Do it yourself foundation lift

[Me2]

G'Day Frank, thankyou for looking in and commenting. I spent a bit of time on Inventor to get everything working right and had 90% of the parts laser cut from the generated DXF's. Didn't take long to knock up and worked better than I had hoped. Mine was small sized compared to your units, 12 ft diameter and a 36 ft Bell Mouth. Now that's some serious work, would love to see something like that in action, the drive unit must have been huge.
