It is all in the disks...yet another new guy question

[hohenfelsjoe]

So, this is what I am thinking:

12" steel with the long shaft = Adhesive aluminum 150 grit sandpaper disk for sharpening

12" steel with the short shaft = Velcro kit for the rest of my sanding needs

10" aluminum = future use, may be with a 10-ER If acquired?

What do you think?

The 10" one is possibly a more useful one than to wait to use it with a 10e/r. I believe it is a Mark VII disk. Getting paper for the conical side may be a problem. The flat side is quite usable and MAY be more suitable for 'sharpening'.(if proper paper is obtained)

It is Not the same as a 10" model 10e/r disk.(if indeed there was one???) Methinks the smaller one was 9"(Not at all sure of that).

I've been reading the posts regarding sanding disks for 500/510/520 machines. If I understood correctly, Reible indicated he had to buy several hubs to "update" his 500 disks to 510/520 requirements. I have a 500 to which I've made successive upgrades -- for all except the sanding aspects. For whatever reason, I was of the belief that the 500 disks could not be used on the upgraded machines. I believe that came from Shopsmith. Are you saying there are conversion hubs available? If so, where can I get them? I've got 3 12" aluminum disks and would love to get them back in service.
Sincerely appreciate any info.

Hi,

The steel disks have a hub attached by 4 fasteners. You simply take out the 4 then replace the hub with the longer (shorter to go from 510 to 500) one and replace the screws (new screws).

The AL hubs are not made that way so far as I know so you don't have that option.

Thanks for clarifying. I'll stop scratching my head trying to make the aluminum ones work and get back to making sawdust.
One other question... any opinion on the pressure sensitive vs. the velcro discs? My experience attaching the old garnet sheets to the aluminum discs (use of adhesive, etc) was painful. I use both velcro and pressure sensitive with my portable sanding equipment and there are pluses and minuses with each.
Again.. thanks. Great forum.

The reason for the hub length difference is to allow using them 'through' the center of the table with the lower saw guard as a dust collector. If using them from off the side of the table without a guard, the aluminum ones do as they always did. PSA/velcro - a matter of preference except the velcro is not suitable for sharpening.

phillyfella, Welcome to the forum. Maybe this thread will answer some of your questions about sanding discs. It wanders a bit, but has a lot of info.
By the way, the longer hubs for your steel discs are available from Shopsmith.

With my 500, I use the velcro system with my aluminum disc and the pressure sensitive paper on a steel disc. Like you say, each system has it's own + & -. John McCrossen
