How not to use a digital caliper.

Cheap callipers have many errors not just measurement inaccuracies. For fine engineering work Mitutoyo 500 173 is grande for me. Enough for watch making. Lidl and Aldi callipers - avoid!

Yes, I like Mitutoyo calipers. I calibrate a few twice a year.

Is it yours Bill? Interesting to see it up for sale so soon after the recent thread on Tiger Cues.

No sir. I'm an engineer in a Metrology lab, , so would be shot for measuring anything like that. .

Missed that. I measure across the diameter from the side but I know the ferrule will get a little smaller as it gets near the tip if there's been a few tip replacements on the cue (usually anyway).

But I can see a gap on the left side of your photo. As tip size is what you're looking for wouldn't it be best to measure just under the tip?

That's why it's titled how NOT to use a digital caliper. Pic is from the linked ebay advert. .

Best to measure across the diameter , rather than holding the caliper slightly in front of one side.

and try to get the measuring faces parallel to the centerline of the cue/ferrule.
