supported above a work path by a travelling hoist 13 which provides both horizontal and vertical movement to the perforate basket 11 as indicated by the arrows in fig1 interposed between the perforate basket 11 and the travelling hoist 13 is a reversible spinning assembly 15 with its control handle 16 in the initial steps the perforate basket 11 containing the parts to be coated is lowered into tanks 17 containing a pre coating solution or pickling rinsing and fluxing solutions in this respect the basket can be spun while it is dunked beneath the surface of each of the solutions after leaving the pre coating tanks 17 the perforate basket 11 is spun until its contents are preferably dry and then it is moved above a spin coat tank 19 where it is lowered into a molten zinc bath covered by a flux as the perforate basket 11 is lowered into the molten zinc the flux is skimmed from the surface and the perforate basket 11 is spun first in one direction and stopped and then spun in the opposite direction by the reversible spinning assembly 15 after the coating is completed in the spin coat tank 19 the rotation of the perforate basket 11 is stopped and it is elevated from the spin coat tank 19 the basket is then moved over the spin quench tank 21 where it is lowered within a shield 23 which surrounds the spin quench tank 21 it is.
