Hank i wish had one to show you as it was only a suggestion to improvise. Like John said it is to stop cutting being sucked back up. We have a chap here in Swindon selling a lathe for £150 from his business workshop, sounds great till you see it. Its huge and would require a forklift to shift it and no room for that???? One place people forget for cheap secondhand are the papers like 'Loot'. Hope you find one for the right price.
