Egyptian Composite Bow
BowEd:
Yes.Good point by bownarra.I was the one who was wondering about the mass weight.
In retrospect how mass weight can affect a bow I have a black locust self bow [no sinew] that mass weighs 14.25 ounces 63" long stiff handled that pulls 54 pounds @ 28" that is a very efficient bow.Kinda like comparing apples to oranges I know but the relativity is still there putting the mass placement where it is most needed in self bows.
Cool bow you got there though.
I've rummaged through my buffalo and gemsbok horn slat collection and have come up with a pair of gemsbok horn slats that should do the trick for me to make such a style of bow.They are 29" long apiece and 1/8" thick 1" wide midlimb which will give me around 15 to 20 pounds of draw weight.
I've made around a dozen complex bows and will do my calculations to make such an Assyrian type bow in the future using the reflex forms I have here.I have plenty of sinew also.My goal will be to get around 50#'s @ 28".
PS.....A full draw picture of yor bow would be nice.
ecounter:
full draw coming promise. One thing I have no idea on, where can i source the proper maple for these composite bows. Im guessing a hardwood supply even with the proper grain running in the wood is not the place. Anybody have suggestions? Thanks in advance.
BowEd:
There are other woods out there to use like ironwood [hornbeam or hop hornbeam].They are diffuse pourus also.That's what I'll use this time around.If you use maple make sure it's hard maple.
Made them from very tight ringed hickory a number of times also with very good success.
ecounter:
full Draw or at least mine at this poundage
BowEd:
Thanks.Looks great I think,and also looks pretty stout for you too.Some pictures of them show a more rounded full draw [out of context comparison] but that is on account of not as much reflex induced in the working limbs on theirs I'm sure.
I was looking at my Ottoman Turkish horn bow book Adam wrote and I had a sheet of paper in the book showing the preperation of an Egyption complex composite put there by me some time ago.It looks to me like an extreme version both ways of deflex and reflex.It's a copy I printed from the atarn.org/islamic/egyption composite files some time ago.Thickness taper is rather extreme in the beginning from the handle then slows down to 1/4 the rate from midlimb to tips.Paralell width to midlimb then tapering to 3/5th's width of handle.
1 reason why bows such as these angular bows need to be braced fairly high to avoid inversion of the limbs after releasing.
