This is a fair comment if you're intending to use the plane a couple of times. I put in the time commentary because I'm setting this plane up once, and more from maker's fascination will track how much it moves. It probably won't move much.PS I had a look at the Nelson plane thread. If I was desperate enough to want to use it wouldn't have bothered with all that flattening of the pitted edge I would
The amount of time I spent on the iron, an extra two or three minutes to work most of the pitting out, will be recovered in a half dozen sharpening sessions and length of time between sharpenings. The illustration of that in five minutes is also a matter of "I need to take a shortcut" reasoning vs. "I need to buy a special stone for this". No, a $20 glass shelf and $2 worth of PSA roll will do this, but it'll do several dozen chisels before I need to change it, and a bunch of other things.
And there's no reason to come up short. What you don't see beforehand is deep pitting right in the apex and on the bevel side (which needed to be squared to set to the cap iron - i wouldn't do it if it didn't need it). The reality is you would have spent more time than I did in both of these - on the bevel side, needing to take a couple of hundredths off of the iron (Which is a LOT) was aided by a ceramic belt grinder. total time on all of it was about 10 minutes. It's good for life now and will plane anything without ever clogging.
All of these little bits are easily glossed over as "that's rabbit hole". it's bad advice. A better question is how can I do that well and quickly and only once. Shortcut applies if the answer to that question is "you can't, you can shortcut quickly or take a long time".
You couldn't have ground the pitting out of this iron and squared it in ten minutes by hand, let alone had it sharp (add about 3 minutes to the 10 above for finishing the job after flattening and correcting the bevel and setting the cap edge).
