I always wondered what the Super Bowl actually looked like....
At first glance, I thought it was connected to the PTO, but it appears to just replace a rear wheel. Begs the question.....
What came first, the bowl blank mounting or the positioning of the 'lathe'.
I used to have a link of at least 13 to 14 years ago of numerous places in Eurasia that used motorized vehicles - farm tractors as the power source for turnings, including huge bowls like the one in the link. Amazing ingenuity!
