#80 shafts for 57lbs bow?
« on: July 08, 2008, 03:17:03 pm »
I switched from Olympic recurve to laminated flatbow 5 years ago and than to hunting recurve. last year  Now I shoot  #57@29” Bear Grizzly  with 55-75 GT and 400 Beman shafts  29¼” with 100 grain tips and short 21/2-3” feathers. I also enjoy making wood arrows, cedar, spruce and fir being my favorites. Having made over 100 of them all with nice egzotic wood  and horn nocks and all very straight I decided to give them a try. I started shooting them for good lately but I’m not totally happy with them; majority of my woodies are spined at 70-75#, but without feathers they seems to be rather weak and fly way to the right/nock left to the target;
Can few points less on spine tester (my carbons are static spined at #80) make such a big difference in field or maybe I’m doing something wrong?  I even striped feathers from two of my carbons to see if it’s going to make any difference but it didn’t: they fly perfectly straight and land in the same spot where rest of the fletched ones even at very long distances.
Wood arrows  are 11/32 and 23/64, 291/2” long with 100 grain points, butt tapered to about 5/15-9/32”. I could  taper them for 5/16 70 grain points, just like I did with my footed arrows but I’m sure they would not last long in field.
Do You think it may help: putting very light points? Building up side plate on my bow (a have none) I don’t want to switch back to Dacron: that’s not an option.
Any suggestions?

  I'd say you need to try a heavier point, 120,140 grn arrow. It sounds like they are splined too stiff. I shoot 70 -75# splined arrows out of my 60# Osage bow, but they are 32" long and 120grn points.

carbons spined at #80 fly great, there is a very little (if any) difference in point of impact between fletched GT and GT bare shafts and that's how I expected woodies to perform.
They are little "fatter" than carbons and so I thought #70plus will be just fine or maybe a bit to stiff; 
Anyway I'm going to do some more tests tomorrow to see how they perform with lighter 70grains points

IMO I think you are headed in the wrong direction. I don't know squat about carbons,aluminum,, all I shoot is bamboo and wood. I have a Kodiack Super Mag that is 45# and I shoot wood arrows that are splined 45# out of it. The same with all my other 12 glass bows. I shoot the poudage arrow that is supposed to be shot out of it and they fly great. All with 120grn heads. The only time I go up in spline weight and length is when I shoot heavier stone points, 180-200grns.

I agree with Eddie. I think you need some weight on the tip end of those arrows. I would go up in spine at least to the bow weight. If you have any Douglas fir I would try those too. They are about 25% to 40% heavier than the POC. The heavier weight bow will handle the 600+ grain arrows fine.

ok, I'm throught... I took a few cedars without feathers (70-75 spine 29"long, just over 450grain with 70 grain field points) to test them with my recurve and broked 4 out of 5. Though they flew little better than yesterday (with 100 grain points) I haven't been able to get them fly straight like my carbon bare shafts. Its obvious that they are underspined for my bow (point impackt right, nock left- I'm right handed) witch is only 57@29"; I'm close to give up on woodies, only option I have left is to build up thick side plate and try one more time; otheerwise: anyone up for fancy wood arrows?
