Curtis,
    A welder angle iron stand for the bottle jacks has a weight advantage.
However, I have my jacks strapped to the angled cement blocks the Home Depot
sells.  They are heavy, but make a very solid platform for the jacks, and are
very inexpensive.
    Also... I found that the jack points, as described in the manual, were not
sufficiently reinforced.  I use a padded 2 x 4 between the two jacks.  The 2 x
4 is just shorter than the distance between the inside gear doors and is placed
just aft of the nose gear door.

[I originally built a nice solid wood pedestal to hold my bottle jacks,
screwed them to the top of it and was convinced that it was a good and 
sturdy setup.  Much to my chagrin I came into the shop one day to 
find the entire airframe setting down on its nose... a slight movement
had allowed one of the jacks to tear itself from its base, the whole
thing collapsed and the base of the jack punctured a 4" long gash into 
the fuselage bottom where it had gotten pinned in the process.  I
immediately built the one-piece all steel structure as shown in Jens' 
photo and have slept much better ever since.  I would think more than 
twice about having a bottle jack up in the air if it doesn't have a 
very wide base welded to its bottom... the possibility of it moving must
be completely removed.   FWIW....     <Marv>   ]
