Bamboo Shaft Diameters?

<< < (2/4) > >>

mullet:
 Those are probally Tonkin. I'd cut them 32 to 34" long and 8 to 10 mm thick. Then play with the spine from there.

PeteC:
Like the others said,there are a lot of differences between cane.Something I've been doing the last year or so is ,cut your cane long,like 4'-4 1/2'.After it is dry,Measure the deflection along the lenght until you find the desired spine.I have 2 nails driven into a shelf board,26" apart.Starting at one end,lay the cane on the nails,mark the location of the unflexed shaft,then hang a 2 pound weight from the center of the section your testing,mark the new location of the deflected shaft,then measure the distance the shaft deflected.Example:If the shaft deflects .45",then , 26 divided by .45 =57.78# of spine      or, if it deflects .3",then, 26 divided by .3 =86.67# of spine.   This is handy, because with this method you can rough test the spine before straightening the shafts.After testing a few of your batch,you will have a good idea what diameter you need to fit your need.Then cut, straighten,and build arrows.Hope this helps.  God Bless

Thanks for the advise guys.

PeteC, That is great formulae. How did you come up with that system? I think I like it better than my cabinet door spine tester.

El Destructo:
OK Pete....I really like the Formula there....now when you spine your cane...do you....and you set them up ...do you fletch them with the weak side of the Cane towards the Bow ...or away from it?? I know it makes a difference....but I cant remember which way to go...I believe it was weak side to Bow....but I am not for sure.........
