The Caldera Cone has a nice fastening. It is a genius design. Reward the designer with money.
I have already purchased one.
I want to make my own because I want to use my choice of alcohol stove and experiment with an alternative design white gas stove, as well.
I have sent for the Zelph BudLyte Super Stove for alcohol and Super Stove for Coleman gas. He used a Mountain Dew can, so I suggested the name MountainLyte.
I am using the small program http://www.outdoorsmagic.com/forum/forummessages/mps/UTN/22357/URN/5/dt/4/srchdte/0/cp/1/v/8/sp/ mentioned in White Blaze thread:http://whiteblaze.net/forum/showthread.php?t=50705&highlight=caldera+clone
I sent a "PM" to "captain paranoia". He sent me his most recent refinement on his small program.
I have windows so Ghostscript and Ghostgum are required for the little program to run.
His program allows you to change any variable you like.
1. stove height
2. height of pot above stove
3. pot diameter and pot depth
4. diameter of base
not in that order.
These are the important variables, as far as I am concerned.
I, too, like a wider base of the cone.
I also saw a convenient method to determine optimum pot height: bring water to a rolling boil in your pot on your stove, then, lift higher until rolling boiling stops, then, lower until rolling boil returns and that is your optimum pot height.
I saw that at the WhiteBlaze.net forum.
