I liked PrimitiveTim's tillering video idea, so I stole it (assuming I got it to work).

This is a private video, and I will take it down in a couple of days, but any advice would be appreciated. (Good advice especially!)
This bow is an Osage flatbow design, about 63" NTN, currently 55# @ 23"; target weight is 55#@26". Brace height is still about an inch low, and I am drawing to about 22" in the video. There is some light propeller twist and other funkiness and I am trying to proceed VERY carefully since I had a similar elm bow to this point over the summer, took a bit too much off the lower limb, developed chrysals, etc. - grrr. Width is 1 5/8" until a bit before midlimb (sort of a compromise between Torges layout and TBB for flatbow design). It started with a couple inches of reflex (heat induced) and seems to have lost an inch or inch and a half pretty evenly so far. I would like to sweat it but really want to make sure the limbs are bending evenly. The top one is mostly the one I wonder about; the bottom one looks good to me (although it is the funkiest). It seems to feel balanced when drawing, but I am still learning to feel tiller that way and don't totally trust myself.
Thanks in advance! I am eager to get this bow done so I can shoot it of course, and also so I can finally post something here.

Here are photos. The bottom limb is the kinkier one and is about 1.5" shorter. I still need to reduce the bottom tip and shape the nock.

Your video link isn't working, at least not for me.

Me neither

Oops. It opens for me from the Bows page, so I assumed it would work for everyone. I will try to figure out how that works...sorry!

OK, it should work now. Sorry - I was trying for a tiller check, not a video check!

Still not working

Pat, can you check it One More Time? Pretty pretty please?
-
OK, it working now. I think you need to get the outer portion of the upper limb to bend a little more.

Looks pretty darn good to me!

I will check out the outer portion of the upper limb tomorrow. There is a cluster on pin knots around there and I left it just a smidge thicker. Also, that area has a bit of propeller twist, and I think that makes it look flat. Thanks!

That's what I'm seeing to0
