    Default Same Cam But Different

    Do you see anything different in the photos?
    The one on the left is from my Bengal and the one on the right is from my Silencer.

    Looks like they did some slight re-engineering. My guess is the one on the right is the newer design.

    Here's my concern. Maybe really not a big deal but noticeable so I decided to post and see what you gurus thought. Have shot both many times and this type of wear does not appear on the Bengal Fury cam which does not have as much string contact in this area. I think upon release and cycle the cam rocks back on the string hard right there. See previous uploaded photos.

    you have a sharp edge Take the string off and sand with fine sand paper 220 will work to get rid of the problem

    I would think there will still be string contact with either design. I do notice that the string appears to be coming straight off the Bengal cam, while it looks like there is a slight angle on the silencer, looks like there is a "pivot" point right where the serving is wearing. Might just be the picture angle, tough to say for sure. Lengthen the cable and/or shorten the string a few twists to rotate the cam around clockwise(as pictured). I'm not too familiar with the Fury but I think it's set up the same as the older single cams.

    The other cause could be a burr or sharp edge at that spot on the cam.

    It most likely is a sharp edge coupled with a touch of cam lean.. My Alien Z did the same thing with the Hybrix cam.. I removed the string and took a fine tooth rat-tail file the whole way around the groove to remove the edge. It adds just a touch of bevel to let the string slide into the groove. Also rub some string wax into the serving at that point.

    Something else I notice between the two is the different cam orientation and module settings. Two different draw lengths?

    You could probably do as CaptJJ said and change the cam orientation so it's more like the Bengal. Then change the module setting by 1/2" and the draw stop, too.

    And in case anybody from the new Martin management is reading these threads this is one of the issues we refer to as needing addressed when designing, machining cams and quality checks before the bows go out the door.

    Truly it is both cam lean and sharp edges. One other thing is 1/4 inch shorter string will not allow the cam not to bend that area. Also 3d serving is .017 you can use halo .014 which will give it more clearance. I have done 22 strand strings mixed with halo and got great results. More Clearance and fitting deeper into the groove.

    OK I think I am going to try the fit and finish process first and see what happens. If I decide to invest in a new set of strings I will take that offline with you Hutch. I bet the cam on the Silencer is an earlier version than the one on the Bengal. Oh yea and to answer a previous observation about the draw module being set different. The draw length is the same but the module must be set different on the two bows to achieve the same draw length. See http://www.martinarchery.com/2013/past_specs.php
    Will try the orientation thing as well.

    Thanks again for all the input....I learn cool stuff every time I log onto this site.

    OK one process at a time. Polished this area out this morning with 320 and then to 1200 and we will see what happens. Did notice a slight edge on the groove that I took off as you can see in the photo. Need a little more QA and QC at the machining shop.
