Introduction: Titanium Plate Alcohol Stove
I found out the can was too big to heat the denatured alcohol to keep the flame lit on the burner. Once the fuel in the priming plate went out so did the flame. On top of that it would burn too hot and the flame would come out more than a foot. My solution was to heat the sides of the can with a flame which wicks up fuel. The resulting flame is just hot enough to emit a reasonable flame from the burner plate.
I don't know how long it would take to prime with just the flames on the sides. I helped it along with my torch after about 1 minute. My suggestion is not to make this from titanium. It it very difficult to work with.
Step 1: Cutting Titanium
First thing I did was use the can as a template to mark a circle about 2" on the titanium plate. Then I drilled out holes all the way around and broke it off in a vise.
Step 2: Finding the Center of a Circle
Before mounting the plate into my lathe I had to find the center. To do this I cut a paper circle and folded it in half twice. Then I used a center punch to mark where the folds crossed. I drilled a hole and mounted it in with a nut and bolt. This was by far the most time consuming part. After machining titanium, machining steel felt like cutting butter.
Step 3: Drill Out the Burner Plate
Using AutoCad I arranged 36 holes in the in a pattern. I printed the design out, taped it to the disc, and used a center punch to mark it out. Next I used a 1/16" drill bit for all the holes.
Step 4: Making a Flat Head Bolt
I could have left the bolt as is but I thought it would look better if I polished it. The lathe made quick work of it. I finished it with a file and buffing wheel.
Step 5: Retention Tabs
These tabs are bent in such a way that the lid snaps into place. It helps create a seal between the plate and the can. I cut two strips of metal and drilled them in the center. Next I crimped them around the nut in a vise (see pictures) and rolled them to shape with a socket bit.
Step 6: Can Open a Soda Can
This part is really strait forward. Use a can opener to remove the lid of a soda can then drill two holes about 1" from the bottom. Make sure the holes are just big enough for the wick to pass through.
Step 7: Placing the Wick
Twist the wick enough so when you fold it in half it wants to twist together. Next thread the wick out of the holes from inside. Tie an over hand knot at each end. Push the inside wick to the bottom so it can soak up fuel.
Step 8: Light It Up
Pour denatured alcohol into the can. Place a little fuel on the knots and make sure the entire wick is saturated. Light the wicks. Once the stove is hot enough the flame will come out on top.
