Re: SB: Temporary Supporting Walls

["Douglas L. Roorda" <douglasr@softhome.net>]

Without reflecting on whether it is a good idea, if you wanted to do that 
you could borrow the jacks that they use to build steel grain bins. They 
are built buy assembling a single 3 foot tall ring, building the roof, then 
jacking it up enough to bolt on another ring underneath, doing this repeatedly.

Structural issues would be quite different perhaps since the flexible bin 
deforms quite nicely and safely in response to uneven jacking, whereas a 
rigid roof structure is, well, rigid.
