I got the micrometer put together. It only took an hour and a half. :rofl: :rofl: There are also two little steel ball bearings somewhere on my floor , never to be seen again. 
anic: ( I was smart, needed two , bought six). I realize this don't look all that big a deal till you try to hold those two balls in the hole in the screw with the spring between them and put the thimble on at the same time. I spent most of the time looking for little steel balls that shot out and bounced off something and rolled away. The darn thing works great though. The balls ride in a groove in the thimble keeping pressure on it, tight enough to follow the screw when it is turned, but still easy to re-position for "zero" when desired. A thumb screw lock is not needed. I wasn't sure this was going to work, but I am really impressed with this design. ( sometimes it don't take a lot to impress me :nuts My wife was watching this ( I think she is still laughing)
The print will give you a vision of how it works. 
I really wanted to get the curved slots milled in the front plate. I did this on the rotary table. To make it easy, I went to my shop yesterday and set my lathe up to make an MT2 taper with a 3/4" blank end on it. Once rolling , I cranked out a half a dozen of them. They will be used as tooling for my rotary table. I chucked one up and turned a .375" stub on the end. The center hole in my rotary table is MT2. I chucked the stub in the mill spindle and lowered the spindle with the stub into the rotary table till it was snug, locked the spindle and tightened the clamps for holding the rotary table in place. Presto! it is automatically centered to within 1 or 2 thousandths. ( I read about this somewhere and it saves so much time). The hole in my plate is .375", so I just put it on the stub that I left in the center of the table, clamped the part down and it is set to mill. No indicator required. As you can see in the photos, I just cranked the mill table out the amount of my radius and milled the slot. the whole process took about 20 minutes. I will save this stub and make a bushing for what ever diameter I need and put it on the stub and my part is located as soon as I set it on the table.
