This is what I can't stand about the Internet. People can make up anything with no experience whatsoever and becoming an expert on nothing..

   A while back I purchased a dozen tapered Hex-shafts from Whispering Winds. Beautiful arrows that I cut the fletching off, put wraps on to accommodate anchoring to the nose . I was considering refinishing the shafts and adding new wraps as a project . Basically rebuild the arrow .
  The wraps that I did put on developed a small crease at the nock end .

  My intent was not to start any kind of a controversy, but see if someone had a solution ? I had thought of a couple of parallel cuts an inch long , at nock end might help ?

  Just so you know, there is a real good chance I won't get around to doing it anyway . If it ever warms up in Manitoba !!!

HEX shafts???

Really?

Bruce, are you actually intending to kill something or just dressing the part?

  Yes , Jim Jackson , every time I go hunting ,I intend on killing something .
How about you ?

   Terry , the hex-shafts , were made out of pine . Canadian made I might add .
I think Bob Barton used them a lot. It may have been 8 or 10 years ago when I got them ? I lose track of time .

[attachment=1,msg3027891]I remember the hex shafts.  Don't think they ever really caught on .  They took several pieces of flat stock and laminated up a piece of wood that had grains all opposing each other at around a 30 degree angle no......looking at the cross section now more like a 60?,  and then the dowel was milled from that.   They were after strength and stability if I remember correctly.  Well,  like I said......you never hear of them these days so they must not have been a hit,  but I do remember them.
The rest of all this thread seemed to have made it's way into the weeds.

I think this is a geometry problem involving two circles one of which has a diameter of 11/32 and the other a diameter of 5/16. The circumference of each one would be 2.15875 in and 1.9625 in. Those two dimensions would represent the ends of the wrap and they are parallel to each other and 8 in apart and you connect the two. Then cut it out. And wrap it.

Sounds like physics to me

Oops. I need to post a correction to the formula I used above. I used two pi d as the circumference formula of a circle instead of pi d. So divide the two numbers above in half to get the correct ones. My mistake.
