    Default Alien Z cam lean

    My freinds Alien Z has alot of cam lean to the left and his string are prematurely wearing. Whats the cure? Also the factory strings are JUNK! 500 shots and I have had to reserve the string stop and today the string at the nocking point was showing through the serving. Told him to order a new set of strings, but need to get the cam lean out first. Might have to send it to Martin. Bow shoots great but I am dissapointed in the difficulties we are seeing in a brand new bow.

    When I first got my Alien Z, the bow was set at the lowest draw setting and I was so excited to shoot it that I just picked up the bow and shot it. At the shortest draw setting on the Hybrix 2 cams the bow had a lot of cam lean or limb twist. Once I set the cam at the 30.5 inch setting the cam lean or limb twist was not very noticeable. I had issues trying to get a good paper tune and could not get the left tear out until I got rid of the roller cable guard and installed a tilt tamer. This radically changed the shooting, centershot and torque on the riser -- but it sounds like the bow is shooting good? Do you have cam lean at full draw or at brace? I could not stand the side torque on the Alien Z, but once I got rid of it the bow was awesome. I am not sure that you can tune the lean out of the cams since we don't have yolk cables. I suppose that leaves reducing side torque from cables or stiffer limbs to keep limbs from twisting. Could it be possible that the cams or bearings are bad? Can you take a picture of the cam from behind at draw and rest?

    I think that some have also swapped top and bottoms limbs to try to limit limb twist.

    Bow is maxed at 50lbs and draw lenght is 29" the cams are leaning at rest. I don't have the bow right now so I will try to send some pictures soon. Can you replace the rollers with a slide? The riser is cut out for the roller guide.

    I bought the cable slide kit from Martin. It bolts right into the slide cut out. Then I put a tilt tamer on the cable rod. Took most of all side torque out of the bow and the centershot moved away from riser. The left tear went away. Here are some pics. If you get one from Martin you need to talk to Tech support to get the part numbers. I truly don't know how much the cable slide would have improved the bow without the tilt tamer since I put it on right away. When I get my bow back from Martin, I may just put on a belt cable rod to make things cleaner and lighter. Notice how the center shot on the bow is after the tilt tamer. Before that the rest was way closer to the riser and the arrow was pointing way to the right at brace.

    Bob, sorry I meant to write a bent cable rod. I believe a couple of people on AT are selling them anodized.

    Now I've got myself thinking ( dangerous thing ), I would like to get rid of the roller gizmo on my Diamond Iceman. Smoothest 32" ata bow I've ever pulled, but have fletching clearance issues with my Blazers. Have to shoot cock vane out to clear the cables. UUummMhhH.

    Bob,

    I agree, the roller cables look good, and add some preloading to the limbs but man they can add a lot of side torque to the bow. On my Alien Z I could feel the tension that the cable guard put in the riser. When the tilt tamer was on the tension was immediately gone. As you know a lot of the companies are trying to get away from the torque by using different devices. There is a reason that the target bows don't have the stupid roller cables. Tell your buddy that once he gets the torque out of the bow he will be in need of new arrows.

    Bob,

    Diamond cam out with a flex guard option for the 2010 Diamond Iceman. You could probably retrofit?
