After getting the urge to just do it, I figured out a way to mount the engraver. Here (https://drive.google.com/open?id=1_LojTisBF6KcovdYOViW8rlrsONOxy7l) I've added a picture of my method. I use an SVS-38 and made sure the screw bites down hard. This part is fairly tricky. I then set up the angle guide against the back edge. I first grind the large face at 45°, which goes very quickly as you can imagine. Then, I rotate the piece to address the heel. I had to lower the support bar almost to the wheel as well as push the piece to the edge of the jig in order to make it a low enough angle. These sides went even faster; only about a second on the wheel. And that was it; I tested it immediately after and it worked great.
