A follow-up on this...since this is to install the wheelpants and gear leg fairings, the aircraft needs to be in level flight position. What's the procedure used to get to this attitude? It's one thing to jack up the front of the plane this way, but there is the added complication of getting the plane longitudinally level (and keeping it that way during installation)...

I'll be the guy helping with this, so I'm following this thread with a keen eye towards *not* doing something that creates an unstable (and possibly even dangerous) situation.

(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!)

Default Dual wing jacks it is

I'm still thinking 3-point jack. Tail on stand and two wing jacks (with locking rings) on the firewall via 4x4. Given the distance of the jacking points this is about as stable as I think you can get without the wings on the plane.

Small price to pay for a plane that looks as good standing still as in flight

Default Lifting RV

Two weeks ago my wife and I put axles, wheels, brakes (and shims) on out -8. Without tail and wings the airplane is nose heavy, so tail was strapped/weighted down while lifting the front with an engine hoist and towing strap around the engine mount. This was well-controlled and very easy to do. Tail wheel went on fine after cleaning a bit of corrosion from the 9 year build (so far). N9669D (from our anniversary) is now at EAA Chapter 1158's beautiful hanger - exciting. Good luck with your installation.

Default Another Way

I'm just getting started on my wheel pants and needed to get the weight off the gear. I didn't like the idea of jacking against the firewall flange, so I came up with a way to jack against the engine mount.



I inserted a 1/2" socket extension through the hole in the top of the Harbor Freight Jack and then wrapped a piece of MIL6000 hose around the socket extension. I placed this under the fork at the top of the gear leg mount tube.



Here's a shot looking up from below:



The only disadvantage to this approach is that the cowling can't be installed, so it can't be used to install the upper intersection fairings. It will work great however for installing the wheel pants, gear leg fairings and lower intersection fairings.

Default Use the spar?

I built an accurately level sawhorse and placed it under the spar carrythrough. In this position the nose will be heavy so a lift on the nosewheel or (for this thread) a weight at the tail is required to get the craft longitudinally level. Since I could, I used a small car jack under the nosewheel pivot nut.

Sorry no pics, but for my 7 I raised the tail onto a table with blocks and slung tire chains over the tailwheel for wieght. I then built a saw horse to go inbetween the fuel vents under the firewall that was an inch or two short of touching the belly. The legs of the sawhorse look like the typical A, and I put a bottle jack under the horizontal part of the A. It made it easier to lift/level with the 2 jacks and then shim under the sawhorse legs to hold it.
