No - either method will result in a rougher, sharp edge. You can knock it down with aluminum oxide sandpaper, just be careful.Its a 55 gallon display tank.
I think if I would cut a piece of glass to put under the brace and either bond it withe silicone or epoxy it would help reduce the pressure on the original brace. Then even a weak bond would keep the center brace in place and make it look presentable.
My question is if I cut glass with a glass cutter or the twine and fire method would it create a clean break that doesn't need sanding?
I am from the school of "better safe than sorry." I did my patch job today. I have 4 pieces of plastic in total. not only is the piece inside the hollow, but there is a plastic strip on top of that raised part of the brace and then there is one strip under each of the flat protrustions on which the lids rest. It is now solid as a rock. I did not drip any of the glue or anything else into the protective plastic box I managed to slide under the work. After using the clamp to rejoin the brace halves where it broke, I let it dry for 30 minutes, Next a plastic strip was glued to the top across the split site and it was then allowed to dry. Each strip applied to the underneath was done one at a time and allowed to dry. The hardest part of all this was finding things I could slice up with which to make the"patches."Re: Galvanized metal in tank?

I work in the steel industry...
Usually, if metal is galvanized, it tends to be galvanized mild steel.
The mild steel is bathed in highly concentrated Hydrochloric acid, then cleaned, then bathed in molten zinc.
When the steel is removed from the bath of zinc, the zinc cools and hardens and then the steel is known a galvanized.
The zinc itself will rust, but will take a VERY long time to do so even when submerged in water for a long period of time, BUT, the zinc (depending on the quality of the galv process and purity of the zinc) will probably start to flake off when submerged for a much shorter period of time, and mild steel will rust in a matter of hours leeching chemicals into you water...
So really I would avoid galved anything in a fish tank, and lean towards plastic, silicone or maybe stainless steel.
