Re: Position of Safety Valves

Similar to yours, the prototype War Department S-160 Consolidations had the safety valve mounted at an angle on the boiler shell. The whistle was almost horizontal and piped from the side of the steam dome, which was under a casing, but the casing was lower than yours. They were done this way to pro...

Re: Plumbing for RRSC American

This is how Jack Bodenmann did it on a Disney CP-173. https://www.chaski.org/homemachinist/viewtopic.php?f=8&t=84771&hilit=disney&start=384 On my RRSC CP-173 I have an elbow from the center, front of the mud ring to an 1/8" ball valve and piece of tubing to direct the steam to the side. The ball val...

Re: Nickel Plate 762

Jack - what is the thickness of the copper you use as a wrapper over the end of the boiler? The next door neighbor was cleaning out his garage and gave me two 20" x 40" sheets of .020 copper. I'm guessing they would work to fancy up my boiler if I ever get that far along on the project.

Re: Locomotive Stand Test Rollers

Another project competed! I based my test rollers on the photo posted by Bruce Mowbray at https://www.chaski.org/homemachinist/viewtopic.php?f=8&t=106659&hilit=roller+stand. It would be nice to include his method to turn the drivers, but that would have involved additional work. Maybe later when I m...

Re: Steam railroading to return to Alaska!

The Alaska Railroad can turn wheel sets with outside bearings and they assembled and machined the wheel sets on our tender trucks. However, they no longer have a capability to mount the 33" wheels and axles with inside bearings as is used on our lead truck. We contracted with Alaska Roteq to turn th...

Re: Shimming driving boxes

My CP-173 frames were jig welded and Blanchard ground (per the catalog description). I noticed that the pedestal openings were slightly wider than called for in the drawing. So many years ago I sent a note to RRSC and Chet Peterson responded that I should use shims. The problem is that if the shims ...

Re: Model Steam Pressure Gauges

Cole's had a 1" diameter gauge and Godhall's now has a listing for them but they are shown as all sold out. My recollection is that the Cole's catalog's disclaimer about availability was that they were made by one person in his spare time.

Re: Model Steam Pressure Gauges

I have a photo of a 160 psi duplex air gauge built by Rich Dean. I think he stacked two commercial (2"?) U.S. Gauge gauges and modified one so that the shaft was hollow. Since it was sent privately I don't want to post it.

Re: Class Lamps and Smokebox Heat

Stainless steel is a lousy conductor of heat compared to other metals (16% of brass, 12% of aluminum, 35% of carbon steel). Using it for stand-offs or brackets would decrease heat transfer somewhat.

Re: Couple of Shorties

I think Berne did two articles for HRJ, one on the cars and one included info on making seats. My recollection is that the bottom and back cushions were made from standard wooden molding, glued together and then cut into seat length sections. I don't remember what he did for ends, but 3D printing wo...

Re: Brazing, heating and machining 3D printed items

Thanks. I have been curious, but this is the first time I've seen a description of what can be done with the 3D printed SS.
