Tillering--your opinions please!

[WhistlingBadger]

So, as I mentioned in another thread, I had a tillering tree explode the other day.  I think my scale, which was blown to pieces, provided enough weight on the string that the bow wasn't damaged by the dry shoot.  But whew.  Let's not do that again, agreed?

Anyway, here's where I'm at now.  To me, the right (top) still looks a little stiff through the mid, even after thinning down.  It's at pretty close to perfect draw weight now.  Should I leave well enough alone or keep fiddling with it?  And if I do fiddle, should I thin it more or remove more from belly?  What says the PA oracle?

Looks like mid limb on the right need to bend more. It shouldn't take very many scrapes to fix it and that's the way I'd go.

What’s your width taper? In terms of just symmetry, the right side is bending more in the inner limb close to the fade.

[WhistlingBadger]

Ryan, I'll measure and see when I get home, but I believe it's about 1 3/4" at the fade and about 3/8 at the tip, even taper.

So, maybe a few scrapes off the left fade and the right middle?

I’m with pat. Hit that mid limb a little and it will change the overall bend of that limb. I wouldn’t try to match the left to right, more the other way around and I think thinning that mid limb a hair will do it.

I wouldn't touch the left fade until the right side is bending better. That looks like a near-hinge to me coming out of the fade on the right.

It might be helpful to see the unstrung profile.

That's exactly what I saw...

It is almost hinging off the right fade - that is what makes the mid-limb look stiff. Look at the thickness of left fade versus right fade...

[WhistlingBadger]

OK.  Did a little belly scraping on the right midlimb.  Better?  What now?

[Morgan]

That left limb looks perfect by my eye, the right is still bending too much right @ the fade. How close are you to your intended / desired draw weight?

[WhistlingBadger]

Thanks, Morgan.  It's actually right at my target weight--55#@27".  I'm sure it will lose a couple pounds as I shoot it in.  What, if anything, do I do about that too-bendy right fade?  I'm afraid if I take the bow down to where it evens out, it will be too light to hunt with.

Timbo and Hamish, I keep forgetting to take an unstrung pic, and I can only post to the forum at work.  (There's still some weirdness with the security on the site that won't let me post from my chromebook at home)  It is dead straight unstrung, if that helps.  No reflex, no string follow.

There are mixed opinions on this, but you could heat temper that weak spot to stiffen it up a little. It looks like you may have dipped a tiny amount too much as you ended the fade?  Evening that out along the limb might cost between 5 and 10 pounds. If it were me I'd try heat first

[Eric Krewson]

The left looks close to perfect to me, the hinge at the right fade throws all the rest of the limb off.

Sometimes this happens if you work down the the fade to the limb, it is easy to dish out a place. I always work up the fade from the limb after hinging a few fades  after rasping down them to the limb.
