Flamethrowing Jack-O'-Lantern

Step 9 Drill holes

Use the two mounts that you just cut out as drilling guides on the aluminum extrusion.

The motor mount should line up with the long edge of the extrusion and you should use a marker to mark all 4 corner holes.

The candle mount should be slightly backed off from the short edge. Make two marks for those holes as well.

When you are done, drill 1/4" holes through the aluminum using a drill press.
