Refined Switch Lock Design

I’ve never had a ton of luck with Assembly views in OnShape. Until now. As I was idly rotating the design, as I so often do after building a 3D model, I started to wonder if the key will actually turn past the end of the lever, or if it will jam. And anyway, how […]

Switch Lock Designs

I had a couple of friends over to run trains over the last couple of weeks, and it made me realize that the whole operation needs to slow down even more. The chains that will retain the keepers and locks on the turnout controls have been dangling long enough. It’s time to get the locks. […]

GTR 1120 Wheel removal and replacement

I’ve looked in vain for a video or description of someone else who has successfully taken apart a Spectrum 4-4-0. A lot of the parts seem to be glued or held in place with invisible tabs. The exploded view diagram was no help. So, rather than risk further damage to the model, which came with […]

Wheel-fitting Heresy

The standard approach to putting wheels on axles seems to be – well – to put the wheels on the axles. The assumption is that the wheels are complete: they have their tyres and crank pins. It’s easy to see why that would be the standard. If you buy your wheels, they naturally have tyres […]

Studying the Copse

While waiting for The Girl to finish her roller skating class on Sunday, I had some time to sit in the car and study the copse to the left (north) of the pasture in more detail. Returning to Flickr, I had to find my reference material once again, and along the way, I amassed a […]

Pasture gets more shapely

Armed with a utility knife and a Stanley Surform, I hacked great swaths of Styrofoam away from the hills. It’s curious that so many modellers like this material. It’s messy and the dust sticks to everything. While easy enough to form it into hemispherical lumps, dips and bowls are difficult to form. Then, what if […]

Rough and Scrappy Scenery

There has been a pile of Styrofoam where the pasture belongs almost since the layout was installed. Indeed, I think that stand-in landform was a heap of scraps left over from the basement renovation. With the success of the mock-up, however, I was ready to commit to the scene. To support the test backdrop, I […]

Playing with Wire

With the coming scenic modelling, I decided to pick up some florist wire and see what it was like to try to create a tree-like shape a la Gordon Gravett. Michaels didn’t have the paper-coated stuff that Gordon uses, but they did have big spools of this plastic stuff, and it wasn’t very expensive. So […]

Crank pin parts

The crank pins for 1120 are much heavier than those of 622, and as a result much easier to fabricate. Most of the time in their fabrication went to tapping them for 0-80 bolts as my tap kept binding when I tried to reverse it out of the holes. Even so, the pieces are tiny, […]

Bearings

There is a point after you’ve accumulated some hours with a tool or technique when it becomes enjoyable. I think, after five years with the lathe I am finally there. Sure, there will always be parts that will challenge me, but simple ones, like these bearings enable me to get into a rhythm of turning, […]
