To use the original system (guard as pictured below, carriage lock aligning the blade to the table slots), you'll definitely prefer to use the original short arbors and 9" blades by Magna. Those blades come available frequently on Ebay and such for not much money, they're of high quality for their time and sharpen up well. I haven't seen any carbides, but having the standard blades sharpened is inexpensive too.
I assume by blade choice you mean a 9" diameter blade. Please explain how the diameter of the blade relates to the length of the arbor. :confused:

The blade diameter is more about the guard than the arbor per se. The original VII guard won't take a 10" blade, at least not comfortably.

OK, but that was not the point of the OP.

Mike,

The Sawdust Chute/Lower Blade Guard P/N 505705 for the Mark VII that Steve is talking about is the same one I showed a picture of (on it's box) in my previous post. Since it is not the one you have there is no worries about using 10" Saw Blades. The 505628 Lower Saw Blade Guard you have was made for use with 10" blades.
