Improved, Spine-O-Meter Mark II

[Old York]

The 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.
