Looking for some help/suggestions please.
Measuring from the center of the bow to equal distances on the fades, the bow shows dead even tiller.
At first I put it on the tree with a pivot point exact center of the bow and pulled straight line approximately 3/4" higher(estimated center of middle finger shooting split). The bow immediately tipped toward lower limb and kept that track with nocking point riding about 1/2 off of the perpendicular draw line. At full draw the tip of the lower limb ended up about 1-1/2" behind the upper tip.
Then I decided to block the riser level so that it could not pivot. This time the nocking point traveled perfectly down the perpendicular line and both limb tips were dead even.
What should I do? Anything? Nothing?

Forgot to mention. I would like to shave 2-3# off the draw weight. I hit just a little over my target weight.

Your tillering looks dead on.

I'd shoot it some more, looks good. It may tell you by nock height or vibration or noise if it needs some more work. You can trap 4# off real easy , or if you haven't rounded the corners off that will take some off!
-
You always have to level the handle in the tree cradle. I leave the handle grip area flat till I'm finished with the tiller. It looks pretty good.
-
I agree with Roy. If you are measuring your tips and how far they move relative to a level line, your cradle and handle need to be spot on level. 1 degree off of level in your handle area equals over 1" difference between your tips (assuming they were straight to begin with).
-
So It looks like you are good. Once you leveled your riser with your cradle it tracked well, the tips were bending evenly, and your tiller looks good. I'm not a tillering guru, but I would be happy with that. I would forget about what was happening in that 1st picture.

Also good to me. I find aggressive corner round will get you 4 lbs.

Thanks for the help guys!!
I flattened the corners on the back of the limbs and rerounded them. Managed to drop about two pounds.
Put the bow back on the tree and with the weight of the scale hanging on it I leveled the riser with the block. Everything seems to be pulling nice and straight and limbs tips are coming around nice and even.
I know it's a glass bow and shouldn't require much tillering. But if it's worth building it's worth doing the best I can.
Well I guess I'm ready to start final sanding and get this thing ready for a finish.
Thanks again guys!!!!

Yep... I guess that separates the novice from the fine craftsman...
Good Job Bvas...
