That part of the bottom that cleared the water, at the bow and under the stern, was often made of tongue-and-groove planking, or else the seams athwartship would be splined.

The tool-heads are moved horizontally by the screws _H_ and _H_{1}_, and the vertical feed for the tool-bars is obtained from the splined shafts _V_ and _V_{1}_, there being a separate screw and shaft for each head so that the feeding movements are independent.

The feed screw is splined to give an independent feed, and the swing frame is operated by a worm as shown.

This vertical feed shaft carries a splined worm driving a worm-gear splined on a horizontal shaft which is carried by the knee, which has a projecting arm or bracket for carrying the back end of the shaft, so that the latter rises or falls with the knee.

There should be three of these bearings, one at one end of the head, and as close to it as convenient, another at the other end, as close as will permit the insertion of the cutters, and the third as far from the second as will permit the insertion on the bar and between them of a pulley to drive the bar, which must be splined to receive a feather in the pulley, so that the bar may be fed through its bearings and through the pulley to the cut.
