My horn bow build-a-long
DC:
Thanks bownarra I wouldn't be this far along without your help, much appreciated :D
I tried a search for the Topkapi Palace collection but I'm not having any luck finding pictures of bows. Do you have a link that might get me there?
I'll continue using the knotty core for practice. So the kasan should be a sort of triangle with the point to the back and the tip should be a triangle with the point to the belly. JWB bows has a short video about carving this. He scoops the sides of the kasan. I read somewhere that this isn't necessary on a light bow. I would have thought that it would be preferable on a light bow to bring the tip weight down. What's your opinion on this?
Thanks again
Don

Here is couple of pictures i took just couple of weeks ago. These are from Istanbul military museum, topkapi didn't have these angles to take pictures from. Actually its prohibited to film there but...
If you google "mandarinmansion turkish bow" you will find Peter Dekker's page that has a lot of close up pictures of good turkish bows.

Thanks JNystrom I'll take a look.
I have more questions. This will be my last chance to get the horn to an even thickness. Is anyone willing to take a shot at horn and wood thickness for a 40-45# bow. the bow is 120 cm NTN, tip is 8 cm, kasan is 20 cm measured at the apex of the eye bend. Limbs are 24mm wide. At the moment the horn is about 4 mm thick. I think it should be closer to 3 mm but I don't know. I'm wondering if I shouldn't make the wood a bit on the thin side as I can reduce the horn on an assembled bow but I won't be able to get to the wood. The Book says the 3 parts should be about equal thickness which would put the sinew at 2 mm but The Book says I should go with 3 mm. Again, I can reduce the sinew if there is too much. Is it possible to reduce the draw weight on a completed bow? I'm concerned that this thing is going to be too heavy and be totally useless to me.

The ONLY help I can offer is to take it off your hands if it comes in overweight. :)
I have always enjoyed your posts and craftsmanship, so I'm looking forward to seeing this progress to completion.

So am I but boy it's tough at times. I've been close to packing it in at times just from the difficulty in finding out stuff. If it hadn't been for writing this build-a-long, I don't know. I've started reading so many of these things and have them fizzle out to nothing I vowed I would see this through make or break. I actually don't think the building is that tough, we'll see, but knowing what to do next is hard. The Book is supposed to have everything but it's buried. Once you figure out what to do all of a sudden it appears in The Book.
Sorry, Rant mode off. ;D ;D
