Shipbuilding in iron and steel / a practical treatise . . e forging has been completedit is taken to the machine, and the heel, sides, lugs, &c., are course was followed in the Northumberland; and when thewelding of the body post had been completed, in the manner justdescribed, the rudder post was hoisted into place and secured. Theweight of the two posts and their connecting pieces, exceeded 40tons. It will be seen that in this ship the connecting piece, at thecounter, was a separate forging, and was connected to the pro-jecting pieces forged on the posts by two hooked scarphs, whosepositions are shown in the elevation in Fig. 62. The slabs used inforging the stern posts of this vessel were made of the best selectedscrap-iron, such as the shearings of rolled plates, and other new,clean scrap kept for the purpose of forging important work. The arrangement proposed for the King William, Prussianiron-clad frigate, previous to her being supplied with a balancedrudder, is illustrated by the elevation and view of the after side of. Fig. 67. the rudder post in Fig. 67. The connections of the keels, &c.,with the sole-piece are of an identical character with those of theNorthumberland, and it is, consequently, unnecessary to showthe lower part of the stern frame, the peculiarity of the mode ofsecuring a firm connection between the head of the post and the F 66 Stern Posts. Chap. iv. stern beine: that which constitutes its interest. In the commonarrangement an attempt is made to increase the connection of theheavy stern posts with the body of the ship by bringing the headsof the posts up to a deck and securing them there. In the casebefore us we intended to combine the upper part of the rudderpost with the frame of the vessel by forging horns on it. Thesehorns were formed as shown in the view of the aft side, and ex-tended 5 feet up the side, being tapered, in thickness, from G inchesat the middle line to 1^ inch at their extremities. They werebolted to the outsi
