Thanks for the tips Rob. I will be plugging the shop vac into the same electric point as the cabinet, so that the vac should be on all the time. I have a few dozen hours of cabinet blasting under my belt. When I was into designing and making parts for dot matrix printers, we were grit blasting up to 1200 parts a day, all for prototyping, tiny items that had been auto silver soldered together, and needed cleaning up afterwards. The problem was that we were using the finest grade of glass bead available, it was like talcum powder, and even when new, you could hardly see anything inside. But the worst was Arm & Hammer baking soda, that was so fine, it even got past the vac system seals and filters, and the whole place clouded up. Oh the joys of being in work. :bang: John, This is my compressor http://www.machinemart.co.uk/shop/product/details/sev11c-ol-air-compressor I'm not too worried about the pickup at all, even big commercial jobbies can suffer with that problem (most have a big hide hammer somewhere close to bang the cabinet to get the grit down to the bottom), it will only be used for small items that will be done and dusted in a couple of minutes. It's not as though I will be trying to clean up a car engine or wrought iron gates. Also, I am regulating the air input, hopefully, that will stop most of the problems scavenging the blast material, plus I will have more control of the surface finish, sometimes less is better. I will mainly be using my airbrush blaster in there, not the main gun, purely using the cabinet to stop the fine dust flying about everywhere. It just depends if I can operate the trigger with big thick gloves on. John |

I tend to use small glass bead, purely because it comes for free, and suits my style of effect that I want. For anything heavier, like Rob, I will use my pot blaster outside into a box, and the heavy stuff I use in that seems to appear as if by magic, also free as well. John |
