acker:
Thank you badger :)
A compliment from one off the master bowyers is always a nice thing to hear / read :)
Yes , I heard of the program and i really would love to have it .
I'll send you an Pm with my Email address .
Thanks acker
Jaro:
Actually all my heavy bows seem to comply rather well with predicted mass, I have made few which are lighter and they also shoot better. These are mostly selfbows.

acker:
I calculated the mass again the way Badger told me to.
Now the mass seems to be allright on that bow.

Badger:
If you are working with a dense wood for instance you may find that you can't get the formula to work. When this happens the formula is telling you to redesign the bow. A boo backed ipe would be almost impossible to make at 100# and 76" long unless you made the tiller elyptical, by the same token using a very light weight wood might require that you use an arc of the circle tiller inorder to maintain the elb cross section.

Justin Snyder:
I have only made a couple of ELB style bows with 7/8 cross section, and they came in under the physical weight projected by Steve's mass theory. They seemed to be just fine for a couple of months, but then they really started to take set. This in spite of the fact that they were exceptional quality wood. One was boo backed Ipe. I for on think that the formula is a great guideline to estimate with.
