Hi Guys,
I took bo's idea and adapted it for those of us who are metallically challenged.
Plastic tube (hobby shop), plastic spoons (anywhere), grain of wheat bulb (dick smith), spray glue (hardware store), plastic glue, glue gun or epoxy and aluminium foil.
Cut the plastic tube to required length, drill small elongated hole about 1 cm down from the top of the tube, place wires of bulb down tube.
Drill hole the same diameter of your tube in handle of spoon, cut handle off spoon and dress the cut end. Slide spoon down over tube to wires and glue in place (plastic glue) and paint the whole thing your desired colour. Now spray the inside of the spoon with spray glue and place foil disc in centre of spoon (reflector), now place a dab of hot glue or epoxy to hold the globe in place ( I glued the end of the wire to the spon not the globe).
I did this and lit my circuit on Saturday morning in about 4 hours and cost $25 using 10 lights.
We held a Le Mans night race on Saturday night and they worked perfectly.
Cheers
Garry
