tdc tool
BDI:
I need a top dead center tool but they are pricey so I made one from a spark plug.First I chucked up the plug in the vice you can't cut strait threw the plug because of the ceramic. You have to rotate the plug until you cut all the way around. Then I cut off the electrode. Then I taped the ceramic portion of the plug out with a punch light taps is all it takes it comes right out you should use safety glasses. Then I cleaned it up on my belt sander top and bottom. then I removed the crush washer with some dikes. Then I drilled it out to fit my dial indicator with a 3/8 drill bit I did not go all the way threw I stoped at an existing point. This would be best done in a drill press but none the less mine had a machined fit when I was done. I plan on using this tool to verify squish and finding top dead center. I will be posting about the way I plan to verify squish from now on using this tool.

thats a great idea BDI, and a real good tool. i make tools alot due to the high price of specialty tools. i think i got it from my dad. he is always making tools. when i was younger i thought he was a cheapskate for building them instead of buying them. now that i'm older i realize the genius of his ways.

I make all kinds of stuff like that. I still want to put a set screw in it but Im going to machine an aluminum coller so the screw does not push derectly on the dial indicator.
BDI:
well It's done and it works sweet. with just a light snug on the set screw it is affixed to the dial indicator very tightly and it does not leave a mark on the tool. :wink:
