Hop horn beam and belly frets
George Tsoukalas:
I have never had a bow with high MC fret or chrysal.
If the frets are spread out over a large area of the limbs then it is a design issue ...too narrow or too short.
If the frets are localized to smaller areas then the tiller is off...too much bending there.
Hard to tell about tiller without photos.
Just because the tiller "looks" good doesn't mean it is a good tiller for the stave.

George like Dave said to much moisture with heavy belly heat treat with this wood may be counter productive. Maybe design to, but I don't think so. I have made many bows with my technique , including black locust, and many white woods, and never have fret problems any more including white birch, and walnut. Brad, the log is pretty straight, and was long enough to get 7 staves at 62 inches in length. 5 inch non working riser with 2 inch fades. The outer white wood varies in thickness from end to end ,and when finished their is some heart wood on the belly. I don't know if this is common with this wood, or not. First time working with Hop hornbeam , so it may be a learning curve for me. I have more staves, so I will get it right eventually. I wanted some insight from those of you who are well versed with this wood. Thanks again for your trouble shooting tips. I will keep them all in mind. This try will be a flat bow design with a trapped back, and some other method mods.
BowEd:
+1 of what George said.If the tiller is good before heat treating it should stay ok with no issues.That's all depending on the character of the bow also.Overly charaterish bows can be more susceptible.
I personally don't like heat treating bows with a lot of knots in them.
George Tsoukalas:
Batman, frets go across the grain on the belly side.
If the wood is too wet when heat treating that will cause drying cracks which are almost always with the grain.
Don't ask why I know so much about chrysals and frets. :)
