I am fineley building my super quench tank and had a question. Do you think having a cooling function on the tank is a good idea. It is electric heated with a temp gage so i can see what the temp is at. I rareley do more then one knife at a time and was wondering if it was worth th effort to run cooling coils inside the tank. i then would pump cold water through the coil inside the oil to drop the temp. I will post some pictures later of it.
 
If you are going to be doing production runs of 20 or more blades at a time, then it would be nice. If doing just one blade now and then, like most of us do, there is no need. Oil volume is more important. Using an electric heating element is a good system to heat and regulate the oil temp. Add a small pump to re-circulate the oil from the top of the tank and return it at the bottom. This will increase agitation and even out the oil temp from top to bottom of the tank. This can help keep warping down.

I have a transmission fluid cooler in the oil recirculation line. There is a cooling fan mounted on it ,connected to a thermostat that turns the fan on at 10 degrees above the setting of the oil heater. So far it has only come on once........but it does look cool! ( bad pun)

Depending on the temperature you can get away with a small centrifugal pump, if the temp is above 200 you will have to step up to a gear pump likely, make sure if you use a gear pump you have a very good filter on the intake.
 
I am using an electric fuel pump ( auto store). You are only dealing with 130-150F oil.

well i put the oil in and plunged her in. it took about an hr to reach 130 deg, its awhile but not bad really considering its 5 gal of oil. plus i can just plug it in when i get to the shop and it will be ready when i need to quench. I will post some pictures when i get home.
