Tomorrow is a holiday here in the States and the company I work for gives this off to us. Since it fell on a weekend day they gave us today off.

Since it is my birthday and we have a threat of rain I didn't do any staining on the cabin today....instead I made some great progress in the shop on the reciever.
I was having some trouble getting things concentric. After bluing up the register I found that when I tightened up the receiver pins the chuck would be pulled slightly off center and would not let the chuck sit tightly on the face.

Ok...so back to the mill, find center again on open up the holes about .010. PERFECT!!!!.... Before doing this I noticed that my 5C collet chuck was the only chuck that would fit fairly well in the holes. The rest would not drop down low enough because of binding. What I found after checking the bores for the pins on the lathe reciever that they were made for a very sloppy fit. Now I have just slightly over .001 TIR with it mounted in the 4 jaw and when I finally fitted it to the rotary table I have the same results with a .75 dia rod held in the 5C collet chuck. I am more than pleased with this as I was shooting for no more than .003.
Here is the 5C collet chuck mounted to the reciever. It measured .001 + TIR here.

Here it is mounted on the rotary table with the same TIR.

Here are the other D1-4 chucks and face plate mounted on the reciever:

Obviously the height will be a problem for some, luckily I still have plenty of room left and now I can mount any size d1-4 chuck to the rotary table.
I still need to make the detents for the pins so that it is easier to locate where the pins are set to remove the chuck, I have been kicking around the design of the pins quit a bit with circlip via skype and I will be cutting a grove all the way around the pins. Spot drill where I want the detent, then use a metal ball and spring with a grub screw to push the ball into the detent.
Crap-O-Cad drawings to follow.
