the rules say we need to know "history" for each specimen. What exactly does that mean? thanks!

Will the test be completely related to glaciers or do we need to know stuff like plate tectonics (as on the 2009 test)? Just wanted to make sure so I don't show up at regionals unprepared.

thats why you don't want wood with too many grains

please explain

what about zap a gap? is it better than epoxy?

If I have more than four members touching the testing surface on the base of a four sided tower, would each of the members have to bear less weight?

i don't know if this has been posted before, but i was wondering if the strength of a x-brace decreases if one member of the brace is bent over the other. I'm using 1/16th wood for the braces and i'm gluing at the endpoints and the piont where the members cross. I'll make a diagram when i can.

Does anybody know of a good place to buy 1/16 inch wood that is not online?

depends where you live and the shops close by
some stores may, just have to call or visit them

I live in chapel hill NC
I was wondering if there are any chains that carry 1/16th
