Matashichi Hayashi Utsushi

For work in progess and finished pieces

Matashichi Hayashi Utsushi

Postby cam_hardiman » Fri Jun 16, 2017 6:48 am

Progress on my Matashichi Hayashi Utsushi, Plum Blossom and Moon from tutorial no 2.

I printed to image out in scale then placed it onto the a pice of 5 mm steel plate. A few drops of thick viscosity CA glue, that spread throughout the print like it was tissue paper, and the images was fixed onto the steel. The print layer with the CA glue is pretty hard and survived some rough treatment.

I ran out of Glardon Vallorbe 2/0 blades halfway through cutting the tsuba. So I switched to Super Pike 2/0 that I had as a back up. The Super Pikes didn't like cutting bends and corners as much as the Vallorbe blades did; they were much better performers.

After the cutting was completed, the image was removed with acetone.

I started the filing. Its going to take quite a while to complete. In case you are wondering about the patchy colour of the steel? It was cold rolled plate so the skin was hard. So it spent the night in the fire. Now it's workable. The night in the fire would have burnt the print layer off as well.

A good start, Cam.

One quick tip, before filing and after annealing you might want to pickle the steel to remove any scale. Fire scale is harder than the steel itself and will dull your files more quickly.

Jewellers safety pickle (used only for ferrous, don't put copper in it or you'll plate the steel) or diluteted HCl, muriatic or swimming pool acid does a quick job. Just don't leave the piece in and forget about it :-p Rinse with a little bicarb to neutralise when clean.

Great tip Ford. I do that now. Thank you.

I'm already planning my next Tsuba...I think I'm addicted.

Some more filing, two days worth in fact. I'll be putting this aside soon until I get myself a pitch bowl and some tagane. Still of work to do on this Tsuba.

Next Tsuba is on the drawing board.

Looking good Cam. Since I'm following behind you with this tutorial, I share your pain. I'll post pics eventually.

Thanks for posting.

Great Steve,

Post it here if you like. I have a little more filing to do. Then I plan to patinate and add copper sekigane. I don't have carving tools yet (they are expensive to bring in from a Japan), but do plan to purchase soon.

I'll return to the Tsuba once I have the tools and some basic carving skills to finish off the detail in the flowers and buds. I'll do as much detail as I can with files in the meantime.

Steve,

The Tsuba look good. Now the fun starts with the files. I found a Vallorbe half round 2 cut escarpment file was my main go to file, after working the outer rim with a 6 inch half round.

I also tried an assortment of 5/32 x 5/32 Gesswein diemaker stones. I used them after filing to work the tips into some hard to get areas. The 400 grit was similar to the escarpment file by way of cut, material removal and finish. Anything under 400 grit was going backwards.

The 600 grit stone did a reasonable job of removing the marks left by filing and the 400 grit stone, leaving a half descent finish. Not quite as good a finish as other more traditional options—Water of Ayr. It would have been good to have a 500 grit in between. Which I'll get 500 grit for next time, along with a higher grit, perhaps around 700-800 in a finishing stone, rather than diemakers. At only a few dollars each I can't complain.

Cam, I wouldn't bother with chisel blanks from Jpana, I gave up on them years ago.

Either contact Dietrich Podmajersky at Podforge for CNC milled blanks of suitable size for adult male hands ;-)
or contact Micheal Coffey for hand forged versions of the same. Both Mike and Dietrich are members of the forum so easily contacted.

Thanks for the tip Ford, looks like I'll be in the game a little quicker than I thought.

An update.

Getting close to the final finish on the Tsuba before patina and sekigane. Also slowly fixing up some of the edges and adding what detail I can achieve with files alone..

I've been searching through the forum, and thanks to Ford's post some time back, I am going to order the chisels listed along with their widths, just to get me started.

3 shishiai-bori chisels ( 2.5mm, 3.5mm and 5mm)
2 kata-kiri chisels. (3.5mm and 5mm)
3 maru-bori chisels ( 2mm, 3.5mm and 5mm)
2 kebori chisels (about 1.5mm)

I am unsure of the thickness of each of these chisel. I assume that the kebori chisels are square an would be 1.5 - 2.0mm? All the other chisel thick enough to create the flat chiselled cutting edge?

I'll also get two scrapers.

Thanks in advance.

Cam

Mr. Cam,
Most of the guys here would be making their own chisels so it's a bit of a hard one to answer. Most blanks will come as just that, blanks, ready to be shaped and hardened. Are the chisels you are buying finished items ?
