You could make a simple box out of plywood and cut two holes for long
vinyl heavy duty industrial type of gloves (cut a couple of plywood
rings and use screws to fasten the gloves to the box in case you ever
need to replace the gloves) for your hands and mount a piece of glass or
rigid plastic (check out some auto junk yards) on the front of the
plywood box and have your own sand blasting/bead blasting
cabinet.Perhaps add a hole on the rear of the box with a piece of
plastic or metal tubing and put the vacuum hose to an old vacuum cleaner
on the pipe.A rig like that,you would probally find handy to use many
times.
