So I’ve got a nice 50” peice of hickory and I would like to make it into a little recurve for one of the kids down the street. Not looking for much in draw weight. Anyways I want to recurve it but I’m not wanting an overly severe recurve. Maybe put some reflex in there in the handle area make it a 5 curve. The kids got a short draw length of maybe 20-22”. Any advice. I used dry heat last time to recurve it and almost cracked the wood so would steam be a better choice?

i would steam it. then heat treat the bow. then go from there.

I figured that might be a better choice. Cracked the tip on a 60” stave of hickory using dry heat and and had to shorten it. I was not a happy camper

Soak and boil is best but steam can work well too.

I just did a few sharp recurves in hickory billets and they are a real pain compared to Osage. I boiled for an hour and a half and they still cracked. Next time I am going to soak the tips for a day or three before I boil and bend them. Good luck 👍🏻

I have tried both dry heat and boiling in the last month.....the dry heat was not successful and I only achieved a small "flip" of the tips and had real issues with cracking.
Last week, I put some ~60 degree recurves in the tips of a 62" stave that was just over a half inch thick where I bent it. I had some very minor surface cracking, but nothing unexpected and it went better than I was anticipating. I boiled the tips for an hour in a large stock pot covered with foil and then bent them ASAP on my jig with a sheet metal strap over the belly, which appeared to be effective at preventing splinters. I definitely wouldn't go less than an hour on a half inch thickness though. It definitely was not as flexible as osage would have been with similar treatment.

It's definitely consistently possible as I've done it many times with hickory steaming them up to 70 degree recurves at 9/16" thick on a pot on the stove.Proper prep of rounding corners on belly is a must to do.Soaking in water prior good idea too but I've never needed to,nor have I needed any type strap to prevent splinters.After cooling off and drying out I heat temper them with heat gun and lock it in.
an example on hickory at around 50 to 60 degree.Go for it and good luck.

I like your caul Ed. I have one similar but I like how you have two and different curves on each end of them. Very versatile.

PS sorry can’t help you with the hickory, but I do like Ed for HHB only I do use a thin metal backer.

I have many recurve cauls BJ with identical narrower matching ones to dry heat treat lock in the steamed in curve avoiding any burning of the backs of recurves.Along with a bunch of full length cauls of different designs.

The possibilities are enormous Ed. I like it.

I guess but the proper preperations are the same for success.

Ed those are badass, and you sir are awesome.
