Thanks for the comments.
To answer some of your questions...
1: Yes, the limbs are kind of twisted... as you can see from the first picture. The horn is naturally curved, so when i split it I had the choice of weather I wanted one limb to reflexed and the other to be deflexed, or one limb to curve right and one to the left.. which essentially lines the string up on center. Granted the 1st choice probably would have shot faster, but I would have had to introduce reflex into just one limb to make them match... so it went with choice number 2. Which worked out great.
2: The small horns at the tips are hollow and small... on a normal longbow i would say yes it is probably adding to the hand shock... but I overbuilt the handle area to off set that. This bow has less handshock than a hickory selfbow and shoots just as well if not better.
3: The guy behind the mask is not as scary as his costume... At the show we were at, he came back an hour later without his costume on asking about his bow.... I had no idea it was him for the first few minutes of the conversation. He got the armour from Ukraine and I am helping him try to get his character on the big screen. Still quite a few years away from that though.
4: The gemsbok horn is hollow... and after I filled it my draw weight was 40#... during the year this sat there, I did make another one that I never finished and I gave it to my uncle. I laminated the belly of the bow with hickory and dyed it black, this increased my draw weight to 57#. Tillering a "twisted bow" is a little tricky, but it is not that hard to get the draw weight you want.
I like the idea of making a penobscot with the other horns, I will fancy the idea for the next year or so.
Thanks again guys, if you have any other questions feel free to ask.
