A rotary cutterblock for woodworking machinery has a body made up of a row of discs (10) of different diameters. The disc diameters are chosen to approximate, as far as possible, the profile of a timber moulding to be formed, and discs can be selected from a stock of standard sizes. The use of spacers (22) between adjacent discs enables the mass to be kept to a minimum. The cutterblock is quiet in use, especially when blades clamped in successive discs are staggered around the circumference of the cutterblock. A preferred method of manufacture of such a cutterblock having staggered blades comprisises initially mounting the discs (10) on a mounting shaft with the blades (14) in axial-alignment for grinding purposes, and then removing the discs (10) from the mounting shaft and reassembling them in the same sequence but angularly offset one from another. |
