Hello folks,


As most of you noticed, I have been pretty quit lately.. I have some personal reasons - mostly financial if you think about it - but it comes down that I moved out and gotta take care of my own now. I suppose most of you guys remember the first steps away from your parents :D.

Anyway.. I have a cool story and several questions arising from them.

A very close friend asked to make a knife for her father. I had a tough time saying no, but then I accepted as it was not going to be anything fancy. She is great designer and made a really pretty design, which fitted perfectly in a 30 mm wide bar, it has to have scales and is about 9 inch long. I had a bar of D-2 of that excact size there... So I started filing as it was annealed.

It filed flawlessly, but then I needed to make the cutout in the ricasso... and my file slipped ( and I bumped my hand painfully :eek: ).. I tried to figure out why but i find nothing.. I suppoes there is a hard surface spot so i file a bit harder to get through it.. .... ping... entire bar break in half :eek: YIKES.
I started to freak almost.

Anyway, out of shear frustration I started agian on a bar of 1084 which I actually keep for forgeweldeing as it's pretty thin stuff (1/10 th inch).

Now my questions :

1. What happened to the D2 bar? I mean I could file the rest with the excact same file easy. I'm still a little puzzeled.

2. How do you HT 1084 excactly, because I need this to be a excellent edgeholder - gonna be a farm knife ... kinda ? I can do edge quenches but this is thin stuff so I'm kinda worried. How thick do I leave the edge? Can I do vacuum (molten Salt) quenches in Goddards goop ? How much to temper and how many times? And how good of a cutter will it become?

3. If someone has a bar of D2 of 1 1/4 inch wide by 8 inch too much and is interested in amaterials trade, lemme know too :D

Thanks for the answers in advance...

Greetz and take care, Bart,
 
Bart I will take a break from the Sole Authorship debate thread and attempt to answer your HT question.

1084 Heat to nonmagnetic and quickly quench in warm oil about 135deg. Temper 2 times at 375-400 for one hour each. Pretty easy stuff.

I have no idea why the d2 snapped like that. Maybe it was stressed and hard in spots? Did anybody abuse it with a torch? I dunno.
 
Thanks bruce

That was just the info I was looking for... tempering times and so on.

Why the D2 snapped I dunno... I bought it from the manufacterer as annealled D2 and I use it for stoch removal only, so I never even get it cloe to a flame. Might be a bit frozen up last winter since my shop has no heating :D

Ah well.. these things happen :D

Greetz and take care, Bart.
