Re: Hot Glue?

I wouldn't use hot glue. It tends to rip off the wood easily. Also, hot glue is much harder to get small amounts of, so the bridge is usually pretty heavy. If you want to use Gorilla Glue, then I would use paper weights, or pins on a foam board that hold the pieces together. Otherwise, like deholdgr...

Re: Geologic Mapping C

Does anyone know what map is going to be used for regionals and where to obtain them or examples of them. First of all, map types aren't specific to specific levels of competition—the same kinds of maps can be used at any level. One is a topographic map, which shows the elevations and contours of t...

Re: Designs B/C

I was just wondering how dense the wood was, because every time I used balsa wood for tension it broke. But now that I use bass wood, the tension members are much heavier.

Re: Designs B/C

Okay. I'll start building some "normal" bridges and see how they go. Also, what kind of tension members are you using? if you are running single tension members? So far I've been experimenting with 1/8x1/16 balsa and they seem to fail also a lot, way before the compression members' max load. Maybe ...
