Abstract
A portable apparatus for forming an air turning assembly comprises upper and lower rail retaining tracks which are yieldably biased toward each other. Vane distorting chisels are mounted in spaced relation below the lower track and a staking assembly, movable longitudinally so as to sequentially register with the chisels, is mounted above the upper track. The staking assembly is shiftable toward the fixed chisels beneath the lower track whereby edges of a vane temporarily mounted between the rails may be staked in a single operation to both rails, downward movement of the staking chisels being effected to deform portions of the vane above the upper rail, such downward movement also functioning bodily to shift the rails and vane downwardly, such the portions of the vane below the lower rail are deformed by the chisels below the lower rail.
