I really have cracked on today. A lot more done, or started, than I thought I would. So to clean all the parts. Following some advice from, Roger Bean, I’m trying pickling the parts in white vinegar.
In a bucket
Small parts first. This is left to pickle for two hours or so and then scrubbed with a brass wire brush.
All the loose crud came off easily. The working surfaces came up like new and the rough cast was fine.
I gave the whole lot a rinse in warm water and a dry.
Then a spray with WD40, all over, to stop any short term rusting.
As it was such a great success I’ve put the two large castings in
and having topped the liquid up with water, and hence reducing the acetic acid concentration, I’m giving them a soak overnight. That really is all for today.
Be seeing you.
