Stuart Steam Boiler Feed Pump (SBFP) - Stuart gasket material "Copperite" and "Oakenstrong"

[comstock-friend]

The drawings for the Stuart Steam Boiler Feed Pump (SBFP) calls out material for the three pump gaskets as "Copperite" 1/32" thick.

Google search turned up nothing. Is this just soft 1/32" thick copper of something fancy?

Also, the cylinder gaskets are called out as "Oakenstrong". Obviously, this must be much better than the oiled manila folder material I used on my D10!!! Any ideas of what this material is?

Oakenstrong is a trade name of gasket paper and still available https://jointine.co.uk/oakenstrong-gasket-paper/ Still sold by Stuarts too.

The Copperite was also likely to have been a proprietary gasket material, soft copper washers as sold by most model engineering suppliers will do the job for the two plugs. This is the type of material that would have been used on the flange, copper outer with a fibre filling sandwich https://www.heritagesteamsupplies.co.uk/gasket-sheet-jointing/copper-clad-gaskets.html

"Oakenstrong" sounds like a character out of Tolkien

Jasonb, thanks for the knowledge. Stuart calls out a rectangle of 'Copperite' so up to the builder to shape (two washers and one flange) and drill or punch. So no copper bead around the port like you'd see on a head gasket for instance. I have a buddy with a desk top laser. He did sets of D10 and Bill Harris Steam Roller gaskets for me and my building project friends. Maybe I can get him to do a set for these in copper sheet and manila folder material.

I make copper gaskets from domestic plumbing pipe.
Cut the required length, slit along the length with a hacksaw, flatten out and re-anneal.
