I was waffling over whether or not to attempt representing spark plugs, wires, conduit and mags. I was leaning against until I found a couple of pieces of extremely thin rod, Perfect for spark plugs in 1:48. I figured go for it. I'm a modeling bench hero if I pull it off and if not I can just scrape it off and re-paint the white metal engine cyls.
After I removed the scratch built intake manifolds and set them aside, I glued a short piece of the thin rod to each cyl and nipped it close for the plugs, I painted some really fine copper wire black for the plug leads. I painted a piece of 30 thou rod copper for use as a plug wire conduit and cut a couple of cross sections of sprue to use for magnetos.
I laid the engine block over and marked the center of each cyl with a fine point pen on the white paper on my bench. This was for a guide for about where to attach each of the plug leads. With the copper painted 30 thou card taped against the marks I made, I then started CAing small pieces of the black painted fine wire to the conduit piece at the marks.
At this point I thought it wise to call it a night and allow those 12 CAed plugs and 12 wires to cure overnight before I try to mount the conduit and attach and trim the plug wires. The mags and the wires on that end of the conduit are a modeling adventure for another day.
Lessons learned, (or possibly re-learned...I forget), Best to CA bare copper wire to bare styrene rod and paint later. Oh well, there is no shortage of 1:48 engines that need plugs and wires added. I'll do it more gooder on the next one.
