<p>An apparatus for milling the surface of low slope substrate has a milling device, such as a saw, and a track along which the milling device may move. The track is supported above the substrate by a plurality of adjustable supports which have adjustment means for orienting the track vertically or at a desired angle to horizontal. A mounting assembly for the milling device has means for engaging the track and enabling movement of the assembly along the track with the milling device depending from the mounting assembly. Adjustment means coact with the milling device and the mounting assembly enabling the device to be oriented in a desired manner relative to the substrate.</p> |
