hahahahaha. im gonna avoid that

its only 7 ft long, kinda short but only place i can keep this guy is in the bed of my truck.

Planning on using HDPE for the surface

You want UHMW polyethylene not HDPE. Spread the word.

The one I built I used UHMW it came out real nice. Since it is only seven feet long you really do not need all of those supports across the middle. I would eliminate the support directly in the center which would reduce weight and save you some money.

k i think thats what ill do! i tried to do the stress test, couldnt make it work, it didnt have enough material data to run an analysis with pine. did find out that itll way 107.7 lbs tho! so that middle sections gotta go.

UHMW? first time ive heard of this. All ive heard of was high density poly ethylene. But whats UHMW and where can i get it!?

please tell me its cheaper than HDPE

HDPE is cheaper than UHMWPE and is commonly used simply because of the cost

oh ok. ill probly stick with the cheaper stuff, im really not even sure where to get HDPE in my area, so i might end up using some trex spaced out on the surface until i can get my hands on some. Anybody know of a plastic manufacturer i can go to somewhere in phoenix?

I find sheet aluminum is good. its cheap, easy to bend over corners, doesnt catch and is difficult to damage

It's way worse for your edges and just doesn't ride like plastic.

definitely overkill. get rid of the middle section and just have the upright supports at each 1/4 of the box and you'll be set. That's how i build my box and its taken quite the beating so far
