Replacement window for HF blasting cabinet

[5mall5nail5]

Hey guys I have a HF blasting cabinet:

http://www.harborfreight.com/40-lb-capacity-floor-blast-cabinet-93608.html

I screwed up and put a 12" incandescent light on the top to see a particularly hard part. It ended up cracking the window material. I cannot tell if its glass or plastic. Anyhow, is it possible to get a replacement window?

If it cracked from heat or impact, it is glass. See a local glass shop if HF does not have a good response.

Don't use cheap glass for this application. You want something that won't shatter and cut you. A glass shop should be able to suggest a proper type of replacement. I used laminated safety glass for the cabinet I built.

I went to a local glass company here in Vegas to get a replacement. It was 9 bucks for 2 tempered glass replacements. I'm sure that I will brake it before I use the second one..

High school shop has that problem. The kids seem to think it's funny to blast the window. Shop teacher just keeps replacing it with plexiglass. I'm taking the "adult ed" class there to get access to the tools, and the cabinet is pretty much locked during the day.

Do you think I could get plexiglass from Lowes for this instead of tempered? I think it needs to be drilled or something.

I have some polycabonite (lexan) here at the house
I also have some acrylic sheet material
if you give me the dimensions I could cut some and send it to you if you have a hard time locally
the problem with the plastic over the tempered glass is that is will etch quickly from the blast back or bounce
I used lexan in my cabinet and use a standard window screen and frame placed an inch away from the lexan to filter and deflect the bounce. I have had the same lexan window in mine now for about 14 years

I put a piece of thin acetate sheet that I got from a blueprint supply to protect the glass in my glass bead cabinet. That was in 1986, and it is still there! Of course, only a few trusted friends and I use the cabinet, but it is holding up very well.

It helps that the cabinet is 36" deep, so the bead is bouncing from pretty far away.
