Re: Distal End Fails

It will be helpful if you describe more clearly the failure. Did the wood shear off from the glued surface? Did it break a distance from the joint? What kind of wood are you using? What are the dimensions? There are many many ways to make a good distal joint. You can see examples in the wiki picture...

Re: Lifespan of balsa and bass sticks

This is totally unscientific. I had a bunch of 1/8x1/8 sticks left over from last year. Every one was marked with weight and buckling load. They just sat in the kitchen counter behind the microwave for the whole year (don't ask me why). My house is always air conditioned and has no humidity issue. I...

Re: Which Mousetrap?

If you want to get the max out of the springs, bring a kitchen scale to the store if you have one. Invert the MT and hold it on top of the scale and let it press down. I have found that the Victor MT varies from 870 g to 1100 g, mostly between 950 to 1000 g. The difference is only about 10%. If you ...

Re: Remembering Len Joeris (Balsa Man)

I am really saddened by the loss. I would like to offer my deepest condolence to his family. The world has lost a kind, generous and passionate teacher and coach. I am a coach myself. Balsa Man has been inspiring me not only for his insights and passions for building towers, bridges, and boomilevers...

None of the trial events for B div makes the cut?? Trial events are usually for the next next (next) year of SO A trial event might not become official after one year possibly because there are already plenty of new events for the following season (so it is planned for later seasons) or it needs mo...

Re: 2015 National Tournament: University of Nebraska

I agree that the trial events were off the mark this year. The roller coaster was done in a small room. It was really crowded and limited to probably 15-20 people in the room watching. The event supervisor did the best they can to control the crowd and I think they did a great job given the situatio...

Re: 2015 National Tournament: University of Nebraska

The trial events are posted and the division B events are SumoBots, GPS, Roller Coaster and Sci Bowl. Sumo was a C division event in the past. I am wondering why they give it to B, especially given the limited time. Geocaching was a C event also. The rules still say it's C. Is it a mixup and suppose...
