The combination shafter is a precision tool manufactured in Germany. The shafter can be adjusted for any shaft diameter with a detent function. As a result, shafts with all three common diameters (5/16, 11/32, 23/64) can be compressed and exactly calibrated in the process. The wooden shaft is compressed to a precisely defined length and to a precisely specified diameter, and is now perfectly adapted to the Bearpoint tips. After the compressed section of the wooden shaft has been coated with epoxy resin (e.g.UHU 300 endfest), the degreased Bearpoint tip is pushed over the shaft and ends flush with the exact outside diameter of the shaft.
