the mass theory and warbows

TBod:
I'm huge fan of the mass principle, respect!

Really like your chapter in tbb4.

Do you account for any wrapping of the handle on the charts on p 92 tbb4. Or what is normal for a wrapping.

Badger:
   Handles are something you just have to estimate on a bit, I pretty much based everything on a standard type self bow handle. If the bows are comming in over weight it usually means that the moisture is a bit high. If they are comming in underweight it can mean the moisture is too low.

acker:
@Badger: Thanks for your answer , you made a great work on that chapter impressive :)
my latest Elb:
78" long 100# @30"
Ends are a bit stiff and a less bending handle, tiller more elliptical.
trilam Bo /morado/ bloodwood
Weight 805g  but shouldn't the bow weight be something around 700g?
wide to depth ratio 1:1 ~   1:1,1
no perry reflex






Thanks acker

Yeomanbowman:
The only heavy bows I've managed to come close to Badger's mass target have been laminates and it didn't seem to be too critical (performance wise) as long as they were not overbuilt.  However, I think the mass placement is as important as anything as I'm sure he would agree.
Great theory though and I find it really handy when tillering and knowing when your getting close to about the right amount of wood.

Badger:
Aker, I consider that the ideal tiller for an elb of heavy weight, very nice bow there. I would calculate that with a 4" stiff handle and a 32" draw for a close mass estimation based on that tiller shape. David Dewey converted my mass theory into a calculator on an excel spread sheet. very handy and easy to use. Simply fill in the blanks and it spits out the answer. I have it on my other computer but will e email it to you if you like. Steve
