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
