Like Eric, about 35 years ago I built one of the TP Tools blasting cabinet
kits made from 3/4" plywood and it's been working great all these years.
At the same time I also bought their vacuum kit and built a dedicated
vacuum from two 30 gallon drums. The vacuum motor lasted all these years
but finally gave up the ghost this summer so I bought their replacement
motor and all is well again. I've probably replaced the window glass a
dozen times over the years.
Mine is free standing and always ready to use. It is used frequently and
every time I use it I'm reminded of the reason I originally built it, the
restoration of a 63 spitfire :)
I don't know what I'd do without it.
Brad
Merry Christmas everyone :)
