It steam bent rather easily for me too.I heat tempered the steam bent parts with a heat gun after cool down and drying a day or so to set the bends.It is a diffuse pourus wood so it's glueing qualities should be very good.The reason Mike used it for a horn bow core.
Overall it still is a tempermental wood and when it blows it blows like said about being the same as red cedar in that regard.In otherwoords it can be sort of brittle.
I still have a very good functioning sinewed 64" black cherry bow.It was sinewed over it's sapwood that was smooth backed.Not to hijack your thread but here's the example.



I think 1 of the reasons it can be tempermental is because of it's rings.I chased a ring on a black cherry bow and this is what it looked like.It took a while.The ring was undulated with furrows/humps/and dips.Not good tension wise for an air backed bow and the reason why I think it should be backed with rawhide or sinew.
This is a different black cherry bow.


A D style bow long bow that has extra length is a perfect design for cherry.Extreme performance designs of shorter lengths do not work out too well using black cherry as a self bow or single backed bow.It either breaks or can chrysall on belly over time.
The finished bow shown is pushing the limits of black cherry already.
