All of the modifications above are out of necessity for the HF blast cabinet. It's a good product for the money, but I must say that I am sick of that POS after owning it for the last 22 years. Constantly servicing and repairing it is a headache, and the dust... oh, the dust. I've set aside a fresh piggy bank for a wet (slurry) blast system after checking out several of them at work. There are a couple of good ones appropriate for the home shop that are turn-key for under $3k, which at this point is totally justifiable for me (and I'm a bit of a tightwad). I get so much use out of blasting and parts washing. I'm also conscious of the lead, chromium, and nickel in the coatings and substrates that I don't want to inhale any more of that dust every time I walk past the cabinet. Just thought I'd add the wet method to the conversation, it's very attainable and also a good candidate for a DIY project or modification to an existing cabinet.
