Re: Band heater vaporizer.
I've been following your progress on the forums. I purchased some Tempco band heaters (NHL00158) that are 1-1/4" and 250 watts (120v AC). They fit over the 1" copper pipe caps perfectly although the price is ~$25 each http://www.tempco.com/Catalog/Sectio...ica%20Band.pdf
I'm going to try and use some silicon rubber corks on mine and see if they can withstand the heat. I've got some PID temperature contollers and thermocouples I'm playing around with also. I'm powering mine with a 750 watt inverter and a 22ah battery. I guess we'll see if the temperature contollers are necessary...
If you only have a hammer, you tend to see every problem as a nail.
