The Home Machinist!

There is a book with the Clishay build articles. Very few castings. With either you have some instructions to go with. Kozo's information from what I see is more detailed. I think the A3 has to be scaled up to 7-1/2" gage. Off the cuff they are equally accessible. There are other small locomoti...

1)What skills are most important in building a live steamer, Machining is at the core of building a locomotive. How to measure accurately. How to read a drawing. How a locomotive works. Welding for example is something many people seek help with. and what projects should I embark on to gain those s...

Mine are between the dome and the rear tube sheet.

A V-Flat drive. Never knew such a thing existed.

Here is a short video that should make it easier to visualize.

There cannot be many people around who remember Harold Ekstam. I used to see Harold and another guy at Harry Herder's double heading the moguls. I remember them both being tall and hunched over the moguls. I asked the only person I know who might know where the Scotty mogul went. I have not heard ba...

Looks like a monotube steam generator. Steam powered car on a larger scale. Some of the claims seem a bit dubious.

If I remember the 60,000's water tube firebox purpose was an increase in efficiency and an increase in boiler pressure above what stayed sheets allowed. By reports it was successful in efficiency improvement compared to locomotives it was tested against but suffered from water tube failures. I used ...

rotating around the horizontal axis that is perpendicular to the rails An Andrews tender truck would be much like a freight car truck. In 1-1/2" scale there is a general consensus that any one wheel can be lifted 1/4" from the rail without lifting any of the other wheels. The pitching is ...

I can't speak for Canada but from my view on the Midwest U.S. is it dying? No. Has it changed? Yes. Generalizations are risky but here goes. People are raised differently than they used to be. I grew up in the days when kids got sent out the door to go find their friends. We met up at the school and...

The post said 1/6 and the signature bar says 1.6" scale. They are quite different but it conveys the idea.

Call your 1.6" Challenger 1/8 scale to make the math easy. As Russ said mass increases by the cube of the size increase. In 1/8 scale your model would decrease by the cube of the decrease. The model would be 1/8 the length, 1/8 the width, 1/8 the height. 10,000 ton/512 = 19.5 ton or 39,0063lbs....
