Bifurcated serrated Tulwar repair

Hi All
Thanks for comments.

I used a Dillon MK II Oxy acetylene blow torch which has a lot of different nozzle sizes so you can really small Jet, nearly as small as a pencil nib for the jet of flame, it is a v v neat tool.

I want to get a tig welder but have not been able to investigate what is out there as a hobby usage one

For the filler rod I used 1mm Tig welding wire so I could keep the heat down low.

The donor blade was part of an old sword blade i got in mixed auction lot, had just the correct amount of pitting to suit the original blade.

Once i ground the weld and put in the serrations with a dremel tool and a file I cleaned the weld and browned the fresh steel in a hot mix of copper sulphate and nitric acid.

I then buried the blade with this mix on it for around a week in a shallow middy patch in the garden and heaped salt onto the mud and let it rust a bit more

Once finished oxidising I washed with boiling water after neutralisation with bread soda.

Thanks for interest, what age do you think the sword might be?

Ken,

Very nice job. I suspect when we are all long gone and someone comes across your sword they will speculate on when the repair was done. You've matched the materials and pieces so well that I expect our future fellow collectors will think it must have been done back in the day when so many skilled sword makers and repairers were still around: "Man, look at that repair--almost impossible to see--must have been done by some old craftsman--nobody today could do that ..."
