    Default Harbor Freight Blast Cabinet

    Does anybody have any experiance with the Harbor Freight Blast Cabinet P# 93608? I bought one today to use on AK (& a 1919A4 )rebuilds as the one at work that I have used for years is full of extremely corrosive stuff ( blasting some parts made them rust as if I put them in battery acid[ it reallly screwed up an AMMS build as it is rusting thru Moly coat on the top cover and underfolder stock]). I figure that the small amount of ocassional cleaning that I need to do will be fine with this unit. The blast gun is marginal, but should work. I will be using ground glass and blasting sand as a media. This hobby is getting really expensive.

    I'm not sure what part no. it is but I bought one of the free standing ones a couple of years ago and it does a good job. beats the heck out of doing it in the driveway!

    Got the same one and had to seal all the seams, but it works very well for what you pay for it.
    I also add a piece of pipe to the bottom pointing straight down and through the table it's on so it's easier to drain out if the media needs replaced.

    What are y'all using for blast media in the cab at work? Beach sand? Sounds like either the media has become contaminated and needs replacement and/or the compressor's air tank needs draining.

    While having a seperate cabinet for specific jobs has it's advantages, you'd also need a healthy compressor to run it.

    I was thinking the same thing, the media needs changed and the inside of the cabinat needs cleaned out also.
    If the compressor is used for multiple tools and has an oiler installed, the line for the cabinet needs to be placed before the oiler and a dryer installed before it goes into the cabinet.

    I'm just using glass bead that I got from HF, when I got the cabinet that's all they had in stock.

    im using the glass bead and alum oxide in a combo tht you can buy at the local Grainger.. its a 60/40 mix and does a great job of smothing and cutting all in one motion.

    oh and i clean all of my parts with purple stuff or simple green and brake cleaner before i put them in my cabinet....

    and yes i do run a vacuum system on my cabinet too, and while you go thru a bit more media this way, ive never had a contamination problem. so its worth it.

    I have had the same experience, the seals are really bad....what are you guys using to fix the leak issue....it also seems that mine doesn't release enough pressure so the top lifts up a bit, I might add a second filter on the other side to let more air out
