Hello,
Is it possible to calibrate a larger surface plate with a smaller one? I have a granite surface plate that is 640x400 mm that is flat. I found a larger cast iron surface plate that is 1000x700 that I'd like to buy but I'm not sure how to recalibrate it. I've always scraped from a larger master to a smaller, never the other way around. I considered using a small cast iron surface plate that is 400x400 mm to transfer from the known flat diabas plate to the new larger one, and then try and measure the high spots. I assume with enough overlap that the larger plate would eventually get flat but it feels like a brute way of doing it. Is there a proper way of doing it?
Best regards
