Crimean tartar style horn bow build along
superdav95:
Update on this tartar bow…. I put the first layer of sinew on tonight. Followed Adams book instructions as best as I could interpret. Measured the bundles and then split those in two separate bundles for the first course. Did the first layer covering the bending section of the limbs then overlapped on the handle section. Will let this gel and firm up over over night then string it in to a little more reflex. I’m gonna do as Adam suggests and lay 80grams so 40grams per side. Gonna do three layers or courses of sinew letting each dry 2 weeks in between. So far the wood core is just a hair over 1/8” thick. The horn is rounded a little more to do later but is slightly thicker then core but pretty close. My aim is to have wood, horn and sinew all about same thickness in the end. For the grooving on the top of wood core I found what I consider to be the perfect solution. A jigsaw blade for laminate wood 20tpi. The teeth were perfect and straight triangles as opposed to others I saw. Happened to see these at Home Depot and figured why not try it. It worked very well. Flawlessly actually. Super sharp and very easy to get started straight by hand. Not that it super critical I guess but nonetheless I’m gonna use the courser 14tpi blade in this set to do the horn grooves in my next horn bow. Gonna make a tool handle to hold the blade. The nice thing about these is that they come already super sharp and ready to go. I made my own groover with a file and lots of patients but would have had straighter lines with one of these little blades I think.
Here’s a few update pics.
Thanks for looking. Cheers

So after about 6 days of letting first layer dry I’ve developed a slight more reflex curve on the right side. Is this something I need to worry about or tend to. Meaning should I scrape some horn off the opposite side to match the curves. Let me know what you all think. Maybe I’m overthinking it and just deal with it when I tiller. I’d be interested to know what you think.
Cheers

This is normally an inconsistancy in the core. Leave it alone until time to tiller!

Roger that. I’ll let her go then. Could it also be the inconsistency in horn? I remember when I glued the horn on one piece had more curve in it then the other when sizing. Either way one more week till next layer. Thanks for the input.
Cheers

the core is the stiffest part and is what gives the bow its shape.
Horn strips are normally easy to make the same thickness/taper.
Did you heat the horns before glue-up? Ideally they should be at 50 degs and therefore soft enough to conform to the core. Horn has quite a bit less stiffness than the core.
