Mine is rugged because I sandwich the whole screen between dimensional lumber. It's not just stapled in there or held on with a baton. This is important because the weight of a few shovels of dirt with rocks, coupled with the sifting motion is quite a load. It seems, looking at other designs, like the use would tear apart many other sifters.

bottom quadrant of the drum, meaning that only about 25% of trommel screen media performs work at any given time, while 75% is raised without material contact.
