My horn bow build-a-long
DC:
Step?
I got a bit of shaping done today. Narrowed and thinned. I don't want to thin the sals until I've finished the kasans and tips so I've got something to hang on to in the vice. The horn is about 4mm thick, I hope that's right. The Book is kind of vague about how thick the various parts should be. It's hard to shape a bow like this when you've never seen one. Pictures just don't work that well if you only have a couple of views. I spent most of the day searching the net looking for pictures of the kasan, eye and tips. Are Groziers bows fairly good copies, most of the web pics are from his site?

Bit of a setback today. I was reducing the width of the tips. I had about 3/8" of wood to take off i couldn't reach it with the bandsaw because of the awkward shape so I thought I would use a hand saw. I got about an inch into the cut and realised that a rasp would be the better tool. I started rasping looking for the saw kerf to know when to stop. Never saw it go by :-[ :-[ :-[. So I epoxied a piece on to repair it. Once it's all shaped the piece will only be about 1/16" or less thick so I'm sure it won't be a problem.

I was looking at my trial core wondering if I can use it for a bow. It is flawless except for this knot. If I made the limb 24mm wide it would go right through the centre of the knot on the belly. Where it appeared on the back would depend on how much core I used. If I made it 22mm wide it would almost disappear except for a wiggle in the grain. The core is the same shape as the one I'm working on so a little heat would straighten out the kasan eye bend. You can see where it is by the handle "V" joint. What do you think? If this was any other bow I wouldn't think twice or even once about it. :D
DC:
Is this very roughly the shape I'm looking for at the tip/kasan bend? This is on the trial form.

The knot makes it completely unuseable. Don't kid yourself into thinking it will work - it won't! It isn't just the knot it is the swirly grain that accompanies it that is also a complete no-no! This is the wooden bow making experience talking! Go back to beginner status and just follow what the book says word for word ;) You need a different mindset making hornbows. Literally every single thing must be perfect....or else that house of cards starts wobbling.
Your shape is sort of right but you do not want the grooves on the belly at the base of the tip. The tip should be triangular and the string simply sits on the side of the triangle.
Yes a step from the width of the kasan into the width of the tip. Don't blend/fade this area make it a step down in width.
I'll try and get a good picture of the tip.
No Grozers aren't really what I would copy.
You can get many pictures from the bows in the Topaki Palace collection.
