Larry, the hole should be concrete lined just to keep it from caving in. The support comes from a 4'x4' frame embedded in the 12" thick concrete floor that attaches to the upper rim of the lift cylinder. Cost me one Mexican jack hammering and digging for a day, half day of forming and rebar and 4 yards of concrete. Best way to come up with a lift is if you see a station being demoed, something that was going on a lot when I scored mine but you don't see much anymore.Originally posted by LarryB
Bill, that's what I was thinking of doing. I have a 16' ceiling in part of my shop, I could even get the motorhome up enough to walk under it. I'm gonna start looking. How complicated does the hole in the ground need to be? Concrete lined?
