Canna- yes please do update this I would like to see some pix of that!
Does butane and propane both purge at the same rates? Just got a blend to try from Eco green and wonder if most the variables are still the same. I'm used to working with straight tane.
Finally have fresh material to work with so I'll have to post up some results a lil later.
Auto parts stores carry vacuum pump oil. In my experience only one worker in the store will know what or where it is (usually in the back), but they do have it.
So true
I just remembered I bought an ac attachment for my air compressor for $10 at harbor freight that will work perfect for a vacuum. What all do you need besides an air hose and a pump?
A friend said they use a container like a big jar.....
whats a basic setup? I guess you mean my pump contected to the compressor is bunk its cool. Just thought it might work....
I seem to remember a dedicated hvac service pump running atleast $100 if not 200. Would these even suffice or are you talking about something like fiberglass/carbon fiber injection moldings or even something entirely differnt?

Hey G Dubb Bruddah!
I am looking and some of the vaccon's are venturi systems. Which model are you using and what media do you use with it?
Do these plug in or do you have to hard wire a pigtail to them?

will 28.3"Hg and 4.2cfm@90 psi work then GW?
A friend tried to make some butane oil and I don't think he purged it enough. He just ran the butane through into a pyrex dish and left on hot plate until it quit bubbling up. Doesnt he need a vacuum purge?? He would probably go the cheap mans route as he doesnt do big batches....
I havent done the butane oil only qwiso with winterization filtration.
Since it starts out as shatter, the better question might be how long have I purged to get rid of solvent, and still ended up with shatter.
The answer is that it depends heavily on the material and film thickness.
If the material is rife with monoterpenes, some of them have to be removed as well to obtain brittleness at room temperature, otherwise they stay pliable with the terpenes acting as a solvent.
I usually process small test amounts, so in small paddies and thin films I've gotten below 50 ppm residual in under an hour.
When experimenting with larger and thicker slabs, its takes longer. This 266 gram one took about 28 hours.
Because I increment up the vacuum and the paddy is relatively tame by the time I get around to flipping the first time, I usually only have to flip once or twice, but have flipped it more.
