Advice to New and Want-to-be Makers

Not using my real name is my first mistake here.
Could you advise where the best place is to introduce myself as a long time maker and occasional lurker?

 

Thanks Stacey, I'll head there now.

 

Hi I am a first time knife-maker and I found a website that will quench my blade but they only accept air quenchable stock. I am using a piece of 1095 high carbon steel and am inquiring on wether this this material would fit the requirements. Thanks!

 

No 1095 needs rapid cool, best to use high speed quench oil by Houston or parks but, hot canola or heavily salted brine from water you could do yourself? You risk possible crack with water and you might not get 100% cooling rate on canola but air hardening is typically stainless steels where the continual cooling curve has a much longer window than high carbon steels like 1095

 

Hi Stacey,

just hoping you can point me in the right direction....I upgraded the membership but cannot seem to locate where I can adjust title and shop name so I can have it appear as you suggested above?

 

I’ll try on my computer later, maybe I’m just dumb lol, but I see no custom title area!

 

What are the 'Stickies' and how do I find them?

 

Oh okay
Thank you!

 

I hope i'm putting this in the right place, i'm new to any and all kinds of forums. I'm considering buying some .100 cpm 3v bar stock and grinding a blade to my dimensions and length desired. just looking for a bit of guidance on the grind angles because I would just be guessing. Solid advice about what heat treater to use would also be appreciated. I've had experience grinding a number of blades out of free scrap circular saw blades and my hand is practiced there, but it's different when messing with 50$ worth of steel.

 

this is an actual thread. You might want to try posting under

 

Posting under what? Don't really know where to post this if i'm not in the the right place.

 

Sorry not sure why that was cut off, but under knife makers discussions....although I think you need a paid membership for this.

Also there are Sticky’s as Stacey mentioned even making this post that if you do a search on the steel type you may find lots of info on without others having to repeat it.

this was a separate thread on forum usage, not intended I believe for question posting about a specific material or knife construction but Stacey is the OP not myself so I don’t want to speak for him. Having said that he references using as many details in your name and profile if your serious about this, and makes reference to sticky’s - why I tried to steer you to a different type of forum

 

OK, thanks for your help. as mentioned I'm new to forums and certainly green in this one. Just an amateur redneck trying to learn.

 

I’d try to help but I have little experien

I’d try to help but unfortunately have little experience with 3V. I have used some CPM steel primarily CPM 154. The only advice I can give is on anything less than 1/8” thickness you probably want to heat treat before grinding. I know some makers have success with thin steel and just air cooling as with stainless you get 2-2.5 min depending on the steel to skip the pearlite nose. Unlike carbon steels that need very quick temperature drops. I however due to the high austenite temps (stainless usually needs a 5-15 min soak at 1900-2000 deg, I use a kiln for this) I find even moving it around if thin it might warp.

I’d suggest a plate quench (2 pieces of milled aluminum 1.5” thick by however wide/long you want. Mine are actually 2”x5”x18” for larger pieces, but I make some big knives!) in two min with that thickness you’ll be fine and it will prevent warpage.

Then grind and polish, after temper (stainless usually lower 300’s unless doing a chopper so based on your thickness probably in the neighborhood of 300-350 at least twice for an hour but better to do twice at two hours). Watch your blade heat after tempering, when grinding dip in water often if no cooling mist set up.

ok just pulled up crucibles page...lol this is why it’s important to understand the steel your working with. They are suggesting much much higher temper temps like 1000 deg.

here’s the link but do a forum search on 3V from the forum, maybe someone here has a good deal of experience that I don’t have!
