Mark on the sides the position of the channel. Fit
the wood material to the curve of the side, shaving its bearing surface
until the channel lies level with the beam of the ship. Now cut the
notches, thru which the chainplates will pass. On large ships a batten
or capping strip of wood or iron was laid over this edge, holding the
chainplates in the notches, Fig 18. To better hold the channels, drill
them (about No.75 drill) so a pin may be thrust thru. Pin and glue in
place.
On the later and larger sail
ships, double channels were common. Fig. 19.
