Blast cabinets

that will work fine. you can even get away with the cheapo little gun with a 1 quart reservoir on the top if you don't intend to recycle the media and you can do your blasting outside. I'd strongly recommend getting a hood, though, if you do that. the media does get all over.
depending on the steel you use, it may even be advantageous not to recycle, as if you mix steels, blasting a stainless blade with media that's been used on low alloy stock will cause small bits of the low alloy to be imbedded in the stainless and you'll get rust specks.
 
Thanks -- what size of air compressor is recommended for one of these?

Don't worry so much about the horsepower(most manufacturers lie anyway), but get one with the CFM, at the pressure you will be using. That will usually mean 31/2 HP, on up, depending on the make.
I have a 31/2HP quincy, that flows more CFM than a so called 6HP CH.

You might want to change out the nozzle(probably 3/8") for a ceramic one, in 1/4". And if you plan to use glass beads, Aluminum Oxide, or sand, get at least a couple of packs of replacement window shields, advertized to the right of the blast cabinet. The mediums mentioned create a lot of dust, and will scratch the heck out of the inside of the window.
 
Great thread Michael. I've been wondering about later down the road getting a set up for blasting too. I've seen cabinets such as that at our local HF store.

Chisel/Joe has that one. He does like it compared to mine. It works well enough for knife work. The problem is the hopper isn't steep enough for the media to flow evenly. I also have a cheap HF, but it came with a stand.
