Through out the thread, the no.1 statement is "it dosnt need to be 100% flat"
I lapped it first with my DMT to get the majority flat and then finished with my glass plate that is much larger then the granite plate, and as noted on here, the glass plate by it self is more then flat enough to lapp a hone (as mentioned previously). The granite plate was noticeably out before lapping it now its, as far as i can tell 100% flat (or 99.9% flat)
I'm very OCD about everything i do and if its not 100% im not happy. I just cant see how it can be decided that its not flat now when no once has checked it after.
