I have several different types of bore gages around the shop, anything from Interapid, Mitutoyo, Fowler, you name it.
Ideally, the very best way to set these gages is with a ring gage. I have several different common sizes that I use to set my gages, but it's just not practical to buy a ring gage for every size that you may need to check.
I have a shop made holder that holds a gage block stack up between two ground fingers.
The holder has a lock and a fine adjust to tighten the stack up..........but I've had problems with this. It just doesn't seem to be 100% accurate all of the time. I have set a bore gage to the gage blocks and then checked a known ring gage size and resulted in .001 difference which is unacceptable.
What do you use to set your bore gages ???
Oh how I wish I had a set of Sunnen bore gages and their masters. The very best set up for measuring holes made, in my opinion.
