Thanks for your process check and pics Jacubey. I will be leaving for the summer as I spend most my time at the gym and waterpark down the road, but here's a quick summary of the zinc method for anyone interested, its very easy, and 2 other people have followed here with great results using a cotton ball stuffed in funnel instead of vacuum. Same method I've used for a decade: Post #12 with pics:

I only do this around 3 times in a lifetime, so I have enough THH to last a lifetime, as I tend to use 300mg at least x 3 times a month. It's a lot of hard work extracting the rue. The harmaline to THH part is easy.
Now once you have your harmaline freebase...
1) place 10.5 grams of harmaline in a 1 liter pyrex cup style glass
2) add 900ml vinegar
3) add 40g zinc dust in the pyrex glass too, use 40g zinc dust per each 10.5 grams of harmaline. You will see tiny hydrogen bubbles rise to the surface.
4) place beaker solution on a magnetic stirrer with stir rod and spin entire solution slowly
5) spin for 1.5 hour, then let solution sit for 1 hour without spinning so the zinc dust can settle to the bottom.
The solution will have turned from a beginning dark green color to a transparent like golden color after it sits 1 hour after the 1.5 hour spin. Use the end of a cotton q tip to place in solution and dab on paper plate in front of blacklight, the smear will now glow light blue when transition is done...
6) Remember, once done with spin, let the solution sit for 1 hour, most (99.5%) of the zinc dust will settle to bottom, then filter solution above the zinc over a #101 9cm filter disc fitted to a vacuum flask with vacuum trap in series with your vacuum pump, this will give you a transparent golden color liquid, use this solution for next step.
Throw away any zinc dust you just collected on filter disc (be careful, don't throw zinc on top aluminum foil in garbage or it will smoke due to hydrogen loaded zinc, best to put used zinc in a baggie with water to keep it moist, keep away from aluminum).
The pump/vacuum filter flask & filter disc will remove 100% of any zinc dust. so in other words, filter pyrex beaker solution (takes out the zinc dust) over a #101 9cm filter disc fitted inside a vacuum filtration flask hooked up to a vacuum pump, with a small vacuum trap in series, in-between the filtration flask and the pump. A good pump is JB platinum DV-142N 5 CFM heavy duty vacuum pump.
Cool you are left with a 100% clear transparent with just a touch of golden very light yellow color with no zinc dust at all...now add (80ml of 10% janitorial ammonium hydroxide per 2g of harmaline)...so this means add 400ml of the 10% ammonium hydroxide to your solution...you will immediately see the thh crash out of solution as a white powder, place mason jar in fridge for at least 3 hours, the crystals will all be seen at bottom of mason jar. I like to let jars sit in fridge overnight then collect the THH at the bottom of the jars early the next morning. As you have already done quite a bit of work the 1st day.
7) you will collect 7.5 grams THH freebase on the filter disc sitting in your vacuum filtration flask once you pour fridge cold solution over a #101 9cm filter disc in your vacuumm pump, rinse THH with some hot or cold water. put filter disc of thh in a pyrex tray, scrape off and dry under fan.
8] always this will happen: exactly 75% is the yield, as I don't know why this is so...but it's a great yield still. Even in TIHKAL, the yield was similar, right at 75% as well.
9) The more zinc you use, the faster the reaction progresses, so 35 to 40g zinc means the reaction is finished by 1.5 hour.
I've looked at the #101 filter after filtration, hardly anything at all on it, truly only less than 1% of the zinc dust remains to be filtered after sitting for 1 hour.
If you don't have a vacuum pump/filtration setup: Personally, I believe the cotton ball in a funnel to be one of the greatest inventions of all time--and think it would work just fine for filtering out the remaining less than 1% zinc dust, remember 99.5% of the zinc dust falls to the bottom already after sitting for 1 hour after the spin mantel is turned off. What you are filtering is actually the less than 1% of zinc dust from the very bottom after sitting that gets kicked up back into the solution as you are decanting it off. 2 people here have said the cotton ball stuffed in funnel does indeed work to remove any lingering (less than 0.5%) zinc dust, and said their resulting THH worked fine.
p.s. I also saw an episode of "Ancient Aliens" in which they discovered remnants of zinc dust inside one of the chambers, and they believe the Egyptians were making hydrogen gas using zinc and vinegar, speculating that the great pyramid was some sort of power generating device.
Pic 1: One way to make tetrahydroharmine
Pic 2 (not shown): Dissolve your rue hcl extract into warm 120 degree F water so it all dissolves, drop in two high precision PH meters, start the spin mantel, and add drops of 10% hardware store ammonium hydroxide until you reach ph=7 when the harmine only will fall out, ph 7.1 to ph 7.9 = small middle fraction of harmaline mixed with harmine, put away and save for a rainy day when doing another extraction to add back in, ph 8.0 and above = all the harmaline only.
Pic 3: 75 grams of pure tetrahydroharmine, will last me a lifetime, more valuable to me than any gold, never depart with. Pure THH glows blue under blacklight when a bit dabbed onto vinegar soaked cue tip and smeared on plate under blacklight.
In order to create the 75g very pure THH that will last me a lifetime, here a few pics of the end stage. Just follow the "Tao of rue extraction" here, or something similar to get to the ending stage where you then precipitate pure harmine & pure harmaline following instructions here.
pic 4: 274 grams rue salt, 200 grams of this rue salt was used to precipitate the below alkaloids, rest put away.
pic 5: 23g pure harmine fb precipitated at ph=7.0
pic 6: not shown: 5g middle fb precipitation (ph=7.1 to 7.5 is a small precipitation of harmine with some harmaline mix), put away to save for a rainy day when you do another rue extract, to add back in, to further separate.
pic 7: 116g pure harmaline fb precipitated above ph=7.5.
pic 8: 75g very pure tetrahydroharmine fb made from 100g of the harmaline fb (around 75% yield, similar to yield in TIHKAL, which was also 75%). But the conversion uses all over the counter chemicals (ammonium hydroxide, vinegar, zinc dust) unlike the TIHKAL synthesis.
pic 9: top to bottom: Sublingual Ayahuasca: 300mg pure THH taken 45 minutes earlier orally, 35mg harmine fb, 35 x 7 or 210mg HPBCD to complex the harmine in 3 drops boiling hot water, 150mg dmt fb, 150 x 7 or 1050mg HPBCD to complex the DMT in 12 drops boiling hot water.

If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
