Re: Personal watercraft stand for an engine stand

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

Re: Nylatron Bushing Use

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...

Re: Signal Scale

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...

Re: Need help in getting an Atlas Lathe operating

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...

Re: Oxy-acetylene welding steel boiler?

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.

Re: Oxy-acetylene welding steel boiler?

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 ...

Re: 1” scale air brakes

Considering just the locomotive, it depends on reliability of the compressor and if 20-30PSI is enough pressure to give the braking you want. If the compressor is temperamental or 20-30PSI isn't enough then no. The difficulty with most steam brakes is they lack a regulator making them essentially on...

Re: Silver soldering verses compression fittings

I have a locomotive 30+ years old with brass sleeve compression fittings on copper tube and no reliability issue. A key with any of the tube fitting systems is alignment and support. Don't leave it to the sleeve, flare or ferrule to pull the tube into alignment with the fitting and restrain movement...

Re: Axle box lube

We've run a 30w oil in a half bearing on a trailing truck. A felt pad runs against the bottom half of the axle. A couple squirts of oil each run has done nicely.
