FT-A & FT-B Stewart Engines

construction sign

Older projects I started and want to see finished

This project started in late 2006/early 2007. There was an article written up in Railroad Model Craftsman in November, 2006. I purchased four locomotives, two FT-A and two FT-B. The B units would be turned into FTSB units. The S stood for "short". Stewart FT engines were used for this project. I started the first B unit shortly after the article but never finished the second unit. I'm trying to finish these up during the winter of 2011/2012. I'm also going to add DCC. A first for me.

The two A units and the two B units with the body removed. The one on the left has been modified. The one the right has not.

Closer view of B uits. Left modified, right not modified.

Cut off the step with a single edge razor blade.

Next I took a razor saw and just cut deep enough so I could use the saw cut as a mark to scribe a cut line on the side panel

Eyeing up the previous mark use a straight edge to scribe a line about 1/32" from the previous cut mark.

Cut through the side 1/32" from the scribed line.

Cut all the way to the roof line.

Then cut straight down until you run out of saw. This will leave a saw cut line to line up your saw for the cut across the roof.

Here you can see the saw cut lines that will be used to line up the saw for the cut across the roof.

Making the cut.

There you have it. The rear portion cut off. Now it needs to be trimmed flat.

Next a section needs to be cut out to make the shell 41' 9" in HO scale or 5.760" inches long in human scale.

I had made a couple of light scratches on the shell with the verniers to line up the scale with and scribed a cut line. Do this on both sides of the shell.

Then I cut through the shell approximately 1/32" from the scribed line. Again do this to both sides.

Again cut all the way until you run out of saw and used the lines created in the roof to line up the cut across the roof.

Then cut through the roof using those previous made cut lines to line up the saw.

The finished cut. Discard the scrap piece.

Now for a bit of trim work and some liquid glue.

Here's were some of you will have to use a bit of elbow grease and a file, plus some sand paper. I used my Sherline lathe/mill combo to do the work. Here the mill is set up to mill off the portion left after the cut to make the back flat.

Back all nice and flat. Some clean up with a file and it's done.

Side is lined up square and the cut is made to the previous scribe line.

Same procedure for the roof.

All cleaned up and glued to the shell. Next step is to do the frame.

Remove all the plastic parts. Even if you don't have a mill to do the job. Makes it much easier to trim off the end if you have to hold it in a vise to use the hack saw and file.

Trim off the end so the shorter body will fit on snugly.

All cut off and trimmed up with a file. I did cut a large portion off with a hack saw before milling. The mill complained a bit cutting that much waste of the end.

The shell mounted back on the chassis. Next, open up the roof to fit the panel.
