Need advice on heat treating 80CRV2

Oh wow, I have never seen a rack like the one Luong just posted. Well, if it's something like that, which I never would have imagined anyone using, then yeah, that's a possibility.

Was the rack fully heated when the blades went into it? I would think if is was heated fully to the same temp as the kiln before blades were put in, it wouldn't have much effect? Or are the blades cooling the rack down when they go in, slowing the heating process?

I preheat the rack with the kiln and it goes up to temperature along with the oven. I also let it preheat for at least 20 minutes. If the blades are cooling it down, I don't know. I hadn't considered that.

I'm likely a bit out of the way. I'm in central IL. I am trying to move it asap as I need to free up some space in the shop, and it sounds like a couple other guys are interested in it as well. I'd recommend checking facebook marketplace. You can find a nice old Wilson for not too much money

For sure. I appreciate your offer! I was looking at marketplace and there are quite a few available. Are there any particulars that I need to watch for when purchasing? Or anything that I need to avoid?

Yeah, I picked up a Wilson 1JR for $325 last winter on Fb marketplace! $23 cheap indenter, some tuning and it's dead on. Got a few anvils and test blocks with it, too! Look for ones that have the entire weight stack, or make your own "stack" and hanger. Indenters are easy to pick up, too. Amazon and Ebay have them all over.

I have scans of several older manuals that talk about the calibration/adjustments to make, too!

I appreciate this. I wasn't sure what to look for or what to avoid when shopping for used ones on marketplace. So, I'll keep that in mind. Thanks!

That's the rack I use. Do you think a longer soak time will help? I have been preheating the rack in the oven beforehand.

20+minutes soak would ensure blade in the middle aust properly. There are 3 main factors need mitigation to resolve heating issue: radiant occultation, flow(gradient air) restriction, rack divider mass.
or easier just use standard ht rack.

Make sure it reads in rockwell C. Before you buy one, feel free to send me a message with the link to the sale and I can confirm if it is the right thing
