I spent all weekend polishing and cleaning the small parts. I will post a picture tonight. This is definitely time consuming. I still have not sprayed the paint on the casting. I needed to do some research first to make sure etching primer would not be an issue.

It's a bit late now, but some polished are very effective on the shiny parts; needle and presser bar shine up like new with something called Quick-Glo, in just a few minutes with hands, a cotton rag dipped in a bit of the paste; rust, grime and tarnish comes very effectively. Paste type polishes seem to be more effective than thinner liquids, at least the stuff I have tried. Pol and Autosol work well too, I'm sure there are several, and it's worth tracking down the brands that work well for steel and chrome. I have yet to pick a machine completely appart, I hope to avoid it, but once off I guess the cast iron rods and hinges clean up much easier too.

I also like pastes better. I use Mother's. It's a lightweight paste and it works very well on dark splotches and that whitish hazy film on plates and flywheels.

Well I have been super busy with a ton of projects. Here are the updates I promised. The Machine body has been sprayed with 3 coats of etching primer. This was allowed to cure and off-gas. The next step is to lightly smooth with 000 steel wool and then fill in any casting voids with a quality 2 part filler. After that it will be primed. I am using Krylon products for the paint as that is what I can get locally. I did not mask any of the areas on the machine. I will use a Dremel with a wire brush to remove the paint from the areas that need to be bare metal. This ensures total coverage of any exposed areas. and a much cleaner look when completed. It is an extra step, but I am not in a hurry.

It will be nice to see its progress. Makes me appreciate the work that went into my old machines

It has been some time since I have worked on this but this week, I am going to prep the base for paint.

About how much "help" did you need to drive the pins out? I can get the pin out on one of my 15-91s but not on the other. We did check for a taper. Just curious how much convincing you wound up using on your machine. Thank you.
