For normal work in the studio when ABing cleaning pot is a must. I wanted to buy factory made for several times I was at our airbrush supplies importer office, but the size of the filter stopped me When I'm in the shop malls, I always watch around to find smth useful for ABing. So, once being to kitchen dept, I've found interesting pot and an idea strikes me there Not to speak long, here's how my idea's come true: Random pot and AB Cleaning pot To make this you need: Dremel tool with diamond bit (straight shape) Pot Electric cable seal Used charcoal filter cartridges from the respirator Caution! Be extremely careful when cutting the hole for the insert! Keep the tool straight! Wear safety goggles!!! There are several sizes of the cable sealers, so chose one to fit your AB dimensions. Cable sealer allows to make the hole for AB head of different diameter by only screwing in/out it: ... and to fit any airbrush: So, in the end we have good working result for ridiculous price, but what's the most important for me, with huge size of the filter, compared to those installed in factory made AB cleaning pots. I've worked with similar and it works great. To be continued.
