I did some processing of the Bison bones. Step one is to cut it into smaller pieces, then into the slow cooker to boil off the meat residue and some of the marrow. After a good number of hours I cut it down into smaller pieces and boil out what is left.

After it dries I cut it down into even more manageable pieces. Now I study these pieces to see how to best further process them.

And this is the result. I have many more pieces that I can cut out of my bone supply, but for now I will content myself to my present needs of one tie block cap, one saddle, and one nut.
