails only going half way or 3/4 of the sluice and leaving the same size riffles or making it bit larger at the end of the box for the larger nuggets.
Been a long time guys... Found an old 8" dredge im thinking of bringing back to life. Curious if anyone recognizes this make/model of dredge. Owner says it has keene pumps and thinks maybe tecumseh motors but not sure. Have a couple of pics but wish I took more. Motors were in a locked cabin so I didnt get to see them yet. Planning on picking this up in a couple of weeks. Will be a long trip to get. If anyone has any info it would be much appreciated. Thanks
