Thread: Repost of fluid bed build

Thanks I wasnt shure if the filter media had to be strecthed tight to keep it from pushing up causeing uneven air flo.

capK - I was lucky a couple of folks here sent me some mesh and I glued mine in as I bought lots of top cups. If you're only using coffee filters or paper bags just get them tight and adjust your air flow little by little until the powder boils.

TJ's tackle Welcome to TJ's Tackle has the plastic type filters that you glue in the bottom of the cup but you'd need to check with him and attach a copy of the bottom of your cup to see if he has any that will fit.

If you run into any problems let us know and we'll get you through them.

Finally got off my duff and made a two cup fluid bed. Works much better than dipping in a jar of paint. the parts cost me about the same as one from TJS Tackle, but I know what went in to making it work. I decided to try coffee filters for now, put two on the bottom of the cup. first one glued to the bottom of the cup with silicon caulk, second one glued to the first with epoxy.
I used 2" PVC couplings for the base then cut 2 1/2" cups from a chunk of PVC pipe. For now I need to remove the powder after each use. Need to find some reasonably priced caps.

They aren't real hard to build, just make sure to let all the caulk dry real well, so you don't get any air leaks

Steve, check Lowes,HomeDepot. You are looking for a test cap. It will fit into the PVC with a lip to keep it from going all the way in.

Cray, my local home depot had few test caps that were all too small for the 2" pipe I used. they were about 1/8" undersized. must have got into the wrong box.

Was your pipe the thin wall pipe? If so that is the reason the test caps did not fit. I made up a dozen cups my self last week. But then again I had 20 that was in use. Most of mine are 3" and 4" cups. A few 2" but like the bigger ones my self.
Bought a big sheet of the membrane for the cups and will never go back to the filters again.

Where'd you pick up your sheet of membrane?? I kept shipping back and forth to McMaster Carr try to match the stuff that a member sent me.
