In reading posts it seems as though there are three kinds of runout. Following is what it looks like to me. I would appreciate any comments.
1. Plate runout; deviation in the plate as measured just below the bottom of the gullets. In industrial saws this may be from under 0.001” to 0.002”. In Big Box, consumer saws this is typically 0.004”
2. Blade runout: deviation in the blade as measured at the saw tips usually with an optical recognition device. In industrial saws this is usually from 0.0005” to 0.0015”. Typically specified as a nominal 0.002”
3. Machine runout: the total deviation of the blade mounted on the machine and includes any variations in the machine shaft, etc. 0.001” is good but it can be much higher than that.
