Paul Sellars is a guru, no doubt. For us mortals, using a plane iron jig with the scary sharp system gives good results. And, make certain to FLATTEN / deburr the back side of the blade. One side does not equal sharp.

(Link was way too big to post)

What Paul didn't say, is that the sole / sides of the plane should be cleaned up. Most of the planes for sale will be ancient, rusty and in poor shape. Even in so, the oldies are better than the $20 new planes. Those are just awful.

True the plane up on emery cloth glued to a flat piece of granite or steel. Replace the iron (blade) if worn out. And then you can pretend to be Paul Sellars!!!
