Caught the short

Because the top layer of the front cross-member admitted a gap, I broke the isolating cut into two sessions. Yesterday evening, I cut through the front half, in the hopes that the short was there. It wasn’t so, after the epoxy holding a new frame sandwich together had cured, I severed the back half. I […]

Chasing a short

It wouldn’t be one of my builds without some sort of disaster at the end. On #10, I dropped the boiler on the way to the paint booth, breaking the smokebox off completely. For 622 the disaster is a short that has developed in the frame since the last time I tested the locomotive. At […]

Anchor Tenants

There seems to be a social-media contest for messiest workbench. Many modellers get chest-puffing macho affirmation by claiming that they can still produce amazing work even when the bottles of paint and boxes of partially finished kits are threatening to obliterate the remaining 6 square inches of usable work surface in a cataclysmic avalanche. I […]

Tender side sill details

As I mentioned, the tender side sills were looking a little barren. So, I scurried over to the reference material to see what should be there. Interestingly, this is a point where 622 differs from its stable-mates. The details were straightforward to put together with strips of brass and some Grandt Line nut-bolt-washer castings. Now […]

Tender details

I thought this post was going to be called “Tender final details” until I looked at the photos. Don’t the side sills look plain? That’s what I thought too, and it sent me scurrying to the reference material. So, there’ll be another post tomorrow. It turns out the handrails and lift bars are only the […]

Mars Accuracy

I’ve noticed that the prints on my own 3D printer are snug compared to the same parts printed by Shapeways. Indeed, the sand dome and the ash pan wanted a little scraping where they connect with other parts. So, I made a 2 cm test cube to see what I could learn about the accuracy. […]

Sand dome for 622

It turns out that one of the benefits of having your own 3D printer is that you can afford to experiment a little bit. If a part doesn’t work out the way you thought it would, you can modify the drawing, export it, and try again. There is no 10-day wait, no shipping charges and […]

Mars sees its first action

For Father’s Day this year, my darling wife bought me an Elegoo Mars 3D printer. Well, summer being what it is, it has taken me a while to get it out of the box, but now that it is in action, I must say I am truly impressed. Now, I will confess that I have […]

Boiler stays for 622

The front boiler stays on a steam locomotive are tricky. They need to connect the boiler to the frame, but at least one end can’t be permanent or else you’ll never be able to disassemble the engine. What’s more, they are right there on the front of the engine, front and centre for most photographs; […]
