You are VERY lucky my friend. How long until your luck is scheduled to run out? Yeah, mine isnt very predictable either.
First of all, I don't believe in luck. Second of all, that will probably be a moot point once I explain what I believe to be a misunderstanding in my previous post.
Think about this: Just because you didnt need car insurance yesterday doesnt mean that you wont be involved in an accident tomorrow.
Read two posts up from this one. Are you going to just wait until your aquarium is on the floor in pieces before you decide that your stand needs to be upgraded? If you are immune to what happens to the rest of us, then dont bother.
Since written conversation tends to come across more aggressive and condescending then the author usually intends (which seems to be the case with my previous post also and for that I apologize), I'm going to give you the benefit of the doubt.
After reading my post, it seems I wasn't too clear on that particle board stand. It is no longer in use holding an aquarium. The plywood one I built replaced it. Though it was in use for some time, I did decide to replace it as it did look scary. However, it is still in use as a cheap shelf holding miscellaneous crap and it still hasn't failed.
My point was, even compared to how cheap store bought stands are made (and from my experience, actually work) I've never seen a DIY stand fail as they seem to always be overbuilt (which is a good thing). I never stated that one hasn't failed. I just haven't seen one that has, and seen many that haven't. Thus, the title caught me as amusing (not stupid, not misinformed, not mathematically unreasonable, just amusing) as it presumes that many do in fact fail. Now if I haven't seen any that fail due to my selective thread reading or not, I don't know.
The data and explanations that you present in your thread are obviously sound and will prove helpful to many I'm sure (including myself).
I am just an idiot anyway.

Anyway I hope that clears that up!
