I have a small home-built blast cabinet that works well and that I'm
generally satisfied with. My biggest dissatisfaction is changing the
medium*. It's a PITA job getting the current medium out of all the corners
and edges, to avoid it getting mixed with its replacement. I'd like to
retrofit something to make it easier & faster. Especially to make it
faster.

Does anybody have a "system" for this?

An idea that I'm toying with is a liner that could just be lifted out with
all the medium inside. Just using a trash bag would be great, but it
needs to conform to the cabinet better than a bag would (specifically, in
the sump, so as to let the medium drop in). 6 mil polyethylene sheet
would be my first choice. This site uses a soldering iron to make seams
in it:

My hesitation would be over such a seam's strength. Anybody ever done it?

Also, the cabinet has a dust collector which keeps the cabinet at negative
air pressure. Meaning that any leak behind the liner would tend to
collapse it into the cabinet.

And, any holes in the liner would be a nuisance.

Maybe the liner isn't such a great idea.

Maybe I should just vacuum the medium out & collect it from the vac.

Ideas?

* - "media", "medium". The industry uses "media" whether they're talking
single or multiple. I was buying some locally and we were talking about
the different ones. I referred to a particular one, as in "... this
medium ..." and he corrected me: "it's 'media'". He's in the media
business, but he didn't know that the word is plural and that there is a
singular version. I let it go.
Bob,
I have a permanently hooked up blow gun in my cabinet blaster. After I dump
the contents I use the blow gun to clean out the nooks and crannies. Works
fairly well and fast.
