Anybody shoot cedars with a 5/16 taper?If so what kind of weight are you getting from them?Any idea what the weight would be with a 60/65 spine?
I pretty muvh do it all at once and weigh and sort them when done. By the time my shafts are tapered they are also cut to 29 BOP and nock and point tapered. Cedar can vary a lot and not by spine either. Generally 360-410 is what I end up with.
I jsut made a doz 23/64 shafts tapered to 5/16, 31 inch long. I sanded them well and ended up with like 400-410 grains. Shafts were POC. After 6 coaqts of gasket laq, 3 five inch feathers and tip, they are like between 575 to 600 grains.
As stated above cedar comes in all different ranges in weight. I've had from 320 grains and up. The 23/64 will usually be a bit heavier unless the are compressed cedar shafts.
My 60-65 spine with 125 gr points and 30" BOP are usually from 540 to 575 grains when finished. I use both 23/64 and 11/32 tapered to 5/16.
I have actually weighed the shavings that came off the shaft after being tapered. 10-12g was the norm if I did not "go too deep. With a 10"taper on my 11/32" 65# cedars, that started 400g full length, I get a 515g arrow that is 28.75" and a 125g heads. 3 coats of laquer or poly is all I use.
Swampthing: I usually weigh my shafts before and after tapering as well. I usually get 15-20 grain reduction in 11/32 shafts with a 10-inch taper to 5/16. We're in the same ballpark. I maybe take mine down a fraction more.
3Feathers: as others have pointed out, you specify the physical weight you want when you order/buy the shafts. My numbers generally concur with Bjorn's. Full length 11/32 cedar shafts can run from about 350 grains to about 440 grains. I've had a few in the 460s and even one or two that were 500 grains. You can order from the low, mid or high end of that spectrum depending on the weight of the finished arrow you want. If you order them already tapered, you'll pay a little more but get the exact weight you want. If you plan to taper them yourself, plan to lose about 15-20 grains per shaft. Not enough to worry about, IMO.
