While Okins are in the mail, I thought I would reflect on the changes since the first Okin prototype...
Proof of concept, worked OK, didn't last very long, heh.
Better. Still fairly crude and not very practical.
More prototypes, we're getting somewhere! But still a few problems.
Hmm.. maybe I'll add a box.
A better box. But still too many things inside..
A better metal tip, with two screws on each bronze prong.
New bamboo stem.
Forget the bamboo, hardwood all the way!
The production model.
Between the Beta test units, and the production units I made these minor changes:
Improved joint between steel tip and wood stem.
Steel mesh screen instead of fabric screen.
Polished inside diameter of steel tip.
Improved, darker, patina on the steel.
Hardwood stem instead of bamboo.
Improved inner airway design.
Beveled the edge on the steel tip that butts up against the charcoals for a better seal.
Improved charcoal manufacturing process, yielding more consistent charcoals, less rejects.
Improved logo design.
Added a proper charcoal drill.
It's been a wild ride! Thanks for all the input everyone!
