DCD as shown.. CABD, Fig. 117, is the curved half of the rudder trunk. DEFB is the part which is fastened to the stern post and is found by measuring from the line BD the line of the stern post. The part project- ing beyond EF is the flange for con- i ey | esl y necting the trunk and transom to- gether. The width of the flange is measured from BAB and -.DCD .as fc ie. shown by AA; and CC. "sary to get the true form-of the trunk on the shell plating so that the holes It is neces- | ee / re, "TAE MarRINeE REVIEW may be punched in the shell and the hole for the rudder stock cut out right. Fig. 118 shows the method of ob- taining the true form of the trunk opening through the shell. The line'CD is longer than EF, and df Lope Lolo? is fy / ae J noes the lines 1 to 11 are erected perpen- dicular to EF dividing same equally on CD. At right angles to CD.the lines I- to a1 are extended . long enough to get points equal to the dis- tance I-I, 2-2, etc., from the line EF. _ _ Distance from EF to I-1, 2-2, 3-3, etc., are transferred to the same numbers from the line CD which gives an oval shape as shown and is the true form of the bottom of the trunk. The process of setting and flanging the cone-shaped trunk is similar to the other, only care must be taken in rolling the plate to the lines given or the ends will not come together right. The trunk should be put in the rolls with the line AC parallel to the rolls. With the exception of the plates laid out with molds the work is done sim- ilar to the Scotch methods. and_ is done. as cheaply as it, is done in Scot-, land. = SHIP BUILDING AT BALTI- Seas MORE. : ; Baltimore, Md., Dec. to--The E.
