Steamed the handle area for 30 minutes, put some set back in it and left it clamped 12 hours. Set dropped to a half inch! Strung the bow and shot the bow about a dozen times.
Checked the set. Back to over two inches. Think I gained (lost) an eighth of an inch of set. Angry
I'll get a pic of this bows deflex tomorrow. Then I am going to heat treat the limbs.

Red oak lumber bow. It would be nice if that deflex was reflex.

Heat treated the limbs today. The bow is clamped down flat. I'll be happy with any improvement, but wiil be good with an inch less set.

Ya, I think you will struggle to get rid of set that way. Who knows though right? Either way I wouldn’t leave it to dry for 12 hours, pull it and expect it not to take set again. I would let it sit for awhile or maybe after 24-48 hours I would reinforce the steam bend with dry heat bending (better yet, tempering) while it’s still attached to the caul.

Your tiller seems quite good so if it were me I wouldn’t be afraid of tempering the limbs while it was clamped into reflex. Commonly people will let it sit for 3 days in neutral room humidity to let the moisture in the limb equalize throughout before pulling again after a good tempering.
