STAGE 13

 Return to the BUILD


“This stage returns to the cylinder heads, where you’ll fit caps onto the distributors and then connect the spark plugs up with their cables. You can fit the spark plug cables to both cylinder heads at the same time if preferred.”

Parts

Materials: The Distributor Caps and Attachments are plastic. The Spark Plug Cables are PVC hose.

Build


NOTE: As we continue begin building our Miura’s V12 engine, refer to this image of the completed assemblies as needed to identify the various parts and attach them in the correct locations:

Fitting the Distributors

Step 1

Retrieve your two Cylinder Head assemblies from Stage 10. Press the two pins of each Distributor Cap onto the Distributors of each Cylinder Head. The small pins of each Distributor Cap should be facing towards the top of the Cylinder Head, as shown by the yellow arrow below:

Attaching the Spark Plug Cables

Step 2

Starting with the Cylinder Head (Left) assembly, slide one end of a Spark Plug A Cable onto the topmost pin of the Distributor Cap. Slide the other end onto this sixth ‘spark plug’ pin at the far end of the Cylinder Head, as shown. Use tweezers as needed.

Next, slide one end of a Spark Plug B Cable onto the next pin over of the Distributor Cap. Slide the other end onto this fifth ‘spark plug’ pin of the Cylinder Head, as shown:

NOTE: The Spark Plug Cables are designated from A to F in descending lengths with the ‘A’ cables being the longest and ‘F’ being the shortest.

When it comes to engine hoses on my partwork models, I like to slide a slightly shorter length of 22 gauge Craft Wire into each one before I install it. This allows me to bend the hose to any shape I like and it will stay that way:

I also use a tiny bit of super glue at each end to keep the hoses in place. Here I have connected Spark Plug Cables A & B to the Distributor Cap. If you find these pipes are a tight fit, try using the tips of your tweezers to gently widen the ends of the hoses first:

After bending the wires into shape, I glued them onto the appropriate ‘spark plug’ pins, as shown:

The rest of these wires are attached in the same way. Slide one end of a Spark Plug C Cable onto the next pin over of the Distributor Cap:

Slide the other end onto this fourth ‘spark plug’ pin of the Cylinder Head, as shown:

Finally, slide one end of a Spark Plug D Cable onto the last pin of the Distributor Cap:

Slide the other end onto this third ‘spark plug’ pin of the Cylinder Head, as shown:

Step 3

Press the two pins of a Distributor Cap Attachment into the matching holes at the end the Distributor Cap.

The two pins are different sizes so this part will only fit correctly one way, as shown:

Step 4

Slide one end of a Spark Plug E Cable onto the topmost pin of the Distributor Cap Attachment:

Slide the other end onto this second ‘spark plug’ pin of the Cylinder Head, as shown:

Then, slide one end of a Spark Plug F Cable onto the remaining pin of the Distributor Cap Attachment:

Slide the other end onto this first ‘spark plug’ pin of the Cylinder Head, as shown:

Step 5

Repeat Steps 2 through 4 using with your Cylinder Head (Right) assembly:

To make room for the Carburettor assemblies, I recommend moving these wires towards the side of the Cylinder Heads with the Distributor:

Thoughts


Working with these Spark Plug Cables can be a bit fiddly as they are actually tiny PVC hoses. Using tweezers and even magnifying lenses made a big difference. But, in the end I think they look great!
