Now priming became an issue all of a sudden. Did we want it
primed for acrylic paint or for oil based paint? Up to this point,
I did not know there was a difference. I knew acrylic paint looked
better and stayed better, but also felt it was too expensive for
this big a job. We decided to go with the oil based paint primer.
Bad decision! As time went on, we realized that to go to this much
work, time, effort, and expense, the best was none too good. Well,
not much happened during the summer of 1993. We had steam shows to
go to, and work to be done, and we both got busy doing other
things. Time flew by and all of a sudden, it was fall.

While all this had been happening at home, Boilersmith had
modified their plans for the boiler, sent them to Toronto to
M.C.C.R. and had them approved. The stamped blueprints now in hand,
they could start to order steel, make pieces and put it all
together. One day, I got a call to bring the old boiler home since
they were through with it. The new boiler was well on its way, and
would be ready in a few weeks. Eventually, it was, and once again
we were off to Seaforth (about 100 miles away), to bring home the
shell of the new boiler. It was a pretty looking sight to behold.
It finally looked like one day we would have an engine put together
again.

Reassembly

In Ontario, when you do a boiler job such as this, it has to be
done in stages. That is to say, when the boiler first came to us,
it was only a shell no fire box, no stay bolts, no tubes, no flue
sheets – -just an outside shell, The reason for this is that after
marking, drilling, and tapping all the necessary holes, Ontario
Pressure Vessels Act requires a plug to be put on the inside a
piece of metal about one inch thick and approximately 1 inches in
diameter. Boiler smith would put this on the inside, before
completing the boiler.

We had to set every piece in place where it would eventually go,
before drilling or tapping any holes. The reason for the plugs was
that the studs that hold the castings to the boiler would not go
through into the water, as they used to when it was built
seventy-six years ago. That way there was no possibility of leaks.
These plugs were also drilled and tapped about
3/8 of the way through. The stud then would
be about one inch deep. We had to be very sure that each hole we
drilled was necessary and in exactly the right place. There would
certainly be no chance to move it afterwards. This means that the
gears all had to mesh exactly right and the engine had to be lined
up with everything else. This turned out to be a big job, because
there were no studs to hold anything while we put on the next
piece. We used clamps and chains and bolts in the stay bolt holes
with clamps to put it all together. Bim figured out how to do all
this. I am sure he sat up nights thinking this one through.
However, as time went on he got it all laid out on the new boiler.
I took some pictures of this and he did the work and the
improvising.
