Default Plywood - 3/4 vs 2 Pieces of 1/2"

Are 2 pieces of 1/2" BC grade that I glue as strong as factory glued 3/4? Thanks!!

I can't see why it wouldn't be as strong. What type of glue and how did you glue it? Did you clamp it? What do you plan to use it for that you are concerned about the strength?

Aquarium stand 30 x 18 with a cross bar in the middle. I need two 3/4 shelves; have one but also have 2 pieces of 1/2 BC I could use. Glue, screw and clamp.

I think that will be plenty strong enough. If it is just a shelf beneath the tank, I would probably just go with 1/2" if you aren't going to put anything super heavy on it.

From what I have heard, the two glued together should be stronger. Alternate the end grains (sheet A end grain on top and bottom, sheet B end grain left and right).

That is the proper way and coat each side with 2 part epoxy then make a frame with 2x4 and clamp it over the plywood to equally distribute the clamping pressure until it dries

X2.

Just lay them on a flat surface use good wood glue or epoxy. The plywood you have is just ~1/8" pieces glued together to make different sizes.
