I use this method to measure the cylindrical wear of an internal combustion engine. It's extremely precise, but time consuming, versus the more popular dial bore gauge. However, I continue to apply this method, because it is the method I was taught, and feel most comfortable with.
@@machiningmoments but your anvil is flat. Wouldn't holding the telescoping gauge straight and taking a measurement with your outside mic be more accurate than wiggling the telescoping gauge while trying to mic it? Thats the part I can't grasp. When I take sizes on a bolt, I understand moving it because you want the widest point of the bolt. But the telescoping gauge's convex sides are the same size or smaller than the outside mic's anvil... why wiggle the mic feeling for a brush instead of just taking the size?
@atvmotocross38 Although I have heard telescoping gauges called snap gauges, it is not a snap gauge. Please Google snap gauges. Thanks for your comment.
You can but in my experience they are harder to use in that you have to "fish around" with it to find the widest point.And a lot of machinists use an outside mike on them to get the measurement because they don't trust the measurement on the inside mike. They are hard to get the hang of.I much prefer the telescoping gauges it the hole ill allow it. Over 6" of course it is inside mike time.
@@machiningmoments There is a new method that you can measure with internal dial bore gauge of course you need a setting ring to master your dial gauge.
