String to Limb

[Oct.1]

I have a Parker UL-31 my question is:
When adjusting the distance from the string to the limbs on a single cam bow, do you measure to the string or to the center of the pin that holds the cam and wheel?

What is it you are trying to measure?
Axle to Axle ?
Brace Height?
Tiller?

Here's an illustration that might help ya:

Thanks for the drawing.
Now for the correct terminology.
I want to check the limb tiller distance.
At one time someone said to be correct because of the offset in the cam that you had to use the center of the pin that holds the cam and wheel on the limb and not the string.

Thanks for the responce Michihunter.

I tried both ways.
The bow is now paper tuned perfectly.

No problem. If I may, I suggest now that you have paper tuned, you might want to think of going one step further and broadhead tune using the following chart as a guide(this will insure that you are tuned completely):

Thanks again,
I usually tune my own bows. Just got to thinking when I was told to put a piece of string around the cam pin to the wheel pin and use that as the marker to set the tiller distance.
It seems that this way of measuring would cause the end of the string at the wheel end to return reach the riser before the cam end. This may cause arrow jump. So just for kicks I tried both ways. It appears my theory was correct because the arrow flight while paper tuning is perfect at 6 yards out to 20 yards. I didn’t check any further with paper. From there I watched the arrow travel from 40 yards. It’s a very straight flight. No arrow jump or deflection. As for broad heads I use a spinner and align the blades to the fetches. No noticable differance between broad heads or field tips.
