Today I did get some shop time in and even though I didn't make that much headway I will post what I have. Aside from making some nuts and starting to mill the bearing blocks I did get the detent plunger all made up and the indexing arm and acorn nut.
This photo is the odds and end pieces for the swinging latching Bar. The adjustment nut, latch nut, and rocker washer.
The Acorn nut and knurl adjustment screw
I started the Plunger sleeve by first cutting it down to size then cutting the 1/2x56 threads on the lathe. I removed the collet chuck from the lathe and mounted it on the RT on the mill and cut the 3/32" groove and offset plus the two flats.
Next I made the plunger knob by turning to size in the lathe cut the two grooves and drill the center to depth and finish with 1/8" drill bit straight through.
I didn't get a shot of the plunger being made it was just straight turning except the curve on the end which I used a profile tool to cut. This is the detent all completed.
Next I milled the indexing arm by first drill with an undersize bit along the perimeter and finished with final size mill.

I started to mill the small bearing blocks. I set them up in the mill as true and straight as I could get them. Used the edge finder to locate the two edges and centered the mill and cut the 3/16" x 1" slots down the middle. I used and 11/16" end mill down the center and finish the width to 1" with more side passes.
After Milling the 1" slot I inserted my punch from my optic punch set and scribed a line down the middle of the groove for reference when marking out.
I layed the bearing block on the surface plate and scribed in the lines for boring on the lathe later. I also center punched the crossing lines.
That's about it for now, like I said yesterday my job is starting up so it will be a week or so before more progress on this. Thanks for following and commenting.
