Crank pin idea

Beautiful summer weather rarely inspires much railway modelling. It’s a better time to sit on the deck and enjoy the outside of the house than the inside of the basement. Today the idea book came with me so I could capture that elegant crankpin solution I suggested a month or so ago. I believe that […]

Plan for quartering jig

While I have the excellent GW Models wheel press and used it on #10, it has two failings from my point of view. First, it assumes a press fit for the wheels; that’s one thing with a plastic centre, but another for steel centres and axles where the two parts need to be machined to […]

Bad crank pin holes

When you simultaneously wreck a part and break your last drill bit of that size, it’s a good time to take a little rest. Actually, I’ve now pretty much committed to mulligans on two out of four drivers, which will teach me not to celebrate finishing some parts until I’ve finished working with them. Despite […]

Crank pin holes

To line up the crank pin holes and get them the right distance from the axle, I have created a little jig out of 1/16 x 1/2 inch brass. Using relatively heavy material like this should keep wear to a minimum, at least long enough for two or three engines. The jig is pointed at […]

Crank pin proof of concept

The M0.6 screws and nuts arrived just before the Railway Modellers’ Meet, and now that most of the dust has settled, I’ve spent a part of a glorious spring morning trying out my idea for a crank pin. When the weather’s as nice as this, progress on the locomotive has to slow down. Vancouver winters […]

622 ready for the show

Well, I didn’t quite make the audacious goal, and now I am almost out of time. The Railway Modellers’ Meet starts on Friday, and there isn’t a nanosecond of free time between now and then. So, I am unlikely to make much more progress. What we see is what we get. Having said that, it’s […]

622’s boiler roughed in

The plan for 622’s boiler is somewhat experimental. Because the engine is a split frame design, and the running boards are connected to the frame, the boiler needs to admit both polarities too. At the same time, these little engines are mostly air, and so, we need to fill the boiler with as much weight […]

622’s Cab Takes Form

I tell you what: this business of starting with etched parts is really a lot faster than forming parts yourself. I spent about an hour this morning laying out and forming the four key-holes that I use to screw the cab to the frame, and which somehow I forgot to include in the pattern. If […]

Engine truck good enough for now

Rebuilding the engine truck wheels, including one tyre that went missing (but is not missed as it wasn’t my best work) took a morning. This time I soldered the half-axles in place before casting the spokes. So all the wheels are nice and solid now, even the one that came apart in the heat and […]
