I am wondering if anyone knows of an alternative window shield for a sand blast cabinet? I am referring to those little expensive plastic stick on sheets that you place on the inside of the viewing glass on your sand blast cabinet. Is there something else that I can use that will be less expensive - yeah, I know - I'm cheap.. or is there an affordable mail order source online? Those suckers are pricey and they don't last long. Any suggesttions will be greatly appreciated. Thanks. Gary
No you are not cheap, you're smart. Those replacement window covers are a rip-off because they know you can't get them anywhere else. I have had good luck using plastic cling food wrap and tape, it lasts about as long as the real thing and costs next to nothing even if it is a bit of a hassle to install. Not sure how long other people can get their covers to last but I went trough $25 dollars worth of them in less than a week!
The stuff I use is not particularly heavy but it is a commercial type food wrap I picked up at an "odds & ends" store here locally, I think Wall-Mart has some that another guy I know uses (I got the idea from him).
I work as in industrial mechanic in an aluminum foundry and I have 2 sand blast cabinets that are used to blast out cores to inspect the blades inside of torque converters.
I orders 2'x4' sheets of polycarbonate film from Mcmaster Carr. I can't remember the thickness off of the top of my head but I think its either .005" or .010", I can check for sure tomorrow.
Anyways look at item #'s 85585K72 @ $4.10 a sheet and 85585K73 @ 7.02 a sheet at www.mcmaster.com I order like 20 sheets at a time and tape about 5 together and cut them to size with a pair of scissor. The windows on our cyclone blasters are 12x24 so I can get 4 window films out of a sheet. I then just use some scotch tape to tape the plastic to the glass, but be sure that you tape all the way around it so sand/dust doesn't get between the plastic and glass.
I'd look for a roll of window film in the lightest possible "tint" and apply it. Another possibility is clear packing tape, 3M has some that's thicker than the cheap stuff.
Went to wally world and bought the house winterizing plastic sheeting kit. Cost about $3.00. I get several clear covers out of it. Works pretty good.
