I felt a mild surge of anticipation as I cut the firebox free of the fret and set to embossing the stay bolts and rivets from the back. Others are able to use half-etched rivet holes to make convincing, even rivets. Beautiful, even. So far, this is not a skill I can count on. Maybe […]

Driver bearings

I looked around at the various offerings for bearings in both the HO scale and 4mm markets and found they were universally too large for my purposes. Maybe a more modern engine would have such a large axle box, but my little teakettle needed daintier fittings. So, I decided to make my own. I believe […]

Bearings and the finest line

I made four driver bearings on the weekend, starting with a 1/8″ drilled hole in the end of some brass hex. Only after I’d completed all four did I examine them critically on an axle. They […]

Finished with casting drivers

After a couple of do-overs, I’ve finished casting the drivers for 622. It has not been a fast process, but at least it works, and I believe it results in a reasonably good wheel. I really should have remastered the mold before starting, as every wheel needed a little carving to account for overzealous application […]

Etchings arrive

The package from PPD arrived today and like a ten-year-old freeing a puppy on his birthday, I couldn’t wait to rip open the package! And then cut, and then rip some more, for PPD don’t mess around when it comes to getting their product to you safely. The two sheets were wrapped in tissue, then […]
