So sorry to make you combust like a caveman Tom.
I will try my best to shorten the time.
Thanks for the answers mom, OKcomputer, and vorrange. The prices are still correct. I only have a couple of the thinner all glass tubes left and probably won't make any more.
You are welcome SativaLover420. I'm happy the HI is working out well. Just need to make them a bit faster.
DrPiff - I was getting vapor in about 3 minutes with 14 volts applied from my 0-15v ps. Definitely too much voltage for tasty vaporizing. No real need to go much above 12 volts.
Edit - Was reading in another thread about log style vapes not having the same air flow as whip style vapes and so I decided to do some measuring. The smallest restriction on most whip style glass pieces is 1/4". I'm not certain about the 7th floor glass. The silicone tubing is 5/16" ID.
My all glass turbo tubes are over 3/8" ID. The restriction in air flow is in the HI center tube. There are six 1/8" diameter holes into a tube with a 5/16" ID tube containing a ceramic heating element. The effective area is probably close to 1/4". This means the HI with an all glass turbo tube has about the same air flow / restriction as a whip style vaporizer. The all glass turbo tube does have more of a potential for plugging since the screen area is less than a standard whip vaporizer. Nothing a little stirring can't solve.
