Extra-long jig axles

At least I think they should be called jig axles. These pieces of Aluminum rod are used with the coupling rods to ensure the bearings are exactly the right distance apart. Essentially, I will pass these rods through the bearings, fix the coupling rods to the outsides, and then solder the bearing guides to the […]

Crankpins for 622

This weekend I formed the crankpins. They are turned from brass as I found, when turning the prototype, I couldn’t drill a long 0.6 mm hole in steel. I made them slightly over-length so I can trim them after I see how thick the rods really are. The real trick was the washers. These are […]

A summer well-spent

It has been quite a summer. Between three weeks in England and France subjecting the kids to an intense dose of European history and culture, a long weekend in New Brunswick attending family functions, and a week recovering at a cabin on the Sunshine Coast, there hasn’t been much time for railway pursuits. What little […]

Surprising failure in wheel experiment

Something has been bothering me. I spent a lot of effort to get the hole in the drivers concentric with the tyre, but then who knows what happens when the axle passes through that hole? Indeed, I’m fairly certain the axles are neither concentric nor perpendicular to the tyre. So, as I have to make […]

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 […]
