    I have recently accidentally dry fired my new Helim. #-o :oops: The only thing i saw that was wrong at first was that the string came off. I took the bow back so they could put the string back on. I told them what happened and they look the bow over for me and found the cam was bent. So they replaced the cam and put the string back on. Now when I fire it their is a vibration that can be heard and i can feel it in the grip. The guys at the shop say they Can’t hear anything. So I took my bow to another shop and they heard it but really don’t know what or where. The only thing they think it is is the arrow rest. Does anyone have any ideas what else it could be?

    have you tried hitting the riser with your hand to vibrate it? i have done that before to find a vibration, and it turned out being a loose sight screw. have you gone over all the screws to make sure they are tight?

    If you have another rest try it, or see if the dealer has a demo one for you to try. At least it will confirm or eliminate that one.

    That has happened. I heard a rattle noise and couldn’t figure it out. I hit the riser with the palm of my hand until I found it. It was a loose sight screw.

    Take all the accessories off one at a time till you are sure it is not it. Put a whisker Biscuit rest on it at the retailers so you can see if it is the rest. The screws might need to be tightened on the new cam as well. See the last page on here towards the bottom.

    Pretty much what everyone said above!

    Sorry to hear about the dry fire. From now on make sure you nock an arrow before you draw your bow.

    How are you living your Dash?

    the shop first checked all the screws but haven’t tried a different rest. that is a good idea. hopefully that is the problem.

    Personally, I’d start with remeasuring the specs and cam rotation.

    Next, I’d paper tune it.

    Once I have confidence the bow is in spec and tuned, then I’d start chasing vibrations. [=}=]

    Also, for the next several months I’d make a routine of running a cotton ball over the limbs looking for splinters.

    All that was done to. But I do like the idea for the limbs. Haven’t thought of that. I am hoping it is something simple

    I’d then check to see if the cable and string have about the same number of twists and about the same tension … pluck them like a guitar and see if they sound about the same. If one or the other is carrying most of the load, then the bow will have more vibrations than normal.

    Also, check the positioning of the string grub. Its location will affect bow vibration and speed.

    Did you check your dead end string stop? Mine came lose I could here it at the shot was super annoying and then realized it was loose when I drew back and saw it was moving when the string was resting on it the dead end string stop was fine but when shot it hit it and rattled then stopped. Hope that helps.
