I just picked up some 1535 blems from BigJim and when I opened them up noticed they looked longer than expected. They measured 32" end to end not including nock. Everywhere I have looked at 1535s lists them at 30" full length. My question is do they sometimes erroneously stamp higher spines and sell them as blems? I don't have access to a spine tester to see if they are in the ball park.
I just measured one I bought recently, and it is 30".
I bought some GT 15/35 blems from Big Jim a year ago and they were 32" also.They shot great out of a couple of lighter weight bows I have.Weigh them on a grain scale,you can usally figure out if they are missmared.Compare them to the weights on the GT website.Mine were 32" long.
I should be getting mine in this afternoon - I'll check when they arrive and let you know what my 1535 blems measure.
BTW, I wouldn't be surprised if you measured them on a spine tester and they came out closer to 500 than 600. For some reason, carbon arrows measure stiffer than they actually are on a spine tester designed for wood arrows. I don't know why; maybe it has something to do with dynamic spine vs. static spine.
I believe spine testers for wood measure 26" so that would account for carbon/aluminum showing more since they should be spined on a 28" tester.
(At least, that's my understanding and would not bet my house on it.)
McDave. As you know, woodies are spined with a 2# weight suspended from the center of the shaft suspended from posts 26 inches apart. Easton developed the measurement for carbon arrows. It uses a 1.94# weight on shafts suspended on posts 28 inches apart. The posts 26 inches apart yield a higher spine rating/lower deflection.
Found a conversion chart at www.RangersArchery.com (http://www.rangersarchery.com) recently. Here's one example of the difference. A 50# spine is reflected by a .52 deflection with a 2# weight suspended from posts 26 inches apart, and .63 with the 1.94# weight suspended from posts 28 inches apart.
Or, looking it it from the deflection perspective, a .63 deflection using the 28-inch measurement yields a 50# spine. A .63 deflection using 2# suspended from posts 26 inches apart yields a spine of 41#.
You should ask Big Jim but I think the arrow are made at 32 and then are cut to 30". If the arrow is designated a blem it is not cut.
Assuming this is true, would this be a good reason to cut some from each end rather than just cutting to length from one end?
McDave I've always cut equal amounts off of both ends. Just the way I was taught.
what you purchased was the "dark woods". Those shafts were originally contracted out by Bear Paw out of Germany and they called them the timber sticks.
Identical in every way except the pattern is darker with more visual grain to it. Bear Paw ordered their stuff in 32"s.
THESE ARE THE SAME 1535'S IN EVERY WAY!, except looks and length.
I had a long talk with them yesterday and again suggested that they offer the 1535's in 32". Eventually the will. that is how we got the 3555's in 32" ...pesistance.
thanks, bigjim
The good news is, if you order from Jim, they can cut them to any length you need ;) :thumbsup:
The best thing to do when you order is to not assume the arrow is 30 inches and ask.
Jim, Thanks For nagging GT, I find having longer shafts is handy but somehow it doesn't impress the chicks. :dunno:
DANG....the only reason I haven't ordered 1535's before is because they AREN'T 32". Big Jim, I just looked on your website for "dark woods" and didn't see any. Are they all gone? Thanks!
Thanks for the info Jim, haven't messed with carbon much and didn't know.
Although true for all brands of carbon, GoldTip actually recommends cutting arrows from each end. Imperfections found in straightness are more pronounced at the ends of the shafts. In this manner a guy trimming a 32" shaft down to 28" may actually end up with the next higher level of straightness from the cheaper arrow.

talk to them about the 35/55's too!
Daniel, the 3555's are already in 32" for the regular wood grain and dark wood grain....this year however, they will all be labeled by spine, ie. 600,500,400,340.
Unless Gold Tip has a few of the timbersticks left in either blem or non blem, there will be no more as Bear Paw has chosen to move their business to China to save money.
I am looking in to getting my own custom pattern but they require a large commitment...never been a problem, but so many people wait for the blems that it might be difficult to sell the necessary non blems to meet the commitment.
I won't give up the fight.
thanks, bigjim
And no, Large does not have any more dark woods in 1535. I bought the last two dozen he had this past Saturday.

I just went and checked Bearpaw's website and you are correct. :o
Its very disappointing, they have kept the timberstick name, but forgot to mention its no longer made by GT. The replacement does not have anyway near the same gpi, which to me is one of the reasons to buying them. I wanted something similar to wood in weight.
They still have GT Trads on their website, but I guess that will not be forever. Laughably theGT tras are cheaper than the new, supposedly Chinese, made arrows... :(
Hope they don't live to regret that.

Big Jim,
I have a Hill style bow cut to 1/8". Its 52lb at 27" and I draw 25.5". I wish to use 125 grn tips and wonder if I will be able to cut the arrow short enough. What do you think?
Cheers
Alex
McDave,
It's been a long time since my Basic Mechanical Skills training that I went through, but somebody can correct me if I'm wrong. There are lots of cylindrical things that the primary source of being "out of round" is at the ends, bar stock, etc. I think they call it runout or something. So I think the answer to your question is yes, cutting small amounts from each end would have a higher probability of bring something of .006 straightness closer to .003 or .001. Whether are not it is worth your effort to do so is probably 100% mental.
