Fig. 16.

First draw a side elevation of the desired vessel, D E, then from A as a centre describe the arcs C D C and G E G ; after finding the diameter of the top or large end, turn to the table of Diameters and Circumferences, where you will find the true circumference, which you will proceed to lay out on the upper or larger arc C D C, making due allowance for the locks, wire, and burr. This is for one piece; if for two pieces, you will lay out only one-half the circumference on the plate; if for three pieces, one-third; if for four pieces, one-fourth ; and so on for any number, remembering to make the allowance for locks, wire, and burr on the piece you use for a pattern.
