Here's the last pass on the final diameter at 3.90 inches OD. This is what will stick out in front of the face of the primary to attach the Baffold Tube.
The first shoulder in from the end will get turned to 4.10 inch OD in the morning when it's cold and then turned at 20 TPI to fit the Nut we made yesterday.
Then we will turn it around again and turn the short section that fits into the Back Plate with the O-ring for centering.
Until tomorrow.
Regards,
Preston
