Glass thickness--less than 3/8 but greater than 1/4
I used a sheet of glass (found by chance) 24"x60" and made a plywood tank out of it.
I have used the tank for fish for ten years without problem. Now for my peace of mind, I want to be sure that it is indeed 3/8". With the bottom wood frame the water height is close to 26" At the time I was aware it was thicker than 1/4 inch and thinner than 1/2 inch, I did not measure it. The top wood frame is too thick for me to measure the thickness. Any one here know the plate glass business very well? Did they make 5/16 glass plate about 15 years earlier? Is there a way to measure the thickness of the glass? I may cover up the top 3" with a sheet of nice looking hardwood and do not fill to the top, but hope not to have to do so.

It suddenly occurs to me that the bottom 2 inches of wood frame does not enter into the water pressure on the glass. I think I am right. So it is just 24".

Use the bottom end of a micrometer?
I'd say 10 years is pretty good peace of mind though.

The projected value of the livestock and the place (carpet vs tile floor) add to the concern. The problem is no reference point. The glass is seated on a rabbeted wood frame and the top wood frame is about three inches thick. I may use a C-clamp and count the number of turns in and out, with cushions of known thickness. I |
