A guy i know has one made from a old small refrigarator.used the wire shelves to set pieces to be blasted on,easy access via full door
in front.just cut center area however much you want and put plexa glass see thru in it.old crisper trys catch most the sand.tho i think a funnel bottom back to a hopper would be better,oh,he has a flood light mounted in top to be able to see.Also i used to work at a monument place and i
had a brass mesh screen over my view window,it kept window from being ruined,lasted a long time,tho i dont know where it is available,just a few more ideas.BTW i blasted with 120 lbs air 1 inch hose with 1/4 inch nossle opening,and used alumium oxide adbrasive,now thats fun to blast with.by the way he just had a rectangle opening to blast thru as did we were i worked,just use a strip of old rubber inner tube with two holes cut in it for your hands in a X shape ----> [ x x ] this works ok as it is what i used where i worked,and the blaster i used could cut a 4 inch hole thru
solid granite monuments in minutes and never worry about sand hitting anything rubber,it wont hurt it,fact we used a rubber glue on sheet to protect
stones that was only a little over 1/16 inch thick,just bounces off of rubber, rubber gloves as well...i have saw a lot of diffiuclty with home systems due to dampness clogging,sand must be kept real dry.Along with dry air supply.And if you want to do things like pintons,use glass beads and not sand.I know they are best but
i dont know where you can get them. Also if you are going into a decent setup,a cabinet exaust fan is well worth having{exausted to outside) .And use like a 250 watt
flood lamp,it will eventually frost,but that wont hurt it.front glass is thick. Use a piece of window screen to filter used sand back to hopper.And most
of all,NEVER EVER go near it without eye protection,tight fitting goggles are best,they leave no where for that stray grain of sand to enter.And
from years of blasting,even in a factory enviroment,never take goggles off till you use the air hose and blow all sand and dust off of you,from top
of head down,i assure you its cheaper(doc i got sand in my eye!! doc? where are you doc? i cant see you!) and less painless than sand in your eye hours later that just happened to be hiding and waiting in your hair,etc.
