One more Jen-Ken stainless visit...

I'm struggling with Evenheat vs Jen-Ken. I've read all the airbath threads I could find here. I really want the Jen-ken airbath, but the issue with stainless envelopes still plagues me.

I see two solutions: One is to make the envelope extra long and wrap it around a stainless rod. Two is to put a ceramic block at the bottom to rest the envelope on. As long as it's high enough to raise the tang up to the rods it should work.

In both cases the blade will be resting on the tip inside the envelope. But that's OK isn't it?

So for you guys doing stainless in the Jen-Ken Air Bath, how's it working out?
 
I think I’d rather use springs to hold it.
With that said, I have an Evenheat and like it.
 
I use atp-641 for my stainless and get minimal decarb, the can I have says it’s rated to 2300-2400F and I plan to test it on some magnacut and m390 very soon but it has worked very well for nitro-V at 1900F and I don’t have to mess with foil.
 
I've used NoScale2000 with good success on AEB-L in my AirBath. If I were to use foil, I'd crimp a hanging rod into my envelope, then take one of the ceramic rods out of the rack and hang the blade(s) in the space created, perpendicular to the ceramic rods. No problem at all.

Thanks. I tried atp-641 on carbon and it didn't work at all. I must be doing something wrong. Now that you mention it Bühlmann Bühlmann , I couldn't get NoScale 2000 to work either. I went back to turco for carbon, but that didn't cut it for AEB-L.

Oh decisions decisions .........

How were you applying it? If you walk through all of your steps maybe we can figure out why it wasn’t working for you.
 
Thanks Joshua Fisher Joshua Fisher . It was over a year ago when I tried atp-641 AEB-L. As I recall ....

Wiped the blade with acetone
painted it on with an art brush. It was pretty thin.
dried it out with a heat gun
popped it in the oven at 1950f

Acetone can often lead to issues because it leaves a film, I could see that creating issues where the coating doesn’t bond well. What I do personally is put on gloves and use a surface conditioning belt to deburr and clean the surface, then I go straight to applying the anti-scale with a foam brush. If I didn’t wear gloves and the surface has a bit of oil I’ll use denatured alcohol to clean it then apply the anti scale or I’ll scrub the blade with the coating wipe it off then apply my actual coat.

make this from stainless steel, red is your blade wrapped in foil

No need to make a rack and have a blade resting on its tip when they can hang like normal by incorporating a hanging rod into a foil pack fold. It’s really a non-issue, no need to engineer a solution to a problem that doesn’t exist!

ETA: Rephrased to be more neutral 😇

Because you need to make that rack just once ? So you don t need to incorporating a hanging rod into foil pack fold all over again ?

The folded end of a foil packet will hang perfectly fine Natlek. No need for a special cage.

Try to be a bit more optimistic and less contrary. A few less, "Why do you do that?" posts would help.

Got it. I'm gonna retry for sure. It would be so handy to get that working.

Optimistic or contrary have nothing with physics . The question I asked is completely correct and very logical . post *18 * prove that :)
