Today I 3D scanned a stone aged axe my Grandad found many years ago in England. I have always loved the shape and form of the tool and how it fits perfectly into the hand.
I wanted to use this form to create tools to make forms for pieces for the house.
I scanned the axe at the university and then used the files to create both silversmithing stakes and hammers.
For the stakes I kept the original size of the axe and added a section that would allow it to be gripped in a vice. For the hammers I scaled down the model to 85mm and cut out a hole for the handle.
I am planning on 3D printing the models and casting them possibly in bronze.
I had a very exciting few days in the workshop testing my hammer. One thing that I didn’t realised was that the handle was too big to grip properly. So I went to the wood workshop and got it sanded down on the belt sander.
Sandra Wilson then gave me a quick afternoon master class in Dutch Raising. Dutch raising differs from the more well known technique of angle raising in that you hammer from the inside of your piece out. This creates a wave in the metal as you push the metal round. After each round you calque the edges and the re-anneal.
The second day I continued the piece and go to the planishing stage. I used my 3D printed steel planishing hammer. I also used the wrong steak at one point which put dints into the bottom of the bowl. I actually quite liked this so I ran with it.
I wanted to finish the bowl well and in an interesting way. I had some copper foil which I wanted to use for the inside of the bowl. I tried a sample of copper on copper kuem-boo but this didn’t work because copper doesn’t fuse. the samples just flaked off and they also changed to a more pastel colour.
I decided then to leaf the inside using adhesive. The outside of the bowl I finished with platinol and I burnished the top edge to a shine.
Last week my handle for the raising hammer I made in Hungary was CNC milled in birch wood. It had taken quite a lot of time because previously it had been milled in oak. When I spoke to the wood technician he said that the grain of the wood was at an angle and that this would split when used. It brought up a very interesting conversation about the need for craftsmen and traditional crafts skills in the field of modern technologies. Not all items made using modern technologies will work or be better than something handcrafted but that it is the knowledge of both that are needed to apply ideas.
I glued the handle together in the workshop with wood glue and clamped together for around an hour.
When the handle was taken off the milling machine it had supports on the sides, I cut these off with a saw. I then filed and sanded the handle and fixed the hammer head in using epoxy resin.
I am now using Danish oil on the handle every day for the next week. I still have to drill a hole through both the handle and the head to fix a rod through.
