How to Measure a Hole or Cylinder [HOLE GAUGE]

In this week's ToolTip, we show you how to use a Bore Gage, otherwise known as a Dial Bore Gauge, Hole Gauge, or Cylinder Gage. These work great in conjunction with the Digital Calipers that we covered last week. Be sure to check out that great video in the link below. You can get this Bore Gage set for less than $20 from Amazon.

I learned these at a young age due to my Dad being an Ace Mechanic back in the day. Became more useful when I became a Machinist. Over the years I've collected several sets of them. My favorite set is the Starrett brand I inherited from my Dad.

Thanks for sharing. Not doubt, those Starret tools stand the test of time. Thanks for watching.

Thank you for the video. I have removed my first sbc from my 84 el camino..I took apart my motor almost 2 1/2 years ago I never rebuilt a motor before but I'm at the phase in the build where I'm second guessing even if i am going to be able to figure how to put it all back together. My current status is I need to know what I have to know what I can buy. Rings, pistons, rdos lifters, camm etc. I came across your video, and it made me feel like I have a better understanding of how to use both tools you referenced in this video. Very clear, and I understood how to do it myself at home for a first-time builder. Thanks, and you got a subscriber for this one

[@blakenorman4822]

just used these to check bearing clearances on my crankshaft mains, worked great

[@toolsdo2570]

Love your video, thank you.

You are so welcome! Thanks for watching.

Thanks for your useful information

[@Shoptoolreviews]

Happy to help. Thanks for watching.

Nice video Great personality

Lock it down at a angle and in one motion, rock it out. Record the measurement and repeat the reading until you get 3 that match. This ensures a proper reading. Millwright 101 :P

Telescoping Bore Gauge, a.k.a. Snap Gauge or Telescoping Gauge. You also have Small Bore Gauge or a.k.a. Hole Gauge. These are full & half ball gauges.

[@Shoptoolreviews]

Very good advice. I'll have to share this soon. I admire you machinists. Thanks for watching.

Cool Tip Tim 👍

[@Shoptoolreviews]

Glad you liked it! Thanks for watching.

Have you reviewed the m12 fuel 2- tool combo kit 2598-22?

[@fulltakestevens1205]

How do I get those tools big man?

[@MattJonesYT]

How important is it that the ends be polished? I noticed many of the amazon reviews for the $20 sets mentioned that the ends were rough or pitted and therefore not accurate enough to be useful. Could you just buy a $20 set and polish the ends to make it like a more expensive one?

[@Shoptoolreviews]

These were definitely not pitted. You can polish them, if you wanted. It won't affect the performance of the tool. Thanks for watching.

[@neolithicnobody8184]

The finer the finish, the more accurate the measurement. Yes, you could polish them, but you would also have to calibrate it if possible. This would also depend upon the severity of the pits. Polish too much and calibration could be too far out of spec to recover. Gauge blocks are a great example of polishing to accuracy. Using the Wringing Technique, two blocks can form a vacuum between themselves, making them stick together like they were magnetized. Normally, with tools like these, you get what you pay for. Or in my case, I inherited them. A 1950s set of Starrett tools including these with micrometers, calipers, depth gauges and more.

[@SonofJacob120]

I often hear people talk about 396,427,454 are those the cylinder bore diameter?

[@twinturbo3470]

Those are engine displacement sizes in cubic inch. A V8 6.4L ( metric) is the same as a 396 cu in( imperial)

[@MattJonesYT]

Bizarre that this very day was the first time I was seriously considering buying a bore gauge because I am rebuilding my first small engine.

[@Shoptoolreviews]

Excellent time to have a bore gauge. Take your time and enjoy the process. It's addictive. Thanks for watching.

[@jamesgreen1614]

Calipers were just as accurate, some people know so much and end up not knowing nothing, calipers did prove you don't know as much as you think

[@user-ym1sc8pb2u]

Personally I would have used a micrometer as to me they are more reliable, calipers to me are just really good gueses.

[@stans5270]

Since you're using these, some people might like to know how to check for piston cylinder runout.

[@Shoptoolreviews]

Yes, you make a great reference. To do this, you would need to make several measurements around the bore. Truly, the right tool would a dial bore gauge that has the dial built onto the gauge. This allows you to turn the gauge around in the cylinder and watch the needle move. Definitely something we'll cover in a future video. As always, thanks for watching.

You showed me a useful way of doing things with a new tool now let me show you how to properly mow with a zero turn. One hand washes the other.
