Quote from: Burnsie on December 22, 2025, 11:08:22 AMThe Oak Creek link works for me. Whether you can still order from them is questionable, but I can click on all the buttons on the web site and see the deflection charts, explanation of formulas...etc.

  Burnsie, thank you for that information! I gave my computer a mighty crack and all is good now. The link works.

Kelly, yes, I'm well aware of Easton's 'snafu' regarding the 1.84 pounds (more correctly, it's 1.94 pounds). Bob Burton has explained it to death. Er, I'm not sure what all that has to do with my message I posted before...

Yes, deflection is deflection, be it wood or other. Easton's method and the ATA (old AMO) method are translatable using the .825 factor, and it is explained in the following link. Please give it a careful reading.

This is an excellent reference from Oak Creek. Thank you for sharing this.

What it all means York is his scale is wrong. 50# woods should be .520 deflection and his scale is not even close to that!

I've been using a Scheib spine testor for almost 60 years so I know some about this subject. Yes 1.94# is the weight of Easton used on their Scheib spine testor.
