It's because it's a great thread Glab!
As to keeping a consistent temp on your chamber.
Here is the cheapest,most efficient way..
Strictly for vac purge, long after the butane is gone.
Deep dish griddle-16$ walmart
Bag of all purpose Sand -4$ Home Depot
Sand is used in the place of water. Water baths bring steam into the equation , something we need to avoid when making oil.
It holds and buffers heat much better, and does not evaporate.
Empty a generous amount of sand directly into griddle, at least 3".
Level out the sand, and nestle the chamber into the sand.
Now, take more sand and pour around the sidewalls of the chamber, essentially burying the bottom 1/3 of the chamber.
You now have a stable consistent source of heat, closest to a vac oven as possible.
I also use a meat thermometer with the probe, I place this in a fashion where the probe is in between the surface of the sand and the bottom of the chamber.
I use this to monitor temps without having to break vac, open lid and take a reading.
Simply calibrate to your setup.
For me, I turn the rheostat on the griddle to "warm" , my probe in the sand will read 138* , which translates to my oil temp being 115* exactly.
Calibrate with each run/strain, as some resins are more viscous than others, requiring an adjustment in temps.
Hope this helps
