Thanks everyone, this bow taught me alot and is for sure a milestone for me personally.
Limbit- I have seen the spliced antler bow vid you speak of, of the bows in the local museum is a well known short spliced antler bow.
Its around 32", the core is made up of 3 or 4 pieces of antler, it looks like a thin backing of something, baleen maybe? With a sinew cable as well,
Beadman - Making sinew strings is something I've gotten pretty quick at, so its not as tedious as it once was. I actually find it pretty enjoyable and satisfying now.
RPS3 - From what Ive been told, its not illegal to have baleen if it has been cut up for craft purposes, or something like that.
