tillering question

[horatio1226]

I saw a build along here in which the bow was being tillered based on the draw of the arrow being off center.I believe that he had the bow handle in the tree and was pulling on the string where the arrow would be, which was an inch or 2 off center.The thing about the build along was the great graphics that he had setup behind the whole process.He made it very clear what a tillered bow with 2 different length limbs is supposed to look like using lines and arcs. Any help with this would be appreciated.I have been looking for it for hours and can't seem to find it.     Thanks
