F E, with J as center, draw the plan K LM X. Also in its proper position draw the section on A G as O P R S. Now draw the rear elevation making G1 U and G1 V each equal to H E, and 1" T and 1"-1' each equal to C D. Project a line from B in side, intersecting the center line in rear at 4' . Then… … and wire allowances by D1 D2 E2 E1 and needs no further explanation. The front part of the pail shown by A B C H F G will be developed by triangulation, but before this can be done a true section must be obtained on B C, and a set of sections developed as follows: Divide one-half of 1' 4' T in rear…
