Hi all. Hope everyone's doing well as we near the end of week two.
QUESTION 1 - Have any teams found a discrepancy between the actual weight of a goal your team constructed and the weight FIRST communicated - 181 LBS?
We constructed goals based on the BOM and updates, weighed each by hoisting onto an industrial scale, and we continually come up with between 130-135 lbs.
QUESTION 2 - If your goals do come close to 181 LBS, how did you weigh it? Are your materials the same as FIRST has specified on the prints?
Thanks in advance for the help!

We (Team 811, BG-MIT/LL) built the goal and ours came up to 172 pounds. i believe we built it exactly to specification, but I don't think we were dismayed by the fact that we were about 5% off the spec' weight.
We weighed our goal by hefting it up onto a spring scale hung from an I-BEAM in the ceiling. I am not sure how accurate these scales are, but this could have been the difference right there. (Actually, now that i think of it, we did not have the retroreflective tape....but that's probably negligable)
I think your 135 lbs sounds suspect (25% lighter than usfirst claimed)....if you built it to specs, you might want to look at your method of weighing it....perhaps do some "tests" by building a 50/50 sea-saw and placing various students and adults across from a goal to see which ballpark it really live in.. ..135 lbs or 181 lbs.
Good luck,
