I recently scored a new weapon to add to my arsenal of workshop equipment in the shape of this funky Clemco blasting cabinet. I’ve been looking at getting some kind of blasting cabinet for a while, but it seemed that to usual DIY ones didn’t seem to offer much for the money. This used Clemco one is a proper industrial unit and was considerably cheaper than a new DIY type unit, so I jumped at the chance when it came up for grabs. This is still a vacuum fed system like DIY cabinets but has a benefit of a full extraction system to draw out dust and debris from the media. It’s largely made of some kind of blow moulded plastic (ABS maybe?) and has a drawer at the bottom to collect dust which doubles as a dead mans switch to control the air supply to the gun (you just press your toe against it). I’m not sure what the round black knob on the front does yet, but the rest of it is pretty self explanatory. The window into the cabinet seems to have had some thought put into it as it’s a curved, horizontal affair, designed to prevent to media from hitting it and etching the plastic.
I wasn’t too sure if my 16CFM single phase compressor would have enough capacity to power this, but it seems to do just fine. The flow of blasting media is constant and it seems to do the job pretty well. The cabinet is just about big enough to get wheels in, so it should be capable of doing all I need it to do, although it could do with better internal lighting as it’s a bit dim. So far I’ve only run it with Aluminium Oxide abrasive but I’m going to give it a go with glass beads and see how it does.
