Bowtech's Timing Marks
 

Can anyone tell me if the timing dots are supposed to be even between the top cam and bottom cam? This is statically on my 08 Allegiance.



Thanks

YEP !

RE: Bowtech's Timing Marks
 

Yes, but I wouldn't get too carried away about it if they're close. Say 5/6.

Yep they should be the same. You shouldreally check Cam sync at full draw also. That's easier to do with a draw board, but you can get it plenty close enough without one.

I too asked this question a lot while learning how to tune these things. Here is the deal as I understand. The timing marks are ONLY a starting point to get the bow close. When cam timing/synch is set correctly, the dots WILL NOT match. The reason they won't match up is this. Our nocking point is not set at the true center of the string. It's above it. One cam will need to be advanced ahead of the other slightly in order to counter act this. If you have a draw board, use it. If not, I suggest building one. This will really show you exactly what is going on with these bows when you draw them.

Get the module draw stops on both cams to hit the cables at the exact same time at full draw. Then, look at the dots. Chances are, the bottom cam will be showing close to a half dot more than the top. ( I think I have this right:eek:)

One thing I had to contact several people on, including Bowtech was optimum cam position. This was the starting point the cams should be in at brace. For my 07 Alley, it was 4 dots. I set the bow to have 4 dots on each cam showing, then started to synch. Bow is in perfect time now and I have 80% letoff at full draw.

In addition- NO limbs, even the best laminated limbs like Barnsdale, Hoyt, etc are perfectly matched. At full draw there will be slight differences in deflection compared to at brace which will change the synch.

What I'm findingwith these binary systems is they are far less sensitive in out of synch conditions compared to a hybrid slave/CPS type system. Binaries lose some performance for sure, but they don't get all weird and sensitive to creep/tension in/at the wall/valley like a slave/CPS.

That is beautiful thing about them Jeff. I like to get my rigs down to a hair, but the average Bowhunter is still inpretty good shape when things are a little out;)

Jeff, great point about limb deflection. And you're exactly right about the cam system. It really does as advertised and isn't as sensitive to abnormalities in the system.

I absolutely love the binary system and it seems every year, Bowtech improves it a bit. That's one thing I really like about what Bowtech seems to be doing. They keep improving a good, solid design..not just move on to something else.

One other thing that makes the binary stand out to me is the amount of tunability you can get out of them. For us compulsive tinkerers...its neat to be able to adjust the draw stop peg a little and get an entirely different feel out of the bow. You really can tailor the feel of the bow to your liking.

RE: Bowtech's Timing Marks
 

Lots of good information here. The reason I asked this question is because I had the timing checked at full draw ata shopand theysaid it was on. However, when I got home and checked the dots the bottom cam is showing right at 5 and the top is showing not quite 4 dots. This puzzled me somewhat.

I have new strings and a new press on order so when they arrive I will be going into this for the first time. So looking for as much info as I can get prior to the event. Guess I will be making a draw board too since it appears as if it will be conducive.

Thanks for all the advice all.

Hey leave me out of this.:)

N2D, it's really not difficult at all to get the bow setup and synched properly. Just make absolutely certain that once your new strings and cables are broke in, you are getting the correct draw length and your bow is able to reach max weight before timing it. Mine didn't after string break in and, long story short, I ended up just pulling the string and cables off and twisting them to length under tension. This got it very close and gave me a good place to start tuning.

If you are talking about the Average remark? I would Never call you Average Tony!

Can someone explain how twisting or untwisting the cable will affect the top or bottom cam.
For example, twisting the ____ cable will result in the top cam being rotated a little more in ____ direction.
A good explanation would be much better than trial & error.

RE: Bowtech's Timing Marks
 

So does this mean that it is possible to have the correct Brace and AtoA but not be able to reach max poundage or have the proper DL?

RE: Bowtech's Timing Marks
 

N2D, yes, you can have your specs correct, but the draw weight and DL be off. This was exactly what happened to me when I replaced mine. It is far more important to be able to hit maximum draw weight and the correct draw length than to have your ATA and BH exactly to spec. Bowtech, and most manufacturers have a + -of 1/4" on specs. So, if you have a bow that lists with specs of 34" ATA and 7" BH. It is within spec if its 33 3/4" and 6 3/4", or a quarter inch longer than list spec.

Once I twisted my cables to length under 100lbs of tension and put them on the bow, my ATA and BH were within 1/8" and I got 70.4lbs on my scale. Draw length was about 1/8" long by my measurements, but felt almost perfect. I left it at that and tuned it from there.

RE: Bowtech's Timing Marks
 

Okay thanks MM. Looks like I have lots to learn but I will get er done. I've been printing off all this info for reference.

Ed,
Don't sweat it. It's not as hard as it sounds;)

Dan

RE: Bowtech's Timing Marks
 

LOL I know I am way out there in left field.:D:D

RE: Bowtech's Timing Marks
 

Only when you are Killin' Brats!!;)

Dan

RE: Bowtech's Timing Marks
 

Guys, setting these bows up really is easy once you understand them. Just take your time and study the cams, how the cables are routed and how the string is routed. Then imagine what would happen if one of the cables was twisted up some, shortening it. You'll start to visualize what that change will do to the cam rotation.

Don't make it harder than it really is!

RE: Bowtech's Timing Marks
 

I Agree MM!

Don't make a mountain out of a mole hill. You do it a couple of times and it's simple.
