	Workpieces cannot extend more than 4 to 5 times their diameter from the chuck or they start to wobble and whip. With care it is possible to make cuts at such extensions, but heavy cutting work needs to be supported by a live centre in the tailstock.		Workpieces in [[Haas ST-15Y\|the lathe]] cannot extend more than 4 to 5 times their diameter from the chuck or they start to wobble and whip. With care it is possible to make cuts at such extensions, but heavy cutting work needs to be supported by a live centre [[Tailstock (Haas ST-15Y)\|in the tailstock]].

	The tailstock is a hybrid manual-hydraulic design. The body of the tailstock must be brought forward toward the chuck, and then the hydraulic quill should be extended so the live centre tip rests securely in the seat created by a centre drill.
