Got to spend some time on this motor.
The first repair I needed attempt was to make
the mounts for the coil cover. The two on the
cylinders took some time but went pretty well.
.
Getting the broken bolt out of the mount to the
block, not so much. I spent as much time on
it as I did making the ones for the cylinders
and still failed.
First I tried a left-handed drill bit. Of coarse
the bit always moves off center for me.
Then an easy out. Last resort – drill & tap.
What’s left seem to be well attached.
As my hole was off center its probably best
that what’s left didn’t come out. I’m leaving it.
No wings for Clarence this time Bob.

Tubs, your weld job turned out pretty nice.
What rod do you use to weld on cast iron?I’m currently working on my grandpa’s AC, 1945 Lincoln welder,
which hasn’t worked right for several years.
I welded something cast with it years ago, and think I
had rod with some nickel content in it.
In the 50’s, when I was first getting into fixing and
making stuff, those Lincoln 225 stick welders, like
grandpas, were everywhere. Every gas station had
one. They still sell them. They look the same on the
outside. I wonder how much they stayed the same
on the inside.

I went through a lot of you tube videos
about welding cast iron. Had to sift through
the ones that are just useless bla bla bla.
Uncle Toni got right to providing information
so I listened for a bit to see where he was going
to go. When he said this video was not about
repairing cast iron, but welding to cast iron, he
had my attention. His advice at 10:00 in his
video was what I was looking for. While he
was using flux core, I used a mig, steel wire,
75% Argon-25% Co2.

Lots of good info in Toni’s video. He gets right to
and stays on topic.

Cant suggest a good video. The way I do it is not considered the proper
method – which is consent with much of what I do. The topic
should bring some life to the board though.

Still have more parts to repair before they will be
usable but plan to use the motor next summer.
If your question is about this picture, that’s a piece
of copper tubing to keep the hole open. The steel
weld won’t stick to copper. I built up the weld a
little at a time, from side to side, so I didn’t melt
the copper. Then I made a couple passes to have
enough martial for the mount. I couldn’t knock
the tubing out so I cut off one end and drilled the
copper out. A bunch easier than trying the remake
the holes drilling though steel and there still in their
correct location.
