By what percentage does tapering (11/32" to 5/16") a Douglas Fir wooden shaft, from the nock end only, affect the spine of an arrow and would these be as durable as non-tapered Douglas Fir shafts for roving and hunting?

Thanks.

very little but does decrease spine
  think about 1-2#
  but they straighten out from paradox faster

Thank you, James.

Any idea if they would be as durable as similarly spined non-tapered shafts?

I taper all my shafts.  The benefits are several, and I see no down side.  Shafts usually break at the pile end.  I've never had one break on the tapered nock end. 

The only person I've heard say they didn't like tapered shafts is Horace Ford.  He said he liked parallel shafts the best.

Depends upon how long the taper is. If 8-9” the effective loss of spine and grain weight is minimal, maybe 1# or so and 10-15 grains. If 11-12” taper then 2-3# spine loss and 20-25 grains. Also, it changes foc which is a more important reason to taper, IMO.

Thank you Steve and Kelly.

Reminds me I at least need to buy a grain scale.

Yup, I still use heavy points with a tapered shaft for even more foc. Use mostly 190 grain points.

Regarding tapered or parallel shafting I wouldn’t use any tapered unless they have at least a 12” taper on nock end, 14” is better yet. 😉

How much spine and weight you lose depends in part on the spine and weight you start with.  On relatively heavy POCs in the 60-70# spine range, I tend to lose about 2-3# in spine and about 20-25 grains in weight for an 8-9-inch nock end taper.  I expect Doug Firs, which are generally a bit physically heavier than POCs, would come in pretty close to that. Not really enough to worry about.  BTW, removing 20-25 grains from the nock end of the arrow only increases the FOC by about 1%; at least that's what I get on my 29-inch BOP arrows.

I should add that if you buy your shafts already tapered, they're spined and weighed after the tapering by the vendor so you just order the spine and weight you normally would.

Webster2, Kelly and Orion, thank you for your replies.

I only have experience with wood and aluminium shafts. Whilst I recognise the advantages of an aluminium shaft, it just feels cold and clinical compared to its wooden countrepart.

To date I have only used doug fir shafts from Surewood Shafts and I was hoping to try their tapered shafts but they only taper it by 9". So Kelly's post does put a spanner in the works. LOL.

Thanks once again for your replies. Will mull it over.

I think you will find the way Sherwood tapers their shaft there is no loss in spine. Their taper is parabolic not a straight taper, that gives you the good features of the taper without spine loss. I used a taper machine made by the same person for over 30 years.

Thank you, Bob.

It never occurred to me that the taper could also be parabolic.

I'll order a couple dozen shafts and see how it goes.

Thank you everyone for your insights on the subject. Much obliged.
