I like a project, but not planning to start this one until next year, however I wanted to give the vinegar rust removal a go, so I thought I'd try on the escalator.
Like everything else, it was seized solid, so I bought some of Asda'a finest white vinegar & had a go.
A couple of pics of the escalator, before I started. Took it all to pieces, carefully removing the various levers that had seized onto their pivots, poured the vinegar into a plastic container & mixed in a few tablespoons of salt. Put the parts in, leave for 24 hours, then give them a gentle scrub with some wire wool.
Not quite as good as new, but I'm pleased with the result. Made a new rubber stop out of an old pinball machine rebound rubber, re-built the escalator, & it works fine.
Just need a main spring, if anyone has one to sell. P.S. If you try this, wear gloves & try not to spill any vinegar on your bench. It stinks!
