The iron was better off than it looked in the dim light when I got the plane out of the box. took a total of about 25 minutes to prepare this plane (to be fair, I have gotten better at doing that now that I know what makes them work well rather than just poring over everything on a plane for hours).
I use a 42 inch lap that I've checked to be flat to less than 1.5 thousandths over a 24 inch stretch (using a new starrett straight edge). It stays flat as long as it's supported. 80 grit psa roll on all planes, but anything bigger than a 5 I will put the plane on the lap and then put it upside down in a vise and work the high spots sectionally because they just aren't easy to lap quickly and too much lapping will make the toe and heel proud more than I want.
This plane, however, I did not have to work sectionally. It is the flattest vintage jointer I have ever come across, and it came into the condition shown within 10 minutes and not even the slightest glaze of sweat. I left a high spot to the right of the mouth, it'll never factor in anything, and I didn't try to brighten the sole all the way to the toe, it would just reduce the flatness to do that and waste time.
These rolls of paper are available on amazon here for $11 (They are porter cable brand) and I like mirka gold a little better, but it costs a lot more than that. It works out to the paper on the lap costing me a little over a dollar. With a 7, the paper has to be fresh even if you're just finishing up a job where you worked high spots off sectionally. The paper is close to the edge of the lap because I use it then to flatten the iron initially, and then after this, only about two more minutes of work on a 400 atoma and then a washita. There is no need to overdo the work on the back of an iron, it makes no difference in finish brightness unless the edge has bigger problems from something else - the bright finish board I showed in another post was worked the same way).
I worked the bevel side with a diamond hone to set a primary bevel, cleaned up the cap on this lap and then with the same progression of diamond hone and then washita, and then 6 strokes on a horse butt leather with a sparing amount of dursol on it on the bevel, and planed the ash shown (into the grain) thick and thin shavings. No problem at all.
I have had a lot of vintage jointers, probably 10 (good ones, not junkers). This one is as good as the best of the rest that I've had (the other best one was a WWII era stanley that just happened to be about perfect).
