Among a few other things, I decided I should clean the saw blades before starting the self-study lessons, there was a bit of pitch on the teeth of all three of my blades. After dismounting the blades, I noticed that the arbors on the rip-cut blade and the combination blade are the same. The arbor that had the plywood blade is a bit shorter, perhaps that is just what the previous owner had on hand. Can't imagine that the plywood blade would need a special arbor.

The Arbor in the center on the plywood blade is the shorter Mark 5 with the original Table System aka Mark V 500 Arbor. The other two are for the Mark V 510/505, 520, Mark 7 and 4 with the larger Table/Fence Systems. For reference the shorter 1-1/4" Arbor is part number 505511 and the longer 1-1/4" Arbor is part number 555130. The shorter Arbor cannot be used with the other Mark V (510/505, 520, M7 & 4) Models as it interferes with the Lower Saw Blade Guard. Using the longer Arbor with some of the Mark 5/V 500 Lower Saw Blade Guards also causes interference.

thanks for the heads up because I have the 510 with the updated saw guard. I'll be sure to not use the shorter arbor.
