An Al Basham turning tool generally refers to the specialty woodturning and hollowing systems manufactured by the late Al Basham. These setups are highly regarded in the woodturning community for hollowing out vessels and hollow forms. The Al Basham hollowing system is characterized by:Stabilizing Outriggers: A core feature of the system is the use of outriggers (or stabilizer arms) that attach to the tool to counteract rotational torque and prevent severe tool catches. Versatile Reach: The setups were designed to help users effectively hollow out vessels (often 8 inches or smaller) without the intense physical strain usually experienced when working with freehand tools. Customization & Parts: Since these systems are no longer commercially manufactured, many turners who use Al Basham bases opt to build, couple, or recondition secondary pieces-like D-shaped followers or boring bars-to complete their rig.
