SHIP-BUILDING. 



tlnvartfhip view of the aft-fide of the fafhion-piece leaves 

 the rabbet of the ftern-poft, in order to be conformable to 

 the vving-tranfom at the fide, is eafily perceived by the 

 Ihaded lines. 



Till this thwartfhip \ievf of the aft-fide of the fafhion- 

 piece, t, be (hewn in the flieer-plan, _/7f. lo, the ribband- 

 lines cannot be truly ended, although the operation is the 

 fame as before defcribed. 



Though the aft-fide of the fartiion-piece i, in the ftieer- 

 Y>hn, Jig. 10, leaves the rabbet of the Ifern-poft at the head 

 conformable to the end of the vving-tranfom, yet a fquare 

 line at the feating muil be drawn as before, to lay-off the 

 tuck on the flat ; therefore, take the nearelt diftances from 

 the fquare line a, in the fheer-plan, _;?§^. lo, to where each 

 horizontal line crofles the aft-fide of the fafhion-piece i, and 

 fet them up from the horizontal line S, in the body-plan, 

 ^g. II, ftriking horizontal lines, as dillinguifhcd by a fine 

 tick. 



Then take the half-breadth of the wing-tranfom, in the 

 body-plan. Jig. 1 1 , fquare from the middle line, and fet it 

 off from the middle line, on the line A A. Next, fix one 

 leg of the compaflbs at the end of the wing-tranfom, in the 

 Iheer-plan, Jig. lo, and take the nearell diltance to the aft- 

 part of the rabbet of the itcrn-poft a, which is fquare from 

 the rabbet, as the hne e ; and fet it off fquare from the line 

 A A, at each end of the tranfom bi; and fweep the arc 

 cc, which gives the round-aft of the tuck at any height, 

 fquare from the rabbet of the ftern-poft. Square down the 

 fine-ticked fines, or horizontal lines, 2, 3, 4, 5, 6, and 7, 

 on the rake where they interfeft the horizontal view, a, of 

 the fafhion-piece in the body -plan, ^^. 11, to the round-aft 

 line, on a fquare under the body-plan. Then take their 

 diilances from the middle line, on the curve c c, or round- 

 aft, on a fquare, and fet them off from the middle line of the 

 body-plan, Jig. 1 J, on their correfponding horizontal fines ; 

 then pin a batten to thefe ipots, and to where the feating 

 interfefts the poft, and it will give the form of the aft-fide 

 of the fafhion-piece J, to which the mould is to be made, 

 that will agree with the other timbers, when in their 

 places. 



To be correft with the length of the wing-tranfom on the 

 flat, take the half-breadth from the body-plan, ^^. 11, on 

 the round for the upper fide of the tranfom ; then continue 

 the end of the tranfom in the half-breadth plan, ^^. 12, 

 fquare out from the middle line, as at f ; on which (fquare 

 from the middle line) fet off the half-breadth taken on the 

 round from the body-plan, ^^. 11, and from that fpot fweep 

 an arc to break into the middle of the tranfom, at the 

 middle line, as reprefented by the dotted line a ; then from 

 the before mentioned fpot, or end of the wing-tranfom at i, 

 take the half-breadth round the dotted curve to the middle 

 line, and fet it off from the middle line in the boriy-plan, 

 Jig. II, round the curve, for the upper fide of the tranfom. 

 This will give the exadl length of the tranfom on the 

 round-aft of the tuck. 



Previous to the laying-ofF of the fore-fide of the fafhion- 

 piece,- it will be proper to underftand in what manner the 

 fafhion-piece is to be moulded and trimmed, particularly on 

 the fore and after-fides. 



