I've gone as far as even looked at a picture of the bow, and visually measured the string. When thats the case, I will over serve. This is mostly done on older bows, its next to impossible with a single cam.

PM sent Gibblet.

I made my own string jig out of two 2 x 6's. It works quite well.

2- 6' 2 x 6's

All bolt heads/nuts are 1/2" so one wrench adjusts everything

This jig and all of my stuff ended up getting stolen last year, so I re-made them the same, except I used thinner bolt shafts. I think either 1/4" or 3/8"

The bolt heads are embedded into the wood to make turning for making end loops easier. I use 4 C clamps to hold the jig in place while making a string.

I have a bunch more pictures of them on my computer, let me know if you need more, Its a pain uploading pics on dial up if they arent needed.
