Hi Kevin,

I took your comment as a challenge, and looked on the Internet for
carbon tetrachloride. As you pointed out, it was difficult to find.

Then I took a more general approach and looked for acrylic
solvent. That hit the jackpot. There are zillions of products
around for repair and assembly of acrylic plastic - which is the
generic name for the trade name Plexiglas. Anyone who wants to fool
around with this material can find all the stuff he wants by
searching the net under the generic name. Solvents and repair kits
are not expensive and available from numerous sources.

Back when I was in A&P school, some 30 years ago, I was taught a
method of plexiglass repair using Carbon Tetrachloride as a solvent.
You can soak the edges of the break in it to soften the edges and
then press together until dry or you can dissolve plexi shavings in
it to make a glue which is then applied to the break and held in
place until dry. The break was then micro-meshed until the break was
clear again. There was usually a little distortion left but you had
to look hard to see it. Trouble is, I don't know if you can even get
Carbon Tet anymore. If I were trying to find it, I would probably
start at a drug store.

The solvent usually used to repair plexiglas is methylene chloride. This is the solvent used in many adhesives designed for acrylics. Liquid m c is very useful in repairing cracks in plexiglas. Ater stop drilling the crack, the solvent can be applied to the crack and it will wick in to seal it up. I used an insulin syringe for this. Any excess must be wiped up immediately.
