Re: Dome Patterns

Even easier is to use lost foam casting. There are lots of instructions on how to do this on the internet.

Re: Water pressure gauge

I agree but be sure the highest value can stand the pulsating unless your cross head pump has an air chamber or something to even out the pulses. The best range for a gauge should be about 50% higher than the boiler running pressure just as the steam pressure gauge should be. Gauges work best at abo...

Re: Three Cylinder Examples?

My 3-cyl Schools Class locomotive has Walshaerts valve gear on all three cylinders. The center cylinder has an eccentric instead of a return crank which the outside cylinders have. It is a Henry Greenly and Earnest Steel design. There is a rather incomplete plans set for this engine in 7 1/4" gauge ...

Re: Alloy of brass and zink in a home foundry

Why would you want to add more Zinc to Brass? Brass is already an alloy of Copper and Zinc.

Re: Ejector problem

Adjust the orifice back or forward across the suction hole. If it works on air OK, it would require a positioning adjustment to get it to work on steam.

Re: Need a Foundry

Artworks, in Berkeley, CA has a good reputation. I've used them for number plates until I got my own capability. They have a website: https://www.artworksfoundry.com/ Did you try http://frostadatelier.com/ in Sacramento?

Re: O S Closing Locomotive Division

I remember Mr. Ogawa visiting GGLS back in the mid-1980s upon the occasion of the marriage of his daughter to a GGLS member. Sorry to see them close, but even then, the main source of income for the company was model airplane engines. His interest in locomotives was a sort of side hobby. In view of ...

Re: Glass tube for water glass

Yes, it will work fine. It is a bit thick. I'd go for a 1mm wall thickness. You only have a 3mm water column.

Re: Water Gauge Problem

New boilers frequently have foaming problems. I would say to wash out the boiler and try again. I would add some TSP to the boiler while filling and let it sit for a day or so, then flush it out with running water for a couple hours. Of course, it could be some other problem but try the simple thing...

Re: Model Steam Pressure Gauges

See Model Engineer 20 May 1988, page 602. Roy Amsbury describes how he made duplex vacuum gauges. And the one shown is something like 5/8" OD or 3/4" over the case. I'd like to have one about 1 1/4" OD for air pressure. I have the plans (sort of) for a 6" duplex vacuum gauge that could probably be c...

Re: Power Model Supply 11” pump drawings wanted

I have the 8 drawings for the 3" steam air/water pump. There is a sheet 5W that has the water end drawings. I have no idea what prototype this is for. The prints are too big to scan but I can take an iPhone photo for you if you like. If you are looking for the single cylinder pump then I can't imagi...
