Could I get a tiller check please? It looks to me like it's hinging at the right fade but there is a hump there on the unbraced picture that is throwing me off. This is my first Saskatoon(Serviceberry). It's spliced. It's pulling 40# in the drawn picture, 20" I think. That was 10 minutes ago and I've forgotten already. Don't get old guys. Ignore the writing on the board.
-
If there is no hinge then it looks like a few more scrapes on the left limb?
-
Stiff in the middle on the right and a slight weak spot 10" from tip on the left. Best make that go away before it grows.
-
That kink in the left limb has been bugging me for days. It's been marked don't touch since first brace. I thought I had that fixed but I can see it now. I think I was just getting used to it.
Stiff in the middle on the right. I wouldn't have thought that. I guess that lump is scaring me away from that limb.
So both limbs need work in the middle? Left to correct the weak spot and right because its a little stiff?
-
the part you think is a hinge,, what is the wood thickness like there??? the right limb looks a tiny stiff,, but I see the reflex in the unbraced photo,, so dont think you are much off,, I see the weak spot Pearl mentions,, again ,, what is the thickness there compared to the rest of the wood,,,can you tell from the grain if it is thinner or thicker,, I think over all it is looking very nice :)
-
I ran over it with a gizmo and it was just like PD said. The part I thought was hinged is bent enough so the gizmo doesn't hit it but the wood is thick there so I think it's a natural bend. It was thin on the left tip and stiff in the right. I'm sneakin' up on it.
-
Next set. This just doesn't look right to me. It looks like the right limb is bending way too much. The gizmo says they're the same. I want to scrape a bunch on the left fade.
-
Looks like she is hinging on the right and stacking... I'll draw you a picture or send a photo on how I have been doing the tiller lately it works very well its quick simple and very effective. My second to the last bow I was 1/8" positive tiller dead on. :)
-
bow seems a lttle crooked on the tree,,, makes it hard to see the bend for me,, :)
-
It's in the same spot as the braced picture. The angle, at least to me, means that the left limb should be bending more. But what do I know, that's why I posted these pictures. I used Del's trick and held a CD up to the screen and the bends are fairly even. The top limb is longer, I did the one inch above center, three below for the handle. I think that if the left fade bent a bit more it would look better but whether it would actually "be" better is what I'm not sure of.
-
I agree, the throat of the handle looks like it is slanting in the drawn photo whereas in the prior two it looks level, which does look like it is tilting on the tree. Even looking at the photo with a cocked head though it looks like the right limb is bending more, but with the plumb tiller tree it is tough on the eyes.

i think there is more handle sticking out on the left,, in the drawn photo,,but sometimes photos are deceiving :) :)
-
The bow is free to rock on the tree so when it tilts more of the top shows. You'll notice the tips are even. :D
-
Wait a minute. You guys are right. Because it's symmetrical I had to put it in the middle of the handle to get it to balance to take the picture. Then I moved it to the center to pull it for the drawn picture. I usually center the bow on the tree but this time I thought I would try putting on the tree closer to how I hold it. A lot of people on here say that's the way to go.
-
Here is a picture with it centered on the handle. It doesn't look much different. The handle was pretty level before I pulled it.
-
Maybe see what she looks like in hand with an arrow nocked?
How does it feel when you pull on it?
-
OK I couldn't stand it. I lightened up the left(bottom) limb and got this. It's just over 40# at 27". I think I'm happy.
-
And like this on the tree. Bottom limb on the left
-
Interesting that one the tree the upper limb rocks forward and yet on your hand drawn pic the opposite is true. I think your two draws are a fair bit off and you need to figure out how to make the two more similar.

If you notice the side of the trailer,it's leaning toward me. I had to rotate the picture a bit to get the arrow level. I think I had the arrow nocked a little low. The camera was ticking, I didn't have much time. I've tried to think that through and that would mean I was pulling on the bottom limb more. My head is starting to hurt.

Do you mean I have to get my tree draw to be closer to my hand draw? Do you have any suggestions?
-
I never mess with tillering trees much, I rough to bow dimensions and bend it over my knee to feel which limb is stronger, and see what areas are already stiff or weak, then I put on a long string and head to the mirror and flex the limbs to see where the stiff or weak spots are. I then progress from there with the rest of the tillering process. I like this method as I know how the bow will feel in my hand very early on and can make adjustments for comfort or twist that I wouldn't see otherwise. (also i'm to lazy to make a tree).

The handle is not level. Did you pull the string at the exact same place? If you did the the left side is stiff. Take some off that side. Arvin
I dint see page two. Looks like you got it worked out. Good tiller. You and I share the big belly. Good form by the way. Arvin

looks good to me in your hand,, if it shoots well and you are happy,, and its not broke,, I would say you got it,, :)
