Thought I'd share a tip that was shared with me. We only do whitetail deer skulls and one of the struggles is removing the bottom jaw. Someone posted this on Facebook so I borrowed his picture to share here. This is simply an 3" u bolt bolted near the edge of the workbench. I installed one of these and let me tell you it's a lifesaver. we've done about 60 skulls so far this year and man this little trick here makes removing the jaw bone easy. Hopefully this will help others.
