Blue sheet metal.

Michael S.:
Hello everyone,

I have a question about the sheet metal covering of steam cylinders.
Stuart engines only offer this black aluminum sheet metal these days. I often use brass sheet metal. But the correct choice would be blued sheet metal. That is, steel sheet metal that is heat-treated. I know the sheet metal needs to be polished and free of grease before the heat comes into play. But how do you do it exactly right?
I'd like to do it this way on my Stuart No. 7.
(Maybe Sanjay on his No. 5 😉 )

Hello Michael

'Russian Iron' was the traditional material of choice for cylinder and boiler cladding. I don't think it has been manufactured for years due to low demand. Brownells are well known gunsmithing suppliers, they sell a variety of chemical blueing/blacking kits for gun barrels etc. which may help you to produce your own faux 'Russian Iron'.

Cheers

Mike

I agree the blued lagging looks much better, I have 'blacking' chemicals for brass but not seen 'blueing' chemicals. The Stuart lagging these days is Ali painted black isn't, so not sure if you'd have to use copper sheet and then blue that?

crueby:
There are a number of chemicals available from the gunsmithing market, though they only work on certain metals. There are a lot more available from the jewelry industry, a whole range of colors that can be applied to copper/brass/etc.
