Re: Oahu RRwy apassenger car build qu

You might want to pick up a copy of 'The Work of the Railway Carman' by Edmond Hogan. It was put out by the Carman's Union. I believe it has been reprinted by Orange Empire Railway Museum.

Re: Mogul info

Little Engines offers two different Moguls, an old-time one with slide valves and Stephenson Valve Gear, and a Modern Mogul with piston valves and Walschaerts Valve Gear. Model Rails of Ann Arbor Michigan used to offer a Mogul based on the SP M-21.

Re: Walschaerts valve gear

Start by cutting the notch for mid-gear. Adjust the reach rod so the die block is in the middle of the link with the reverse lever (Johnson Bar) in mid-gear. Measure the full gear valve travel. Set the first notch where the valve travels the design amount. As an example, the Allen Mogul has a full g...

Re: Cabin Fever sale - 10% off Allen 0-4-0 and 2-4-0

I will have the 0-4-0 I'm building on display at my booth. I will also have a tender kit to show people.
The tender kit is for sale, along with a set of American drawings.

Re: Hydro Test

I use my ultrasonic thickness tester to check the firebox, especially the crown sheet.
When someone brings me a boiler to retube first thing I do is have it sandblasted, then I UT the firebox. I have found sheets that were 5/16" to start with that have thinned down to .110".

Re: Hydro Test

Nowadays, full-size locomotive boiler inspections include ultrasonic thickness testing at least every ten years. Back in the day, this wouldn’t have been possible. How much has this affected the way boiler inspections and hydrotresting is done? It is 10 years in Great Britain. Here, it is 1472 serv...

Re: Engine Tear down-Boiler removal-7 1/4 George the Vth

Amazing to see a riveted boiler that lasted 85 years...but I bet the legs are completely solid with rust and debris. I am curious are you sure the boiler is steel? (Which rusts) The reason I ask is I have seen other Bassett-Lowke George the Vth locomotives and they all had copper boilers. Keith It'...

Re: Hydro Test

A boiler inspector for an insurance company told me that they only hydro to working pressure. The thinking is to not stress the boiler, just look for leaks. any thoughts?? The hydrostatic test is NOT a leak test. The idea is to stress the boiler with warm water to find any weak spots. FRA rules for...
