help on glass thickens for a drop off tank !!

[simo2004]

Hi all not sure how much info is out there but i need some help on glass thickens for a drop off tank !!

i've built a few tanks in my time the biggest been 2.5 x 1 x 1m in 15mm

the L shape drop off is a new challenge tho mainly been the front and back panel

im told the tightest corner they can achieve is a rad of 8mm so that the front and back panne sit out side of the base glass not like conventional tanks

i've done the front and back in 19mm but im unsure if the sides need to be the same etc ?

Typically people calculate the thickness based on the longest length and height... and all front/side pieces use that calculated thickness..
This also ensures sufficient surface area for adhesion.

If your side pieces were thinner then the surface area for silicone would be smaller thus resulting in lower tensile/shear strength which could lead to the panels blowing out..

Thanks yea ive asked for quote in 19mm all round

i've just seen a tank will steel angle iron on the base to help with the pressures maybe ill look into that too !
