Footed Wood arrow spine?

[steadman]

Got some arrows and shafts footed, but now they kkick (the arrows). Did the footing increase the spine? The foots(feet?) are 6" with a 4" splice. Thanks for any help.

I have next to zero experience with footed shafts, but wouldn't really expect it to increase spine much as the footing is on the end of the shaft.  I suspect that what you may be seeing is the increased forward weight has lowered the dynamic spine and now you are weak.  Try messing with point weight, up and down, and see if you can see some improvement.

Thanks, I'll try messing with point weights.

That's a fairly standard footing length, maybe a little shorter than some.  Regardless, footing does very little to the static or dynamic spine.  May increase the static spine by a pound or two, but no more.  And, they only increase arrow weight by 30 grains or so depending on length and material.  Remember, that there was cedar, or some other wood, there before, so you need to subtract the weight of the cedar removed from the weight of the hardwood that you replace it with to get the total weight added to the arrow.  30 grains on a wood arrow usually isn't enough to change its arrow flight much, if at all.

Check the footed areas for straightness.  Smetimes footings aren't put on straight.  In turn, the tapers aren't ground straight and the point is also put on crooked. Either of those can cause the arrow to act goofy.  It's also possible that the footings weren't sanded down to the exact diameter of the rest of the shaft.  Thus, at full draw, it has the effect of raising( or if sanded too much, lowering) the front of the arrow, messing up the relation of the arrow to the nock setting.  If that's the case, will need to raise or lower the nock a little.  Good luck.

Thanks for the info. The nock thing might be the ticket. But yea, they have increased the weight by about 40 gr total. I'll check fo rstraightness as well. Thanks.
