Egyptian composite build a-long

Ummm popcorn . ;D
Phil I'm sure if I can do it , you can too.
Today I radiused over the back ,sinew side of the core .I will round over the belly (horn side ) after attaching the horn.
In this next photo you can see the red oak handle piece I added ,and the grain following the deflex in the handle.
To bad that will all be covered up .
I also started sizing the horn with thinned hide glue .A couple of these pieces didn't soak in the milk ,and they are reacting to the glue differently.
I will keep applying thin coats of glue and letting them dry until the horns don't absorb it any more and I have a thin coat of glue on the surface of the horns .

radius:
so, after a month of milk, are the pieces of horn...flexible? soft? or what?
welch2:
Both , pretty much just like boiled horns .But boiled horns get stiff quickly as they cool. The soaked horns get stiff as they dry. And as mentioned earlier , if you heat the soaked horn a bit (in the milk or hide glue) it gets even more flexible .You can hold one end and it will flop over like a wet noodle.
The previously soaked horns, when I sized them with thin hide glue , soaked it right in .And the horns that were just sanded flat the glue kinda sat on the surface for a while ,it took three wettings with thin glue for it to seep in . You can see it in the above picture , The top and the third from the top horn strips are strips of horn that were soaked in milk .Notice how smooth and evenly wet they look . The other two horn strips in the picture are just sanded . If you look you can see puddling and dry spots ,were the wet glue has already pooled around like water on a counter top.
I didn't have any boiled horn to try this time . Horn doesn't like to be glued . But I think the process of soaking them helps in this regard .

Knocker:
Thanks for demonstrating this Ralph. How tough is it to find the horn? Expensive?

welch2:
Keith , Gemsbok or orynx horn is relatively easy to find online and inexpensive . Around $20 each . You need to find horns that are straight in at least one plane ,and about 10" longer than you need. After sawing it in two ,you will have two pieces enough for one bow. The tips are very narrow so you loose some there ,and the bases are thin and brittle ,some loss there too.
Ok , this morning I sized the core ,took 2 coats .I also fixed a small spot where the glue joint between hickory and lemonwood was wider than everywhere else . I wet the spot ,heated it with a hair dryer .Then applied more glue and clamped it.
