Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I picked up a another Bing at a pretty good price.  I didn't need to do much to this little engine and going to pretty much leave it as is.

1927~1931 Model steam engines with steel-blue patinated brass boiler (made of drawn tubes) and fixed forward- and reverse-operating steam cylinders, Nickel-plated fittings, mounted on a solid, painted iron base. Height 33cm / 13 Inches

I changed out my gasket & doubled up Weeden seals for some O-Rings I got off Amazon today.  They are 3mmx10mmx3.5mm Nitrile Rubber O-Rings.  I also bought 4mmx10mmx3.5mm but 4mm ID was too big and leaked as soon as I put water into the tank.  I also meant to get Fluorine, since it has a higher heat tolerance but the Nitrile appear to be doing well after two steam tests.

I have a spare Bing sight glass that came off a 10/120, its glass OD measures out to be 4mm and this candlestick measures out at 3.5mm.  I do like the fit on my spare a lot better but these are doing just fine on the 3.5mm sight glass on this candlestick.  Though if any if these Bing Sight Glass' come under a 3.5 OD then they would likely leak.

Now I can put my Weeden seals back into the parts drawer!
