Surface plate 2 - 定盤 2

BB holder

I got this granite surface plate last weekend. I like this. In Japan, the frame builders use more iron surface plates, but I wanted a granite one, not iron one. Granite keeps a perfect flat plane in any condition.
Surface plate is a significant tool to check frame alignment. It is expensive, but I could get this one with a reasonable price. This is 2000 lbs with the stand...
