Dial Bore Gauge

[TriniGT]

Has anyone heard of them and will it be good enough for use on a rebuild. It is graded up to 0.0001" and is electronic to leave less room for error. I am not sure on the brand but being that it is down to 0.0001" I am thinking it has to be fairly accurate and should work on both rods, cylinder bore, and the mains as well. What do you guys think?

You will also need a set of micrometers to qualify the bore gauge.

And just because it's digital, does not mean it is more accurate. Tap in on the bench and it could go out of calibration. Same with anything really, I just like to be able to see the dial so probably just personal preference really.

If it's a bore gauge, then it will probably only go down to 2inch (50mm) which means you won't be using it on any RB engine really. It will only do the bore, or the mains. Or the big ends on a 30 but with no bearings in place.

Spend the coin on a good set of Mitutoyo micrometers from 1-2inch and 2-3inch. Let your engineer do the bore work

And to add to that, any bore gauge under $500 I wouldn't trust

Don't worry about dial bore gauges or digital bore gauges get a standard telescopic bore gauge. you'll need a set do do all the work your talking about and then a set of good micrometers.

make sure you know how to use a bore gauge too... it's not as simple as hold it where you think is perpendicular.

failing that use a ruler and have a guess

these are more accurate than what you pictured, but they are a lot more expensive.

lol we use the same mics at work! Not wrong about the exxy bit either! Though they are good!

Alright how about this set for inner measurements?
