sdsaw Posted July 20, 2009 Report Share Posted July 20, 2009 I see that the fluid bed (FB3) sold by Do-it and others has springs for it's feet. Do these FB's have a vibrating motor built into them? After trying several different filters to make my home built FB work correctly (coffee filter, brown and white lunch bag, 250 thread count pillow case, and vac cleaner bag) I've settled on using computer paper (The type that has holes along each edge) which has worked the best for me. I haven't used it very much yet, but the powder seems to settle and develop holes in it which lets the air pass without fluffing the powder. I have to constantly shake or stir the powder to keep it fluid. I've heard mention the use of vibrating devices to keep the powder agitated What are you guys using as a vibrator?
