I spent a fair amount of time today trying to scratch build a ignition system for my Spit. I am astounded that Tamiya produced such a beautifully moulded and detailed kit and completely omitted the ignition leads and supply tubes that sit right on top of the engine in full view...
I failed
I fabricated the tubes and the elbow joints, 6 per tube for the ignition wires out of plastistrut 1mm and .75mm rod. I then needed to attach the braided S/S ignition leads to the plastic...hmmmmmm, what about a short section of heat shrink tubing ?? half on the plastic rod and half on the braided wire, heat it up and it should form a join between the two !!! wrong, heating it up worked for 3 joints and then suddenly it melted the plastic rod ...back to square one .
Strange thing is the kit has the tubes to carry the ignition wires on the side of the engine where they will never be seen but they are completely missing from the area between the cylinders..
A few failed ideas later...... :cheer:
I will need to try again with another idea .. when i have one
EDIT This is my latest idea
Just a laminate of plastic strip and some copper wire, i think i might need to paint the wire a sort of off titanium colour. Made a start on some of the other plumbing but most is intertwined with he engine bearers so i cant do much more yet.
