Now it was time to start work on
the frame. The first thing made was the frame ends. Started with some
1/4" angle iron and rough machined it..
After bending the corners and
cutting the angle iron to length, this is what things looked like so
I couldn't resist putting
everything on the trucks to see how it looks.
Before welding the frame
together, I wanted to do as much machining as possible with loose pieces
so it would be easier to put in the vice. Drilled tons of holes on both
sides of the angle iron. This will be used as a template for the sheet
metal sides. Drive screws will be used in this section.
Here's everything so far. Still
have to do more machining and cutting on the end pieces before welding.
The 1/8" plate was measured and
cut for the frame decking. Things are already starting to get pretty
heavy. Once I get all the pieces cut, machined and fitted, then I will
weld everything together. Next is to start on the body framing.
truck bolsters were made and attach.
The end plates are finished and
sand blasted. Here's a picture of all the clamps holding the frame
together just before being spot welded in place.
After spot welding the
underframe, I temporarily put it on the trucks to see how things looked
Next is the framing for the
I wanted the scale of the tender
to be accurate. The problem was that the 40lb propane tank takes up a
good portion of the tender. Not only that, but the propane tank only
had about 1" clearance from the top and sides of the tender.
To take the tank out, the front
has to be tilted upward and wiggled out. It still rubbed up
against the tender in places so grinding took place to get a good fit.
This allowed me to keep the prototype dimensions without having to
resort to smaller propane tanks or come up with
something else. A "guillotine" door at the front of the tender was
made in order to get the tank in/out as the fit it very tight. The picture below shows a
portion of the body framing done with the propane tank.
It's starting to take shape!
Two stainless steel baffles were
made for the water tank to keep the water from sloshing around. They're made
to be removable to make access
to the pumps, piping, filters, easier. It will also make it a
lot easier to waterproof the inside of the water tank. Brass tabs
hold them in place. Stainless and brass were used to avoid
