Nice one!
I have a hickory Sugpiaq style that has been sitting in the corner for a while, I have no idea how to start and run the cableing. Any tips you could send my way would be appreciated. I was thinking about using artificial sinew.
In my experiance, Artificial sinew is a PITA to make a cable out of cause its so slippery. you can't tie a knot in it.
Try nylon:) It works really, really well, and is MUCH cheaper.
for mason line, just wind from nock to nock 6 times(so 12 strands), carefully remove and whip the ends (serve it like a super thick bowstring)... if the back isn't too crowned just tie it into place a few times. If its really crowned... have fun.
Here are some links-

Primitive ways tells how to do it, slinging . org simply talks about it.
I will take some pics once I am back from vacation.
