And brass is used in commercial applications, home water supplies, and even hospitals around the world in items such as oxygen regulators. :) I guess what bugs me about this discussion on this particular board is that what originally drew me to this place is that for the most part people were...

My point wasn't to say that brass is known to be 100% safe. I am also in no way defending lead in a vape. The issue I had was people tend to jump on a bandwagon with minimal information, in this case the presumption that brass is more of a hazard than other materials, and this precursory...

Actually, a lot of SCUBA regulators today use brass extensively for the valving in the first stage regulator, and the high end ones also use it in the second stage (usually chrome plated along with nickle elements). So to say it isn't being used for life critical breathing applications isn't...

I haven't used Tygon, so I can't comment on it, but I am loving just plain old food grade silicone tubing on my SSV. For me the problem with the vinyl tubing wasn't heat issues, but rather just the smell associated with it (granted, I didn't keep it on there for long, so perhaps over time heat...

Yeah, rereading what I wrote I wasn't very clear about the valving. What I was trying to say is that on the exhaust, the check valve is doing exactly what it is designed for, allowing flow in one direction (allowing exhaust to flow out) but not the other direction (back flow through the valve...

I got nothin' right now - just wanted to say how much I love this tread :ko:

The only reason I had bowl downstream of the check valve was accessibility, as if it where upstream you would probably have to be unscrewing something to get at the bowl, and stoned + trying to thread something usually isn't a good combo ;) As for the check valve on the whip side, the reason I...

Yeah, finding a valve that will work is going to be the (impossible?) trick. I may have to be something that needs to be engineered, which could be fun if you had a few years ;) The lack of pressure on the supply side shouldn't be a problem though as sucking on the delivery side creates relative...

Hi Skippy, I was thinking about this in the shower this morning and had an idea that may me more trouble than it is worth, but I thought I would throw it out there in the interest of keeping the idea ball rolling. What was troubling be about the whole arrangement as it stands was finding a...

Wow, I need some friends like duh! That sounds like quite a party.

Got a little Mix'n'Ball Nano, fun little (operative word) grinder. Most than likely way to small for most, and really more of a novelty than a day in day out functional grinder, but it is a great size for grinding up a small pinch and sucking straight into a wand. My only wish for it would be...

It is also disappointing that their marketing manager seems to have such a tenuous grasp on how vaporizers work. It isn't a cigarette, the faster you draw the cooler the air.

Hi Skippy, You may be right and it is not needed, but the reason I suggested it is that every on demand heating device that has a variable powered heater I know of uses flow metering as an input metric for heater power. If you have your thermocouple very close to your heater, this won't be a...

If you are this intent to hold a constant temp on outlet air for a whip style use, I think you are going to need a flow meter on inlet to know when to increase current during a heavy draw. That is probably a lot more than you want to get into, but if the goal is not to require the user learn the...

Just so everyone is aware, McMaster.com sells silicone tubing with no minimum.

Don't know if people are still kicking around ideas, but here is my thought. Not sure about the text (the "There is no best" is a play on the there is no best vaporizer on the banner of this page, but as people wanted a :ninja: type shirt, I left off the vape part), but it is a start

I saw over in the stonerforums that you where unhappy with the taste off of the supplied (food grade but still elgh) vinyl tubing. I lot of people, including me, really have enjoyed using silicone tubing instead. It doesn't impart any flavor to the vapor. The down side of silicone is that it...

Hmm, I love the portability, but for me the taste on the (new) IOlite is sub-optimal, I'm getting a fair amount of plasticy on it. I tied boiling the mouth piece stems briefly, and that help a bit, but I think I need a longer boil. Any tips for reducing the IOlite fresh out of the box taste?

For the deals portion of the tread title (not really recommended seller): If you live in the Los Angeles area, Smoke Tokes currently is running a Craigslist ad with $150 for iInhale, $170 for IOlite in store pick-up only. I got mine this morning. Also, if you order online (this deal does not...

So I have been looking at the iolite as a mobile compliment to my current kit. I see that at around page 15-16 it was established that the i-Inhale and the iolite are functionally identical. My question is, it this still understood to be true, or has anyone noticed a difference? I have a shop...
