Very true; there is a reason for the low-temp alloys like Cerrobend, etc.They
can be poured into the cavity without adversely affecting the solder joints.
Granted they are more expensive than lead, but what price do you put on your
vision and exposed skin?

Keep the cold water in a room separate from the hot lead. Will NOT mix well

Bill,
You might recall that several of us here in the Houston Club went to
a chain drive to replace that ribbed belt. It resulted in a much
improved drive, but like lots of drilled plastic on metal shafts--if
you make it tight it might split or if you make it snug, it's likely
to slip. So the choice was slip or split! I ran mine for several
years that way.
So for round three, I chose to go to the SHS F unit trucks and some
Overland motors (via ebay). They are in a state of--"when I get to
it" right now. However mine have very nicely done paint jobs (photo
on the S Sig site) and all the required lights. I replaced my
handrails early on as well as adding winterization hatches,
different horns and a few other long forgotten items. I think your
drive method might have been simpler as I have to cut into the brass
floor and fasten some custom made bolsters when the time comes.
However, I have chosen that method and I lack the extra drives from
Overland. Maybe we can get together and have a NMRA/NASG authorized
pulling contest!
I'll mention two things about the original models--first off I think
they were the only Japanese produced brass models in S since the
J&L tank car and they pulled very well.

It might
not look much different than the other day but it
really is. I scrounged some usable driveshafts. The
original “bolsters” are just bent sheet metal. It is
too thin as well so the sideframes were free to
wander. I soldered a piece of channel across the width
to stiffen it up. The axles don’t just pop put of the
sideframes now. I changed the body bushing from nylon
to a brass bushing soldered on to the floor. At the
same time I converted it to 3MM O Scale truck screws
and a chunky spring.
This
drive conversion from the rubber band wonder to
conventional was stupid simple. I wished I “saw” it
earlier. Just clipped to transformer power it is
pretty quiet too. With the stiffer bolster the wheels
can get close to the sideframes so there is probably a
massive short. I have to address that somehow. All
wheels are set to insulated on the same side. I have
to make some wipers for the insulated wheels.
The
handrails are taking a real beating here. They are
likely to get removed shortly to get redone with new
castings and phosphor bronze wire. So much for a
simple completion! I wished the floor was separate
from the drive like on Overland diesels.
If anyone
should happen to have a spare fuel tank from the
Sunset GP7 or GP9 I am interested. This unit has a
rather shortened tank. I would not mind having a
spare. After shortening it I want to float it in cold
water and fill it with lead to make a chunky weight.
Never tried it. It could be a hoot.
A few
more hours fiddling then it is going back in the box
for another day. Gotta start on other things….
Thank
You,
