A few of you were curious to see pictures about my titanium-ring adventure.
Some of these pictures were made by Norm. Thanks Norm!
The source material:
had a friend that said. "It looks like it was made by someone that almost knew what they were doing!"
The runout resulted in a difference in concentricity between the outer and inner diameters of about 0.005"! However, it kindof looks intentional!
In the picture above, you'll see some markings inside. That's a combination of the chatter-marks from the boring, and leftover purple from the torch that didn't get removed in the troughs.
