Three piece mold for sparkplug boots

[Brian Rupnow]

At some point over the last ten years, on one of my small engine forums, someone had posted plans for a three piece mold to cast your own sparkplug boots from silicone. I'd like to have a closer look at that post now, but I can't find it. Does anybody have a link to that post?---Brian

Brian,
I remember that, he made black, white and clear boots, I will have a look around and see if I can find it

Thanks Andrew---That's not the thread I was thinking of, but it shows everything I would have to know to create my own molds.----Brian

Brian,
That is not the one I was thinking about either, just the first I found, I think the one I was thinking about is on another site.

Seems to me someone posted a way to use rubber automotive vacuum hose fittings (Dorman?) to make boots on some forum in the recent past.

Yes, for the 1/4 size spark plugs. Quick, easy and cheap.
