Measuring Center Shot

[JDL]

Gentlemen,

I've been trying like heck to figure out how to measure this accurately... Any tricks?

I wouldn't mind cheating if any of you guys happened to know the measurement on a Bear Patriot...   :D

I don't know if this is the best way, but you can put pieces of white adhesive tape on the upper and lower limbs of the bow, just above the riser or fadeouts.  Measure the width of the limbs at that point, divide by two, and make a mark in the center of the tape.  Hold the bow up in front of you, close one eye, and center the string on the marks you made.  See where the string crosses the arrow shelf (or the riser next to the arrow shelf, if the bow is not cut past center).  Or maybe the string will cross right at the intersection of the arrow shelf and the riser, and you will know the bow is cut to centershot.  Otherwise, measure the distance from where the string crosses to the where the riser meets the shelf and you will know how much the bow is either cut past or not quite to centershot.

I've been wondering this too. The spine calculator spreadsheet requires a centershot measurement. Seems like it requires a pretty precise measurement.

Thats what I'm thinking... If it was a half in. here and a half in there it would be one thing but when 1/16" is in question there has to be a trick to it.

I had a bow I ordered to match the 3/16" PAST center that Bob Morrison uses on his Cheyenne. Instead, it came "cut TO center."

I took calipers and measured the riser at the shelf area...then divided that in half and measured the meat left beyond the shelf cut. It was 1/2.

Seemed to me that whatever the overall riser width is at the shelf, what is left behind the shelf is the dimension that tells you if it's cut to center, shy of center or past center.

I just kept rasping it back till I had 3/16" past center so I could set it up to shoot the same arrows as the Morrison at nearly the same weight.

Dunno if that is right...but it worked.
