3DSP Samples

Here are some of the samples I have made for my 3DSP project. All samples have been made using the power hammer with minimal hand work with the exception of the tooling.

Leaf hammer forged from 25 mm square EN9 high carbon steel. The hole was punched by hand and the cheeks were drawn out on the fullering dies on the power hammer. All necking and forging of the faces was done using a broad fuller and striker.

Rodded chisel punch forged from EN9 high carbon. The hole was punched and drifted by hand, and everything else was done using the power hammer.

Texture and spread sample forged from 5 diameter pipe section. Half of the pipe was compressed and forged under the fullering dies, while the other half was untouched.

Here is a close up shot of a sample that I ended up incorporating into my gate for design development. It is a 40 x 12 mm flat that has been heavily fullered on edge so that it upsets the edge of the material while necking it in. It has to be done slowly and very hot with the finishing work done very cold. This creates a natural valley in the center of the piece that I really like. The best part about it is that the most interesting bit of the sample has been created without any direct hammer contact.

Here is part of my gate for design development that uses side set tooling to set down material under the power hammer.

A close up of the set down. Please view the video for a full demonstration of how it was done.

Side set tool forged from spring steel. This is the tool I used to do the set downs in the above sample. I took this design from the videos by Toby Hinkman. I also looked at the Lillico book for inspiration.

Cut off tool forged from spring steel.

This sample plays with the possibilities of set downs and material isolation.

Punches made from EN9 high carbon tool steel. All three were forged smith and striker using mostly the flatter.

This is a sample using an interesting spring swage that I found on the rack. It has a single round fuller on top and two round fullers on bottom.

The opposite side of the same sample.

An interesting finial sample made using the side set tool to isolate the end of the bar on two sides. The end was then squashed on the blacker mechanical hammer.
