AEB-l question

[JawJacker]

I have looked around for answer, I somewhat have it.

Im ready to HT a 7in long 1/8 thick skinner ael-l. Should I post grind the bevel with 1/8. I know thinner stock guys like to post.
I plan to plate quench.

i would grind to 0.05", quench in oil till black, then put between plates.

I just did dozens of these - 6" to 8" long AEB-L x1/8 thick - Plate quenched from 1950F. They were ground to about an .015 edge - some with serrations. Very happy with the results. No noticeable warping. Post HT grind is awesome - but if it discolours, it got too hot.

 

[JawJacker]

Yeah I wanted to go the plate route. Did you go cryo on them? Thanks

I have my water jetted blades of AEB-L 0.70 thin HTed and Bevel grind post. I take the bevels to a zero or pretty darn close. They come out great!

So can you please tell me what sort of RC you got with the oil quench? I can't say I'm very excited to try this since Rob of KnifeMaker.ca does a super job on mine but ---- .
Thanks. Frank

Sorry - been away visiting the new granddaughter. Yes, we cryo all stainless.

Rob!

No problem, I figured. I just haven't used this steel before. I'm going to tackle some skinners this week.

 

[JawJacker]

UPDATE I did the heat treat seems successful. Preheated to 1450 tossed in the wrapped blades, took it to 1950 soaked 10 min, plate quench then into denatured alcohol and dry ice. tempered @350 X 2hr. I cant test it, but a file wont touch it. Only thing was I WISH I would have done is finish sand it more before HT

 

[Knifemaker.ca]

I suspect your blades are harder than a woodpecker's lips. (Who came up with that? I Love it!) 62+ is OK for AEB-L, but needs to be treated with respect.

 

[JawJacker]

According to my temp gun the dry ice with alcohol got down to -60 degrees. These skinners are for birds should be fine

 

[JawJacker]

The blades intended use will be for cleaning birds, Ill post a pic when I'm satisfied with it. Thanks
(didn't see my prior post)

Your temperature gun might not have accurate temperature on reading a dry ice bath. If the dry ice and alcohol bath is a good slurry, it WILL be around -95ºF - just the way it is. You need a Thermocouple, RTD, or some similar method for reading temps that cold.

Ken is right, the reflection above the surface will fool the IR reader. Just like a mirror, it will reflect part of the infrared rays it get from the surroundings.
Dull, unreflective surfaces lend best itselves to the IR measuring.
