I think the major adjustment for me, to get a good short bow I was satisfied with, was to allow a little more work on the inner limbs, and a little stiffer on the outer. This helps retain good string angle. Leaving a little extra width on the inner limb, and tapering agressively are the obvious implications of such a design. It is nerve wrecking at first, but like all projects once you see it nearly full draw on the tree a few times you begin to gain confidence. Reflexed staves will show lots of early draw weight, so estimate your full draw weight at closer to 2# per inch, versus the old standby 3#. Then you can always take weight at the end if you mis-estimate. And you can't bull-dawg the tillering, you need to finesse, proceed methodically, and listen to the stave as you progress. All standard bow building stuff. It's not for free, a short, heavy bow, but it's certainly doable. You need decent wood though, and I think HOB goes to great lenghts to explain this.
I'd be happy to post a couple of 58", 60# @ 28" examples if you want, for inspiration or whatever. They've been posted a miillion times, you may have already seen them.
Contact cement is the shitza for fixing books. You need something flexible, unlike super glue, typical glues. Can't count the school books I'ver repaired for my 12 yo. My HOB is is still in good shape. Ya'll must have been extree hard on yours.
