Carbons and bare shaft tuning
 

Since I had some shafts with vanes I want to refletch with feathers, I tried something.

Shafts are CE terminators (black) 45-60, 29" long nock to insert and have a 125 grain tip screwed in. I was sure they were flying well, didn't seem to be doing much in flight and I was pretty happy with my shooting results.

Enter the bare shaft. I stripped one of vanes, turned my box target around to the unused side, backed up to 10 yards, took aim and let fly. Nock point seems to be correct, but the nock end of the shaft was to the right in the target. I repeated this several more times, with the same result.

This indicates shafts are too stiff, right? 125 grain is the heaviest tip I have on hand. How much heavier might I need to go to bring the nock end back in line in the target?

You're sure you were shooting square on to the target, and not off at a bit of an angle, I assume.;)

Yeah, stiff arrows stick nock right for a right handed shooter. But I'd be more interested in seeing how a bare shaft groups with fletched shafts rather than just going by that. Sometimes the target itself can kick an arrow off on an angle when it sticks.

:D

I was just reading something similar at OL's site.

I'll try it this afternoon, if possible.

Got a chance to fling several.

Bare shafts definitely impact left of fletched shafts. From 10 yards, about 3-4" left.

How much heavier in point weight do you think I'll have to go up from my 125s to get the right spine?

For the record, CE terminator at 29" nock to insert with 125 grain tips from a Martin X-200 recurve 45# at 28" drawn to 28"...

Just make them longer [:-]

No can do. Arrows were bought cut and inserts installed.

I have no problem with using a heavier head. Just would love to get an idea how much heavier to avoid the trial and error expense.

Someone talk me down.

I was thinking about this last night, and why couldn't I get a bolt that would fit the tip adapter and several washers and a few nuts and play around with different weights that way?

Anyone ever done this?

I tried shooting some wally world special 29" 45/60 terminators from a 49@ 27" black widow psav.I found that even with 175 grains they were too stiff.I figured I would need at least a 50 grain weighted insert and a 175-200 grain head to get em right.You could get some brass washers and just add them behind the fp see what happens.

Gold tip makes an internal weight system. 3 rivers also sells internal weight systems.
