RE-Spined
Pat B:
When using cane or hardwood shoot arrows you can subtract 10# for the natural taper of the shafts so you should be able to shoot a 60# spined arrow from a 50# bow and they should be compatible. Pat
Justin Snyder:
As you increase the weight of the point, the spine decreases. Normal is 125 grains for every 25 over that you can subtract about 5# of spine. If your arrows spine 60-70 you could subtract 5# for the extra length, then put a 190grain point and subtract about 10# more. That leaves you with a spine of 45-55#. What kind of bow are you shooting and is it center shot. If it is a selfbow or straight bow, you need to subtract about 5-10# from the bow weight to determine the spine weight you need. Justin

Top is no cut out, Bottom is, only tried bottom, spined the arrows for the Top 50#@28 Bow. The arrows shoot Center with the 35# Bottom pic.
I'll make a Vid to show.
The first vid is 35#Bow
The second is 50# Bow
Not much room to paradox.
Not even sure if the spine tester I made is accurate, so I'm making another.
They Shoot good enough.

Hi PK,
I'd love to see those videos. Is there any kind of tutorial out there? I am just getting started. I have a self bow that I think has 70# of pull at 28 in (It's an arm killer). In order to make traditional arrows for it I have to match the spliine weight of the arrow (or, it's deflection at X weight out at some distance on the arrow) to the bow, right???
Hope you guys don't mind a real novice asking about what you obviously know very well.
Jess

Hi Jess I am a Novice to but just realized I'm better at Bowmaking than Arrow spining, Still learning.
Videos may be on youtube about archers paradox those just show arrows doin the swiggley. :o
