[QUOTE="Moneybox, post: 673612, member: 3960"] I was advised to go with a SS mesh, 125 micron from memory but it was a failure. It might have worked with constant air if there was enough airflow but it didn't work on my bellows machine. The mesh was too open and failed to keep pressure on the chamber below the riffles if some of the mesh was exposed. This meant that on startup and at the end of the batch the dirt didn't flow over the trays. I removed the very expensive SS mesh and replaced it with calico cloth and it works perfectly. My more experienced friend who recommended the SS mesh has since changed to calico as well. It eventually wears out but on a hobby machine it'll last a very long time. [/QUOTE]
