I have a koshirae project going on, where I plan to build a low-cost koshirae for a blade with a hagiri, so that I can have a nice display piece with little value that I can use in lectures, and let also less experienced people handle it. Well, I realised that I did not have a habaki for the blade - probably lost it somewhere. Anyway, the original habaki was a battered plain copper one, so no big loss.
Being on holiday, I decided to give it a try and make one myself, although I had serious doubts about succeeding. So I bought some 2 mm thick silver plate, special brazing materials, a torch, watched a couple of youtube videos and started. I want to emphasize that I would not do this on a valuable blade; hammering a silver plate around the nakago is a little scary business. Why I decided to use 925 silver instead of copper? Well, it is more ductile, looks better, and the material cost me only 45 Euros. The first brazing trial was a total failure, but then I tried Bergeon 5337 brazing rods with flux core and then things started to go smoothly.
I finished the project today, pics attached. Well, it is not perfect but does the job. Actually, I was rather happy with the result, since this project was more a learning experience than anything else.
