The First Article Was a Learning One but Still Adequate

The release agent on the 6-32 screws used to position the threaded inserts was sufficient.   They unscrewed from the inserts easily.   I then put in the .130" long socket head 6-32 screws.  These lock down the outer race of the bearing and leave enough slack to lock this all down to the axis housing.   

You will notice one screw is not quite square to the block.   I will be more careful about positioning on the other three blocks.   Three screws are sufficient to hold the bearing in place in the block.   All four will hold the bearing block in the axis housing.
