Backed Flatbow Siyahs

[PatM]

That is just the  outside of a stave reduced  in thickness. It's hard to beat a single unbroken ring for a back.

PatM- This may be a dumb question so excuse my ignorance.
Is a spliced in siyah the same in performance as a static recurve of the same dimensions,
Or is there noticeable higher performance because a lighter wood can be used?
Aside from looking real cool, and being able to get longer bows from shorter staves, is there more advantages? Just a style preference?

[PatM]

You can't really compare them directly since they won't be the same dimensions.
 Studies have shown that  sharper statics store more energy but lower angled levers are more efficient. 
 Seems to work out about the same.
 You'll have to make one and see what advantages you find but better use of short staves and smoothness of draw are definitely pluses.

thanks pat

there are some good questions here, and some excellent answers.

this thread will get bookmarked for when my Siyahed project get started

  Yeah, Willie, I used to mess around a lot with recurves of all types looking for that perfect, secret, stiff but weightless, high energy storing recurve.  Styles are fun to mess with because they teach you things, and I have made some fast recurves, but basically, if I execute ANY style well, they all shoot about the same speed.  Maybe that is just me.  Go do it, it's fun and you'll make some cool bows.

  But, don't get me started on all the stuff I mean to do someday!     The hollow recurves. The cable-backed Arctic-style hinged recurves.  The linen-backed bamboo longbows.  The multi-pyramid loose laminate bows.  The double cable Mollie.    So many crazy ideas in my head.

  Does this just take forever, or do you have a cool method?

 I have a cool method involving a very sharp hatchet, a farriers rasp and a board with coarse sandpaper stuck to it.
 Doesn't take  that long with practice. The hard part is you basically sacrifice a perfect self stave to use only the outside 3/16.

Pat, I have a 40ish inch long piece of yew, is it realistic if I splice on syhias to reach a 28" draw?

[PatM]

 How clean is  it?

[Blaflair2]

It's perrt much perfect.

[Blaflair2]

It's japanese yew, so ring count isn't as high. Just dunno what to do with the little feller

[Springbuck]

  Cool, Pat.  That's how I used to do bamboo!  I think most of my elm is oo wayy to try it, but if I ever get a short, fat chunk, maybe I'll do this instead of billets and splicing.
