A spinning or twisting spindle is formed of a one-piece metal spindle top having a spindle shank and a whirl formed of a die cast aluminum alloy, and preferably one containing more than 12 percent silicon in crystalline form. The spindle is formed according to preferred methods whereby the spindle top is die cast so as to produce a spindle that is overized relative to an intended final size, the cast spindle top is machined to its final size and a fixed connection is formed between the shaft and the spindle top. The connection, in one embodiment, is created by press fitting the shaft into an opening cast into an end of the spindle top, while in a second method, the connection is formed by die casting the spindle top about the shaft.
