Hey. Did someone call for Alan? u bwade wunner - The DG is working well with the HI. Very open. There is hardly any drag with the HI anyhow. Have your friend send me an email and I will get him on the list. Very funny video. BDV - I consider it just a rooster. It has no leg spurs like a fighting cock. I have a question about getting the load closer to the heating element. Since the HI center tube has no stops, it can push all the way down to the screen (actually a good way to install a screen) and make a very small chamber. Do you get more heat to the load with the screen pushed up because there is less silicone to remove heat from the center tube? I like the extra space in the bowl to stir the load which I usually do between hits. Very nice perc vids. Just give me a chance to be a glass man. I'm looking forward to making some more glass tubes. vorrange - I agree than a variable voltage is a nice option to have. I equate them to an automatic transmission for a car. It is easy for most people to learn to drive a car with an automatic transmission. Not too many race cars are going to have one. I think it is important to have a repeatable / consistent voltage. A regulated power supply should always be used. 12 volts is nice because the other available voltages can be converted down to it, plus 12 volts can be provided from a car or with batteries. I was thinking that there should be a word for the technique of moving the HI while roasting to control the temperature. It is sort of like singing or playing music when you hold a note with vibrato. Maybe holding the correct vaporizing temperature with that bouncing technique should be called " Vaprato".
