"Obviously lack of experience is the problem but I think need to make a good bevel jig. I used a crappy jig I made and clamped with a vice grip."
I do not want to rain on the parade. But, a jig, no matter how good/bad may not be the answer to good crisp bevel lines.
To be honest, the pictures show a fairly decent first attempt. It is not perfect. I still think it is a pretty good start.
Does the bevel come close to matching on each side? The plunge line looks fairly even in the picture.
If so, heat treat and work the bevel once the blade is hardened. You may have better luck getting a crisper bevel line because you cannot take as much material off at a time. Nothing beats hand finishing for a crisper bevel line. In short, you are getting there.
Seriously. Keep going, it is looking good for your first attempt.
