Title: Skinny Shaft Question
Post by: 9 Shocks on January 10, 2018, 06:38:00 PM
Looking into changing my arrow set up a bit for next season.  

Currently shooting GT trad 3555's cut to 29" with a 50 grain insert and 175 grain head.

I'm looking to change to Easton axis trad 500's,

Does anyone notice if they act stiffer being that they are closer to center?

I'm going to bareshaft and tune like I normally do I'm just not sure what to expect.

I would like to shoot a 29" axis with a 75 grain insert and 175grain point.

I try to keep the orientation of my arrow shafts to the centerline of the bow the same for different arrow shafts. So if the inside edge of the arrow shaft is just outside the centerline of the bow for one arrow, and I switch to a skinnier arrow shaft, I will build out the strike plate until the inside edge of the skinny arrow is just outside the centerline of the bow too.  I think this helps to make arrow flight more consistent between arrows with different shaft widths.

The thing to avoid is having the centerline of the arrow shaft inside the centerline of the bow, which will probably result in poor arrow flight.  If that happens, you really should build out the strike plate.

What McDave says.  Bringing the shaft closer to the center of the bow, which is what a skinny shaft does, actually makes the shaft act weaker, or stated another way, enables the bow to handle a heavier spined shaft because it doesn't have to flex as much.  To make it act stiffer, you need to build out the side plate a little.

That being said, the difference may not be big enough to notice. The difference between 5/16 and 9/32 is 1/16 inch in diameter, i.e., 1/32 on a "side."  I  shoot GT 35/55s and Axis 500s out of the same bow without modifying the side plate.
