The standard Sherline lathe can accommodate parts up to 3.5" (90 mm) in diameter. However, there are times when you may need to work on larger pieces. The Sherline headstock spacer block increases the lathe’s maximum working diameter to 6" (152 mm), significantly expanding its capabilities.

This set includes a 1.235" (31.37 mm) spacer block that fits beneath the headstock, along with a riser-rocker tool post to elevate the cutting tool accordingly. If you plan to turn parts between centers while using the headstock riser, you’ll also need a tailstock riser block to maintain proper alignment.

Note: Although the spacer block allows turning parts up to 6" in diameter, the lathe’s motor power remains unchanged. This accessory is best suited for machining easy-to-cut materials or for occasional use when extra clearance is needed. If your work frequently requires this added capacity, upgrading to a larger lathe may be advisable.
