    Shaft Deflection or Squirt

    I'm a rock climber, and once upon a time, a long time ago, I got it into my head that I would design a lightweight tent. When I realized it would involve solving elastica equations I gave up. This guy discusses that very thing...

    So ESPN can't find time for pool?

    I've been thinking of giving up pool for cow chip throwing. I've been working on some low-deflection cow chips....

    what's the best cue you ever hit with, and why?

    That's the earliest I've heard of someone hollowing out a shaft. Do you remember the shaft diameter and the wall thickness?

    How low can deflection go and still be a useable shaft?

    David Alciatore did an experiment where he made a notched shaft to test this. I've forgotten where I saw it. Maybe he'll join in....

    How low can deflection go and still be a useable shaft?

    Let me repeat what I said earlier in this thread: "Sure, but look at the improvements in equipment in other activities that require accuracy: golf, shooting, etc. Those great players would've been happy to use today's best, most accurate gear, wouldn't they? They achieved greatness--not...

    How low can deflection go and still be a useable shaft?

    Let me repeat what I said in the first post of this thread: "It's the Indian, not the arrow". If Native Americans had had modern compound bows during the European invasion, the outcome might have been a little different. It's the Indian and the arrow. "All shafts deflect". True, but let's...
