Replacing a Quadrant

Throwing the engine lead switch, there was an unusual “thunk” and then the lever moved a little too easily. Reaching underneath, I felt a new sharp edge rotating behind the fascia. A couple of the levers have needed replacement, but this was the first quadrant that broke. Fortunately I still have the drawing. The new […]

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. […]

Turnout controls installed just in time

With the Railway Modellers’ Meet descending on Pembroke next weekend, I have installed the turnout controls just in time. I still need to paint the rods on which the handles pivot, but that is cosmetic and might wait until after the guests have left. The controls almost meet my vision, but they need some gap […]

Ten handles

The handles for the turnout controls need to be strong enough to handle. So, rather than printing them, I fabricated them from brass. This was one of the many times I’m happy to have a small layout. Ten was just enough: any more would have been tedious.

Installing Turnout Controls

Awaiting a custom set of N-scale Grand Trunk decals from Black Cat, I have had to put Percy aside for a week or so. Meanwhile, I’ve been honing the approach to installing turnout controls. These controls had to satisfy the following design criteria. They need to behave like a real switch stand. I want to […]

Turnout controls ready to print

Eight years! I am amazed to learn that I started pecking away at the fascia-mounted turnout control problem eight years ago. Well, this week marks the conclusion of the design phase, as I finally have a version I believe will be robust and easy to install. This is a minor improvement over the Mark II […]

Turnout control Mark II

Now that I almost have a functioning locomotive again, I’m eager to get back to operations. As I had to get the 3D printer out to create a new steam dome after the first got chipped after its tungsten weight propelled it at the floor, I decided to try out a plan for an improved […]

Turnout controls started

Well, I really thought tonight was the end of Daylight Savings Time, and per tradition, I made use of the extra hour to work on the layout. It is an especially welcome hour this year as we are only 7 days away from the layout tour. Mark Dance suggested I attempt to get the roundhouse a little […]

Sorted: Engine House Switch

As I mentioned a couple of weeks ago, there are a number of things that need to be resolved before I’ll be anywhere near satisfied with operations on Pembroke. I find it rewarding to share progress, and every little bit of motivation helps when you’ve got a job you’d rather not do. So, I’ll apologize […]
