The lexan isn't likely to be used for the walls of a ramp..they are only 1/8". The side walls for 2003 were 3/4" I believe...perhaps 1". Either way, they were thick. Being a surface to see a FIRST logo under makes sense, and the traction on them isn't too terrible for FIRST bots (VEX bots are another story...we had lexan ramps in our Uber Tuber game and only 2-3 out of 21 teams could get up them).

The diamond plate is really driving me crazy.

Those 10' pieces of lumber could be used in conjuction with some of the 2x4s to make a ladder. For what...well...er..hmmmmmm.

Kev - who can't wait for the sound of a few thousand palms smacking a few thousan foreheads in just under 36 hours.

in '04 lexan was used on the top of the middle element and the steps were made out of diamond plate. arg this is hurting my brain!!!

Nope. HDPE (High Density PolyEthylene) was used on 2003's ramp as the top surface, 2004 had HDPE on top of its platforms, and the diamond plate was on the sides of said platforms.

What's really killing me is the sheer volume of lumber. I count three different types in two lengths, one of which (2*4*8ft) has a quantity of 17. And then you throw in three thicknesses of plywood. NO casters, PVC, flanges, magnets, or anything else that is unusual, except for the amount of wood.

Let's not forget that 2*whatever (usually 4) or plywood is a common substitute for diamond plate, depending on the application, but if there is diamond plate you have to maneuver on, forget it, you're better off with diamond plate.

Not quite. The small steps in front of the stationary goal in 2004 were diamond plate, if memory serves me right. (And even if they weren't, it was definitely aluminum.)

Everything else, though, seems accurate.

I don't want to sound like a smart butt but I don't understand your response. I don't know about you but I can rip a 10' 2x4 on my table saw into 2 10' lengths if I cut down the middle. I can cut at an angle and get anything in between (i.e. two 6' long 2x4s with pointed ends). I could even cut two 10' long triangle wedges if the 10' 2x4 was cut on a diagonal. I make no claims that anything I cut will be straight though. ;) My point is I'm not assuming anything about how we may or may not cutup and use any of the material on the list.

Polycarb - The see-through aspect is definitely important... I like the cylindrical idea... I think the Lexan will be rolled into a cylinder and will contain scoring objects, which must be retrieved from inside (?)
either that or maybe

Diamond plate - I think it will laminate over a ramp of some sort.

2x4s - There is just SO MUCH lumber, I have to agree: there will be some curved structure, sheeted w/ the luan, this will require ALOT of 2X4s for adequate support. perhaps even two angled ramps with a curved ramp in the center ?
Like this but of course less steep
/U\



Bolts, 1x3s and 1x5s - These have totally stumped me (esp. the 1X5X8!)

Maybe they weren't looking for super slippery; this year's game may be so devious that even a mildly slippery surface will give us enough trouble. :D

In 2004 the stairs were made of diamond plate, the intermediate platforms (red and blue) were HDPE and the top one (under the chin up bar) was polycarbonate. The FIRST logo was visible through it; that way you get slippery and purty, something the GDC really likes :yikes:

Ha. I wouldn't rule it out just yet. Who knows what's coming in the kit.

I was in the FIRST IRC chat just now, and there was this guy in there named sanddrag, and he made some predictions that sounded pretty good. ;) :D

Well, of course, but wouldn't it be a bit silly for FIRST to have us buy 2x4s only to make them into 2x2s? :p

I was just pointing out that you can't get two 5' 2x4s from a 10' 2x4, but even that's not true, apparently. As with their width and height, I'm told, 10' lumber is actually not 10'. It's a bit longer. Or so says the guy who works at Home Depot.

(This is why I hate lumber.)

Pipe is nearly as bad. One day they (yes, the mysterious "they") need to redo the naming/reference system on lumber and pipe.

...and heaven forbid that you confuse pipe and tubing. Oh man.

are you sure it's longer? i thought it was approx. 1/16th shorter because the mill has to cut it down so some of it becomes sawdust....not that it makes a huge difference... but it might to my engineer team membes :)

Very, Very difficult to roll a sheet of Lexan, even 1/8"
