Interesting, I did some searching and I guess you're right. Anyway, all the parts are clean now. Any paint still stuck from being burned on will be painted over.

The mounting feet for the dummy water tank have always bothered me so I'm re-doing them.

Marking the solder locations for the feet and soldering them in place. Getting them soldered in just the right place was just as touchy as I remember from the first time (this is why the holes had to be drilled so weirdly). Thankfully I'm more practiced now.

Marking and drilling the mounting holes. I think I did a better job this time. This process is consistent with the tooling available to me when I first built this. I didn't have a lathe or a mill but I did have a belt sander, drill press, dial height gauge and a small surface plate. The last picture is the first selection of parts I need for the re-assembly being primed for paint.

Top coat added to the first set of parts. Later I decided the cranks and side rods were necessary to the first set also.

For this part allow me to gloss over the fact that the real 1:1 locomotives did not have link and pin couplers.


The couplers have too many pockets and the mounting holes were left unfilled by fasteners. Before and after.

Ok, ok... I know what you're thinking: Hey this is just a re-paint! While I won't disagree, let's take a look at the single cylinder oscillating engine to get an idea of the state of things.

The greatest area of wear in in the crank pin, more on this later. While all motion joints of the locomotive have wear, it's not as much as you might think with the least amount exhibited at the fit between the axles with the axle bushings.



Overall, the oscillating steam engine has it the worst. After the crank pin, the fit between the drive shaft and the frame of the steam engine is second worst. The fit between the piston and cylinder is surprisingly good though.


That said, these wear locations aren't really fixable. If there were more material cast into the frame of the steam engine, I could drill out the drive shaft hole and press in a new bushing with something similar being done to the crank pin.



No, the only way to amend the wear would be to build anew, but why bother? For now it still runs. I'll build a new single cylinder oscillator once this one is completely finished.

I have been using Lacquer Thinner for cleaning. It contains Acetone but is easier on the hands and does not evaporate as quickly.
There are different grades of thinner Finishing and Wash. The Wash is a bit harsher and cheaper and better for cleaning. The finishing thinner allows the lacquer paint to dry slower thus giving it a better sheen.

Both nipples on the steam engine frame were loose. A little Loctite 603 firmly setsthem back in place.
