To Building a Simple Banjo

How to build a banjo? The first rule is to use your head in regards to making odds and ends which go tougher fit. A banjo can be as big or as small as you want or need. And a banjo can only be as good as the pump driving it. I can only give you a rough guide on how to build a banjo it will take some time to get the hang of working it. The levels are important don’t have it running to fast or you will lose gold ½ inch to the foot is the fall required or there about. How you work the banjo is by getting the fall right then shoveling the sand into the top hopper depending on how big you made the banjo you will need to pull the rocks out I do this with me shovel it saves bending your back.. a simple form of the banjo is one box on top of another.

This is what the banjo was based on, it was called a wet jigger and used back in the 1800’s there is a photo of one in a book called Gold Fossicking in Australia, and also in the 1934 miners guide put out by the NSW Mines Department which is no longer available.

For the Jetting pipes use 20 mm pipe, one 20 mm elbow one 20 mm T joint and two 20 mm end caps. For a one inch pump use 1.5 mm jet holes for a one and a half inch pump use 2 mm jetting holes.

As usual Spud you are making an incorrect and unfounded statement.
NONE of the information above Is or has ever been posted on the current Alluvial group's Yahoo pages. All files that do appear on our yahoo files page have been individually sourced by myself or compiled and edited by me and one or two others.
Considering the new Alluvial group was the migration of the old msn group and not a brand new group, the fact some information was copied across to the new proboards forums is logical and simply part of the move.

Remember...The msn site did not close, it migrated over to proboards!

well who could blame me for that association --
Panning - how do you do it
Jefgold as Stevo 444 suggested go to www.alluvialgprospectors.proboards.com they are a great bunch of blokes and gals that are more than willing to help you on any question about Alluvial prospecting. You will have to join first but that is only a formality. You can get plans from the site on how to build your own highbanker and sluice plus many more interesting topics regards to prospecting. The other site that Freshwater has suggested will not be much help to you because "membership is by invitation only". were the site I have suggested you can join on your own accored and will be more helpfull.

Charlie mate,
I use a floor mat with a smooth bottom which cost around $10 from Home Hardware or Bunnings. And the riffles sit around ½ inch high with a small lip at the top. See photo. Also take the time and have a read of the PDF file which link is below. It will explain all. Sorry I took some time in getting back to you I had a few computer problems. Cheers

Hi James ,
Just wondering what the measurements are for the skid plate ( L.W.H ). And the aprox angle for the hoppers .

Charlie the rule of thumb is for the skid plate to start at the rear of the top hopper underside ending a little under 4 inches from the top hoppers outlet. The skid plat at the rear of the top hopper needs to sit around ¼ inch off the hoppers floor. And around 2 inches at the out let end of the top hopper. That angles for the top hopper is made to be adjustable this is done so you get a choice when working different kinds of material as an example if you are working clay you will run the hopper flat but increase the angle as you move into sandy type of wash. On the bottom hopper the angle is governed by the size gold you are working the smaller the gold the less angle you work at about ½ inch to the foot is not a bad start. Sorry about the old style of measurement but it is easer for me to think that way. Grin cheers

Hi James ,
With the bottom hopper are the sides bent at 90 degree ?
And the top hopper is that about 65 degree ?
