Take a look at this. Its the process written for distribution as a .PDF. This might do. The home page is significant because it has instructional videos. I cant visualize how to recreate that here. Your thoughts? (here's the pdf..)

Interesting. I didn't see a link to your site with more info, so that would be handy to point out where I missed it.
I've made RSO for some time, before my wife died of pancreatic cancer. It was also before RSO could be found easily in dispensaries. By the way, I calculated the overall cost to be about the same ($70/gram) when I made it myself versus buying in dispensaries in early days of legalization here in AZ.
Some comments and questions follow.
First, some commenting on my procedure. I used a
Magical Butter machine, up to 3 ounces of (expensive! up to $400/oz) buds PLUS some leftover vape residue to try to minimize cost. For a solvent, I used Everclear. My process was like this:
1. Dump buds, shake and some vape residue into a
Magical Butter machine along with 5 cups of Everclear. Set to the tincture setting, which if I recall correctly cooks for 4 hours at 160F. Grinds the buds as well.
2. Pour green tincture through series of finer mesh filters to try to filter out as much green stuff as possible. Same with butter or oil by the way, but I think I have less loss with tincture.
-note: pouring tincture into a tall container and waiting for a day allows a lot of particulate matter to sink to the bottom, allowing pour-off of cleaner tincture. (Works for oil too.)
3. Pour tincture into a mason jar
4. Put mason jar into rice cooker set to cook for maximum time (2 hours). Mason jar doesn't fit, so can't close the lid, but want the lid open anyway. Water boils, heats Everclear, tincture starts bubbling and alcohol gradually evaporates over the course of 4-6 hours. I do this in the garage because of fumes.
-result: thick black tar-like oil at the bottom of the mason jar. I get approximately 1:7 ratio of oil to bud. 7 grams of bud in gives 1 gram of oil out.
Because the oil is so thick, at this point I had cut it 50% with Wesson oil. That got the oil fluid enough to draw up into a big syringe (originally designed to refill ink cartridges on a printer).
Because the oil is so black (vape residue in part, incomplete filtering) it was nasty to eat. So my wife suggested putting it into gelcaps from the local health foods store. So that's what I ended up doing. I drilled a bunch of holes in a piece of wood to hold the gelcap bottoms. I used the syringe to carefully put drops into each gelcap, then put the cap on the gelcap and threw it into a plastic bag labeled with the number of drops I put in the gelcap (measure of potency) and the date of the extraction.
This way my wife didn't have to taste the gunk. She just ate the capsule and had it kick in about 2 hours later. By making several strengths of pills (3 drops, 5 drops, 7 drops, etc.) she could vary the dosage by combining multiple capsules once she determined the strength of that batch.

Compared to your method, I see advantages and disadvantages. I wonder if you could comment on the use of a
Magical Butter machine to kick off the process? And perhaps the use of a simple rice cooker to boil off the alcohol. I wouldn't want to boil the alcohol on my stove, partly because it is a gas stove, but also because it is indoors. The rice cooker can be plugged in anywhere - back porch perhaps - and it really keeps the smell down to move that outside.
Magical Butter machine too.
My biggest issue with this, beyond the hassle of getting drops into gelcaps, was the filtering aspect of this. I sort of gave up hoping for an extremely clean output when I went to gelcaps. But I'd love to know how to do better, and the brine step seems interesting there.
