Re: Steam Shovel

Here is a picture of an Atlantic Steam Shovel. It runs on Tracks. Patented in 1834, I think. I have a few drawings of it. Maybe enough to build one.

Re: 2d and 3d Design file exchange thread

[quote="hwboivin3"]So, after the previous comments, is anyone going to set up a place to host files? Caboose Light Zip file contains original .dwg file, an .igs and a .stl I down loaded this file just to see if I could print the STL on my printer. I found that the STL file won't function with Slice3...

Re: 3D Printing Sand Molds for Castings

Very interesting that sand can be processed into molds and cores. I can imagine core printing, but the mold is a little more difficult. I would think mold shipping would be rather iffy. I have a 3-D printer that makes things out of ABS plastic. Good for patterns and some finished objects that aren't...

Re: How do you ?

I normally use a hollow mill to do this sort of thing.

There is also the box tool and reading through the following reference will tell you how to make a simple one.

Re: A question for Marty on boiler chemicals.

Most of the boiler treatment concoctions contain a filming amine like diethanolamine. Morpholine is also used. The idea is to get the oxygen out of the boiler water and keep the pH up to about 10. This tends to keep the calcium and magnesium salts in solution which will prevent hot spots on the tube...

Re: Supply and return lines to clyinders

Jim, I'm building an NGG16 but it is freelance. I'm using Allen cylinders and Allen Consolidation wheels, Baker valve gear. I have the Garratt plans from South Africa to reference for a lot of the dimensions as well as Allen Consolidation plans. I also have waterjet cut frames.

Re: Supply and return lines to clyinders

Interesting topic. Allen models specifies (for the consolidation, at least) that the inlet to each cylinder is 1/8" NPT and the exhaust is 1/4" NPT. The area of 1/8 pipe is 0.06928 sq in. The area of 1/4" pipe is 0.10521 sq in. Thus, the ratio between inlet and exhaust is 1.52. a cylinder is 2" x 3 ...

Re: Attack of the Cyclops

Cyclops was a well known engine at GGLS in the 1980s. It was owned by Carsten Henningsen. Carsten usually took the engine up to the track with Jim Pate. Jim was the one who ran the engine mostly. You can ask Jim about the history of the engine. I think it is a Winton Brown design. Cyclops was not on...
