Plywood tank question?

[chriswf]

Okay, these are my "blue" prints.

Pond armor has already been ordered.

The tanks dimensions are 40height x 40 width x 40 long.
My glass is 32x44". 3/8" or 10MM wide/thick.

Is my glass going to be fine?

2 things I'd like to mention:

** I do want exterior support. JUST in case. For overkill I guess.
Maybe not THIS MANY 2x4s, but I want some. Remember the tank is 40" wide, so those 3 2x4s on the sides will be spaced out a bunch.
Maybe even 2x4s connecting horizontally to the 2x4s running parallel across the back.
Too much?

** And my glass is starting 6" above the base of the tank, right? Or does it "start" on the inside where it overlaps?
I was suggested by someone - that this may help with support and pressure at the base.
Each grid square is a 2x2 inch.

Here's some blue prints laid out:



Also, I'll EVENTUALLY cover the exterior with some kind of wood. Maybe wood flooring and stair-noses on the corners.
Insulation in between the exterior and interior wood because -

THIS IS going into a GARAGE!
Hur hur. I already have some of that bubble wrap insulation and pink insulation. I currently use the bubble wrap insulation on my glass tanks - even inside my house. (I used to breed convicts to feed to my Doviis).

Here's the tank I'm getting my glass from:


So do you think the glass will be okay?
Was hoping to have finished my wood framing today or yesterday - but couldn't get any solid info on the glass thickness.

When I researched building one it was the height of the tank that was the determining factor on glass thickness...... Imo it sounds like 3/8" is a bit thin for a tank 40" tall.....
I will try to find the chart I used and post a link

[stealthy hunter]

I thought I was correct.... just remember that it is the height of the tank not the glass that will determine the glass thickness. From the chart you can see a min of 16mm and recommended 20mm for a 36" tank and yours will be 40". So I would be very careful

Btw.... .the number below the glass thickness is the safety factor.

I really hope this info helps you out....and good luck on your project. I hope to see some pics of the build.....

I am really kinda jealous I have always wanted to build a "big ole" plywood tank.......

good chart above. 3/8" is definitely too thin.
