A work bench (10) including at least two work piece supports (57), the two supports are positioned at intervals along an elongate member (24) and define a substantially horizontal plane in which a work piece can move, a mounting (20) for a power tool (12), the mounting is affixed to the elongate member and can rotate about an axis that is substantially parallel to the length of the elongate member, a ground engaging member (106) which supports the power tool mounting at a point spaced away from the elongate member and adjustment means for adjusting the effective length of the ground engaging member.
