Anyone have Any tips on how I can turn one of my Becker BK-9 blanks into an un hardened blank ? Nobody wants to grind a hardened blank ..lol
 
you will need a forge or a heat treat oven to get it hot enough to anneal. you might check with peters heat treat and see if they can anneal it.
 
Get it hot enough to where its nonmagnetic. You can use a mapp torch, you just need to make sure its heated even along the blade. How many do you have? Ill do em for ya if you sell me one!
 
shoot me an email Silverthorn

Ok to the people that I have been looking at sending blanks too, would you be cool with them being annealed already ? or do you want em as is ?
You know who you are..lol
 
Annealed if you got something set up with KFU for it. Let me know the details.
 
No takers on grinding out the hardened blanks eh? The polishing certainly takes way longer. But it's still doable. Sheesh. That is all. :D
 
did someone say anole?

super hilariouspimpstatus yet again !!!! somebody stop him !!!!!!!!!!!!! :)

I would not attempt to anneal these with a mapp/pro torch they are to long/thick, worst case scenario hit them with an oxygen acetylene torch.. best case scenario have a pro that's well versed in metallurgy do it, it is after all a science... :D many factors to consider.........................

to me it would be more advantageous to post HT grind, and fabricate the blade, rather then anneal, normalize (pending annealing parameters), heat treat then temper the blade, there are makers that "only" grind after HT.. you need to have one of them do it you can email me for a few names if you'd like, or if you want to dump them that's a whole other story, but if it were me, I'd have them ground.. "as is" my .02cents, make sense?? :D
 
a pizza oven can run hot enough to anneal...

or the self-clean cycle on an oven?
 
I'm not sure what a pizza oven runs, I'll assume its convection.. but at the least we're talking about 1350* +, thoroughly in one shot.. then we have grain growth and a slew of madness to factor in......

that high? wow. i'm thinking 950 dF at most for a typical coal fired pizza (or converted gas oven)
 
I would try to file one to a convex taking it slow and easy. You'll enjoy the knife a lot more if you craft it with pride yourself. It's worth a try, as you have extras.
 
Ugh to the filing idea. I kinda doubt you could get a file to grip on hardened blanks. Takes long enough with a grinder.
