[TheForge] Woodwright's shop

[Bruce Freeman]

Walt,

That was my immediate thought - that the processes were dictated by the
material (wrought iron).  

I have no experience with the stuff myself, but I've talked with others
that have and I've read about it.   Apparently, slitting and drifting is
not the best choice with wrought.  Folding and welding, however, is
fine, and the drifting at that point is essentially like drawing out the
original material.

I didn't quite catch the process you describe for the other piece.

I saw a new episode of the Woodwright's shop yesterday - at least one I
had
not seen before.  Roy was at the Williamsburg BS shop where they made
a
"drop catch" shutter dog rather than the common pivoting dog.  
 
This piece required drawing, upsetting, welding, and drifting.  A real
interesting item and process.  It consisted of a drive pin, about 5/8"
dia.
to go into the masonry wall with a lengthwise slit of about 3" in it
for
another piece to fit through.  This second piece was the catch that
pivoted
in the lengthwise direction through that slot.
 
The process they used was different than most of us probably would
have
done.  Instead of slitting the piece, they welded a loop which they
then
drifted with a thin, wide drift.  For the catch, they flattened a
section of
a piece, put half fullered "notch" in that area, then bent the flat
around
and welded it to form a corner.  ...Hard to describe.
 
I've not done any wrought, but I wonder how much of this process was
required because they were working with wrought iron rather than steel.
