Length for Laminates
« on: March 15, 2010, 01:50:19 am »
I'm thinking about Perry reflex... Since the bending stresses are distributed internally as well as externally, does that mean you can make a bow shorter?  Like sinewing a shortbow?  How much shorter could a D bow be if it was a laminate?  For example, for a 30" draw, about 64" is likely as short as you'd go for most selfbow woods.  Would you go 60?  58? for a laminate?  Assuming "average" quality wood is used.

Your limiting factor is still going to be the tensile strain on the back and the compressive strain on the belly which will remain the same whether is a Perry reflex or not.  So I don't believe that Perry reflexing will allow you to safely shorten a bow.

I believe that Reflexing a Bow makes for a Bow with more Pep in it's Step...but will not allow it to be drawn any further before damage can occur...I think that in order to get more draw from a shorter Bow...you would have to put it into Deflex in order to accomplish this...deflexing a Bow at the Grip Area...allows for the wood to be under less stress...so you should be able to get more draw from a shorter piece of Wood...JMO....but I could be wrong...... :P
