Cylinder Bore Gages
Cylinder Bore Gages are a very popular and accurate way to measure a cylinder bore. The gage itself has a very large range of measurement but the actual travel of a cylinder bore gage is relatively small. This type of gage requires a master if you are doing absolute measurements so a ring gage or setting master holder is commonly used. Because the cylinder bore gauge is a 2 point measurement system it is perfect for checking ovality of bores.
