Title: RD tiller question
Post by: DC on November 22, 2018, 02:16:50 pm
Right after glue up I traced the profile on to paper. As I tillered it gained about 3/4" of reflex. Then I screwed up a bit and it took some set in the fades. Now I'm at 40#@26". If you look at the picture what I think I'm seeing is it's still holding about 1/2" of "gained reflex" mid limb but the set in the fades has dropped the tips back to where they were right after glue up. Well within 1/4". I want to tiller it out to 40#@28".  I've never had the gained reflex last this long so I'm thinking it's over built mid limb. Should I side tiller mid limb where all I have to loose is some of the gained reflex?

Put your hands where we can see them and step away from the bow....   ;D ::)
It's fine IMO

I'm happy with the tiller as is but I want to go 2" more and I'm wondering if side tillering the mid limb is the way to do it.

Although now that I'm staring at it is there a bit of a flat spot at the arrow?

Maybe just a smidge. Perhaps you could scrape just a little there and get the remaining weight off with sandpaper?  (-P

I wouldn't take anything off the sides cause the width will give you stability and help it hold it's profile over time.

That's a good point.

I'd think you could get a bit more bend mid limb.

Ok... if pushed to say where I think it could work more ::).
I've marked 2 points that look thicker and don't seem to be bending much from the unbraced shape.
If you gain 1/8" movement near the fades, that ends up as 1/2" at the tip.... 1/2" at the tip is  1 1/2" extra draw.

I would definately not touch your mid limbs, right limb looks a little stiffer and I think if you scrape a little where Del's arrows are and a little at the last few inches just in front of the recurves you are done
