16" not to draw weight yet still looking to even it out, tell me what you see please.

Left limb looks good. Right limb looks stiff on the inner half then almost a hinge then the bend looks good.
Is this on a long string or braced?
-
What width profile does it have? Can't really comment until I know that.
-
Nobody should comment, on any bow, until we see pictures of their unbraced side and front profiles, imo. Maybe the limb on the right kind of started out like that. We currently have no way of knowing.
-
It is pyramid, straight taper to 1/4" tips. Unbraced is dead flat both limbs. Long string hanging down about an inch under handle.
-
I'm no expert but I would put an x on this spot and don't touch it for a while.

Look up the tillering gizmo some use on here. With a dead strait limb bow, the gizmo would make it so easy to tiller. Or use any strait edge 5 or 6 in long and run it on the belly of the bow. Start at the tip to the fades. Pay attention to the gap in between the middle of the strait edge and the belly as you move it along you can see as the gap gets bigger and smaller. The smaller gaps are where you have to remove more. Hope this makes sence and helps

I'd probably put it on a low brace, the short string will highlight any issues really quickly. +1 on the straight edge
-
Make sure you place it on the tiller and place the hook where you actually will hold it while shooting. Unless you intend to shoot like Ishi did.
-
+1 on the gizmo. I made 2. 1, 6” long and 1, 4” long for smaller areas I’m questioning on dead flat limbs like yours.
-
I agree with Pat about how it's held and drawn, which is another reason I don't comment on most tiller threads, at least not in regard to limb strengths.
-
Getting to low brace, like stuckinthemud said will tell you a lot about your tiller and your string alignment.
No matter what the back profile is, a hinge is a hinge!
-

Since it's a pyramid your limbs should be pretty close to constant thickness. Can you run your fingers down them and feel any thin spots? I agree with the others that you should be very careful around that right limb, I see a hinge in progress as well. For a pyramid the tillering gizmo will work great for fine tuning the bend.

Agreed Pat B I don't want any hinges. Will a tillering gizmo help me develope a better eye for tiller, the main reason I haven't made one is I don't want to stunt my growth.
-
Anything that will help you achieve good tiller will help you develop a better eye for tillering. The tillering Gizmo is an incredible tool, not a crutch. Use it well and enjoy the results.
-
I agree low brace will be more revealing on the tiller,
-
Ok pat I'll make one. Brad can I low brace now without hurting the bow?
-

It will let you fix problems you can't see yet and produce a better bow. I would say it is good for your eye because it will highlight problem areas that you can then look at and try to see what is going on while they are still very slight.

what is weight on long string,, if its reasonable weight, you can brace,,
-
That is true mark. Brad it is 44lbs at 16" on the long string
-
It will, it is hard to train your eye to look for proper tiller if you haven't seen much of it.
The gizmo is just another tool to make sure you are not missing anything on your limbs while you tiller.
I have an artists eye and can see very small anomalies in a bow tiller, I wasn't always this way but learned over time, the gizmo trained me.
I could tiller without it, but why, it greatly speeds up the process, prevents hinges, low poundage from chasing tiller up and down the limbs and generally has you coming in over poundage so you have a lot of room for fine tuning the tiller.

I'll give it a whirl Eric my only concern was handicapping myself but everyone is in agreement that it only helps. I'll make one up soon

Since you are making a new one, I would suggest also incorporating PatB's center finder arrangement on the back side of the gizmo. If you plan to work on staves it is a very helpful addition.

Mark I intend to do that as well : ) I think it'll be a great addition to the tool
-
This is after a tiller session today using Eric's gizmo.

Does anyone see a little more set in the left limb?
-
I do for sure. That was the weak limb for most of the tillering and it had the closest thing to a hinge. It was dead straight before I started working it
-
Let the set dictate where you need to tiller. The set is telling you that the limb on the left is weaker, and starting to hinge 1/3 from the tip.
-
I was afraid to take off too much wood so I don't think I worked around that hinge fast enough
-
is it braced yet,, maybe take a little more off before you string it,,
-
It was braced about 3" from the belly of the handle Brad.
-
I think its looking good,, proceed with patience and post lots of photos,,
-
Hopefully I get to work on it tonight. Felt good to make some progress. Time flew while I was working
