5 curve profiles
« on: April 30, 2019, 02:13:49 pm »
This is a new design for me and I'm wondering how these profiles look to you. I can say that the set back handle has a noticeable give at full draw, and given the length, the bow shoots pretty comfortably. 

Please feel free to rip it apart.  :)

That's purty :D :D. Must have driven you nuts tillering it. It looks so right and wrong at the same time.

That it exactly DC! It's so hard to know if you've got it right.  :-\

Well you got more experience with that design than I do. I might take a little off the inners if I had to take any more. Really hard to tell but doesn't seem like deflex is being over stressed. Might help save your handle area from working a little.
I really like it though Jeff. Always wanted to try one myself.

Thanks for your thoughts everyone.

Mafort, it's 52" long. It's made with 3 lams- ash, cherry, osage. I think lams or sinew are the only ways to get a bow like this to REALLY hold it's profile over time. Sinew would also allow you to make a short bow bend further.  :OK

That's a good way to look at it Don!

BJ, I think you're right about those inners. I think I'll work them with some 80 grit. Always good to hear your thoughts.  :)

Cool shape! Doesn't look stressed to me. But if, I'm with bjrogg - maybe the Inneres a bit.
I have a narrow long ash stave which has a natural profile in it, like yours - more or less. You give me some inspiration for this one!

That is awesome, love those curves! I agree with the others that you can get some more off the inners, leave the outers alone, they look maxed out to me

Nioce bow Jeff! I know the tillering of those 5 curves is something special.
I like the profiles, esp. the unbraced. If it's up to me, I would go for an asymmetrical bow with that pronounced curves (only my opinion).

I'm with the others, if you need more draw work on inners.

Is it osage?

I love it when there's agreement amongst skilled bowyers. The inners got some scrapes.  :OK

Promise I'll report out on the performance once I get her all finished up Arvin. I wonder how she'd do in the appropriate flight shooting category.

Simson, it's ash, cherry, and osage. I thought it'd be hard to get a bow like this to hold its shape without some laminating.
