Wolfgang,

Glad to see that your design has the "machine feet".  Some of the other designs on the LML have not and I think they are unsafe without the feet that go under the jack.  Whatever the stand is that will support the aircraft weight when the lift is complete must be firmly pressed to the floor DURING the lift, or there will be no lateral stability during the lift.  Thanks again for the pictures.  Mine is much the same except the auto jack stand is welded inside a larger steel pyramid shape with a large plate on the bottom for the foot.  It just took some surplus steel and a welder's time.

Ask Lorn Olsen for a picture of the jacks I made up for him using standard car jack stands, bottle jacks and machine feet.
