Re: Steam Dome Ball Valve Throttle

I have been heard to say 'If they had ball valves in the 1920's you'd have seen them everywhere on steam locomotives!'

Re: Prototype Poppet Valve Throttle

I have rebuilt and serviced full sized balanced poppet throttle valves for logging steam locomotives. They were very picky and difficult to make properly seal. I shudder to think what one in miniature would be like to make operate properly. My thoughts. RussN What Russ said! Russ, don't denigrate y...

Re: Steam Dome Ball Valve Throttle

When we assemble the throttle we put some blue Loctite on the nut so it won't come off accidentally.

Re: Boiler tube length question

Peter may be referring to girders as longitudinal stays. I much prefer to use rod stays rather than girders. It is much easier to calculate the area rod stays support.

Re: Boiler tube length question

We own, and frequently steam a 4 inch scale Fowler traction engine, In 20 yrs the copper tubes have moved slightly forward, they now, in the firebox tubeplate, can be seen to leave about 3/16 inch of tubeplate exposed, Strangely we have not seen nor experienced any leakage. Hope this is of interest...

Re: Boiler tube length question

I've been around at least a dozen 7.5 gauge coal fired engines with copper flues and zero issues. This is how Marty has built probably like 200 boilers and no issues that I've ever heard of. Just roll in the copper and be done. I have now built 390 boilers - 7 all copper, 10 steel with steel tubes,...

Re: Soldering - GAH!

In both soft-soldering and silver soldering you need to get the metal hot enough so the metal melts the solder, not the torch. I clean with Scotch-Brite, I even Scotch-Brite the solder before I apply it.

Re: Wabash, frisco and Pacific/ Mueum of Transportation

Noah and I had a great time at the Museum of Transportation and the WF&P! At the MoT he loved the KidSteam hand crank cars and seeing the Big Boy! We rode the Chance train and the trolley, and I got to see the Wabash 573, the prototype of the Allen/Harpur Mogul. Mike Walsh told the WF&P we w...

Re: Alcalde & Coalfield High Line

Take all the fun out of it! P7094962.jpg I think this has been rebuilt to be closer to your (much better) design Jack, but it was exciting while it lasted. If the engineer pops in he can describe the experience. Geez, John, what a flattering photo! The engineer has dropped 60 lbs since this photo w...
