And then I started varnishing the insulating blanket material with Glyptal. It soaks into the fiber, so the varnishing took most of the day. All three boxes got a first coat.

It looks good. I plan to put a second coat on soon, whenever it's warm enough again. I also want to put at least one coat on all of the covers,
but that can wait until warmer weather. I should probably also coat the covers on the 309 sometime. DB-15 arc chutes open straight down, so the cover should be the only target of normal arcing, unless something really goes wrong.
And I did some rechecking of the electrical circuits, and cleaning and straightening in the workroom. And talked to Rod about getting the parts we need, such as new rubber washers. The picture above (R) gives a good view of the 1/2" bolts that hold up the contactors. We need new rubber insulators to support the contactors, and this may not be easy or inexpensive. But Rod will certainly be able to find a solution.
