The air pump was, like the rest of the loco as I am finding, is different from the stuff that was available to me on the American parts loco. The air pump from the Bachmann Big Hauler is the closest for size, but to make it a decent model would take as much work as building from scratch. I had two choices, 3d design and print it, or make it. I chose to make since I could make it mostly for free from stuff I had laying around.
The first thing was to understand what I was trying to build. Of course I have David Fletcher’s drawing of it on the loco, but I needed to understand to how it worked so I could make sure I was putting things in place for a reason. Again David Fletcher’s Masterclasses to the rescue. The problem though is that his classes and almost all online resources refer to the second generation and up air pumps. There is very darned little on the internet about these pumps.
I started by building a pump based on Davids instructions, but modified to the sizes of the 6″ pump. It is taller and skinnier than the later pumps.
I spent an hour looking for through my photos to fine one of the assembled air pump shown in the photo above. Then since I couldn’t find a photo I went looking for the actual piece to take a photo of it. I was rather disappointed with how it came out, so I must have tossed it. The pumped looked kind of sad because no matter how hard I tried to ensure that the center C shaped piece was square, it was not. The top leaned over looking kinda Bill from the School House Rock “I’m just a Bill”. Not that much, but enough that you could see it.
The second issue that led to it being tossed was that I did eventually find a drawing of the original 6″ pump and combined with photos of the real thing I found that it was not constructed the same as the later models.
Wow, time flys. I didn’t realize I had a half finished post sitting waiting to be posted until I finally had time to come here and look after my site. I last looked at this site back in May. Late spring hit and that was it. I was waiting for drivers to come in. That took forever. We were going camping, so I needed to get my vintage camper ready. Finally here I am four months later and I can devote some time to this.
