Pouring a footer and am placing re bar. How do you hang the re shaft in the center?
Answers:    They make chain stands that the rebar lays in. Lowes, Home Depot. Just tell the Mill Wright what your doing, they will tighten you up.
you in fact prob it up from the bottom with short pieces of rebar.
although you could conceivably hang it from a board across the concrete forms using line... Pillow blocks and tie wire.
