What do you all see?
Yew wood 62" NTN, 4 1/2" low brace, 30#@ 20" hoping for 45-47 lbs Two knots on lower limb look a little funky

Maybe a little more bend outer third to just before tip on left side but hard to say. Not bad at all for sure though.
-
To me the left side looks like it's bending pretty even. The outer third on the right side looks like it could bend a little more. DuBois is more experienced than me though so take it with a grain of salt. All in all, it's looking good. This is a critical phase of tillering so go slow and don't take off too much!
DuBois, are you sure you meant the left?
-
At first glance it looked really good to me. After starring i'm beggining to think the left is stiffer than the right. Where to takee off i'm less sure. Mybe midlimb between the knots on the left
-
Parallel limb profile or pyramid? That makes differnce in tiller shape. I'm assuming parallel, which means more bend in outers (maybe mids too) as was mentioned. I would leave inner thirds alone. It does seem that your "lower limb" is bending more than upper, which means you may need to swap them out if it's not too late for that. You may not hit upper forties with the corrections, but will for sure hit low to mid forties. Lookin good overall :)
-
I think you're looking pretty good overall. It's hard to judge bottom limb because of the two knots make it look deceptive. Be careful and watch that limb closely because hinges can sneak up on you quickly around those knots. Probably need to leave alittle stiff around them.
-
Looks really good. Just get the outer limbs moving a bit more and your there. Cheers- Brendan

I agree with k-hat. I can clearly see both at brace height and when drawn that the upper limb on the right is too stiff, ie the entire limb needs to be weakened until it bendst at least the same amount as the other. The entire upper limb needs to bend 1-2" more at full draw.
This issue usually shows up by more set occuring in the limb that is bending further(and is weaker), and looks like what is starting to happen in the unbraced bow.
-
Your right on K-hat Parallel limbs,
I did work on the stiffer upper limb and thinking I had it bang on. Its now pulling 45# @27", 5 1/4" brace.
I may have been a little quick pulling full draw with limbs not quite even. Like said the upper limb took more set then it all ready had and is still a bit stiff 1/8" in the inner and mid, and about 3/16" outer. see pix Thanks for the help.. Chuck

Now that I look after others replied I can see that upper limb is stiff outer 2/3 as well as what I was seeing earlier. Glad someone else chimed in on it.
Glad you're gonna get a nice bow from it. How about some front profile pics and also the knots?
-
What draw length do you want?
You can work the mid limb on of need be as you continue.

Brace is looking better, but if you look you still have a negative tiller. It would be an easy fix if you hadn't already shaped the grip (just flip it), which is why I usually wait until this point to shape mine just in case I have to do this. At brace you want the belly-to-string distance to be 1/8"-1/4" less on lower limb than top limb (positive tiller). As it is you'll need to continue weakening ths top limb and may lose a couple pounds.

Update, The Yew bow is now at 45 lbs at 28in. 5 1/4 Brace in this pic, and has taken a bit more set.

Thanks for looking and the help. Chuck

Looks very good to me Chuck. Your limbs are following the string a good bit obviously but many a sweet shooting bow has been made with a similar unbraced profile. I have to try a yew bow this year, thanks to Gun Doc and Goat I now have a couple staves of that PNW gold in the shop a waiting. :)
-
i like the bend on that
-
.... i agree with Mr. Bent... my sweet shooters half a bit of set to 'em
