I built 2 jacks using:

          Older style short car jack stand plus a bottle jack welded to flat plate of jack stand.  2 each.  Old jack stands can be found at thrift stores or used tool places, or your garage if you're over 60.

          The older style jack stand has 3 legs and a top that needs to be pounded out flat.   To that place on it an appropriately sized hydraulic bottle jack (Harbor Freight); I drilled one hole for  a nut and bolt and then welded most of the perimiter.  Also weld the up-down adjustment and pin in the stand (the pin still takes the vertical compressive load, so welds are just keeping the "height" of the jack stand constant.)

           The top of the jack can be dremeled out to receive the pointy cone of the common jack point from Lancair (used on Mooneys too I think).

           When under the center of the ac, both jacks can be jacked at the same time for a level rise.   

           Tail is supported on a wood cradle that is held down with 3 sand bags or grain bags of 30-40 pounds each, and a strap wraps around the empennage just forward of the horizonal that is fixed to the wood cradle.   (Some put them on the horizontal stabilizer; not so good.)

           THEN place 2 "safety" carpenter horses under the wings at a rib that is padded (and I also contoured the top board to match the bottom contour of the wing).     Usually, I then lower the jacks slightly to have partial normal force on to the safety horses.    VERY STABLE!  Climb in and out all you want.

               Since my plane has a lot of yellow.... I cleaned the jack stand and bottle jack and sprayed it ... yellow.   Nice to grind out the C- welds before painting.

            I've used this simple and cheap system a dozen times now.    Only spent $8 for the one lacking bottle jack.  They have become indispensable. 

             Next trip to hangar I'll take a picture and forward it.
