I made a trip to home depot today and found the supplies.
I used a self tightening ring found in the plumbing isle. I grabed a few sizes, the largest size works best with the L series lenses. I headed to the nuts and bolts isle and grabbed a 4" Eye Bolt with a few nuts to tighten. I used a high density foam tape as a protective shield on the inside of the metal ring to prevent over tightening.
At home, i took some metal clippers and cut open two of the notches in the metal ring for the bolt to fit in.
I used some metal super glow in the inside of the bolts to prevent loosening.
Here is a few photos of the finished Follow Focus.
