Seem like a good opportunity to use a VHW Glass Heater Cover.

Egzoset said:Maximum temperature?
stinkmeaner said:Wow that really looks better than the old set up with the giant dimmer. To get an idea on how hot you are running the element, what number are you keeping the dial at?
The listed temperature is the temperature of the soldering iron tip, not the element itself. Temperature regulation is also completely inaccurate once the wand has been stripped down for use as a vaporizer. It's my assumption based on my own experience with the 936 that not having all of that metal(Tip, external heatcover, and internal heatcover) in place allows significantly more heat to reach the thermometer. The system adjusts by significantly lowering power. Personally, I have my 936 set for 896 degrees, the max setting, and the system manually recalibrate to the highest setting. What should be disastrously hot doesn't get hot enough to combust the materials in my SSV wand, despite intentionally trying to.Egzoset said:I finally found the web page where the numbers are made available by this manufacturer:
At 6 the temperature would be around 390C (733F) at the tip or the iron while at 7 it should reach 427C (800F) - but keep in mind there's no iron tip...
The element's cynlindrical shape is far from ideal for heating air efficiently, on the other hand there's no tip in your application. Euh...
I suppose we can assume that the air which hits your favourite blend has a temperature somewhere near the 390C - 427C range but i have to wonder if it's higher, lower, and by how much. A radiator with many fins to maximize surface contact would provide better heat transfer and hence probably heat the air more quickly too (and perhaps more accurately because of the added thermal mass).
Which makes me think of another question: what's the power rating in Watts?
Is it sufficient to compensate for temperature drops between inhalations?
Finally, i can't but notice that the circuitry includes two potentiometers. Imagine if their purpose were to set the minimum and maximum temperatures... By ajusting them it might be possible to gain accuracy but the picture is too blurred to get more hints from the details. I don't know if that assumtion is correct but if it should happen to be then each step can be made much narrower than the present 19C (66.6F) span!

so 500degC max
Egzoset said:Temperature sure remains the main unknown parameter here despite all of the guessing but i was also curious about the iron's power rating (Watts), in case a reader might want to experiment with whatever is available locally...
stinkmeaner said:Here are some better pictures of the Goot iron, some of which show the PCB assembly. I would think the Goot would be an excellent choice since they are in the same range as Hakko.
Hakko surely rules the Marijuana community but they definitely don't rule the high end soldering applications, that position is held by JBC, ERSA, Pace, Metcal, and some others. So there are endless choices for some nice irons to adapt, some of which have external thermocouple wires, these wires could possibly be attached to the inside wall of the glass heater cover for a more accurate temperature reading.

Here is the Ersa I like, check out the wire thermocouple wrapped around the shaft. I would strip it to the ceramic and attach the wire on the inside or outer part of the glass.

stinkmeaner said:I intern at a company that has soldering irons of all make & models. I have not used the Ersa that I pictured but I have used the stations and they are excellent made in Germany quality. There is a company in Spain called JBC that makes a adjustable temperature model called the SL 2020, they make some of the best stations right now so I figure the variable temp in handle version should also be pretty good. The JBC is about half of what the ERSA.
