Awesome man, proven that this method is probably as good as it gets, I’m new at these and your video was indispensable, thanks
Pleased to hear it mate :) lots of people
discredit them because they haven’t put the time in to get use to them, but when you do, they’ll be as accurate if not more so than a dial bore gauge which typically read to 0.01mm where as this set up reads to 0.001!
Your method is a little slower than what I do, though, the results are really excellent, good point mentionning the use of good quality gauges, I know by experience that cheap gauges aren't good for anything.
All in all, you understand quite well the principles of the whole process...
Good demonstration and excellent repeatability.
It does make a difference that you are using good quality kit.
I think using a dial gauge with a digital indicator is much faster once set and very repeatable. You are only really making one measurement, when you set it. You can of course use a 0.001mm gauge as well. 👍
Secondhand dial gauge sets come up regularly and aren’t too expensive.
Thanks for the kind words - Yes you’re right good tools make a big difference to accuracy and repeatability!! I also agree about the speed and efficiency (and repeatability) of a dial bore gauge! :)
2 things I don't fully understand:
1. How do you find centre so easily? Surely the gauge doesn't want to be perpendicular to the sides of the bore? The springs want to push out and skew the gauge?
2. Not quite sure what you mean when you pull back when tightening the nut at the bottom?
It will automatically search for the widest point. Pivoting the gauge in the bore encourages this.
When I say pull back when tightening the nut it helps maintain friction between the gauge and bore and stops it slipping off and affecting the accuracy of your measurement. It’s just light pressure.
I love the lingo across the Pond, Gudgeon Pin? We say Piston Pin or Wrist Pin. I’ll take a dial bore any day but there are errors using a micrometer to set up a dial bore versus a calibrated ring gage or dial bore setting fixture. Good vid Mate!
Well said mate! Both require accuracy and attention to detail. Thanks for watching and sharing your experience!
I use pretty much the same method as you and I find if I invest the time and effort as you have done they are indeed very accurate. Once the gauge is set in the bore I take the time to properly set the mic as you do. Having done that, if I need to be very precise, I return the gauge to the bore and 'feel' it in the bore then check the 'feel' back in the mic without changing the mic setting. If the feel is the same on both the I’m confident I have a accurate bore size. I’ve checked this method on occasion with slip gauges held in an internal bore holder and found it to be within a couple of microns every time.
Yep well done, same here. It takes skill and time, but it’s well within the accuracy of any dial bore gauge measurement!
i will be buying telescoping gauges based off of this video, thanks!
My pleasure :)
by far the best demonstration available to date, however u forgot to cover the mic markings, now some might tell u were cheating using them :)
@@VintageEngineRepairs correct:)
베어링 내부 공차는 - 값으로 만들어 지는데, +0.003 은 잘못된 측정입니다.
Hey :) I’m sorry I don’t understand
but a dial bore process is a one step .
Not in setup and often only gives you to the .01 of a millimetre.
