Looking like it should work ok mate. I would be putting some long bars, wood or dowel down the length of the trommel on the inside, about 3 or 4 will do. They will help circulate the material and also strengthen the trommel. Keep in mind with the 1/4 mesh, you will need to classify material before putting it in as it wont be able to handle many heavy large rocks. I use a 1" mesh on the inside of my 1/4" mesh to throw out the larger rocks first, multi-stage trommel.
So with sum playing around and a 4 step possess to upload a photo I think I'm finished with the build.
Don't know if I'm going to glue it together or leave it? If I don't glue it, I can pull it apart and fit it it into the main trommel for easy transport?? :|
I think I'm going to glue strategic points, mainly the body and leave the legs this way I can adjust the hight by simply turning the front legs, I can the put the legs inside the trommel and with a shoulder strap I can hike it in anywhere.
If you run the offset on the drive internals at halfway and just a little in from the overburden outlet you can get a steady bar in from the feed end from a third to nearly halfway. Halfway for the internals is about the maximum before you get too much wobble throwing the centrifugal action to an elliptical action due to load. I've seen them set up using the internal drive shaft as the spray bar using a tap connection. Good luck mate given enough thought a Centre drive trommel can have a decent set of spray bars, take it from me you will need to include shielding if putting water in around the classification section of the barrel or throw water all over the place haha.
