Difficult to get a 62" yew bow to bend 28" draw. Yew will only bend so far before it blows up. For that short a bow it will likely have to bend through the handle like an ELB. Glenn St Charles had a suggested "rule" for draw length vs bow length in his book - something about "twice the draw plus X". Good luck with your project.
Post a pic of your current bow. Does it have these same specs?
