Steel vs Aluminum sanding disc?

Are there any advantages of one or the other? Also, did the 510 discs have a longer mounting shaft?

Side note...just picked up a SS 510 complete and in great shape. Even had the telescoping legs. It will be my "go to" machine....and a SS dust collector. I am just giddy.

Hi and congrats on your find. Yes the sanding disc for the 510 does have a longer shaft or collar on the hub. Also the saw blade arbors have a similar longer hub. This is necessitated by the wider table so the saw blade lines up with the center of the table. Enjoy yourself safely.

Thanks! What do you know about aluminum vs steel sanding discs?

The aluminum one has vanes that kick up a lot of wind; the steel one is fairly wind-free on its own. Of course I always run the Dust Collector on mine.

Is that why they are built in? I figured it was for support in case the aluminum got hot to resist warping. I guess it would have to get real hot for that though.

thanks. I already have different ones that I was making a complete unit out of. This one though, wow. Not a speck of rust anywhere. No stained up tables, and has the legs. Woohoo. I got a lot of little stuff I had been looking for. Now I need the bigger casters. I plan to have a few machines setup for a home school shop class. My friend is a welder and another friend is a brick mason so that will be it. Woodshop, welding, masonry. Don't have any auto mechanics. I'll also be facilitating health sciences and math since I am an RN. Should be fun.

Oh I'd suspect you're right, cast aluminum would need some buttressing. I think the 'windage' is just a side-effect....
