On this video, I end lapping my granite floor plate. It was, in my view, comparatively straightforward to realize a excessive diploma of accuracy with fundamental instruments each for measuring and lapping. The one excessive precision device that was used was a Clock gauge calibrated in microns purchased on-line very cheaply!. I used a forged iron floor plate that got here out of a skip (dumpster) as a lap and constructed my very own “Repeatometer” to measure it. I discovered that though considerably daunting, it was a lot simpler to lap within the granite plate than I believed it will be! Do not hesitate to do that at residence, however, I can’t be liable for any accidents derived from this video!
