BobFuller Posted May 18, 2012 Report Share Posted May 18, 2012 I've been having a terrible time with the vulcanoes myself. I have about 120 different colors, and it seems that some colors work better in the bed than others. Do the fluid beds you buy get these vulcanoes as well? I'm almost thinking that if you were to use a smaller diameter PVC fitting, maybe 1.5" rather than 2 it would work better? Air is going to take the path of least resistance through a coffee filter, so if it has less opportunity to stray and force itself through the easy spots, maybe it would work better?

Jig Man Posted May 18, 2012 Report Share Posted May 18, 2012 Don't you have a valve that you can use to adjust the air flow? Have you tried something else for filters like brown grocery bags? Quote Link to comment Share on other sites More sharing options...
BobFuller Posted May 18, 2012 Author Report Share Posted May 18, 2012 No I didn't try brown bags, I have a valve to control the flow, but still get them.... I'll try the brown bag! Quote Link to comment Share on other sites More sharing options...
Jig Man Posted May 19, 2012 Report Share Posted May 19, 2012 I use vac filters, coffee filters and brown bags. I find different mediums work on different colors. Quote Link to comment Share on other sites More sharing options...
BobFuller Posted May 20, 2012 Author Report Share Posted May 20, 2012 The vac filter sounds like a winner! I have plenty of them laying around too! Thanks for that one!! Quote Link to comment Share on other sites More sharing options...
saskcat420 Posted July 5, 2012 Report Share Posted July 5, 2012 I also have the same problem. I use the brown paper bags. Some paints work really well and some have terrible volcanoes. Some seem more dense . Quote Link to comment Share on other sites More sharing options...
BlueCHip Posted January 3, 2014 Report Share Posted January 3, 2014 I use printer paper and it works great. Quote Link to comment Share on other sites More sharing options...
gone2long Posted January 3, 2014 Report Share Posted January 3, 2014 Notes, notes, notes, the pigment sizes are different on certain colors so check to see what works and make a note of it as that is what you'll need to use more often than not for that particular color. Kinda likening it to the way airbrushes have different paint reductions or PSI for different colors in the same paint line. Quote Link to comment Share on other sites More sharing options...
