I've read numerous threads on this forum but this is my first post!
I am sharpening the irons for three planes which I recently acquired. These are all Stanley Type 13 with Sweetheart irons. Right now I am working at getting a primary bevel using a diamond plate and a honing guide. All of the irons have issues:
Iron for my No. 6 - The primary bevel is about 15 degrees. I've changed about half of the bevel to 25 degrees, but would have to shorten the iron about 1/8" to get the entire primary bevel to 25 degrees. I have a similar problem with a No. 5 iron that must have been sharpened by hand on a bench grinder and has a "primary radius" in lieu of a bevel. Should I leave it where it is now, or correct the entire primary bevel? (This photo may be from the No. 5)

Iron for my No. 7 - This one was looking really good. It didn't take a lot of work to get a 25 degree primary bevel and the cutting edge is square to the long edge. But when I was comparing it against the iron from the No. 6 I found that the iron is bent. It has a bend about 4-1/2" from the cutting edge and is bent at about a 3 degree angle. I put the iron back in the plane and now I see that the iron does not fully contact the frog. Can this iron be straightened?
