Hi
Thx for your comments. I will clean up the surfaces and lightly oil them with hydraulic oil. I have made some new gaskets with Flexoid gasket material which I have used before with zero corrosion issues.

It was stored in the same drawer next to the flywheel which is waiting for final bore and keyway. The flywheel surface is highly polished, and though very slightly tanished shows no sign of rust or corrosion.

Its a bit of a puzzle really .. .

Many thanks for your interest and suggestions.

Best Regards

As you can see this is a serious attack of the brown stuff, not just a bit of damp. All the surfaces were good before storing, and the nuts holding the chests and cylinder ends were tight. That should have excluded any oxygen. The gaskets on the cylinder ends were stuck to the surface. No sealant was used, as I knew it would come apart again before final assembly. I would have been better off leaving it in the garden shed .. .

There was no obvious dampness in the gaskets, which were used straight from the kit box.

I intend to replace them with Flexoid gasket material, which I have used before, unless anyone can think of a reason not to.

I have never had rusting like this on such a short timescale with such severity.

Bit of a puzzle really

I am building a Stuart Victoria Stationary engine.

Having completed the cylinder and steam chest about 3 months ago these were stored in a draw. I have just taken them out for final fitting to find that everywhere which has gaskets is rusted, chest and cylinder endplates, but only where the gasket touches. The bore and all outer surfaces are all rust free.

Its as though a chemical in the gaskets is causing the rusting.

Any ideas on what this problem is? I can't believe Stuart would knowingly supply incompatible gasket materials.

Any Advice much appreciated.

Would post pictures but I can't seem to do it .. .

Best regards
