Re: Rapid Steam Pressure Loss

Hi, From what you say, it sounds as though you are getting way too much draft when running. "Stack talk" may sound nice, but even in a coal burner it wastes power. Opening up the blast nozzle until the ""stack talk" almost disappears is the way to go. I haven't run propane myself (just coal), but ev...

Re: Formed cab roof angle 16 ga. steel

Hi Dave, The method you use is going to depend entirely on how sharp you want the outside corner of the angle to be. If a 1/16" radius is acceptable, then cutting the angle from square tube will work, if you want to wind up with a sharp corner like real angle, then you will have to mill the angle fr...

Re: Steam turbine generator

Hi, This is an old thread on turbogenerators, but recently I talked to Bill Huxhold about the ones he made and I have some important advice to pass on to anyone who may have one of his units. Bill designed his turbogenerators to run at about 40,000 rpm. using 40 psi. steam pressure. That is why each...

Re: Two Silver Soldering Questions

Hi, I started off using the white flux a long time ago, but I found that if I overheated it, it burned and then it didn't work any more. I found that the black flux wouldn't burn and was better for large jobs like silver soldering a flat car frame together. For the truck frame you will probably need...

Re: Union copper tube to 1/4-40 MTP ?

Hi Dianne, My cross slide was the same as yours so a long time ago I took the carriage off, made my own dovetail cutter from a broken tractor drawbar & put the carriage on the mill. I took just enough off the ends so it was straight across. When I reassembled it, I used Tempur tape (1/2" wide teflon...

Re: Union copper tube to 1/4-40 MTP ?

Hi Dianne, David's "how to" page is very good. That's the same technique I use, but instead of a cone on the ferrule, I file a ball shape. Both techniques work, but the ball has a smaller contact area in the female cone and thus should seal better. I also have a supply of Viton "O" rings and stainle...

Re: Union copper tube to 1/4-40 MTP ?

Hi Dianne, I make all my fittings and once you get the hang of it, its pretty easy. I use collets to hold the fitting in the lathe which helps a lot in keeping everything true and lined up properly. By making my own fittings, I can go down one wrench size over the commercial fittings and still have ...

Re: Hello, I am new here and am trying to build an Atlantic without a metal lathe.

Hi, If you are serious about using a 3D printer as your only tool to build a steam locomotive, you are doomed to disappointment. Using such a printer would be appropriate for some of the appearance parts, but even there its use would be limited because most builders want things like headlights, pump...

Re: Ever seen an injector cut in half?

Hi, Fred beat me to it. The left side is the pressure recovery cone and goes to the boiler feed valve. The right side is the steam cone and comes from the boiler. The bottom connection is for the water supply. The middle cone (in two parts) is called the combining cone. In the top center is a ball c...

Re: Ever seen an injector cut in half?

Hi Anthony, I'm impressed on a number of levels. First, your picture is perfectly sharp and clear so it is easy to see all the detail in both the drawing and the injector cross section. The drawing helps in understanding the injector cross section detail. A beautiful job! By comparison to yours, the...

Re: Tips for a newbie

Hi, But you can do that with 3 1/2" gauge! A Big Boy no, but a 4-4-0 or even larger is quite doable. Anything you can pick up by yourself is a good candidate for trunk transportation. Even a small 7 1/4 / 7 1/2" is going to weigh several hundred pounds, a big one can be several thousand pounds. Tom ...

Re: Union Pacific Big Boy in 3/4 Inch Scale

Hi, After I posted the last four pictures, I noticed there was a horizontal yellowish band along the side of the boiler. There really is nothing there, its just a reflection on the paint of the yellow lift table the engine and stand sit on. Its a long, slow road and there is still a lot left to do, ...
