Thanks. One Q, is the chart you have based on 28" arrows? If I made the arrows 25"-26" long, will it change the result?

On the spine tester the arrow supports are 26" apart so yer arra's have to be at least that lomg. I don't think it matters if their 26, 28 or 32" See the thread " all about spine" for more info.

Yep, I'm planing on making my arrows that long.

For each inch under 28" you will add 5# of spine weight...so if you have a 25"arrow that was spine weighted at 50# you add 3x5#= 15# of spine weight so the 50# arrows are actually 65#@25".
   When you get into cane and shoot arrows this all applies but also you have to allow for the natural taper. We will jump off that bridge when we get there.  ;D   Pat

ps.Sean, I have 9 nice thin bambusa canes to send you. Sometime next week.

Thanks so much Pat, I'll like working with them.
Yes, that's what I was going for. So, if the spine tester is 26" long, will it test the arrows differently?

I know this is confusing but the uprights are set at 26" and a 28" arrow is the AMO (Archery Manufactorers Organization) standard. So what you will need to do is start with at least 28" shaft and after spine testing it cut it to your length...just remember to add 5# for each inch removed from the 28" shaft.
   I draw 26" but cut my arrows to 29" so I can subtract 5# for the inch over 28". Pat

So, the arrows have to spine about 15# lighter than the reading before I cut them down?
