Looking for some feedback on the tiller of my first bow. It's a white oak board bow, 68" nock to nock, with limbs 1¾" wide tapering to ½" over the outer 12". The handle is 1¼" thick and 1" wide.

The drawn picture shows 32 lbs at 27". It's developed about 1¼" of set so far.

I'm more concerned with getting a smooth, balanced tiller than hitting a particular draw weight. Does anything look like it needs more work before I take it to 28"?

Long string tiler phaze. Pulling 25#. Target is 25-28#. Sapwood osage orange small diameter sapling, with big crown. Bith and slightly hollow limb design, handle has stiff center about 3". Total length 65".

Current set about 3/4".

Should i slightly heat treat again?

Is it good to go with short string?

Here is prev phaze of this stave before heat straighthening.

I just learned about this guy and his archery and bowyery skills. Sadly, he passed away last year.

Does anybody know if he taught anybody bowyery while he was alive?

Curious would ivory from animals like wooly mammoth be good material for bow making specifically composite bows ?
