Quartering jig

I mostly completed the quartering jig before our vacation. It consists of two steel bars separated by aluminum spacers and with axle holders also made of aluminum. I’ve not yet drilled the crankpin holes, but a test fit of some axle material showed it was remarkably and satisfyingly accurate for a bodger like me.

Pilgrimage to Pendon

It’s easily more than a decade since I was last in England, and so, on this summer’s holiday, I left the eye-rolling family at home for a trip out to see the Pendon museum. We were staying in Henley on Thames, and the museum was a morning’s excursion when the rest of the family wanted […]

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 […]

Frinspiration

We are just returning from a trip to England and France. As I was the chief planner and driver, it is perhaps surprising that there weren’t more railway visits along the road. Sadly, every such suggestion is met with universal eye rolling resistance. I did, however manage to “stumble upon” le Chemin de fer de […]

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 […]
