Plastigauge?

Where can I find some plastigauge for assembling an engine? I need to find it locally.

Thanks!
 
I have some for free, if you want it. I live in Troy and I'll be going to Louie's Pizza at 9 and Dequindre around 7, if you want me to bring it. I forgot where I bought it, but it was only $3...I may have bought it at a NAPA store...

Thanks - sorry I didn't get this til now! Had a zombie birthday party to be at by 7:00. Heh heh...anyway.

Great pizza at Louie's! (Loui's? they spell it weird on their sign) Maybe we can have a MM meetup there sometime!!!! :D

Thanks again though and I'll check out NAPA, there's one nearby.
 
Please dont use plasti-gage. Its a very old method of measuring clearances. You can get it from any auto store but a set of dial calipers works best.

Snap bore gauge and dial calipers will work much better.

Please tell me your kidding. You'd actually measure bearing tolerances with a set of calipers? No chance in the world for consistency and your instrument measures to the nearest .001 which isn't nearly acurate enough.

Please do yourself a favor and go to production tool or J&L and get the cheapest 2-3" Micrometer they have. Try to get one in that reads to .0001 rather than .0005, and for the love of god don't use plasti-junk. Even if you don't have a good feel, which as a new guy you won't, many mic's these days have ratcheting thimbles. So they will apply the same pressure every time, which aids in accuracy and consistency.
 
I've got micrometers good to the .00005. A good set of calipers will measure to .0005 with accuracy.

But you can't get true diameter with a caliper. At least with all my calipers, the teeth that measure inside distances are slightly offset, so they are a little offset from a true diameter. When you are trying to measure accurately enough for an engine, I wouldn't count on this.

The absolute best way is to get a good machine shop, and ask the guy to measure them in front of you when you pick your stuff up.
