I picked up a KELCO blast cabinet in the local Bargain Hunter for $200. it is 5 feet wide and weighs about 1200 lbs.
I found out later it is worth a few thousand at least. It will hold a full motorcycle frame and it has a built in huge filter system with air powered filter shakers.
The downside is I need a bigger compressor - I have one thtat puts out 18 CFM a@ 90 and it is struggling..but with aluminum oxide it blasts like CRAZY.
Too bad I got to use boron carbide tips..$100US+ each..but apparently they will last quite a while.
It cleans up frame pieces beautifully.
