Neat idea, you have to give him an 'A' for effort. Now if he eliminates
the bending down to fasten a strap thing to something reachable *while
standing* then I'll give him an 'A+'.

Yeah, the weakness in that design is that the legs have to be held
together to hold the crosspiece in place--they want to go the wrong way
under load.


Looks like under a straight down load it is not going to want to push
apart because the top sits in a notch with the pivot point below.

Yeah, the tension strap is going to be necessary to keep the unit from
collapsing under any kind of wiggle and load.


After I put a set together this weekend I'll report back how tension
is on the strap.

There will not be much tension at all, it only needs to keep the legs
from spreading farther. BUT if you want a tight fit, the straps will
need to be tensioned quite a bit and any compression in the wood will
require further adjustment of the straps.

This is a cool idea but solid stops will be needed. Perhaps a board
that lays across the tops of the bottom rails that has stops on the
ends to prevent the legs from spreading out.

The big flaw here is that the more weight you add the more loosely
everything will fit.





I'm also not sure why the designer has the legs put together the way
they are. I would think maybe having the legs on one side be inside
legs and the other side be outside legs might also work. Maybe they
need to be that way because they splay out...
