Using a Bore Gauge

Bore Gauges are an affordable entry into precision work. Bore Gauges can be set to an object of a known width, a comparison between the known width and the bore itself can then be made. This video demonstrates using an outside Micrometer to establish the target bore size. Any difference less than, or greater than the zeroed indicator is your actual bore size.
There are many methods for measuring a bore. Bore Micrometers for instance require less practice to use effectively, but they only cover a small range of measure. For repeated measurements, a Bore Micrometer is a clear choice for the ease of use. The cost of covering the same range as this Bore Gauge set (.7000" to 6.0000") would be a considerable investment.
If you are considering entry into precision measuring, a Bore Gauge Set and Outside Micrometer Set are a sound investment. Adding in a Gauge Block Set is also a great way to accurately combine the use of all three sets of tools to calibrate one another.
I hope this video helps get you started , like anything as a Machinist, we learn as we go.

Love the longer more indepth videos👍 keep em coming

[@OctaneWorkholding]

That is great to hear! Hopefully someday soon I can pick up an actual camera and capture more of the surroundings and multiple angles.

[@billchiasson2019]

Great video!! You did an awesome job shooting this!

[@OctaneWorkholding]

Thank you! Appreciate the support!

[@robhurley5258]

Nice job, thanks.

[@PrateekKumar-mi5hk]

New to the channel, great video. I have the same bore gauge (511-733) however, I'm missing that measurements sheet I can still work without it but it's a lot of unnecessary trial and error. Could you please post a scan of that page (even a photo will do) here or the video description? I can't find that anywhere, not even on mitutoyo website.

[@Jayjam209]

Oh yea! Always love your Instagram content. Just subscribed. Can't believe I missed when you came over to KZbin. Great stuff thanks for sharing. I am about to binge watch your videos. Cheers.

[@OctaneWorkholding]

Thanks for the support! Glad you made it.

[@koichi8903]

You have saved me from failing my high school robotics class.

[@ViceChief]

Hell yeah, Octane on KZbin! Thanks.

[@OctaneWorkholding]

😁 Many videos planned for this year! Thanks for watching!

[@HighCaliberCraftsman]

Nice! Just subbed!

[@OctaneWorkholding]

Awesome, thanks!

So the little hand are increments of .002 ?

[@RajeshSharma-yo9px]

Good

Would you prefer the analog or the digital version from this bore gauge from Mitutoyo?

[@gobble_gang]

Analog is typically higher accuracy for this stuff! Not only do you get the seperate tenth increment lines, but you can see where in bewteen each increment the dial is at. Additionally, it's way easier to visualize runout on an analog as opposed to digital, making it a faster reference. But wait! There's more: you need to hold the tool very precisely to get an accurate reading, and you have to feel for it. An analog gauge makes way easier to feel for the perfect perpendicularity, which makes it even easier for getting good measurements.

where can I get that bore gauge set ?
