Is there a way to make a carbon stiffer other than cutting it off? I have some that are still a little weak and I can't cut them off any more...Howard
-
Well the easiest way is to tune your bow to shoot the weaker spine.A slight change in centershot will allow you to use the arrows you have on hand.
-
you can either use a lighter field point
or
lower you brace height about 4 twists at a time until the arrow stiffens up.
-
If it's real close and you don't for whatever reason want to build out the bow like James recommends(it is the best way), you can foot the arrow with a piece of aluminum shaft, put a wrap on the back and use a longer fletch or four fletch. You'll stiffen it up a little that way.

They are GrizzlyStik Woodie 500 and they are for 60-70 and I am shooting them out of a PLX 52@28 and drawing 27" I cut them to 28" and they are still weak 125 up front. I have build out the side about a tooth pick and added 20 Grn of shot in the nock and the still show weak. I guess I will have to sell them and get 400.
-
The Woodie seem to be the opposite of the Banshees when it comes to stiffness. The fellows selling them told me the Woodies have been real weak spine.
-
I,ve had good luck with an 8 or 10 inch wooden dowel glued inside the shaft it changes how the shaft flexes.You may have to try different lengths much like cutting the arrow down.
-
Jeff, I think that would make them way to heavy they are already 630 grains now...Howard
-
Howard,It shouldn't add much more than 20-30 grains.It will also give you a little more FOC.Give it a try I think you'll be surprised.$1.50 for a small wooden dowel sure beats having to by stiffer shafts.
-
OK Jeff, I'll pick some up today. What size do you get 5/16?
-
I'd take the shaft with me and check the fit you want it to fit snug.You can always use a little sandpaper to get them just so. Don't forget to leave a little wiggle room for the epoxy.
-
Adding weight to the rear will also stiffen them up, not a lot of ways to do that though.
-
Tim, is right, ya can add weight to the rear. Actually lots of ways to do it, ya can foot the nock end, ya can epoxy some lead shot into the nock opening add a wrap that goes around twice. Shawn
-
I use hairspray!!! LOL
-
gold tip has some nock adapters you can use to add weight to the nock end on a 5/16" carbon arrow.
-
Have you confirmed that they are actually weak by changing point weight both up and down? If they really are weak a lighter tip should make it better and a heavier tip worse.
Just a thought. :)
