Well, another day of not riding my motorcycle while it's over 80ºF, but got (hopefully) the last of the M/C parts done so I can kill the next 10 to 12 shop hours making that Kondia machine part for Darren.
If Neil needs any more, it'll be up to him to run the machines himself, though only the lathe and surface grinder will be available.
Here's two 316ss washers, Ø1.420" x Ø0.320" x 0.100" thick, with a Ø.560" x 0.030" counterbore.
And a 316ss Ø1.501 x 1.344" long disk brake piston. The original, pictured next to it, was corroded badly where the piston is exposed to the elements. That causes repeated seal failures. When I picked up the original it seemed lighter than is should be for a solid piston, yet I could see no signs of welded construction. After making the new one, I asked the customer if I could cut the old one open to see why it didn't weigh any more than the one I made with a Ø1-1/8" x 1-1/8" deep bore.
After cutting into it with a Kennametal 3/4" 3-insert should mill, the "cover" popped out, jammed and busted an insert. I should be able to fix the cutter, but damaging the cutter for the sake of curiosity wasn't worth it. Hindsight is 20/20.
Neil has some photos of yesterday's work. He said he'd post them later.
