Getting horn laminations from gemsbok horn.[Pics added]
BowEd:
Thanks Pat.I know your no stranger to posting build-a-longs.I don't doubt other glues can be used.I can just vouch for hide glue and smooth on epoxy.There really is a broad choice out there.One key thing to remember I think is to get the glue line thin without starving the joint dry.That's why sizing is so very important.Too thick a glue line and it becomes too brittle.Keep it flexible.
M-P:
Beadman, My horn bow experience is still limited, but I, too, have had successful bows with Hide Glue and Epoxy, so I'll second you on that. The one korean bow that delaminated on me delam'd at the horn / core interface but the glue showed no signs of cracks. It was a rather thick glue line ( as is typical of Korean bows) so I don't think sinew glue is very prone to cracking. Surface prep to remove all contaminates is (in my opinion) more important.

Yea M-P keeping things free of grease,oil,and dust is a must.My horn bow experience is limited too.Especially asiatic types anyway.After the horn and wood core is grooved before glue up I don't handle it without wearing cotton gloves and still resurface it fresh before glue up yet.

Yeah, I haven't always done that, but I'm starting to get real paranoid about the whole issue of clean faying surfaces. Ron
BowEd:
Just with the two bows I've prepared so far I didn't let much more than a day go by to avoid oxidation of the surface.After resurfacing it and after sizing it.I glue it together with the rope cinching tool.Do all of this with cotton gloves on.I think if it works out that if a person can't get to it right away you can wrap it in saran wrap possibly.You keep sizing it letting it dry between sizings till it looks like glass when it's dry.Usually at least 3 to 4 times.That can be done in an afternoon.
