That is quite the robust frame, weight?

[Seat Ninja]

Nice, now all you need is plate armor and a turret. Was welding the t-slot difficult?

[Zultraranger]

So what's the weight on that bad boy?

My guess is 22lbs for just the metal frame, but Ill wait to see what they weight it as.

Could be... or it could be a Railgun of DOOM. Depends on the team's preference.

I'd say around 30-40, but it has been a while since I was around that material. All that 80-20 will get really heavy.

I love the design of this. Very sturdy yet it has a slick feel and look. Even the welds turned out very clean. (from this distance)

I could be off, I just guessed some general dimensions and assumed .5lbs a foot. I think its like .51 pounds a foot. Since its welded you dont have all of those brackets whose weight adds up.

What about torsional rigidity from one 'front' wheel to the other? I am thinking the welding is a lot stiffer than conventional joining (screws) but I'd like to hear what you have found.

I would think so, but wowzers. It reminds me of our 2006 bot frame but wait, isn't this the 2006 game but with moving goals. JK

hmm, just curious... How do you plan to slide the little screw holders into the t slots?

Also, if you were goign to weld it like that, why not just use 1x1x1/8 aluminum square tubing?

1x1x1/8 aluminum weighs almost the same at the 10 series (1x1) 80/20, don't believe me? ask any of the kids on 73 from the 2007 season. I was skeptical also bu proven wrong.

As for the t-nuts, there are many styles of them, many can be inserted into the rails not from the end. 80/20 PN 3376 is one of them.

You cut slots and slide them in, but be sure that you dont make a slot where you need to mount something though.
