ABSTRACT:
An apparatus for mounting a device, such as a saw blade, on a base (3) to enable the blade to be positioned accurately in either of two distinct positions relative to the base. The apparatus comprises a pivot member (21) for supporting the blade (not shown) pivotally mounted on a fixed member (11). The fixed member (11) includes a pair of abutments (142,144) and the pivot member has at least one asymmetric stop (160) for abutting the abutments (142,144) after rotation of the pivot member (21) relative to the fixed member to define the distinct positions of the blade. These positions are defined generally by the positions of the abutments (142,144) and accurately by the orientation of the or each asymmetric stop (160). The apparatus may further include a device (170) for adjusting accurately one of the distinct positions by a predetermined amount.
