That's all the prep necessary for the bottom of the stove.
2.) Using the hole punch, punch 8 evenly spaced holes approximately 1/4 of an inch (or 1 cm) down from the curve in the top of the stove. Then, using the scissors, cut a line from the bottom into each of these holes. (Image 2) The holes will keep the can from continuing to split along the line that you cut. The cut lines allow you to easily insert the top into the bottom.
3.) Using your wet/dry erase marker, put dots on the stove where the vent holes will belong. Be careful to space them evenly, and put them at the same height around the top (Image 3)
User Tips: Tetrafish - To evenly space the holes you could wrap a strip of paper around it, mark it's (circumference) length, then evenly divide them...
jacksteal4 - ...just fold the paper into 16 or 8 parts [using the creases to get your even spacing]...
5.) Using the Dremel, drill a 1/8" (3.25mm) hole in the center of the top piece. (Image 5)
That's all the prep for the pieces!
