Older machines had the AL disks with the ribs on the back. At some point they went to the steel disk like is being used now. The machine I got in 1976 came with the steel disk so it happened sometime before that.

The steel disk has an arbor that holds the disk part on with 4 screws. The version that is the AL one that you are picturing is a single piece and there is no option that I know of to make it work with the newer 510 guard.

I'm not sure how you ended up with the AL one but yes it can be used without the guard or on the other side of the headstock were there is no provision for a dust collector.

A fair number of us decided long ago that it was far easier to own a set of these steel disks and mount fine paper on one, medium paper on another and course paper on yet another one. If you do sharpening then another with iron oxide paper. The you might want another with velcro that will allow easy paper changes but can give you a more rounded edge when sanding..... so you might in the future find that a couple more sanding disks will be handy.

The issue come when using the lower guard/dust port. Once that is mounted then the 500 version stuff no longer works correctly. If you don't use the dust port then they fit fine. Once you start sanding with them you might be surprised at how much dust they kick up.

The AL version will not work with the guard/dust port mounted but you can use it on the other side of the headstock.......... if you want.

I think I just had the lightbulb come on. I watched Doug Reid's video and he has a different disk. I see what you're saying. This arbor is meant for a later model sanding disk that is plastic. Mine does not need one and will fit on the quill normally just without dust collection. Correct?

Thanks Ed. That's a big help.

I wasn't aware that the table upgrade would change the arbor required. Is that in fact the case? If so, it looks like I may be waiting another few weeks before I can use this thing as I ship it back and wait on a new one.

No need to wait (at least not for want of a proper saw arbor). I see at least one and maybe three among the items shown in your photos. The very last image appears to be a 510/520 arbor that is still packaged.

Congratulations. You made a good haul.

Left to right,
- A set of stacking dado blades and chippers.
- A dado blade, the "wobble" type. As the blade turns it rocks from side to side to cut the dado, the amount of deflection is adjustable,
- A plywood blade, lots of small teeth to get clean cuts on plywood.
