What you mean by "reduced the mass weight considerably"? I'm not an experienced shooter but to me it seems to be drawing very smooth for the given draweight. accurracy is good and the arrows seem considerably faster than what I'm used to with wooden bows. I havent done fd flight shots now but im sure it will top my wooden bows easily. top limb is glued with casting resin lower with ready to use canadian fish glue. Really hope it will last long and not blow up!
I havent got that pictures anymore nor the link. Its on the forum here somewhere, could be 2018. You also showed the reflexed core before glueing horn. I thought it was elm. Had a very long horn strip (gemsbk?) but shorter levers.
BowEd:
Ha Ha...yea I mean just that.The overall mass weight of your bow is very low for it's poundage and draw length and weight according to Steve Gardners mass weight theory.What kind of horn did you use on yours?Sweet looking full draw profile.
OK that one was 60" long and hickory again.With 8" levers.That one ended up around the same mass weight but @48#'s.Least that's the last time I checked it.Those two bows show around 2" of soft set after 8 hours of bracing and shooting.Returning to original reflex in a neutrally warm area in a couple of days.I believe your bow is working in a shorter working area on each limb than mine @ 8" per limb.Mine are working around a 12" length on each limb.They clock pretty good through the chrono and decent on the flight range but I think they should do better.
Were you the fella who asked how I glued the horn up onto the fades?I showed a curved chunk of leather padded wood.I remember now.
You can bet your last dollar it'll shoot better than your self bows.

before i took down again the first two (waterbuffalo)horns and thinned the core it pulled 42# @ 18" and felt like its just gonna blow up anytime. i tillered the horn down, took sinew down, hinged it, broke the core a little where i removed too much sinew - pure stupidity. fixed the core, put new horns on. put a fresh layer of sinew on the back. then: bracing it, one horn strip comes off...seems to be somehow too cold in the shop for proper glueing. i was annoyed then and took the resin and some suspect horn strip for a last try.... >:( (-S
BowEd:
Yikes....You earned this one.Congratulations!!!!You did your steps properly.Enjoy....and in time you'll trust it more and more.I used smooth on epoxy,but believe hide glue would work good too but needs more pressure wrapping than epoxy I think.Anyway I think I'll use smooth on again anyway.The thickness taper has to be spot on.
I found out to make more it's all about the thickness and width of limbs estimating draw weight during construction of more bows like that.Bownarra helped out with that too.Referring to those I had made that are finished and constructing them very close to that.Chances are your next will go a lot smoother.
The thicker the horn and the more the reflex the more instability it may have in the beginning,but it'll take less set then too.A person has to be a lot more patient tillering these than anything else.Dividing the core as around 40 or even 50 percent of total thickness with the rest of percentage divided evenly helps it be more stable.Does'nt seem to hurt performance any either.
I doubt very much these kind of bows will explode on you if glueing is done properly.Although I'm sure someone will have a case that's different of a bad experience but then something else I'm sure was drastically wrong along the way of constructon.Rather they sort of crumble and give in showing out of tiller before breaking.
Personally the only wood I'm afraid of just plain blowing up on me after torturing it on the tillerng tree is my local red cedar.It's dangerous....Ha Ha.Unless it's backed good.I've had some memorable explosions on the tillering tree with that stuff.
I broke a beaut of a horn bow a few months ago that was a dandy and already a bow.I waited over a year to tiller that one.It was 60" long and pulling 48#'s @ 28" and I barely removed 80 grains of horn to get it that way.I was shooting it in.I had my taper really close to spot on with that one.Mass weight was spot on too.Had around 300 arrows through it.It was settling in fantastic.With 14" of resting reflex and shooting at 12" of reflex after 6 hours.I broke it stringing it up on the peg board.Totally my fault.
More than likely I'll get around to making another.Got some more hickory and ironwood and plenty of horn and sinew.
simk:
Yup, blood sweat and tears. Still I enjoyed the build until the glue failure...
Yup, basically all you need is a good caliper and a few grains of black magic ;D it really helps to do a good documentation about thicknesses during the build. Its all about thicknesses, right.
I'd die for a nice piece of that juniper.
Sorry for your loss. How can you brake one on the peg? Did it a flip?
I parallel started a backup one - its ash - lets see if I get lucky again :BB
Cheers
By the way - I wouldn't use that heavy honeysuckle for hornbow - better show us one hld type bow. it only ads mass to the bending zone. And also for stability of the levers it might be better to have a more voluminous wood.