Make a mould to the moulding, or outer edge of the 

 fafhion-piece laid oft on the flat, as the fine ticked line d in 

 the body-plan, ^o-. 11. The upper end may be made as 

 high as the height of breadth, or horizontal line 7, and the 

 lower end may reach to the feating on the poll. Let the 

 upper end of the mould be cut off well with the direftion 

 of the horizontal lioe 7, and let the heel be exactly perpen- 



dicular at the fide of the inner poll. Make another mouM 

 to the round-aft, on a fquare cc, as fliewn under the bodyJ 

 plan. Jig. 1 1, and of a parallel breadth, like part of a beamJ 

 mould. Make it as broad as the fafhion-pieces are mtendecF 

 to be fided, and let the midfhip-end be well with the fide of 

 the inner pofl, and cut off parallel to the middle line. Let 

 the fide-end correfpond well with the moulding edge of the 

 fafhion-piece, and cut off agreeable to the round of the fide 

 when the mould lies in its proper place, underneath the 

 body-plan, 7?f. 11. Let the fafhion-piece be fided fuf- 

 ficiently for the wing-tranfom to dovetail into the aft-fide 

 of it, and let the fore-fide of the fafhion-piece, that runs 

 above the wing-tranfom, be of fufficient length to receive 

 the bolts of the fide ftern-timber, and long enough at the 

 heel to meet at the middle line. 



When the fafhion-piece is roughly fided on the aft-fide, lo 

 as to lay the mould on the aft-fide, to mark tlie upper and 

 lower end nearly, then cut off the head by the mould for 

 the thwartfhip-way, and tlie fore and aft-way, fquare. Then 

 fallen the round-aft mould, that is made to the fiding, on 

 the head of the fafhion-piece, by which may be trimmed 

 the fore and after-fides of the fafhion-piece out of winding, 

 by lines parallel to the middle line. Thus will you have 

 the belt opportunity of feeing how to convert the piece, by 

 feeing both fides at once. Then will the fafhion-piece 

 be of a parallel thicknefs from one end to the other, 

 by all fines that are parallel, whether perpendicular or 

 horizontal. 



To Lay-off the Foreftdi of the f'aJhion-Piece. 



Having the fiding of the fafhion-piece on a fquare, fet it 

 off in the fheer-plan, ^. i, fquare from the rabbet of the 

 ttern-poft a ; then with compaffes take the fiding of the 

 fafhion-piece in the diretlion of the horizontal lines, and 

 fet it off fquare from all the aft-fides of the horizontal lines, 

 prolonged in the half-breadth plan,_^^. 12, on each horizon- 

 tal fine, and fquare them up on their correfponding lines in 

 the fheer-plan,^^. 10. Then pin a batten to thofe fpots, 

 and the fore-fide of the fafhion-piece c will be reprefented. 

 Take the heights above and below the fquared line d, in the 

 fheer-plan,_^». 10, to the interfeftion of each horizontalhne 

 with the fore-fide of the fafhion-piece c, in the fame manner 

 as the aft-fide was done ; and fet off above and below the 

 ticked line S, in the body-plan, _^^. 1 1, and flrike horizontal 

 lines, as there diftinguiflied by long-tick. Then take the 

 half-breadths in the half-breadth plan,_^_f . 1 2, to the fore-fide 

 of the fafhion-piece on the horizontal lines, fquare from the 

 middle line ; and fet them off fquare from the middle line 

 on to the line for the round-aft, on a fquare c c, under the 

 body -plan, ^^. 1 1. Then take them off again on the round- 

 aft line, and fet them off from the middle line, on their 

 correfponding horizontal lines in the body-plan, _/!^. 11. 

 Then pin a batten to thofe fpots, and the form of the fore- 

 fide of the fafhion-piece e will be agreeable to the fiding 

 propofed. 



The aft-fide of the fafhion-piece not being flraight, will 

 render it more troublefome than ufefu!, to run lines in order 

 to trim the outfide of the fafhion-piece by bevellings; there- 

 fore it would be better to make a mould to the fore-fide e, 

 and trim a fpot to fay to the fide of the inner poll or dead- 

 wood ; and fet off a bevelling for the outfide at the main- 

 breadth, as at ^, Jig. 12. 



Mark the fine at the feating S, in the body-plan, fig. i r, 

 on the mould for the aft-fide, and on the mould for the fore- 

 fide ; and when the aft-fide is moulded, and the fide trimmed 

 to fay to the inner poll, mark the fpot i fquare from the 



aft-fide
