The new articulated head Flexi hollower from Woodcut Tools is designed to work on small to medium vessels and it excels at this. It will comfortably fit through a 15mm aperture due to the 12.7mm (1/2") diameter shaft and no steps in the linkages. The tool is supplied with two links, a straight and a curved which are made from high tensile steel to maximise rigidity. The cutter head is a smaller version of those used on the larger Pro-Forme hollowing tools and it is made to the same high specification. It is not a difficult tool to master and the depth of cut is easily adjustable. If you try it out on some open vessels first, you can see what is going on and how best to present the cutting head to the work. This will make things easier when the the cutting head is out of sight in a hollow vessel. For use on small to medium sized projects with a depth of no more than 6 to 8 inches, the achievable depth depends on the size of the opening and the type of tool support used. Supplied as unhandled with an optional twin collet handle available to make a truly versatile tool.
