Re: pic: my version of a wooden chassis

You can easily remove material without compromising strength below a danger point. That 3/4 ply is heavy, too. Do you have a piece of 1/2" you can use? You really don't need that 3/4.

On the other hand, a cheap, strong chassis. Have fun!
total cost for the wood was $26.79 and most teams have should have everything else i used

Home-depot was out of 1/2 inch 1/4 sheets.......(would probobly save a pound or two without compromising strength)

thats really what i was going for with the wood,

its going to be 6wd if we have enough of the AM wheels left

it is really strong, i dropped it, kicked it, jumped on it , stood on it, and hit it with a hammer repetedly(and im not a small person) the only thing im concerned about is taking an hit on the side, and cracking the 2x6(but there will be bupers so it shouldent be that big of a problem)......


oh and interestingly, i think the bottom panel added a lot of stiffness, before i had it on, it would kinda flex out a litle bit
