Tapering nock end wood shafting

[bofish-IL]

Has anyone ever used 3 Rivers 10" Taper Plane Tapering Jig for tapering the nock end of wood shafts. Does it work well? Is that the only tool you need to get the job done. Also how much would it reduce the spine?
 
I need to reduce the spine on several hundred  old cedar shaft I have. Thought I might try this tool.   Thanks

I'm sure it works, Elmer, but I think you could do as well or better for less money with a belt sander.  On my ten inch taper with a 60 lb spine shaft I will lose about 2 lbs spine and 10 grains of weight.

How much spine are you looking to take off.  Roughly stated, sanding the ends removes more weight than spine; sanding the center removes more spine than weight.

It sounds like I need to try something else. I have picked up wood shafts over the years from several people and was told most were 60-65. I made one of the homemade spine testers and I have several hundred checking 75 to 85. That is way to heavy for what I shoot at 56 #.

Yeah, Elmer, that is a good bit of spine to remove.  I don't normally try to remove more than 5 lbs spine, but if you get into the middle of the shaft, it can come down pretty quick.  I'm looking to make a rig to do a much longer taper, like 24", and I think a ten pound drop would be realistic.  I have extended my regular 10" taper by hand and can drop the spine pretty good and the long taper makes a really nice shooting arrow.

I used to make a 10" taper with a small block plane and it worked very well.  It should work at 24", too and would definitely bring the spine down.

Have you confirmed the accuracy of you spine meter?  An XX75 2016 will spine at 59 lb.

You could also leave the shafts a little long or go up in point weight to make use of the stiffer shafts.

Tapering the rear end shouldn't change the spine by much if any but it will make your arrow more spine tolerant because of the extra clearance you get from a narrower tail. The spine of bought shafts is determined for an arrow cut to 28" with 125gr point on the business end. Anything over 28" will decrease the spine by 5# per inch. Adding more weight to the business end will further decrease the spine.
  I make cane and hardwood shoot arrows and that is how I was taught to treat the natural taper of these shafts.  Some of my arrows can spine out at 80# but shoot well from my 55#@ 26" draw and their 29" length.

Sounds from all this that you'd better re-check how your spine testing to make sure they're as stiff as you think!  

Once you confirm, there are the "woodie weights" that can give you higher FOC and lighten spine by front loading.
