porter_jamie Posted December 10, 2020 Report Share Posted December 10, 2020 sorry, i meant setting your waggle stick on a micrometer. its not great. setting ring much much better 1 Quote Link to comment Share on other sites More sharing options...

I think, as you've mentioned, you set it with a setting ring and then regularly cross check with it, even this sort of bore gauge can be very accurate. 1 Quote Link to comment Share on other sites More sharing options...
porter_jamie Posted December 10, 2020 Report Share Posted December 10, 2020 yes thats much better obviously. if you can't get exactly the same reading every single time in the setting thing, then you are wasting your time. 1 Quote Link to comment Share on other sites More sharing options...
gixerboy1 Posted December 11, 2020 Report Share Posted December 11, 2020 I reset all my mics after they have been calibrated. I do not use the ratchets or friction thimbles on them and have a different "feel" than the insoector that sets them. Complete waste of time having them calibrated really. 1 1 Quote Link to comment Share on other sites More sharing options...
eddie Posted December 19, 2020 Report Share Posted December 19, 2020 Nothing wrong with Moore and Wright tools, telescopic gauges would be a good alternative to using a bore gauge ( as long as you have a mic to measure them with) 1 Quote Link to comment Share on other sites More sharing options...

Little finger through the anvil. Thumb and forefinger on the thimble. Other hand holding the job and the lightest of touches so you can feel the difference between measuring and clamping. For those people that don't have this feel a mic is nothing more than a graduated adjustable spanner. 2 1 Quote Link to comment Share on other sites More sharing options...

Problem with this approach is when you have an inspection department that do use the thimbles, as ours does. Then your parts don't get through.

Yes, but theirs are calibrated using thimbles so we have ours done the same, saves any argument come inspection. Quote Link to comment Share on other sites More sharing options...
