Thanks for that. I read the old forum link too. I guess I was lucky with the Record 778 that I bought. I've never sharpened the iron any way but straight across, and it works fine, every time. I think the important part is that no part of the side of the iron protrudes beyond the body side of the plane. Also, I've never needed to shim the nicker. It worked fine right out of the box, and has continued to. I do store stuff carefully so it doesn't rust as you can see. I don't care about being able to look at a tool until I get ready to use it.
I use mine a lot when I'm making a short, or one single piece of molding to match something else. It's quicker for me to hog off most of the material with the rabbet plane, than being careful in setting up the tablesaw to cut the rabbets before moving to the hollows and rounds.
In the picture I linked to above, with the 778 in it, that's a wainscoting cap to replace about 7 feet that was missing in an 1828 house. I had cut the rabbets with the 778 on each side, started to cut the bead with a 55, but the 55 was not cutting well ( in either direction) as you can see by the chunks missing, so I finished the bead with hollows rather than taking time to sharpen the 55 cutter.
