Someone PLEASE help with my Bowtech
 
Before I start, I love my Bowtech bow (2006 Allegiance). Been shooting at least 40 times / week throughout the pre-season and recently the limbs starting cracking. So for safety I returned the limbs through a dealer.

When I got the bow back from the dealer, Ibare shaft tested the bow and found the arrows were hitting 6 inches to the left with a HARDfishtail to the right(field point to the left / nock to the right). From what I understand this tells me the arrows are over spined (Easton superslim 300's with 100 grain point). I also measured the limb pockets to the string, and they were the same.

I had to re-align and re-setthe rest with a laser and stillhave the same result with the bare shaft test. I found the weight pulled back is only 62 pounds when the bow is cranked (70pound bow). Does anyone know what gives?

If the limbs have been replaced, should I need to re-adjust the bow this much? Why can't I get the bow back up to 70 pounds? . My broadheads group out to 50yards, but I can see the fletchings catch the arrow through my site window and REALLY bothers me.

Thanks for any help.

Have a dealer go over the bow--it's their job.Maybe you got 60# limbs by accident?They should have checked what the bow was at after they worked on it!

If your only getting 62lbs, the dealer may have untwisted your cables. Check yoru BH and ATA to see if they are in spec. If not, twist the cables to get your weight back

I've received the wrong limbs before. I have some new ones I need to install, I won't know until I put them on. Good luck, BTW, what is wrong with 60# limbs? Sounds like that is what has happen, they will replace them again, but you may want to wait until season is over.

Most of the time your limbs are not in stock, and when they get made is when the mess up occurs.

Sounds like the wrong limbs to me. Do your cables have about one complete twist per inch or do they look like there is nearly no twist in them?

RE: Someone PLEASE help with my Bowtech
 
Thanks for all the responses. They are GREATLY appreciated. Those were my guesses, but again only guesses. I really hope the dealer didn't install 60 pound limbs. He had stated there were three sets of limbs returned to him, for a need of two sets. (not sure why the third set came back to him).

When I got the bow back, the peep did not come back to the orignal setting I had it when I was at full draw.So that almost confirms the string may have become untwisted (but to loose 6-8 ponuds of draw weight?).I will have a look at that again. I am going to pick up a new string tonight, so I hope that alleviates some of the problem.

There's nothing wrong with 60 pounddraw weightbut my arrows are set-up for a higher draw poundage, using 300 Easton Superslims they have a stonger spine, so I'm hoping to get the match with the 70 ponud draw. If not, I'd rather go to a higher point weight (125 grains) to get the arrows to fly true rather then new arrows.

Thanks again for the responses.

I tend to agree with the others. That big of a drop in weight signals something significant...be it different weight limbs or a cable/string issue. The shop/Bowtech should be able to confirm what weight the limbs are fairly simply.

Please keep us updated as to what happens.

RE: Someone PLEASE help with my Bowtech
 
You can loose 10 pounds of draw weight in only a few twists on the cables. A lot less than what you'd think.

RE: Someone PLEASE help with my Bowtech
 
My Old Glory went up about 3 pounds per 10 twists of the cables. I think you'd notice if there were +/- 30 extra twists.

I agree, I just replaced my cables on a older PSE and max'd out it was 66lbs. I put in 15 twist to get it to 70lbs.

RE: Someone PLEASE help with my Bowtech
 
with that many twists in the string, how did it affect your draw length?

KodiakArcher 10-02-2007 01:43 PM

RE: Someone PLEASE help with my Bowtech
 
Twists were in the cables not the string but I was installing new cables and getting them adjusted into spec so it didn't effect the draw length at all once I had the poundage back where it was supposed to be. If you were twisting them up to get more preload on the limbs (increase the poundage) you'd alter the cam rotation which would effectively lengthen your draw on a 2 cam bow like yours but you could get it back by adjusting the draw stop though you wouldn't have the same let-off in the end and you'd loose some efficiency depending on the draw module you have installed; cause and effect. That's why limbs, cams/modules, cables and string all need to be matched.

For future reference, after you get it back to where you want, and have your bareshafts flying perfectly, carefully measure all the critcal specs and write them down. Diagnosing problems becomes much easier if you know your brace height, ATA, peep locatioon and string nock are exactly in the same position they were when the bow was shooting perfectly. I like to make sure my measurements are accurate to at least 1/32". Small differences in these measurements can make for a large difference in arrow flight.

It slightly changes it, but one should do things in order. They should twist cables and strings to get things in spec, then adjust draw.

RE: Someone PLEASE help with my Bowtech
 
Thanks again. Imark everything on my bow to the location (make sure nothing moves in travel) but never tabledthe specific measurements. I'll make sure I do that this time around.

I did put on a new string and cables last night and started from scratchAfterwards. much to my surprisethe poundage was found to be at73 pounds, with 5 added twists to each cable. I did a "short" distance bare shaft test at 8 yards (the available distance inmy garage) where I found it still has a slight fishtail from left to right (not as noticeable as before) but in the same hole.More to come this evening when I can get the target outside and shoot at least 15-20 yards.

The dealer called melast night concerned about the bow, which I thought was great with some recommendations and willingness to help if I can get the bow back to him.

Does anyone recommend detailedliterature on setting up a bow from scratch, both traditional and compound?

thanks again

Download the Easton Tuning Guide from their website.

You've got yourself a great dealer there... Be sure to keep giving him your business; that's a rarity in today's world, it's sad to say.

This is a techie forum willy. I found out the only way you can ever learn is to screw it up from time to time. Just my 2cents.

Ain't that the truth!? Our motto for this forum should be something along the lines of; "If it ain't broke, #$@* with it 'til it is, then learn how to fix it."

I am going to have to steal that motto. I am like a meth addict taking things apart my friends say.

Oh there is nothing wrong with messing with stuff, you just have to be kind of careful what you do mess with. ATA and draw and cables, have to be careful. I work on stuff every week that wouldn't have been that big of a problem until they messed with it. If your bow is out of warrenty then i say go for it. If its not, don't be mad when they won't cover it. JM2C

Not surewhat's wrong but but it still isn't fixed. Will be taking it to a new archery shop tonight. It's got to be something so simple that I must be just missing it.

Check the cam lean at full draw compared to at rest. The '06 Binary cams have an issue with cam lean that they tried to correct by redesigning them in '07.
