Hi there. I literally just started making knives. I have a friend who makes them professionally and it always fascinated me. I have been a woodworker for many years and have lots of woodworking projects to my name but metal always intimidated me. When I started reading about all the diy grinders people have made, my mind was made up. I had to build one. I only bought the motor and the wheels. I made the rest from scrap after teaching myself to weld. Amazingly, it runs and tracks and all the adjustments do what they're supposed to. I also have a forge built (minus the insulation) and the materials for a diy burner. I think the building of the tools was as exciting as their purpose. Anyway, I've made two blanks from mild steel just for practice and I figure I'm ready to finish the tools and start making some real blades. I hope I can do half as good as some of the ones I've seen here. Looking forward to picking all your brains and maybe helping out where I can. First question, I built a simple bevel jig after calculating the angle. When I test it on one of my mild steel practice blanks, it didn't seem to make a really straight line. It was kind of wavy. Is this indicating a problem with my platen or technique? I figured a jig would take the guesswork out of the process . Thanks for any thoughts in advance.
