I don't have the smoother, but I do have the low angle block plane, which
also has an adjustable mouth. It isn't a gimmick at all, and makes
adjusting the plane very easy. I'm no plane expert, but I've gotten bit by
the bug and have only in the last few months purchased a Clifton #6 (on sale
at Woodcraft, too good a deal to pass up) and a load of eBay Stanley's (a
#3, 2 #4's, #5, #5 1/4 and a #7). I also have a Knight coffin smoother and
Knight razee jack plane. I'm also getting the Veritas scraper plane for
Christmas, DAMHIKT :).
Anyway, my point is, on the bedrock style planes, you have to set the frog
properly to fully set the mouth width. Again, I might not be using the
correct terminology here, but hopefully you'll see what I'm saying. When
you adjust the iron to the depth you want, if the mouth opening isn't the
way you want, then you have to readjust the frog - which isn't hard, but
it's just one more thing to do. On the Veritas block plane I have, you just
open the mouth all the way, set the blade depth how you want, then move the
mouth to the opening you want. It's a great thing, really.
There are no stupid questions.
There are a LOT of inquisitive idiots.
