Dave,

        What you do is to remove the pant. next, you remove the nut plate

adapter from the nut leaving a (I believe a 11/16") hole.  You put a

pipe, about 12 to 15" long into the hole and put a jack on the end of the

pipe.  Jack the wheel up and then remove the nut (hopefully you pulled

the key and loosened it a bit before you jacked it up) and slide the

wheel outward on to the pipe.  Once the wheel is removed far enough, you

put a stand under the axle and let the jack down.  Remove the wheel and

pipe and do what ever.  

        I modified my axle nuts to do this in the future.  There is not a

good way to do tire repair or what ever with the fairings in place.  I

did not relish lifting the a/c at the wing.  Its a cheep mod.  A piece of

pipe and a small jack with a jack stand is all you need.

The problem I had with this method was the height of the pipe to the floor.

I didn't have a jack that would get under it.  Even my floor jack was too

low so I went with the avery system.  Both use the same principle however

and it works great.

Dave,



  I got this somewhere. Whoever came up with it should realy get the credit 

but I don't know who that is. It seemed simple enough to duplicate that's 

what I planed to do.

Yes,

 Works as advertised. I got one of these a week ago and was able to easily change a tire with no swapping of jacks, blocks and so forth.

 While its an expensive little bugger, im hoping between my use and loaning out to buddies, it will pay for itself. 

 

 No reason why it would not work on all kinds of planes too. The pipe in the axle method requires a hollow axle. This gismo does not. 

 Link to site here that sells the "handy Jack". Site d/l time is ridicules for some reason.

 Best,

I sense a reluctance by some to use a wing jack. I  have been using a wing jack on my 6A since day one. Is there a problem with  wing jacks on RVs that I may not be aware of.

I use them every time I fly.  Without lifting my wings it would be no fun; plus I would probably hit the fence. <grin>

I have been using a wing jack, but am going to change to the cable/lever type on axel. If sh__ happens it will be less to repair. Accidents are never planned, right?  

Happy landings,

 You want your airplane to be nose heavy when you jack it up by the jack points.  That means the CG is where it is supposed to be.  Remember aerodynamics 101: the wings lift and the tail gets pushed down in flight.

Huh??(at)*&??



I have been jacking my RV up for five years at the tiedown points and 

never has the tailwheel left the ground.



I must be violating aerodynamics 101, of course I do not believe that 

Bernoulli was right!

I'm not sure why Bob with the RV-6 has not had a problem, although maybe an RV-6 is different in this way. 



I think my cg is right where it needs to be. I looked at my weight and balance charts and found out:

 

The main gear wheels are at 68.76"

CG of plane, no pilot, with half fuel is 77.8. Since this is aft of the mains and forward of the tail wheel the plane sits fine on the ground.

 

Since the fuel cg is at 80", and the jacking location is aft of the fuel, I would guess the tie down/jacking hole is about 85" aft of datum. I'm not at the airplane so am just guessing at this. 

 

Since the jacking position is between the cg and tail wheel, it takes load off the tail wheel and will ultimately lift if off the ground.

It is a non-problem if you do one wing at a time.  It is when you do both 

that the tail comes up.
