Thanks. Have you done any inspection of the HT parts before and after? I'd be curious to know if the heated parts still retain their shape and size.
If the part has a hole, I imagine that you can use pin gages. Thank you for sharing your process.
I can't give an exact answer but I have made some tapping guide blocks that had 7 holes drilled for various size taps that I used the same heat and quench method on (but I left them full hard like a drill bushing) with no distortion-- Jack
