Retrofitting Longer limb bolts
One thing I really like about older bow designs was the use of longer limb bolts to allow one to simply relax limb pressure by unscrewing the bolt until the string/cable(s) relaxed, eliminating the need for a bow press to do work.
I just learned that Newberry bows apparently does this, which is a big plus, in my book. I wonder why more manufactureres don't, not doing so makes little sense to me.
However, I'm left wondering why one can't simply have a qualifed machinist lengthen the limb bolt hole a bit and install longer bolts? If there is no big issue in doing so, how much longer of a bolt would it take to accomplish the desired no press needed feature?
