Here's how I did it on my 6. Used the bottle jack and a 4x4 block to lift and then rested it back on the 4x4's on the jack stands. Jack and stands courtesy of Harbor Freight.
kinda what I had in mind myself. I built a couple of wing jacks with the same cyl. I was thinking of pulling the exhaust though. I figured if I lifted the tail first that this might be a way to get it done.
(As an aside, this is one time I get to tell my taildragger friend he should have built an -A model since it was considerably easier with my -7A LOL!)
