: After pricing aluminum for a strongback on my current project, I retreated to
: steel. A 2"x2"x16' chunk of square steel tube with 3/16"
: wall thickness was $50 +/-. The best price I could find for sluminum was
: $4/lb., and anything suitably rigid would have been well over $100.
: Besides being cheaper, this tube is stout enough to hold up a house.

: The mold blocks are 1"x1"x3/16" angle iron, bolted down with
: 2"x5/16" square U-bolts (sounds like an oxymoron, but that's
: what the hardware guys call 'em), so they're easily adjustable, easily
: scalable for different boats and/or station spacing, and stout enough to
: use for a ladder. I'll try to get a picture up soon.

Well, here goes...
