Compressing Shafts.
CraigMBeckett:
El Destructo ,
The bending or buckling of a column is described mathematically as shown in
http://en.wikipedia.org/wiki/Buckling
Dy compressing the column you would make the moment of inertia smaller, see
http://en.wikipedia.org/wiki/Area_moment_of_inertia
Therefore you would reduce the spine.

I know that when you compress a Copper Wire for a Flaking Tool....It makes the Wire Stiffer...so I would figure that it would have the same effect on Wood....But If Science and Mathematics are against Me.... I stand Corrected......... :-X
Pappy:
WOW,I should have listened more in school, ,I would compress one and see for my self.
I would have thought it would have stiffened it. Not by reducing it,we all know that would make it lighter but compressing it I would think it would make it stiffer. ??? i will have to do my own
scientific study on that. ??? ;) ;D

I do it all the time with a screw driver. I haven't noticed much difference in spine. I do believe it strengthens the shaft. Jawge
jamie:
you'll lose 5lbs of spine. if you use 45-50's , compress a 50-55 and you'll have what you need. buddy used one a while back. not worth the effort in my opinion. if you are doing this for better penetration use a tapered shaft. they are easy to make . same rule applies to tapered shafts. go 5lbs heavier and after a 12" taper you'll get back down to your desired spine.
