Changes:

1. Used a one gallon paint can with the bottom removed as the burn pot.

2. Used the vegetable steamer as the fuel basket.  This unit is taking a real beating from thermal abuse.
It will need to be replaced soon.  All of the other parts seem to be wearing very well.

3. Removed the Webber charcoal basket.  It is no longer needed at all.

4. Rested/nested a Costco 3 lbs coffee can on the top of the 1 gallon paint can.  Fits quite nicely.
    This can had 16 full sized "church key" holes around its bottom to provide secondary air.

This is based on Hugh McLaughlin's Toucan work.  The key here is to use the secondary air flow
to shape and control the flame pattern.  In this case, 16 jets of evenly spaced secondary air, 
coming in from the sides, act to focus the thermal energy towards the center.  You can see this
very clearly in yesterday's picture of the flame pattern in the revised Sweet 16.  This version of 
the Dragon burned far too aggressively, and the flame was far too high, to get a camera 
anywhere near -- much less right over -- the jet of hot gases.

I am now using this secondary air technique with both the Sweet 16 and the Dragon.  
It works very well and is very simple.

5. Used a 28 oz can, suspended from the gas drip pan, as the focusing can.

The Dragon can now be fueled and completely set up, minus the pot of water, and then
a match can be dropped in from the top through the hole in the drip pan.  Very simple.
Safer too, as hands are not any where near the alcohol flame when it ignites.

As per usual, these pictures and notes will be added to the collection on Flickr.
