BarbeeQ - Cool machine. Sorry for the delay in responding. I am spending most of my time on the VSS forum. Not sure how much help I can be since mine just required cleaning, and then cleaning, and then some more cleaning...
I use Sewing Machine Oil on the painted parts and brasso and/or 0000 Steel wool on the metal bits.
I would be glad to try to answer any questions you may have after reviewing the documents that Jon shared the links to.
The key is clean, and no particulates...
