My back yard. 3pm on Sunday, July 14, 2013. PM me for address if you don't have it already. Bring your work. Bring your sense of humor. Bring your willingness to help me out with this nutty idea. Bring meats, drinks... We grill. Grunt.

This is a really good idea.
I hope more folks do something similar. No need for a hammer-in to have a BBQ get together.
 
Might try to make it. I'll know about my availability in a few days. Would be nice to meet some others that are making knives. Got family up there anyway.

I would come if it was one of two things:
1) Closer ( about 400 miles round trip)
2) Not on I-64/I-95 in the summer vacation traffic both ways ( probably eight hours round trip, IF the tunnel isn't a two hour backup)

There are a bunch of chaps up there that have been trying to get together, so this should work well for you guys. have a beer for me :)
 
Aw man, my mom is getting married on the 13th in PA so I won't be able to make this. Next time for sure! I'll keep checking in in case something changes...
 
Stacy, I also started a website for us, and I'm doing it state-wide. We all need to communicate and share info more often.

Could host in Richmond at some point and give people Liquid Nitrogen access but I don't have a forge set up and my furnaces are only about 5 inches at a diagonal.

Jim - great idea! I'll check with my "Better Half" about the schedule that weekend.

Looking forward to it!

Ted, let me know. Bring her. I expect, much like my renfaire crowd, no one will starve or have someone they can't talk to.
 
Jim, sorry for the delay, I will shoot you an email this week. My wife just gave birth to my son on Tuesday. I love the idea and website. Thanks for doing this. We really need to get organized like the boys in north Carolina are. I should be able to make meet and greet. We should do the next one at the forge in Arlington.
 
I'm going to bring up a large dewar of LN. Going to be cooking with it saturday but should have enough left over to play with sunday and maybe treat a few blades as long as the soak time doesn't need to be extremely long.

Was good meeting you all. If you guys ever need anything, just PM me if you didn't get my contact info at the bbq.

For those of you that were interested in the effects of cryo treatment, dial your BS filter all the way up and enjoy.

From asia (high probability of being a complete fabrication but might just be plagiarized) and not actually a published journal. That said, most of it seems possible.

Slightly more believable paper but notably from an industrial source and lacking error bars for all of their charts which is a pretty bad sign. Their EDS output is BS but their SEM micrographs are decent. Interesting output in terms of loss of impact resistance but again, take it with a grain of salt. Even if this data is correct for this steel it doesn't translate to every other steel.

Review paper on the Cryo treatments. Also from asia and published in an online journal (will publish anything as long as you pay them to) but it is properly referenced. Figure 6 demonstrates what I was talking about hold time. After 30 minutes it basically doesn't make any difference for hardness. Table 2 has a good breakdown on steel comparisons with different soak temps. D-2 is a rockstar at 817% wear resistance and AQS is a redheaded stepchild at 4% decrease...

If the decrease in impact resistance does correlate with soak time, and given the trivial changes in hardness and wear resistance over time. Kinda looking like half an hour is the best trade off if you care about impact resistance.
