Re: **FIRST EMAIL**/Advance Materials List and Autodesk Virtual Kit of Parts Informat

maybe lavery and the GDC are enforcing the rule of no fasteners even upon themselves

btw, Luan is a Moisture resistant plywood generally used as an underlayment between flooring and a subfloor in damp places. Yes, working in Lumber at the Home Depot has taught me a few things, like Luan is very flexible like can be used to make mailboxes....

Of course, the double asterisk indicates that teams can substitute something else... I'm wondering if they're responding to complaints about the advance BOM being the low-cost version of the field, when some teams would prefer to build the real thing.

Hmm, well the parathases didn't work it right, but it would be more like a quarter pipe on either side of a flat platform.
Lauan is know for being a very light type of wood, which is very easy to bend and shape. We've used the stuff to make light, easy to move walls for stage productions at school. I can't wait to see what the Lauan and diamond plate will be used for.

Happy Kickoff!

Re: **FIRST EMAIL**/Advance Materials List and Autodesk Virtual Kit of Parts Information

WOW!

This looks like building material for a house!!!!!!!

I can build a 10-ft wall and several platforms and ramp.

(remember- this is just the Team (home) version of the field competitions. There maybe several 10-ft walls at the real field).

Re: **FIRST EMAIL**/Advance Materials List and Autodesk Virtual Kit of Parts Information

I think the carriage bolts are used to hold 2 of the 2" lumber together, it would be hard to tighten the carriage bolts if they were used to hold the tread AL down, unless you can make a square hole, but at 4" long, 2 pieces of 2 " lumber would be 3" to 3.5" wide plenty of space for a washer and nut under the head, also in 2004 the uprights that held the bar were held on with similar types of bolts, in an application like that screws are normally not enough.

Just as an aside to the AL tread plate, to cut something that big you could use a jig saw with a metal cutting blade and plenty of lubricant(wd-40) we did this to make our crate from that material.

All I can say to that is OMG. They need to fire those idiots. If someone doesn't know what a carriage bolt is, they have no business working in a hardware store IMHO. You'd think they'd at least make them take a basic hardware knowledge test before hiring them to work in a hardware store. I once encountered an employee in the plumbing department of my LHS who didn't know what a PVC pipe cap was. As a person who visits a hardware multiple times each week, it is sad to see the quality of service degrading faster than a, uh, oh um, landslide.

Re: **FIRST EMAIL**/Advance Materials List and Autodesk Virtual Kit of Parts Informat

what if it is a triangular platform with ramps coming off of the three sides. some kind of goal/bar would be above the platform.
two of the ramps' plywood would be covered with lexan (4'x8'), the third ramp covered with aluminum tread(4'x8').
this idea could be modified for a truncated pyramid also.
2 ramps would be lexan coated, another would be aluminum tread, and the 4th be just plywood...

Just so everyone knows, the 3003 refers to the Alluminum Alloy (commonly called Bright Aluminum), the H22 and H24 is the Temper (heat treatment technique) and the TP refers to the Tread Plate (offical name for diamond plate)

yeah to verify that some more, http://www.astecuk.com/aluminium_rolled_prod.html
lists their DIAMONDBITE TREADPLATE ALLOY 3003-H22 to be like



however, http://fzxrangxrn.en.alibaba.com/product/50100143/50446835/Aluminum_Tread_Plate_Coil/Aluminum_Tread_Plate___Coil.html
lists their 3003 H24 to be like


so does the manufacturer change what kind of treads the tread plate has? The two options you see here are Diamond or Quintet (5-Bar) patterns

Re: **FIRST EMAIL**/Advance Materials List and Autodesk Virtual Kit of Parts Informat

Lauan is a cheaper alternative to standard plywood, and you need 2 sheets of quarter inch thick 4x8' of either material.

My guess: These 2 sheets will not be driven on, or have enough support under them from the 16 million 2x4's in the BOM so that the strength of the material won't hamper its ability to be driven on by 130 lb robots.

Therefore, teams can 'cheap' out and save a few bucks by going with lauan. This fields going be expensive enough, and I think FIRST is trying to cut us as many breaks as possible.

so does the manufacturer change what kind of treads the tread plate has? Hmm
Typically, I believe the upper one is just called "diamond plate" and the lower one is called "5 bar tread plate" (no reference to diamonds) I'm guessing it is the upper one. Those are the two most common styles and probably the only two carried by Home Depot. Any other styles are probably not it. I'm no even sure if Home Depot carries the 5 bar. I'm thinking is will be just your standard diamond plate.

Could that be tread plate, as in the more accepted name of diamond plate, or tread plate saying theres a Quintet (5-Bar) Tread pattern. Instead of a Diamond Pattern, or is (Diamond Plate) refering to the tread pattern? This may have to go to the Q and A

Or wait about 31h 10m give or take a few and see it during the kick-off then by the material that would be quicker.
