So I just got back from the bow shop. My bow was out of whack a little. Everything is spot on now, ATA, Brace, Timing of the rest, cams in sync, however, when I had new Barn Burner strings put on the moment I bought it the poundage was at 72. Now, 2 yrs later with the bow being in spec it's at 69.7 lbs. Not a big deal really, but I am curious as to why it dropped. Most bows when maxed out are a bit over not under in my experience.
yeh, they sure do. I figured since I hadn't shot a lot over those 2 years that it wouldn't have stretched much if at all, I was wrong
I most certainly wouldn't call myself an expert, but I'll have a go at it. I've had shops miss the detail of making sure it hits peak poundage when having the specs reset and timing done quite frequently, new string set or old. Axle to axle spec and brace height are not super precise, most shops call them good within a 1/4" of actual spec. That could equate to a 1/2" difference between two setups. So, the longer the string, the more poundage. The shorter the cables (axle to axle), the more poundage. Bet they have your string a bit shorter than it should be, and/or axle to axle a bit on the long side. As long as it is in time and tuned well, not really a big deal. But I think you feel that way and are just curious as to why. If you measure, I'd bet that axle to axle is a bit long and/or brace height is a bit off. Can also be quite a bit of difference in scale accuracy, if a different scale was used between the two. My hand held LCA scale reads about 1.2 lbs higher than my local shop's scale does.
Have them put about 6 twists on each cable end...ain't even gotta worry about lacking poundage then ...just kidding...better not.
I saw him measure the ata. It was spot on. I figured it was stretch. But I would still think that if everyThing is in spec then it should be at 70 or a bit more. Most bows I have owned are always a lb or 3 above .. some bows come in hot I guess. I had an elite that didn’t . It’s not a big deal, I just couldn’t wrap my head around the whole specs being on spot and not getting the actual 70# mark. They are barn burner strings. I have always like winners choice. Are barn burner any good?
No expert either. My first reaction was string stretch as well. That's been addressed. But, it's my understanding that limbs will weaken over time. After all, they're under tension as well. I know that we have a lot better technology and materials. But, not impossible. Also, was the bow tested at the same shop? If so, did they get a newer setup? Is it more or less accurate? I'm a thinker and would be wondering the same things. Probably for nothing. Welcome to my world.
Same shop. Not sure if they have a different scale. I wouldn’t think so. I can’t see a 2-3 yr old bow loosing poundage because the limbs are weaker. Probably more to do with cables stretching than anything. I just can’t understand why it dropped. If all is in spec, it should still be 72# however, if the bow became untuned then something went wrong. But there are many variables
I don’t even worry about ata, if it’s close it’s close enough. Time the cams, make sure the draw length is spot on. After they are timed then add or subtract equal twist of the cables to get your peak weight where it needs to be. Finished
Well I was reading a bit on this and apparently the scale can differ from one person to the next with the same scale . The scale may be accurate but how fast it’s pulled can make it read differently. Who knew? Not me. All is in spect right now I guess if I started twisting it would throw some specs out of whack. I’m thinking the bow was not in spec when I bought it, I mean it may have been close I don’t recall. Most every bow I have ever had ran 1-4 lbs higher when maxed out. Most never come in lower
That's crazy every bow I have owned have always been a few lower. Sent from my Pixel 6 using Tapatalk
Really? It’s not a big deal. It’s a 70# bow maxed at 69.7 so it’s right there. Just used to them always heavier. It’s tuned and shooting well. But I am so for new strings and cables after this season. I will go back to winners choice. I have always had good luck with them. The barn burner on there now are good but know nothing about them
If you have access to a press you can play with cable twists and see if you can get it where you want. Hopefully this chart will help.
