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...

Re: grey iron

I agree with Tristan. Both of our RGS20 locos at GGLS have grooves worn into the cast iron wheels. I have put tires on one of the locos so far and will have to do the other one next summer, no doubt. I used DOM tubing from Speedy Metals. With about 0.009" interference, the tires just drop on when he...

Re: Steam Dome Throttle

If you want a rotating throttle valve rod instead of a pull type rod, then use a right angle ball valve. 4847K12 from McMaster is the one I used. It operates like any other ball valve, of course, but one port goes up into the dome, the other forward through the front tube sheet. A little modificatio...

I've used flex hones for this type of polishing.
Flex hones come that small??
Flex hones start about 3/16" or 4mm. Cute little things.

Re: Cab roof material?

The references I see state that the roofing material was 'composition.' Supposed to be fireproof. I didn't find anything that said strips, sheets, or what. I did see a reference to Johns-Manville as a supplier and that implies asbestos composition. The Baldwin archives are in Texas somewhere and may...
