Good design idea to use two pipe straps. I think a full pc.of dowel rod would be stronger. Better still would be 1" black water pipe. In H.S. we couldn't afford both Barbell plates and the bars so we used Black water pipe.
It's hard to tell if you used pine or oak dowel. Oak will give mote strength. Also consider the direction of the dowel wood grain in relate ship to the fulcrum point. Think about how & why a baseball cracks when it hits a baseball.
Interesting concept, the older I get the them more moving tanks becomes a real concern. Looking forward to see how this develops.

|GOJIRADOR||I extended the handles and set them on pedestals after which I placed 400 lbs on the board aaaaannnd nothing happened. I let it sit awhile and still nothing happened so I got on it my self and started jumping and still nothing. What I'm going to do is add a fail safe similar to what you were saying, lochabar. Just having long poles threaded through when I need them is arguably the smartest solution but I want the most bad ass so that simply wont do. The sleeve option was the original idea but I couldn't figure a practical locking mechanism with the materials and time that I had. Now I'm reconsidering it because I have a lot more time. Unfortunately it might be a while before I can post updates because there isn't any money in the aquarium account right now.|

Maybe you could stick a couple lengths of (sturdy) pipe on there, bolt that on with the brackets, and use that as sleeves for the extendable handles (I'd still want to use iron pipe for those, from what I've seen, wooden dowels (even thick ones) don't do so great with anything but compressive forces)
That might isolate (or at least reduce) the bracket screws from the lever-effect.
Think about using a claw hammer to rip out nails, It's not a huge lever, but you can still apply a lot of force, enough to rip out screws.

Nice job on the stand, but the handles looks like a really bad idea.... set up a small 10 Gallon while you are in school, if you really must have one. It will be easier to move around. Wait until you are done school and then set up the tank somewhere a little more permanent. Are you on a ground floor at school? Is there an elevator or stairs involved in moving the tank? Or are the moves on the same floor in a dorm?
Either way, good luck with the project, the stand is nice.

i think if you use this to transport a tank...
you're going to end...

|GraphicGr8s||Four of your brackets are taking all of the load. The outer brackets are only holding the rods in place. What you've created is a simple lever on the inner brackets and you're actually multiplying the forces there. You've got straight line force on wood fibers. Start sloshing water around added to your actually moving the tank and you're just asking for trouble. We're only trying to help you avoid a problem. Trust me, I've built a few things that sounded good, worked in theory, and actually worked great in practice. For a while. Fortunately those instances have been rare. Sort of. Last one was a lumber cart. Looked great though|

|GOJIRADOR||What I should say is thanks but it seems like I've left some details out of the description. They're not dry wall screws they're heavy duty wood screws that I bought seperately. There are Eight screws experiencing most of the load, I went to this website and calculated the weight of my tank at 1/3 volume which = 254.42 lbs / 8 screws = 31.8 lbs per screw, but they are not experiencing ALL the load because there is a second set of brackets that is accepting a smaller amount of force, even so 31.8 lbs is not enough in my mind to worry about. My research tells me that even at 70 lbs the wood is more likely to break than the screw is to rip out. My room mate and I have already tested our weight on it but I'll post a pic to provide some solid evidence|

|GraphicGr8s||Hoppy, take a gander again at the pictures. Do you see those pipe brackets through bolted? I sure didn't. Drywall screws at worst, wood screws at best. But wood screws nonetheless. In a straight line with the load. That won't pull out straight away now will it? (Rhetorical)|

|GraphicGr8s||Are you really going to try lifting a loaded tank up off the stand or is it to just move it on casters? OK just looked again. No casters. Do you think the wood screws (don't see any through bolts) will hold?|

I'm not quite sure what kind of cuts you're describing but oh well I've already got some doors on ha Definitely appreciate the advice on the paper towel holder it will be added to the design!
