I actually don't have an exact weight because I've been so busy between work and just CADing it... I didn't have the best practices so 1/2 the stuff is missing material properties. We made almost every practical effort to lighten it though; Each rail (inner and outer) is 3 +/- .05 lbs (keeps changing slightly with adding stuff), the wheels are .4.
for comparison, Last year's with a heavier frame came it at 50 lbs or so. I'll get a precise weight soon.
As for production,
-We have a jig setup to CNC the rails. They take about 2 hours to cut each (what I've heard, I didn't see them cut); During that time, we'll have kids on manual mills and lathes cutting the small parts out (most are really easy to make) and will probably finish within the day.
-The Wheels, Gearbox plates & shafts and the Frame will be cut/welded by our sponsor (NG), with a lead time of 2-3 days.
-All efforts were made to ease manufacturing time; off the shelf spacers, the wheels match the AM sprocket hole pattern so we just bolt them on, etc...
-We could spend two solid days in the machine shop and finish it; However, We'll probably wait until week 1.5-2 to make sure there aren't any drastic changes we want to make.
-Not counting of electronics, We could have one group assemble the modules, and another do the gearboxes and mate them at the end of the day.
Also, almost forgot this...

We hope to compete with it at the SCRRF Fall Classic on 9/29.
Any more comment/critisism is appreciated.
