These fullers, which are used to forge simultaneously an equal shoulder on stock, are only remarkable in that I have used wood for the shanks instead of steel.
The hardy hole is not square to the anvil’s face, so I would have had to draw down,taper and bend 30mm square bar, before cutting and welding, and then, probably, take another heat to adjust. This would consume quite a lot of energy. Besides, I don’t have 30mm square, so I should have to use round, which would be more work.
You see in the picture, on the left,that I have flattened some tube and selected two surplus pieces of medium carbon steel to insert in the ends -0ne a surplus punch- prior to a tack weld.
Then I shall take a low heat, and bend it around a tube, trying to make sure that the holes drilled are aligned, so that afterwards, I can screw into the shank.
These are, I realize, very crude tools, but I hope they are of interest to some.
This is just to show what it looks like in the anvil: the shed is very dark, sorry. This is the first I did, flattening a piece of solid bar, which is a stiffer spring.
None of them is tempered: they won’t have a lot of use.
