Re: Cylinder Borning

In my mind, there is no point going out of your way to do the boring precise to plan. It really doesn't matter much since all can be corrected later. I have bored cylinders on the lathe both on the saddle and clamped on a four jaw. The finish is always rough and almost never to plan exactly. But lat...

Water gauge placement in a Briggs boiler

Other than placing the bottom fitting of the water gauge above the crown sheet, are there any considerations about how to plumb a water gauge into a Briggs type boiler? I've heard water gauges have accuracy problems due to boiling on the crown sheet.

Re: check valve

Do you need a check and shutoff for each pipe and both output into one, or can you just combine both inlets into one check and shutoff with one pipe out? Where would this valve sit - side of boiler or top delivery? What size inlet pipes? I'd guess 3/16" OD for 3/4 scale.

Debolt Machine Co and American ME Supply both have the little screw down grease cups. There may be others too

Re: Need source for graphited yarn for packing

I have a couple of boxes of the graphited string which may be asbestos since it is so old. It is the traditional stuff. Not worth as much for packing as the pure graphite tape which you can roll into a rope and wrap around a shaft. See McMaster 9481K11 for what we use at GGLS mostly. That said, if y...

Re: Ox Yoke™ Safety Chains

I don't think I would approve these for use at GGLS. We require the cars to be chained together, not the couplers.

Re: .032 copper tubing

It's OK to use for the pressures we have. But if you want to thread it, the 0.049" is a whole lot better. That's about all it boils down to.

Re: Silver solder flux

I bead blast it off usually, but where I worked they chipped off as much as they could, then put the workpiece in boiling water until the flux was gone. The flux does eventually dissolve in water.

Re: Hydrostatic Lubricator Drawings

When that article came out, I was interested in making a version for m 3-cyl Schools Class engine. I didn't have drawings but I looked at the article and figured out the function of all the parts and rough dimension, then made my own lubricator which had 3-pots rather than the Detroit's 4 pots. It i...

Re: Steam Dome Throttle

I agree that Artzberger's throttle works well. However, we had to put a ball valve to shut off the delivery pipe during boiler tests. Apparently the teflon block leaks badly when the boiler is completely filled with water as it would be during a boiler hydrotest.

Re: Restored Australian garrett in action

I am slowly building a double Prairie Garratt using Allen Models Consolidation wheels. The wheels set the scale at about 2.25, and the gauge is 7 1/2". I am using the Consolidation front truck plans for the front, rear, and inside trucks. The motor frames were water jet cut following the Consolidati...
