  1. Mete,


    I might be wrong but I don't think that anyone has even seen an atom.



    Hey! I've seen an atom! This reminded me of an article I read a while ago, and I found it here:


    IBM Logo made of atoms



    Pretty cool, eh?



    I see your point, Mr. Graham... although I'm not sure if mete means to come off sounding as condescending as his sometimes does. There are lots of instances where certain personalities drive me completely nuts on these forums, but I need to be on them -- if for no other reason than to temper my own views with those of others.


    BTW, did you mean that chapter in Verhoeven's text titled "Control of Grain Size by Heat Treatment and Forging"? :blink:

    D'oh! I swear, I did read it... I just somehow managed to forget that incredibly important part! Man, am I a sad example...

  2. Please guys, I value the posts of both of you WAY too much for this to become heated, or adversarial.


    You're both saying the same thing, just expressing it using different 'languages'! I'll admit that it's an awful lot for the engineering community to expect us to gain fluency in their 'language', but I also know that I have a much better understanding of what's happening because I'm trying to learn it!


    Everyone needs to remember that we frequent these forms to exchange information. Sometimes language barriers exist, but we can't allow them to denigrate our discussions!

  3. I understood all of what Mete is talking about from Verhoeven's paper, a whole chapter dedicated to it.


    Guess I need to review it, eh? I would be a great deal like me to miss it entirely, or just fail to fathom what was being said until after it's pointed out to me! No doubt part of the problem is the amount of time it took me to get through it... I'm sure half of it has been lost to me already.


    Regardless, thanks for your patience, you guys! This stuff is not very light, or easy to absorb -- and those of us that have no technical background struggle with a lot of this!

  4. ....Matt, this is all about nucleaton and grain growth. Normalizing gives you a certain number of nucleation sites ,quenching would give you more .Cold working in the pearlite range would give you more also.



    Thanks,mete! Interesting... none of this was mentioned in Verhoeven's text, which I finally managed to slog through. I'm stunned that I haven't managed to stumble across it anywhere else (other than the obvious!). Does anyone have a link to a thread or something that might give me a bit more insight? I find this stuff fascinating, but there are not too many centrally located sources for this information (at least, other than Verhoeven's paper or that I've managed to find in the last 5 or 6 months).

  5. Do the three post-forging quenches THEN NORMALIZE!


    Have you experienced significant reduction in grain size by multiple quenching, enough to justify it? Very true, you could achieve grain reduction this way, and eliminate internal stresses through normalizing cycles afterward, but is it really better than just normalizing?





    BTW Karl, were you at Ashokan last year? I'm wracking my brains trying to remember if I met you there, and it's driving me nuts! I spent a bit of time speaking to Jerry Rados (interestingly enough, about totally non-knife related things) , and your website mentions his prominence in your knifemaking.


    Regardless, your website is fantastic!

  6. I think it looks great!


    Your descriptions of the 'process' are perfect... a great blend of cold facts and a dash of romance to keep it human and interesting to those that couldn't care less about the addition of chromium in the alloying method!


    LOVE the little integrals... they're gorgeous!

  7. Earlier today I was trying to describe the knife clamp I made for using the patented "Don Fogg Sanding Stick Method", and couldn't seem to properly elucidate myself.

    Therefore, I set about taking a bunch of pictures of the stuff in my shop, and how I've modified things to work better (I hope!). Besides, it was through the postings of others that I managed to scavenge as many of these ideas as I have.

    Hopefully, these will help someone else. all comments are welcome!

  8. I'd love to see the papers, too!






    The first sentence of the scope sounds great from a knifemaker's perspective until I remembered we have no control over the "function of the component" part, which is why we have to anticipate occasional use as a prybar or screwdriver or hammer in our knives...


    "Heat treatment aims at establishing within a component a microstructure that is able to withstand any loading conditions that arise from the function of the component."



    I've never gotten the prybar argument, though... why is it that a knife is expected to perform tasks outside of it's 'function'? I mean, I've never seen a sharpened hammer. That's called an axe, and as such isn't a hammer anymore, right?


    I get into this discussion with one of my best friends all the time. He asked me about whether or not a particular wooden handle would be better than another for a shovel, because twice a year he breaks them... using it as a prybar to pull big stones out of the ground! The response from him as to why he can't go back and get the 6' prybar he has sitting in the shed is always the same, too - "I meant to bring it." or "I didn't want to walk back." Is this really a failure attributable to the shovel?


    I know this is a hot topic, and I'm not trying to start a fight... in fact, I'm questioning this on Don's forum because there's a lot more level heads and reasonable people present here than in many other places, and maybe someone HERE has the response or insight that I'm missing!


    If this is too far off-topic, tell me and I'll start another thread... or I'll shut the heck up, whichever general consensus prefers, as this has been hashed and rehashed forever.

  9. I've just been a slacker



    Slacker for sure, man... jeez! :D


    Just because you need to work with no sleep because of baby is no excuse! The knifemaking community demands more! :wacko:


    Can't wait for the shindig man... you know the deal, if you need something get in touch with me!

  10. Hi Don,

    I just got an email from Dick about this, and he was waiting to announce it fully until he had sign-up sheets/waivers ready... appears that the cat's out of the bag, though, eh?


    Ought to be a good time! As soon as I get Dick's permission (assuming he doesn't post here on his own, of course) I'll provide further details!

  11. Yep, Sam... it was one of the best experiences of my life!


    Mike sissied out last time because of work, or something ridiculous like that. You'd think that he'd be willing to give up a good new job, or leave his gorgeous fiancee for something as important as Ashokan, tho... :blink::D


    Anyway, since attending Ashokan I had to relearn everything I thought I knew about steel (which turned out to be not much, and mostly garbage based on myth and old wives tales). Truly an incredible experience, where I met a lot of great people and learned like you wouldn't believe!


    Sorry for the off topic, Mikey! Gorgeous blade... truth is, I've kind of come to expect no less from you, tho... you set the bar really high for yourself, and always manage to clear it effortlessly!

  12. I won't miss Ashokan under pain of death!


    There's never enough time for everything we WANT to do, though, is there?


    You know, you could come out and visit me, too, ya know! I've got more than enough room, and I live in one of the most beautiful areas of the Northeast Tropical Rainforest!


    ... I won't make you sleep in the truck, either! :P:D

  13. The one drawback I can think of is: how would you heat the oil? Most quenchants need to be brought to 130-150 degrees F to work at their best.


    Now, if you could come up with a "heated dumper", I'll bet you could find a market for it -- as a quench tank or a toilet!


    .....aaaahhhhhhh niceandwarmmmmmm...... :D

  14. Positively awe-inspiring!


    It's unfortunate that you won't be the one to complete the work, however... blades such as these-- that obviously speak so much of the bladesmith's heart and soul-- should be finished by a true artisan such as yourself!


    Amazing work!
