so you think a 2x4 every 20" will be acceptable BL? Im going to frame my tank with 2x4s just like a house wall frame. but the studs will be every 12-14"s VS 16-18"
And it has Begun(muahahahaha)

I don't need an online calculator to tell me what I already know. I was referencing these for yours and other's sake.
And BTW, I'm NOT arguing that a braced over the top tank is stronger than non-braced...that's about as obvious as this argument. What you're suggesting is it doesn't matter if Andrew goes 10 feet or 20, he can use the same thickness glass as long as its braced on all four edges. I'm not going to argue further. You just go right ahead and keep thinking the sky is green.
You mean the sky isn't green?spiff;3209991; said:
Seriously there is no argument here, because it doesn't matter in the least if it's 20'... there are lots of tanks out there to prove this. Look around on MFK and I'm sure you'll find more than 1 which proves your theory wrong.
I am the first that would jump down Andrews throat if the this was a bad idea (I'm sure he will attest to this) but it's not and posses no problems what so ever. I would never agree if there was a risk to his baby... being a parent it makes me more cautious of such things and there just is not a problem with this type of construction

You're right, now I'm no longer arguing, its become a healthy debate. I do think there is merit to your idea's under certain circumstances, but that it has a deminishing return at some point. I feel that once you exceed a certain size in height for a given thickness of glass, then length will become a critical factor and has to be accounted for.
Maybe someone like Chompers could settle this.
Without a doubt your statement is true... but we all work with an average safty factor that is So high we wouldn't be able to reach a critical point without some serious flaws being made in the design and building of the structure itself or with having a low low grade of glass... like almost made it yourself low grade

That's pretty much where I have been coming from all along. Based on the ol' online calculators that show an ever increasing thickness based on length of glass used, and then they suggest the .50 for an 8ft span, I used deductive reasoning to conclude that he would want thicker to acheive the same safety factor for going 10ft.
It's not to say it wouldn't work. I wouldn't trust it though. I think when dealing with DIY, a smart person would err on the safe side. The slightest flaw on the window frame, and whatever safety margin goes right out the window. (pun intended)
Very true, and at first i was hella pissed but now i realize people are just looking out for my best interests. This tank will not begin untill the 15th of next month, and it will be a slow build. I will start another thread after that but I think the framing ideas i am starting to get are going to be awesome, extremely strong and just bad @$$ looking. I am thinking about useing 1/2" all thread( threaded rod ) alot the top,bottom and sides as bracing, instead of 2x4s on the top, it will be just as strong I think, 1/2" with a 1" washer bolted on each side causing posotive tension on both sides. and look industrialbasslover34;3210025; said:You mean the sky isn't green?

Unless your using Stainless (Super expensive most likly) it's not going to be worth it... since it's all going to rust to crap and be totally useless in the future, Just do it with some 2 X (insert your wish here) screwed in level with the top and it will have a "hidden" look which will give it a totally clean line if you don't have a top on it.AndrewMack;3210077; said:
Mock up your idea for the tank in Sketchup or something and get it posted up
The safty factor drop that the calculators are assuming isn't due to the length it's due to deflection.. which again we are able to eliminated with bracing the deflection that would still be present is going to gradually build but it would take several hundred if not thousands of feet before it would be something to considerspiff;3210075; said:
