CLEANING SHOVELHEAD
For cleaning the shovel head, I pull some hot air through it to make the titanium hot. Then I take out the screen, and use q-tips or pass a towel through and shimmy it through the pieces. Of course also taking the 2 pieces apart as well. I then use the NV wooden brush to clean the crevice the screen sits in, then q-tip once more. I then hit the screen with a torch while holding it with scissors and get it brand new. Screens last me ~5 months doing this 1-3 days. These double weaves are insanely good. They also make you bust a lung and your hits suck if you aren't on top of cleaning them. I find ISO soaking the screen leaves some bits in sometimes, requiring some digging or brushing.
I know screens will last longer not torching, but I value efficiency over a few dollar screen once in a while.
If you throw on a pair of vinyl gloves you barely feel the heat. Otherwise, I pull some hot air through it, and let it sit a minute or so to allow the outside TI to cool enough to comfortably handle. The inside tube should still be more than hot enough to effectively q-tip. If you have heavy build up you might need to heat it a little more or use multiple q-tips.
This takes a couple minutes once you get good at it, and requires no ISO, just some heat and a cleaning material. You can use any brush for the screen crevice, but honestly it doesn't affect taste that much if you skip this nook. This method will get it 100% clean as we're just dealing with vape reclaim.
I do this every 1-3 days depending on use. I clean my pieces every day, but I'm not as much of a stickler about the shovelhead assembly. The trick is doing this OFTEN. You have two choices:
- Let your stuff get really nasty and make it hard to clean
- Clean it very frequently, which takes time, but it's super easy and effective
I choose #2
TERP PEARLS
As for the terp pearl tests, a full dish actually sucks, and I've found myself sticking with 7, which fills half of the VROD dish perfectly. Anything over that, it starts to get harder to effectively q-tip the dish after hits - if you need to. The full dish did a good job extracting smaller dabs, but when I tried a bigger dab and there was some residue, it was impossible to clean it.
Another side effect of a full dish is your heat drops noticeably quicker and also seems to not get to temp again as quick. This is much more surface area so it seems to make sense.
It's also rather hard to spin the higher pearl count, at least with my 1 hole angled VROD cap. I'm using an 18mm that has serious chug, and they barely spin with a full dish. 7 spins just fine. I think this also comes down to, since the dish is full, there isn't a "side" of a pearl the wind current can hit and push them. It kind of just bounces over the top of them I guess. 1 or 2 less pearls than full didn't really help facilitate spinning, though.
So my verdict as of now is: 7x 5mm SiC terp pearls is the most efficient in my VROD dish. Temp = 689f with a very strong pull.
