Guss,
I agree with LBR. I used to buy cedar shafting by the 100's. You'd be amazed the variation of spines you'd get in 100 shafts! 35-40#, 40-45#, 45-50#, 50-55# would all be in one bundle after I ran thru thru my Adam's Spine Tester (not a cheap tool in itself either).

No one shoots wood arrows because they are cheaper. They shoot them because they LIKE wood.

If I factored all the work, materials, etc. (which was a labor of love - for me anyway) it'd probably been cheaper for me just to buy Easton Game Getter arrows and be done with it.
You figure you need a spine tester, taper tool, stain, shaft clear coat, cresting tools, paint and brushes (if you get into doing that on your arrows as well), etc. The investment of tools alone will cost ya a bit of cash.

Wood shafts require more work in inspecting them after an outing for damage. You also have to keep an eye on them to keep them straight.

G. Fred Asbell said right in his own book that making wood arrows usually doesn't save the builder A LOT of money. Its usually done because people LIKE making their own stuff, want a winter project to work on, etc.

Hope this helps.

PS FS Archery in Calif sellsPort Orford cedar shafts at decent prices. PS 100 cedar shafts now cost $144/8 dz- thats $1.44 ea. Not cheap these days.
