I considered several options, but decided that the box beam would work the best. Nick's book seems to recomend that but even without that, the time involved to make the box beam is slight compared to the trouble you might have with out a strong strongback.

: I would like to get a couple opinions from builders that have tried the 2
: main
: strong back styles. 2X4 up the middle of the forms vs. the big long plywood
: box type.. pros and cons??????
: Tks Rick
