Quote: Its 8mm.. I want to test it when I get home to see if I need to grind the probe housing.. but at 8mm I dont think I will
I purchased mine w/ a 6mm diameter flat-face probe and was the smallest they offered. I contacted the vendor about buying a second at the same time, because I suspected I was going to have to hand-fit one of them to read the curved surface of a cylinder bore properly... and I was right.
I spent some time w/ 600-grit wet-or-dry profiling the face of the probe to have a concave surface that appeared to seat properly against the inside of my 4.375" tapered ring compressor.
