Spark Plug

[JerseyBill]

Hi.

My last post to introduce myself!

Never one to duck a challenge I responded to my eldest son's a couple of years ago when he suggested that making a pen out of a spark plug would be difficult!

The ceramic cannot be machined using "normal" tooling - so I cut the plug body in half and extracted the central ceramic part. Then I made replacement parts using acrylic and stainless steel.

The ceramic element of the plug is replicated in ivory acrylic and a home-made transfer is then applied and lacqured. Inside the body is a credit card tube and mechanism. You remove the screw-on terminal and twist the plug body to extend the pen tip.

Now THAT is bloody outstanding engineering at its finest
Seriously well done, would never of thought of even trying to convert a spark plug, brilliant, simply brilliant

Nice job. As a point of interest you can drill ceramic with glass drills. They’re available in a good range of sizes and aren’t expensive. Alternatively if you wanted to use real ceramic there is a machineable ceramic called Macor, but I don’t think it’s cheap.

Thanks William. Didn't know any of that - food for thought and investigation!

Cheers!
