A Prototype Adjustable Aperture Disk, Part 2

On I go...

Finding the edge.

Spot drilling the pivot hole.

Counterboring one of the two screw holes with a twist drill, which is less than ideal. I wish I had a #2 counterbore...

Getting there.

Drilling the pivot hole in the other half of the body.

Drilling screw holes.

Tapping #2-56.

Boring out a recess with a 1/2" end mill.

Enlarging with a boring head. Boring doesn't work well on the Taig mill but I've already figured out how to do it easily on the lathe...just need to make a faceplate fixture. Like I said, this one's a prototype.

Test assembly.

Blurry shot of winding a spring from a, well, spring. I didn't have any .01" dia wire handy.
