Further thoughts... test the 2x4 jack stick by placing one end on a bottom sill of a framed/stood/braced wall, other end on floor- pushing down on it with some force to see if it will crack or break, better now than in middle of the raise. Mark it so you don't use it for something else, use them on all the jacked walls. Nail a 16" 2x4 flat on the deck after installing jack w.2x, nailing 5-6 times if between joists, not hitting or two times each side if in joists- to back the jack from sliding. Then shoot/drive 3 -10d nails at right angle and 1" up from end of jack stick, into floor decking, as they stay only if the 2x's are long enough without falling off header when wall is plumb. If sticks are too short, don't nail the bottoms at all- add another flat 2x on top the other for higher back bracing for jack stick. The man operating wall jack can help gently push the wall as it is almost plumb, dragging with down pressure the jack/stick (if not nailed) remainder till plumb- keeping pressure against the header, same as another guy controlling the other two tall semi-permanent braces already fastened at top only when 4' off deck. IF really heavy, before sheathing the wall, nail some 2x blocks (10") every 16" away/in-line (between studs) where the brace stick will be- using these as safeties (floor blocks) to prevent wall from fallen back on personnel during the lift. If you have 4 headers, two jacks may not be enough, how long/high is the wall?
A frame wall with 6x6 every 6' for windows (6x10 headers, 4x6 sills and 2x6 studs) and 32' long, 18' high is max for 4 jacks, glad I'm retired now... lol.
PS- any questions? you have to know exactly what to expect.
