Step One - Making the wire frame
For a aircraft marker get a length of wire and wrap it around the 1/16" rod with one short and one long end. Use a pair of pliers to twist it until it is reasonably tight
(you still want to be able to slide the wire easily up and and down the rod).
For a vehicle burning marker, create a cone shaped wire frame. Then get a hotglue gun and place a blob of hot glue onto scrap plastic (or something else where you can pop
off the marker later) and press the wire frame into the hot glue. Add a bit more glue if required to create a reasonable sized base. I pressed a small piece of metal sprue from a
figure into the glue straight after the wire and while the glue was hot, to give the base more weight (I'm not sure if this will make a difference or not but I thought I would
try).
