I have good news, and I have bad news.
Good news: the cooling coil works
Bad news: the cooling coil works
I like cool vapor. I'll keep using it.
@Korgminilogue Here are ways to make attachment to black upper chamber without using cooling coil.
First in two pics on left is an 18mm female placed over the chamber.
Picked up one up in a shop. Loose fit, not good seal bareback.
Ordered cheap high temp half inch ID O-rings on amazon.
Adapter rides on top of O-ring, easy to lift off -- too easy.
If you use direct draw glass like on LSV, better use keck clip.
If I had half inch ID silicone, might make a tight fit.
We need a pro's input here, like @evil 55 or
@lazylathe
@elmomuzz was rockin a hydratube on the Plenty a couple years back.
A really snug fit can be had using 14mm male connection like in the third pic.
Same silicone used when metal coil snugs in.
You could directly attach silicone whip (3/8 in ID 1/2 in OD) to this.
That cool Oregon carbed glass adapter uses 18mm female by default, but I'm sure he would make one with a 14mm male.
The last pic on right I did as a masochistic goof. It's an Ascent 14mm water tool adapter.
Wanted to experience a direct draw without cooling coil.
Pinch on screen, weighed 0.06g.
Started drawing as temp rose, testing discomfort, acting like a girly man.
It was warm. Forces you to slow down your draw, which aligned quite well with my recommended slow draw with micro loads.
After a few draws, I went for level seven. Now that was hot. Vapor and glass tube. Level six was better.
I'll stick with using the cooling coil.
