[Farmall] Welding cast iron

[Chris Klossner]

  For attaching the steel ears to the cast brazing would work well. It
would also be the easiest to finish.  One would have to heat it up about
the same either way to weld it or to braze.  The property you  refereed
to cracking behind the weld is more of a heating problem.  When cast
iron cools slowly the carbon forms graphite between the iron which locks
together making cast iron some what rigid. Graphite is soft though and
does have some give to it.  When cast is cooled rapidly the graphite
does not have time to form. The result is cementite which is a much
harder form of carbon. By this process  the chilled iron plow shares
were made. Giving them a hard wearing surface.  A 12" monarch is a nice
size machine. More capacity than the modern equivalent size. The 30 I
have is a 1940's Witcomb. It is a little big for most every day things.
I also have a 42" LeBlonde and it is mostly for steam engine gearing and
clutch repairs or occasional flywheel.
