I built this "enclosure" out of 2 X 4s and painters plastic tarp.
The idea was to contain the mess......then I crawled in there with the blast hose (suitibly protected) . It worked...too well....damn near choked to death.
Note to self....fresh air supply is a gud plan. Resperators don't cut it.
Then there was/is the sand that is almost completely shaken out of the nooks and crannies after bout 3 years.....and I thought I had em' all covered.
I used a fine grain sand #50, as I recall. It all worked out in the end, but what a PITA. Feel free not to use this idea
