Ausie,is it Gene that would post pictures of his sight setup with bow cant?
I wanted to post a picture of that in another discussion and didn't have any idea of where to find it but I was pretty sure he had something to do with the 4rth axis device.
I was doing this before that tool ever came out,I learned it from someone that has setup bows for a couple world record holders.
That is a sweet setup too,if I still shot a slide bar,I would be using that instead of the old creditcards that I used for shims.

Of course I probably would have made my own,I am cheap that way.
See level above,I wouldn't even buy one of those,I made mine but mine is much better.[:-]
