So I just got a newsletter from my rep.
BR, lever, Tom, JCAT... I look forward to your response. On service and tuning.... what is better reference point on the cams to use as a timing reference??
Cut outs?
String posts?
Cable posts?
Lots of opinions per manufacturer but speaking on Barnett only

Once the crossbow is properly timed, I put a mark on each cam where the cable crosses. If it is a dark colored cam (example black), I use whiteout or mistake out. If the cam is light colored (example grey) I use a black Sharpie marker.
If they make a Sharpie marker in white, it would be better than whiteout or mistake out. The Sharpie is a permanent marker.
If my cams are timed for normal speed, then advanced for a different speed, they may have more than one mark on each, but still where the cable crosses each time.

All the best.

Thats a whole different story. If they are the same they are in time as long as the limbs are equal. Proper/perfect time would be set by ATA and power stroke measurement/brace height. I fallow these parameters and chrono speeds. They can really have you scratching your head some times. Thats why I like to take pics when it all comes together.

IMO, the cams are in sync when the exact amount of string wrap around the cams are the same and the string exits the cam at the same location for both cams. I usually will mark the cams at that spot with a pencil and compare. Then use any other other available reference to help keep tabs on it.

In the picture you submitted: look at the red color of your cable in reference to the hole near it. Both top and bottom cams appear to be in time. In the picture the cable splits that hole (half on each side). If I were to adjust the cam timing: 1)if the crossbow was not up to the advertised speed or 2)wishing to advance my cams for more speed, I would mark the cams where the cable crosses. I now have a reference point should I wish to return to the original setting or later on when changing cables.

As a further check, when the crossbow is cocked, I would see how the cams compare.

All the best.

Thanks guys. True it is a bit of a head scratcher cause for every person asked you'll get conflicting answers. According to the "experts" that design them only cable posts should be used. I dont really agree with that. That's why I threw it out to all. We at least take the time to really work out best remedies

I noticed in the pics that some bows are at rest but at least one is cocked. Should be timing be set (checked on) cocked or uncocked?

I think both. Just as well as cam lean etc.

X2. Usually they will both be good cocked and uncocked unless you have a weak limb. I always make sure I look at cam lean cocked. I will also measure ATA top limbs and bottom limbs if they are the same. Cam lean is usually good.

Don't forget some manufacturers use timming marks on the cam for ur use that disect the limbs!!
Not always accurate on the Mark's though. Barnett doesn't have a definate "mark" per say. The newsletter I received from my Barnett rep.
