I shoot a Thunder Stick Mag. 50@18. I draw 28ins. I'm shooting 50-55 & 55-60 cedars.With Zwickey Deltas. According to want I can find, these are on the light spine side. When I cut the to 28ins. to stiffen the spine, they shoot high & left consistently. This should show as too stiff spine. I tried a 50-55 at 29 ins. w/ a 130 Delta & a 55-60 w/ a 175 Ace. Both shot where I was looking. Any ideas? I can work with this I'm just a little confused.
I don't see what the problem is. Shooting left would be an indication of too stiff for a right handed shooter. Though I'm a bit surprised that cutting off an inch makes them too stiff. On several different bows I have, from cut 1/8 from center to 1/8 past center, I can usually overspine by 10-15# or more with woodies and still get good flight. By cutting an inch off the shaft, you're only increasing the dynamic spine by 5# or so. That shouldn't be enough to make much difference in arrow impact IMO. Regardless, you have two combinations that apparently work well.
Yes, the two combinations work well. Maybe I worded it wrong. It isn't a problem so much as an oddity. From listening to advise on the forums to Stu Millers calculator, I should be using a heavier spined arrow. I used the calculator by Stu miller & according to the figures I put in, those arrows are really underspined. Just curious.
i know what your problem is----------- you need to shoot left handed. loyd
You can shoot the arrows thru paper to see what they are really doing, but is sounds like the bow is telling you what arrow it likes to shoot.
I often find the Stu Miller calc gives me a stiffer wood arrow than what actually works best. Sometimes I think we overestimate the depth of cut.
Fletcher,
I'm checking with Jim Reynols now but, I understood that it was cut at 1/16.
Thanks Loyd. Your a good friend. :bigsmyl:
Butch, my comments are similar to Fletcher's. Calculators and formulas are all good but the proof is in the shooting, and it sounds to me like your bow is telling you exactly what it wants. I'd suggest you listen to it... :thumbsup:
For your reference most of my set ups are borderline underspined according to common guidelines, but that's just what they are, guidelines and suggestions. The proof is in the shooting.
What Loyd said...lol
I'm working on getting my lefty shooting down Loyd.
I'm gonna start searching for cheapo lefty recurve and longbow... bith need to be low poundage to start off.
God bless,Mudd
I'll get ya for that Mudd!
If they shoot good who cares about anything else really. I would just like to have a bow to shoot.
Big mistake selling both my bows at the same time. I know I was laid up with my arm but she's BACK BABY and I want to start shooting and I HAVE NO BOW.....crap
Jer Bear
Jerry send me your mailing address and poundage. If I have anything in your range you're welcome to use it until you can get proficient with your new bow once it gets there.
God bless,Mudd
