Ron,

Modern home aquariums are not held together with
anything other than butt-joints held with silicone. 
The plastic "frames" are not structural. 

I have a 75 gal tank in my living room which is
incredibly heavy when full, silicone is indeed sticky
stuff.  If you look at a large home aquarium, the
frame is often just mitered at the corners and each
frame-piece is glued to the glass, presumably after
the tank is assembled.  There is undoubtedly alot of
shear present in the corner joints.

I'm a big fan of your "tutorial" posts,  you're slowly
building my resolve to bite the bullet and buy an old
lathe.
