The Running Boards 2

The boards are finished on the left side of the engine. You can see how paintig the sub-plates white before installation has made it so easy to get this look.

Thanks Thomas.

Now for the running boards on the right side of the engine.

When I picked up this heavy part, I thought it was simply a tool box. But upon checking the parts list, I found it was an oil pump box.

Silly me.

It's solid zinc!

There is a picture of it in the instruction booklet with the doors open. Quite a few operating parts in there with a crank handle.

It bolts up under the front right running board.

You can see the oil pump box in place in this photo along with a check valve fastened to the side of the boiler above the running board. It has a pipe that runs forward into a pipe cover.

The picture of the pump box doesn't appear as if the doors open though you referred to a picture in the instruction book where they were. Can you clarify that?

You are right Bill, the pump box is a solid casting of zinc. I learned about its contents by observing these pictures in the booklet.
Looks like a something being operated by a rotary crank. You can see the doors open.

Oh I see now...I was thinking the pictures were of the model and not the prototype. Thanks for the clarification John.

Yes - the longer arm in the picture would connect back to the valve rod or something like that, to push the long arm back and forth - inside would be a ratchet on the rotating part of the pump crank. The little handle let them turn it manually to put in extra oil for startup. Excellent details!

Thanks fellows. As we go along here, please jump in at any time when you see a part with a specific function of interest. I think we all would like to learn as much as we can about the many functions of an otherwise very confusing collection of engineered parts.

The first photo shows the threaded location for the compressor support bracket.
Photo two shows the compressor support bracket
Photo three shows the compressor with a regulator attached to an exiting pipe.
Photo four shows from right to left: discharge reservoir, filter(?) regulator above and compressor.
Photo five shows air reservoir and cooling tube (?) that will come out of the compressor.

Man this is fun!

John

Hello JL,

All the parts that you have shown so far are absolutely beautiful, I am guessing that they all fit perfect. Enjoying this build.

Have a great day,
Thomas

The detail is incredible John!  Excellent building technique as always.

The Left Air Reservoir and Cooling Tube
« Reply #118 on: May 11, 2019, 05:21:25 PM »
Thanks fellows.

Don't really understand what is going on here, but the parts went into place very nicely. The pipes were bent perfectly to slide into thier respective holes.

The end bracket (photo 3) is made of two pieces - one behind the pipes and one in front.  Both are bolted together down through the floorboard.

The compressed air coming out of the pump will be hot, the extra loops would let it cool. Not sure why they would need it to though...
