[QUOTE="Matt80, post: 369142, member: 3461"] Good question. Generally best not to have it at the very bottom, normally l would think a little above the bolt at the bottom closest to the chainsaw, but would need to make sure you didn't end up with a lot of dust being sucked in by the chainsaw. The material should come out just fine if you cut the exit in the flat plate close to the edge, it's getting spun around very quickly and the lighter dust will exit more freely than the heavier bits of rock so that's one reason the size of the exit mesh shouldn't matter as much. You will need to make sure you don't weaken the design too much by putting the exit in, but even if you go half way between the bolts closest to the chainsaw the material will likely exit just fine. One other thing that improves these things a huge amount and is really simple to do, make sure to put some type of gasket between the drum and the outer plate and compressible washers (rubber or cloth) between the bolts and the plate. Anything that will last and can be compressed will work as a gasket, but these things throw out a huge amount of dust from the tiniest gap so a tiny amount of money spent on a gasket(almost anything works) will cut the dust down a lot and the compressible washers on the bolts will cut down on the amount of time spent tightening them, the vibration will quickly shake it apart otherwise.
