Joe,
Our shop recently "stitched" a 1904 Baldwin upright plate. It turned out =
beautiful. One thing about stitching, Vs welding, (we have done both) is =
it does work.
No fear of microscopic cracks developing due to the application of high =
heat. As far as cosmetics, a light grinding..you can apply some sort of =
resurfacing
material..bondo or primer..like most "good looking" plates have under =
gone, and end up with a quality job. Stitching is commonly used on =
diesel engine blocks
and heads etc. where the end result is a finely milled surface. You can =
not see the repair after the resurfacing. No bondo there. It is very =
simple to do, with , in
my opinion, superior results compared to welding. Just a couple of cents =
worth. ;-)

  Patrick,
  First, it seems to make better mechanical sense, to me. Second, I =
don't know
  of anyone who does "Stitching" in our area and none of the techs here =
have
  ever had a plate "Stitched", to the my knowledge. I prefer to go with =
a
  process that I know will work. Besides, "Stitching" requires some sort =
of
  "bondo" to cover the job, in order to make the job cosmetically ok. =
Whereas,
  with welding, filing and grinding, then primer, etc., looks better to =
my eye
  and makes me feel like I've done the job properly. Just one of my many
  quirks. <G>
