Some of you may have seen this already but thought I'd share it here in case it gets anyone else going down the road of better HT control. It's a brief show of how I built my quench tank. It has a thermostatically controlled heating element and a small circulating pump. I've used it now for about six months and it's doing well so far.
There's a lot in the pictures that I didn't describe, so please feel free to ask any questions. I'm not much of a writer. Or photographer.
One change to my HT process. I use O1 for pretty much everything. Using the Houghton Quench G rather than vegetable oil, I found I needed to reduce the oil temp to 120 degrees Fahrenheit. That worked to get full hardness, which I wasn't getting at 140.
