The Home Machinist!

Well that was the years ago part. Harry Herder had Caviler coal. There will little aluminum tags in it that said "Consol Caviler". It burnt well but smoke, stink and burn your eyes. There is about 50lbs left I'll burn on some special occasion. Along with the availability of coal I have won...

Coal varies depending on where in the region it's mined. Years ago I had a tour of the Ravensglass and Eskdale Railway. A truck delivered a load of coal from Poland. I asked why they weren't using Welsh coal. They said the coal coming from the Welsh mines had too much slate in it. They expected it t...

For the live steam hobby, a shift from coal would be more symbolic than anything else. The amount of CO2 a model steam locomotive produces pales in comparison to amount generated in daily life and the low hanging fruit available to society. But if you are a tourist operator or preservation society d...

what is the easiest and simplest step by step procedure to do the boiler wash and what kind of soaps, detergents or chemicals can we use that are safe for boiler washing. as well as what kind of equipment to use to get inside the boiler. CLR is a common chemical used in washing boilers. I use white...

Perhaps it is the limitations thin wall plated tube would impose on modifications.

The record for distance covered by a miniature train in a 24 hour period is 204.9 miles. This is with a coal fired 4-4-0 using Vesconite bushings on the rods. https://www.machinedesign.com/mechanical-motion-systems/article/21838239/polymer-bushings-help-steam-locomotive-set-world-record-for-distance...

Based on the two railroads I run on with signals, 1.5" scale is probably the lower limit of what is easy pick out at a distance. The type of light, lens and how it's aimed have a big effect. There are a few signals that even though I know they are there that are difficult to pick out of the fol...

These are the pulley diameters on my Atlas 6".

That looks like an older 6" lathe. I have one similar to the lathe in this video. https://youtu.be/-3WUTFSSPWk?si=WYqPbQsr8wjecyjM Near the end you get a decent view of the drive set up. I can measure my pulleys when I get back home next week. From the factory the 6" lathe came with a 1/3H...

Looking for where oxyfuel welding is still used I came across an EAA course on oxyfuel welding for aircraft work. I got a chuckle out of their description. They teach welding for aircraft, no tractors no cars. They will only talk about aircraft.

While vaguely similar to TIG welding a major difference is the electric welding processes can apply more energy in the weld zone giving better penetration. We did the gas welded box exercise in school. The material is considerably thinner. Move up to boiler thickness materials and it would get much ...
