Sweet! Thanks Ford. Do you ever use a different chisel angle than the one shown sideways?

[Dick Bonham]

Hi Ford,
Thank you Sensi for doing this. We can never learn too much or have too much information about our passions. I can't wait to see your website. When do you think your book will be published? You should also consider doing a DVD so we could watch you work. There are no books out there that show these techniques. Bits and pieces but nothing complete. You are charting new territory.
Thanks again
Dick

This is amazing - I see so much here I want to learn. What guage is the foil you are using? I have been making my punches for repousse work from square drill rod - would this be suitable for making these chisels? What is the type of steel your disk is made of? I hope you are going to publish soon, though I realize that I am looking into a whole new field of exploration that will take me years to absorb, so I personally am in no true hurry. Thank you so much Ford for your generosity!

Hi Ford,
I have been wanting to try this thank you for putting the information out. I have notes from my visit, but the chisel side shot is very helpful. I would also like a measurement on the foil thickness. Is fine silver the best practice material?
I was inspecting a gold and iron Kabutogane that had the rim work done in Nunome. The gold appeared to have 100 percent coverage on the rims at first glance. Looking at it with a loop however revealed many tiny iron dots showing through the gold. Would this be the result of wear or are they meant pierce the foil in a subtle way? In this particular case it did not appear to be an intentional shading effect.

Aloha Ford,

Let me add my thanks to the chorus. Thanks! The only other place I've ever seen this technique is Von Neumann's book and I nearly go blind squinting at the fuzzy images.

Questions that come to mind:
I am seeing a copperish blush in the image of the grounding process. Is that transfer?
Does the foil tear so much as actually cut away at the edge of the cross hatch?
I noticed a little "tooth" on your cutting tool.. to help anchor the foil?

mahalo

Aloha Ford,

Thanks for answering my picky questions. (I need a better monitor.) As the tutorial develops, myself and others who want to try this technique will probably scramble around to find the pieces and parts to give it a try. Maybe part of tutorials can be sourcing or a link to materials? Don't know.
Von Neumann's book had a similiar effect on me (I have my original copy). Gene P. tells me this incredible story that some of the images are of masters' works kept in a vault under the university. What I would give....

(Is that a custom piece of bamboo chopstick I see?)

Wow - that's so very cool! Thanks Ford.

I think the info presented sofar is great. larger photos of the closeup views help to actually see how the process is completed. i think drill rod is fine for the chisels,there are several dealers who have W1 or W2 tool steel in various sizes at fair prices.here is a link that has been posted here before,but the photos are small.

these 2 images will hopefully give an indication of the scale of the tools, etc. The close up of the left hand grip shows the chisel not perfectly vertical, this is actually incorrect, it ought to be at 90 degrees to the surface being cut. I'd adjusted my position to allow my wife to get a decent shot. , and not re-adjusted the pitch bowl. The other view shows the grip on the right hand holding the hammer, it's quite a delicate grip. The hammer is very light and the shaft is quite flexible bamboo. The action is a rapid, almost bouncing, tapping. The springiness of the bamboo and the chisel rebounding off the metal allows you to create a sort of chattering movement forward, with a little sensitive guidance, of course. I hope that helps describe the cutting action. Film footage next, I suppose.

cheers, Ford

Well I tried it out today and have the process working. It of course needs refinement. I made foil of the recommended thickness. That is as thin as I can go in the rolling mill. I tried the cloth weave and that works well, but the cuts are too irregular for a super clean look. I tried cutting in four different directions and that worked well yielding a smooth unbreached overlay, but my cuts were more shallow and numerous and the cloth pattern is lost. I need practice, but I am excited at the results I have from a few hours of playing. I do have the advantage of having seen Ford's tools for this in person I did not absorb it all from this thread. I had a little spare time today and this thread inspired me to dig out my notes and give it a try. What happens when you use thicker foil? Never mind Ill find out...
Thanks Ford,
Patrick

Thanks again Ford.

Hi Patrick,

that pretty quick off the mark, I'll have to watch you! nice to hear that you were able to get the basic procedure to produce results.

I've just re-read the thread and realised that I omitted to describe one very important detail; so here it is, the secret teaching ,and I know how you all love "secret teachings"

This concerns the little copper tipped tools I used to secure the foil initially. If you look at the image showing two of them you may notice that the one on the left appears smoother, while the other one has a frosted face.

This is crucial, the small saw sharpening file in the image of the tools at the beginning, is the key. The pushers need a finely textured face. This is applied by lightly tapping the copper tools mushroomed face with the file. This results in a grainy/ texture sort of like a 400 grit emery paper. The pushers are used in a firm but very controlled, and small, rocking motion. Not back and forth, more a single roll, then lift and another press and slight roll. The texture is very quickly worn down and must be re-applied. I generally have about a dozen little pushers to hand and simply retexture them all at once. You may begin to feel when the foil is really being attached and worked in place. Once the surface has been completely worked you can go over again with a bamboo or horn punch. After that a series of passes in different directions with a burnishing tool should ensure that the foil is going no-where.

The use of the pushing tool is only really necessary when applying foil or wire to very finely cut grounds and when working on hard, non-ferrous alloys, like shibuichi. If you prepare a rougher ground you may find that bamboo punches are sufficient to secure the foil, especially if the ground is mild steel or iron. In this case cut the last few mm of the bamboo punch off whenever you notice it's getting compacted and hard. That's why I use take-away chopsticks! As with the copper pushers, it's all about getting the foil into the gaps in the cut ground, the softness of the bamboo allows the foil to fit around the cut texture before it is pounded too smooth. It is a similar thing that happens with the copper pushers. The copper pushers are called oshitsuke in Japanese btw.

this little thread has made me realise just how much detail needs to be described to accurately convey a technique like this , I hope this little taster is sufficient to at least help some of you make a start.

happy tapping , Ford

You showed me how to texture the tool, but only now do I understand what for. The work I did yesterday reinforces it for me. If I have the right idea, initially you only push the metal into the cuts, while avoiding flattening the metal that is over the ridges/spikes formed between cuts. A softer pusher can get the silver down to the bottom of a deeper cut without smashing (thinning) the silver over the ridges excessively. I am finding the balance in cut depth as well. Too deep and you can not burnish smooth. Too shallow and it does not stick very well.
I find it interesting how thick the overlay can look when its done. After thinking about it the texture formed from the cuts is higher than the surface fo the plate and silver is on top of that.
