Making frames

A very instructive picture. There's really not any need for words beyond the terminology, which I only have in Norwegian. The machine in use is called a "puffemaskin" in Norwegian, and if that is derived directly from English, the name would be "pushing-machine".

I was talking about the machine in the upper left with which the frame is hammered into shape.

From "Wivenhoe remembered": ...the frame bender would make a template of each frame, with a piece of flat bar, about two and a half by half inch, and they would be bent flatways, and that would be tried on the screed board, and you’d have to get that perfectly right with the screed board, for each frame, then it was taken to a big cast iron slab, which had a series of holes all over it, and that would be what we called ‘dogged down’ with dogs – they were angled pieces, with a square, so they couldn’t turn, square hole, square dog – and the other end was turned down so that when you knocked that in and tapped that, the other end would very firmly hold the flat bar. And it did. And, consequently, you’d have these all the way round the flat bar, on the inside, and you had made allowance for whatever width of frame that was standing flange, and you’d draw that bar out of the furnace, in its red-hot condition, and that would be donkeyed round with a squeegee, in the holes, like that, to repeat the bar shape. Try it on the screed board afterwards, when it got cold. Any adjustments would be done with a hammer, it wasn’t totally cold. And then, of course, they all had to be angled, because of the shape of the ship, so every frame had a changing angle all the way round, and that all had to be done.

The frame profile guage is laid next to the dog's and chocked from behind. The new frame is then "bent" against it. The bending machine is hydraulic.
