Leonwood, that's another absolutely beautiful bow. I'm glad to see your still pushing it and solving new problems. Beautiful work sir, as always top shelf.

Super clean work, Leon! Finish is excellent so as the profiles. A looker for sure.

Thanks guys! Glad you like it! Shot it some more and need my 70/75 spined arrows to get clean flight. Arrows buried crazy deep in the target so I am really happy with this one ;D

Is there any chance you could make a force draw chart of this bow?

Sure, will do that tonight! Can you explain me what use a force draw curve has for self bows except for checking if it stacks at the end?

It will tell you how much energy it stores and give you a clue to performance.

Sleek, force draw curve won't really tell you much about performance. Chrono is about the only way to do that. Force draws are useful when you are trying to dial in the losses on a bow but don't really tell you much on their own.

Just a short update:
Shot it through the chrono with my target arrow: 194 grain poc, 27 inch long, five inch helical fletch, 100 grain point.
Got an average speed of 177 fps drawing as far as the arrow would go. (My usual drawlength is not that long, probably about 26)

Will plot a fd curve tomorrow at work when I have access to a real computer

So I found this excel thing by Jim Thorne and figured that would could do the job. So this is what I came up with, is this any good?

   Leon, I am pretty sure your bow would test out faster than what you tested it at. It may have something to do with your style of release. For an accurate test you need to get off that string cleanly right at 28", maybe using a mechanical release. I would almost bet that the 394 grain arrow you are using would be much closer to 200 fps with a good test. I can see that bow easily shooting a 550 grain arrow at 180 fps or more.
