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.

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?

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 ...

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.

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...

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...

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 ...

]Something like this?:

Might be manganese bronze which is about 20% manganese and 20% zinc, 56% copper and a little of this and that. If so, I'd guess the pouring temperature to be about 1600 F. So you could try reducing the temperature if you are melting at a higher temp. Machinability about 80. Not too good.

Looks to me like the one that appeared in Live Steam mag years ago. I made one that looks just like yours from the plans in LS. Value...whatever you can get for it.

Steve Vitkovits designed and had castings made for a light 2-8-2. Dick Thomas was also involved. The design was sold to Railroad Warehouse. Dick Thomas had a full size erection drawing of the Baldwin 2-8-2 90 ton Mikado. Steve saw the drawing and said to Dick: "Lets build a locomotive." S...
