Wanting to start a Crimean tartar horn bow

[Mafort]

Sooo I’m wanting to start my first composite bow. I’m wanting to go with a tartar style however I am absolutely lost with where to start. I’ve got hickory or maple for the core and I was thinking I’d use black walnut for the siyahs. However I’m not sure what the lengths of the limbs or the siyahs or anything else. Can anyone help?

I'm definitely no expert on this style but I think they would have been in the range of 54 inches long.
Best to make the core 5 piece.
Keep the width at around 1 3/4" of all core limb parts when splicing together.
Handle section 12  - 14" 4 - 5" inch splice into the bending limbs.
Make these around 14" long. The kasans around 8 inches and tips around 3.
Angles should be taken from an old bow.
Once you have the core assembled and horn glued I can help with limb widths.

Here is link my friend Jano wanted me to give you:

Actually these are the same dimensions i tried to base my own crimean tatar. It failed miserably though, but not because of the measurements. I'll attach my translation of those measurements here.

Btw, what i found out was that its pretty hard to make a stable highly reflexed long hornbow (50"+). If you are aiming for lower draw weight, under 70 pounds, i would suggest making a shorter bow. I thought my bow was a bit wobbly, it might have ended somewhere 60-70 pounds of draw if the horn had not delaminated. Well anyway, good luck!

Also i have some angle measurements from gluemont . Some people might know him by a name Beaumont. I'll attach them here.
