Binary Cam Lean
 

Wow! I measured my cam lean on the '06 Old Glory I've been having issues with and the string deflects nearly 3/4" to the left (RH bow) between static and full draw. I know how to correct this on a yoke system but is there anything to be done with a binary setup other than move the rest out farther? It even appears that the cams are dragging the inside of the limb right in close to the axle/bearing.

Man, thats not right. I know you know this, but I would send back to bowtech. 3/4" is alot. There is some advantages to afixed yoke system

RE: Binary Cam Lean
 

Yeah, I liked the idea of the binary cams... at first.[&:] Now I'm tempted to put on some longer axles and make a set of yoked cables for it. I've got it shooting okay but that much lean just ain't right. My trusty old Hoyts shoot a lot better.

RE: Binary Cam Lean
 

Kodiak, if your cams are leaning enough to make limb contact, you need to have it looked at it by the shop where you purchased the bow.

RE: Binary Cam Lean
 

That's funny, I purchased it from me...[&:] (The store I was working at closed down in Jan.) Never seen this on any other bow to nearly this extent and if I have seen any cam lean, it's been a yoke system so I've been able to correct it. It's not the tip of the cam that's touching in the limb cutout, it just seems the bearing surface near the axle has a little excessive wear.

i checked out my constitution w/ len's full draw tool and a spott hogg laser. i owned it about 5 more minutes. darton's new system is interesting, but the yoke is only 6 strands, which make the end loops 3 strands per side - which is frikkin' nuts imho.

RE: Binary Cam Lean
 

Just a newbie question, that I thinkI have asked before but forgotten, does only the top cam lean on a dual cam bow(because of the yoke) or can both? Also, do idler wheels lean on a single cam bow?

RE: Binary Cam Lean
 

Cam lean on the Binary's seems to be something you have to live with. 3/4" is alot , but I don't know if it's excessive. Was it that bad before??
If your centershot has not changed I'd say it's always been that way.
I believe the lean is why the center shot on the bowtech's is so far out. My 06 Tribute is 15/16". I have alot of lean...more than i would call "right",
but it shoots great.
I checked the axles and limbs for cracks. No problem w/ either.

I would be curious to hear from more Bowtech shooters on this issue.

RE: Binary Cam Lean
 

rb, yes idlers lean, and so do bottom cams, but on non-dually's you can't do anything about it.

RE: Binary Cam Lean
 

I know that you have to adjust the yoke to get the cam to stop leaning and back on center, butI have only seen a yoke on the top cam, how do you adjust to get your dual cam bow's bottom cam back straight?

RE: Binary Cam Lean
 

true dually's have splityokes on top and bottom

RE: Binary Cam Lean
 

Really I have never seen that before. Is that on the older bows or do the newer ones have it too. Maybe with the new hybrid cams they don't need it? If it does not have a yoke then does it not lean?

RE: Binary Cam Lean
 

My '07 Allegiance's center shot is in the center. They'll fix the bow if it has cam lean.

I believe that is why they improved the cams from the '06 and earlier models. To lump all of the Bowtech's with an issue you are having with yours isn't exactly right.

Dave,
I don't consider the cams leaning an issue. I had thought it was a problem, but alot of Bowtechs 2006 and older had center shots at 15/16". And I'm not lumping all Bowtechs together. Binarys' lean by virtue of the design. Just some more than others.

Are you saying that it's the cams that cause the lean? If so, do you think it's possible to get the newer cams for my tribby. If the string and cable lenghts are the same between the '06 and '07 , I would think so.

RE: Binary Cam Lean
 

According to what I've read it was the cam design of the Bowtech's that caused the lean and they've redesigned to eliminate the cam lean. When I bought my bow the guy checked it for cam lean.

There was a batch for '07 that did have cam lean and Bowtech will replace the cams if you call about the issue.

You could talk to Bowtech. I thought though that they would even fix your '06 if it has cam lean issues.

RE: Binary Cam Lean
 

I was in contact w/ a Bowtech teck. He never mentioned that they would do anything for me. I don't think he saw it as a problem from the way he talked.
I even had a Bowtechshop owner tell me that the lean was because the limbs were worn from shooting. I knew he was full of it.
I don't have any cam/limb contact so I'm assuming the lean that is there isn't anything to worry about.

RE: Binary Cam Lean
 

I have an 06 Tribute and the cams lean quite a bit on mine too. I contacted Bowtech about the possibility of putting the new cams on my Tribute but they said the new cams can not be retro fitted to the 06 bows. My Tribute shoots great so it really wasn't a big deal, and I have a Guardian that I shoot most of the time now anyway.

RE: Binary Cam Lean
 

you've got to check them at full draw also, and see where they are pointed then. that's what's going to tell you how much the tilt is changing from rest to full draw. as the bow is shot the cams will tilt back to where they were. this will cause your string to have some horizontal movement in it - or horizontal nock travel. anyway, its a lot easier to clean up right and left misses if your string is not moving horizontally.

RE: Binary Cam Lean
 

What is your center shot?

RE: Binary Cam Lean
 

I just got my limbs and cams replaced on my tribute last week. The cam was hitting the limb. Could barely get a piece of paper in between the two. Everythings good now.

RE: Binary Cam Lean
 

If BowTech didn't think it was a problem then why did they redesign the '07 cams to eliminate it?

RE: Binary Cam Lean
 

I find that surpising that the tech said that. If I took even an older Bowtech to the shop I bought mine he'd probably ship it back to Bowtech to get fixed.
