How to Use a Telescopic Bore Gauge

[@lesliet2916]

Very nicely explained! I had to figure out the rocking part on my own, but I found your video to show to a friend. by matching the feel of the t-gage in the bore being measured and the way it feels in the micrometer, you can get very precise measurements.

Thank you so much, greatly appreciated!

Excellent! You really explain that very well, Thank you!

[@MattsMetalworking]

You're very welcome!

I can't believe you typed the dialogue. great demonstration

[@MattsMetalworking]

Thank you!

Best video for explaining how to use this tool. Everyone always skips over some steps. Also when removing the gauge. Can you just tighten it more so the micrometer can be used to ratchet without having to worry about the plunger depressing.

[@MattsMetalworking]

Thank you so much for the kind words. And yes you can, the ratchet should be a very gentle tighten anyway.

Nice demo. The only thing I might change is to not lock the gage before putting it in as when it springs out when letting it go it could it the inside bore harder than it needs to. Just depress the plunger(s) when putting the tool inside the bore.

[@MattsMetalworking]

Thank you and great tip as well.

Matt, thanks for the video. I've never understood why you rock the tool after tightening it, it seems like if it's at an angle, by rocking it, it would read wider than it really is. What am I missing?

[@MattsMetalworking]

No problem, always happy to help. Think of it as a right angle triangle. When you have the bore gauge on an angle, it's wider than the bore, so that would be the longest line of the triangle. Once you angle it back in the opposite direction, and it'll go slightly past being a perpendicular line. The lock holds that inner dimension, so the plungers are forced into place to some extent.

That helps, thanks Matt
