WHOLE. MOULDIN<5. 



thicknefs of the board ufed for the bottom, the back of 

 which arch will give the ending of the fore part of the 

 main-half-breadth line. Then fet off the half-breadth to the 

 outfide of the timber at the midftiip-bend, and draw C D 

 parallel to A B. Determine the breadth of the tranfom at 

 the top of the fide, and fet off the half -breadth on the line 

 for the aft-fide of the tranfom. 



Thus we have three fpots, one at the aft-fide of the 

 tranfom, one at the midfhip-bend, and one at the item, 

 through which draw an unlimited curve; obferving to 

 make it faint about half the length of the boat in mid- 

 fhips, and to form the bow by part of a circle. 



To form the Midjhip-bend. — Draw the horizontal line A B 

 {fis- 3-)' ^"'^ ereft a perpendicular in the middle; then 

 take the half-breadth of the boat at the midfhip-bend, in 

 jig. 2, and fet it off on each fide the middle-hne, and 

 ereft the perpendicular C D. Take the height from the 

 line A B, _/^. i. (which is the upper edge of the rabbet of 

 the keel) to the rifing-Une, and to the height- of-breadth line 

 at the midfhip-bend ; and fet off above the line A B on the 

 perpendicular C D, fig. 2, and draw the lines marked 

 M B, and " Rifing." 



The diftance from the rifing-line to the height-of-breadth 

 line, is the radius of the circle intended for the midfhip- 

 bend ; which diflance, fet off from the point where the 

 half-breadth Une interfefts the fide perpendicular, c, on 

 the height-of-breadth line, will give the centre for the 

 fweep of the midfhip-bend ; then fweep an arch from 

 the interfeftion of the perpendicular c to the interfeftion of 

 the rifing-hne. 



From the middle-line fet off the half-breadth of the keel 

 on the line A B, and draw a ftraight line from the fide 

 of the keel to the back of the arch of the midfhip-bend : 

 let the top of the fide above the height-of-breadth line be 

 perpendicular, complete the other fide of the middle-line the 

 fame from perpendicular D. 



To form the fquare Timbers of the Fore-Body. — Take the 

 diftance from the line A B, fig. i. to the rifing-line at timber 

 A B, &c. as far forward as timber I, and fet them off, 

 and draw lines parallel to the line A B, fig. 3, from the 

 middle-line towards the line c. 



Then take the diflance from the line A B, fig. i, to 

 the height-of-breadth line at each feparate timber, and draw 

 them as before in_^^. 3. parallel to A B. 



Then take the half-breadth of each timber, A B, &c. 

 in_^^. 2, and apply each feparate diflance from the middle- 

 line in fig^ 3, on the lines of their correfponding names for 

 the height-of-breadth, and there make a fpot. 



Make a mould agreeable to the fhape of the midfhip- 

 bend, the lower part to agree with the rifing-line of the 

 midfhip-bend, and extend as far beyond the middle-hne as is 

 neceffary. 



Crofs the height-of-breadth on the mould, and the 

 middle-line, when it lies well with the midfhip-bend. 



Take the diftance from the line C D, fig. 2. to the main- 

 breadth line at timber A B, &c. and fet them off from the 

 middle-line on the lower fide of the mould, towards perpen- 

 dicular c, which fhews the narrowing of each timber more 

 than the midfhip-bend 



From the height-of-breadth line in fig. I. take the dif- 

 tance to the top of the fheer-ftrake at each of the above 

 timbers, and fet them off above the main-breadth, on the 

 mould, which gives the heads of all the timbers in the fore- 

 body. 



The lower edge of the mould is fuppofed to be the height 

 of the rifing-line from the timbers. 



Then apply the lower edge of the mould on each rifing- 



line, _^j-. 3, and move it till each letter on the lower edge 

 of the mould agrees with the middle-line, and the main- 

 breadth on the mould agrees with its correfponding height- 

 of-breadth line. Then draw the form of the mould from 

 the head of the timber to the middle-hne, as ticked iafig. 3, 

 and draw a ftraight line from the fide of the keel, at tlie 

 upper edge of the rabbet, to touch the outfide of the curve 

 formed by the mould, except where the rabbet of the keel 

 and ilem rifes, as at F, G, H, I. 



Set off the half-thicknefs of the keel from the middle- 

 line, fig. 3, and take the height from the line A B, fig. i. 

 to the lower edge of the rabbet at each timber, and fet it 

 from the line A B, fig. 3, on the line for the half-thicknefs 

 of the keel or ftem ; then with compaffes fet to the thicknefs 

 of the bottom plank, fweep an arch ; from the upper fide 

 of which draw a ftraight line to the back of each curve of 

 the mould, which will finifh completely the heels of the 

 timbers. 



The fame method muft be obferved in the after-body 

 towards perpendicular D, fig. 3, applying the midfhip- 

 bend mould in the fame manner as direfted in the fore-body, 

 making ufe of the mould as far aft as timber 12. 



The after-fquare timber is 9 ; therefore, to 9 may be 

 finifhed the heels of the timbers, by drawing a ftraight fine 

 from the back of the whole-moulding curve to the back of 

 the fweep at the rabbet of the keel. 



In whole-moulding, but few moulds are neceffary to be 

 made to mould all the timbers. Thus the floor-mould is 

 to be made to the midfhip-bend in fig. 3, a little above 

 the diagonal line, a i or ac, which is to be the heads of the 

 floors, and let the lower part of the mould correfpond 

 well with the rifing of the midfhip-bend, as is fhewa in 



Js- 4- 



When the mould lies well, as in fig. 3, mark the middle- 

 line on the lower edge of the mould, and the head of the 

 floor on the outer edge. Make the infide of the mould to 

 its proper fcantling, and let the upper edge correfpond well 

 with the cutting-down of the infide of the midfhip-floors ; 

 which cutting-down is fo marked in fig. 1. 



Then in fig. 2. take the diftance of each timber from 

 the line C D to the main-half-breadth line, and fet them off 

 on the lower edge of the mould, from the middle-line of 

 the midfhip-bend towards the outer end of the mould, which 

 is the middle-hne for each floor. 



Now fix the lower edge of the mould in fig. 3. on each 

 rifing-height, in the fame manner as the timbers were 

 got in by whole-moulding ; and when each mark on the 

 mould is well with the middle-line, and on its proper rifing, 

 defcribe on the outer edge of the mould the heads of the 

 floors, or the diagonal line a b, or a c. 



Or, as in fig. 4, fquare the middle-hnes of each timber, 

 and then take th? half-breadths of each floor from fig. 3. 

 and fet them off fquare from each middle-hne infig. 4, to 

 interfeft the edge of the mould. 



The lower FuUoct-Mould,fig. 5, is made to the rifing-height 

 of the midfhip-bend, and from thence to the top of the (heer ; 

 but need not be made fo long at the heel as the floor-mould. 

 The infide is made to the fcantling, and the croffing of the 

 middle-hne and the floor-head, on the lower futtock-mould, 

 is done in the fame manner as on the floor-mould ; or the 

 beft way is to lay the floor-mould on the lower futtock- 

 mould, and crofs it by the floor-mould. When the lower 

 futtock-mould is laid in its place to the midfhip-bend in 

 fig. 3, then mark the main-breadth on the mould, which is the 

 main-breadth for all the timbers. Then take the diftance 

 in^^. I. from the main-breadth Une to the top of the fheer 

 at each timber, and fet it off on the mould, from the main- 

 breadth
