Most of us are do-it-yourself kind of guys so I see the appeal of building something that looks easy and would save a few bucks.  Considering the experimental angle, (might work fine, might not).   I bought a pair of model 326 jacks from http://aircraftjacks.com/   for $179.00 each.  They are very stable, easy to operate, have locking collars and are light enough to pick up and carry around easily. 

I rationalized the purchase as: A. One more thing I would not have to build before first flight and  B. Reduced the possibility of putting a 4” diameter drain in a fuel tank.
