Not to the size of your oven, cut it to the size of the base of your pyrex+1.5-2" extra on all sides to allow you to fully line your dish. ex:10x10" pyrex, cut out 14x14"

Got my oven and started playing with it. So far I'm thrilled even though I totally screwed up the first test.
I have a single stage 3cfm pump, is it possible for this pump to pull too much vac on the oven? My gauge is in torr and the pump has no problem to pull to the end of the gauge, 760 torr I think. After i turned off the pump the gauge creeped to even more vac which I found odd.
Do you guys leave the pump on continuously?
What temps are you guys setting your oven at the get the actual temp inside? If I set at 115 will it actually be 115 at the racks and all around? I'm not using a marble heat sink yet.
What do you put the oil onto to put in the oven? Normal parchment?
Thanks

There are 760 torr to one atmosphere at sea level under standard conditions. Does your gauge have a calibration screw in its face?
Yes, a single stage can pump under 100 microns, which is low enough to boil THC below room temperature.
You have only radiant and conduction for heat transfer in a vacuum. Get a marble shelf to give the radiant energy something to heat, so that it can transfer to the oil by conduction, to speed things up.

You can close the valve and turn the pump off, or open the bleed valve just enough that the pump can only pull to -29.5" Hg.

So i calibrated my new controller. Its hitting the same temp as i set it for. I used the calibration equation and set my pk to -48. At first it was set to -32 so i did some fine tuning and got it right. Its very easy to do and I suggest anyone who isnt getting the temps they want to adjust the pk.

Hey guys, thanks for all this information on the AI oven.
Im confused about the -29.5 HG, i was under the assumption that more vac was better. so we were letting it go all the way to the max, 760 torr i believe. i that a bad assumption?
also we are using a closed loop system, meaning we have to get the product from the lower chamber into the oven, we have been scraping it which leads to waxing up, any ideas on how to transfer the product from the bottom chamber to the oven would be greatly appreciated. thanks guys!

Refer to the chart skyhighler keeps posting about boiling point and thc under vacuum. Going all the way to -760 can decarb your oil without/ with less heat.
What closed loop system do u use? I have a new double walled, slanted collection pot with a sample valve and stand on the way so i wont have to use the pour method anymore. If you dont want to scrape , you have to pour the solvent out after recovering all but an inch from your collection pot.

Here is one of the charts that HM is referring to from SH.

So by -29.5 hg its referring to inches mercury absolute? Which = 750torr correct? Thanks for your input GreyWolf
And im using a subzero closed loop extractor, got a 1/4lb, 1/2lb and 1lb.

Across International had them for sale on their Ebay page for about $10 but I am unable to find them now. They are definitely out there though. If you have the same luck I would suggest calling them, I have confidence that they will be able to help you.

I use a 1500 watt space heater with my ovens in a small room. $100 shelves that fall off when grazed, stoopid.

yeah, the clips can be a pain especially when running several shelves :/
what is the actual temp in your oven Icdog?

Rbe where are the best places to take a temp reading inside and with what tool? I've tried to find those thermometer strips but haven't yet.
So far I am using an infrared thermometer only. Where the readout is rock solid at 125, various places inside vary by at 10-20 degrees and product sitting on the racks is barely showing 105 after sitting in the oven for an hour.
I took your advice and just leave the oven on and it has been for a few days now.
I put my new aluminum shelves in today and am warming them up so I'll test that tomorrow. I'm hoping they make the diff.
I also noticed a different angle of the IR beam changes the temp it reads out so its difficult to use it unless I actually stick it in the oven and hold it perpendicular to what it is measuring.
