  1. 6db.jpgAnother possibility: your files are case-hardened, and your first Rockwell test hit the outer skin, the subsequent tests hit the soft core.  This requires Nickolson to at some point to have made case-hardened files, which goes against everything I have heard about Nickolson files....

  2. This one has me scratching my head.  Steel: old Nickolson, as quenched hardness: 68 HRC.  This right here let's us know your blades most certainly fully hardened, and decarb isn't an issue.

    1095 that has been hardened to industrial standards, tempered to 450° should be 61-62 HRC.  I'm not sure how hot you would need to temper 1095 at to reduce the hardness to 43 HRC, my chart cuts off at 650° Fahrenheit which results in 53-54 HRC.... Did you temper them at 450° Celsius by any chance, because that would probably make sense.

    A couple possibilities.  

    Your kitchen oven is off by 250°+, or it's metric...

    Your as-quenched Rockwell test was off....

    I'm at a loss, really.

    Nice. With that much time (6hrs) tempering to straighten, is there a risk of taking too much hardness out? 

    Tempering is time and temperature dependant, but temperature is far more critical than time.  Even a 24 hour temper will not make as much difference in hardness as 15° will... I generally do 3 x 2 hour tempers anyway, probably overkill but I like to be sure...

    That's a good looking knife, I'm looking forward to seeing it etched.

  5. Collin, I've had the same problem with mine using a Zoeller style sidearm burner (I refer to it as my dinky little burner), the temperature tops out at about 1300°... The only real difference between yours and mine is mine is vertical, and you found two barrels of the same color instead of blue and faded yellow... I also have a 2 x 4" port for the burner, which allows for a lot of room for tuning the angle and direction of the flame.   

    I see two options, either add another burner or take Sam's advise and get a bigger burner.  Since I already have a spare I'll be trying two burners first, perhaps with an extra burner I can get rid of the temperature gradient from top to bottom.  Honestly though I should probably just take Sam's advise and buy a trex...

    Edited to add, I have an abundance of satanite I plan to use to stabilize the wool with, but I want to be sure everything works as it should first.

  6. Those are such impressive devices, congratulations on getting one.  In the second video it looks like you got the steel up to sparking hot, how much control over the heat do you have?  If one of these could be fine tuned for a specific temperature, the possibilities are limitless.  Presets for tempering (yeah I know it wouldn't be practical but can it do it?), austenizing, forgewelding... Just remember, with great power comes great responsibility...;)

  7. Most tanged spears also have a ferrule that covers the end of the pole with the tang passes through, helping to reinforce the pole and prevent splitting.  One could simply slide a piece of pipe over the end, it wouldn't look very pretty but would serve the purpose.  Considering this, a socketed spear is just doing it all in one piece, and makes inletting the shaft to take a tang, and the tang itself, unnecessary.  Taper the end of the shaft, slide it on, and stick a nail in it, you're good to go.

    That, sir, is an honor!  :lol:

    I overheard a conversation earlier about Charlemagne's sword Joyese, and how Google translated it to 'Happy', which one must admit is an odd but strangely appropriate name for a sword...

    Spiffy is even better.
