Pick up a digital angle finder. $12-15 on eBay. It'll save you more than that in headaches. We can help get you set up
Awesome! Like previously mentioned once every thing is in front of you and you start. It’s a mountain of info, as you go through setting up, and start grinding. A few chains under your belt things start really clicking. You will be happy you have it. The grinder really made me realize how inconsistent my filing was. I love the consistency the grinder makes chains.
on the 451c i use the same wheel angles for different grinds and usually only move the arm adjustments as huskihl mentioned get a digital angle finder and setting up the grinder is a breeze
