Here is the master tube bender, tool maker, and all around cool dude...Sandwich. Don't ever tell him he can't do something! Here he is testing out our really nasty 2D 2 inch bend tooling. The radius is really, really tight. It is the only radius that will work for our head tubes.

A little earlier, someone asked about Kirkham testing. We do testing all the time--usually to destruction
Here was one of my dumber ideas. We were going to make the threads on the hub out of aluminum to save weight on the hub.  (It is a LONG story, for another thread)
Anyway, no one thought it would hold and so we set up a test. I lathed an aluminum hub and screwed a wing-nut on it. We then tried to break it off in the press. Notice the I beams are bending

Here you can see the gauge reads 24 tons! Threads always amaze me with the amount of weight they can hold. Remember, the hub is hollow.
Anyway, I "Deep-Sixed" the idea after Thomas asked me how I was going to keep people from dinging the threads when they took the wheels off and on!
Ahhh, another "brilliant" idea on the ash heap of BAD ideas.
