My solution for the jack problem was to buy two jack stands, cost about $15
a pair, two 1.5ton hydraulic jacks with a lift of 8.5". Cost $16 each. All
this in Canadian dollars. $47 Canadian is $30 US more or less
The next step was to lengthen the legs of the jack stands, using angle iron
welded to the existing legs. This provides the height for the jack to sit
under the sliding vertical portion of the jack stand. Finally weld the
legs to a square piece of 3/16" plate. Bolt the jack directly under the
central vertical sliding portion of the stand.
You have to put a pad on the top of the jack stand. I used a piece of steel
plate with a thick softish rubber pad to accomodate the fact that the
underside of the plane is not exactly a level surface. I also used the
jacking points specified by Lancair with the holes for the locating pin.
The jack stand has a ratchet on it and therefore locks in place with no
chance of an inadvertent descent. 8.5" is enough lift.
Cheap, effective safe. I have used it for gear retraction tests and general
use.
