Compressing Shafts.

[stickbender]

     Yeah, El D, I think I will heat up the left over field peas, and maybe even make some corn bread to go with them, and have a beer, to kill off the damaged brain cells, that were actually trying to follow that stuff.  I didn't know "Werner (Verner) Von Braun" was into primitive archery......   See ya in the Ooga Booga section El D.

 I'm buying some tapered carbons from Chad at the Classic.

Boy, I'm sure glad I'm soooooooo simple minded  . ART

The compression block from 3rivers needs to be heated with a torch before used. Oogabooga mike =)

Well I have been spouting all this theory, what about someone with the block actually telling us what happens, there must be someone out there with one.

To those I have given headaches I apologise most profusely, I would recommend a few decent beers, (not of course that you yanks have any decent beers  .)

 Art, You know what I mean

I would really like to hear from anyone who has actually done this. I wont say you science guys are wrong but I just cant wrap my caveman brain around the theory that if you take X amount of material and compress it to a smaller diameter ,without removing any material ,that it can get weaker.

[jamie]

been done. you lose 5lbs of spine. block needs to be heated with a torch and then the shaft is pressed through with a drill.

[artcher1]

Learn it first hand from burnishing shafts and checking on my tester...........ART

[Justin Snyder]

Tested the idea on several types of wood. I was trying to understand the dynamics of bending wood, not building arrows.

[Diligence]

I wonder if an 11/32 shaft which has been reduced with the burnishing tool to 5/16 has a larger spine than a 5/16, non-burnished shaft?  (ie. measure of spine differences as a result of burnishing and compressing, rather than spine losses from the smaller diameter).

I would guess that the spine is higher for the burnished 5/16 shaft, as compared to the non-burnished 5/16 shaft. (of the same shaft material)

anybody?

Diligence,

Given the differences in spine between different pieces of wood I doubt that you could get a definitive answer to the question unless a large number of tests were done and you would have to start with pairs of 11/32 shafts of equal spine, reduce one by use of the swage, the other by say a plane. You would also have to prove that mereley reducing the diameter of a pair of shafts that began at the same spine produces smaller diameter shafts of the same spine.

 To keep it simple, thin bends easier than thick, Nootons Law of Compression.
