disc sander disc sourcing problem

[Platonic Solid]

I'm sanding the 100 year old rat shack exterior (thread link in sig) to get rid of lose paint before repainting. I'm using a buffer/sander I purchased some time ago and it works very well (Craftsman model 315.115031). It weighs 6lbs. The longer handle gives me good control.

​

One of the reasons I purchased it was I had a fair amount of 6" sanding discs from my really old all cast metal Craftsman disc sander (I was starting to feel current tingling through my arms during use on that one).

So now I'm looking for more 6" sanding discs and finding that they don't exist - at least not the ones with holes in the middle. I only find the adhesive backed (which I don't think I can use on the existing pad). Here are the discs I have been using.

​

I considered changing the pad to a 7", but the arbor is 1/2-20 thread as opposed to the standard 5/8-11. I actually found an adaptor to change that (link), but am starting to think I'd be better off just buying a new disc sander. I don't want to end up with an unbalanced pad.

So now I'm looking at new disc sanders (which is really annoying when the one I have is fine). I start looking at 7" sanders like the Makita GV7000C (link) which you can get discs for, but ironically only 1 grit actually in stock at HD . OK, I guess 5" is the way to go since those discs seem to be everywhere - something like the 4.8lb. Dewalt DWE6401DS (link). I know I want the pistol grip or I'll end up twisting my wrist off. I don't think I'd like to one speed Makita GV5010 (link) though the lite 2.6lb. is impressive.

Thoughts and guidance appreciated.

A picture of what sandpaper disc you have would be helpful.

how does the sandpaper currently fasten to the sander?

The second picture shows the threaded bushing in the center which holds the sand paper.

Here, I removed the sand paper.

Thanks for trying Cobbler, but those are too big at 6 3/4".

I've never seen a 6" angle grinder before.

Would 6" adhesive paper work? that's very common. They typically stick to a vinyl faced foam pad, maybe you could contact cement on 1/8" foam and vinyl to the existing pad.

That will be less aggressive than a fiber disc though.

I have the Makita PV7001C 7" Vertical Polisher. I put a disc adaptor from 3M on it so I can take any of their 7 inch discs in any grit they make from 24 to 120 grit.

Light weight with awesome control.

I had a Dayton Vertical prior to the Makita and just plain wore it out and replacement parts were nonexistent last time I rebuilt it. The Makita is the closest thing I have found to date that comes close to the Dayton.

You can see it in the back ground in this pic. I'll get a better pic of it tonight and the PN for the adaptor.

I have ran the snot out of this thing for over 10 years now. I even bought a spare. Sits on the shelf in the backroom new in the box.

Norton still makes 6" discs, you would need to make your own slits tho...

 

[joe_padavano]

Just use 7" disks. I've done this a lot. Yeah, they overhang the pad by half an inch. That's not the end of the world. Alternately, buy a 7" pad.

Benchmark Abrasives is where I would check.

Thanks for the responses. I emailed Norton, but they didn't get back to me. Went to the shed this afternoon to sand some more and the few discs I had left kept tearing so I headed for HD and picked up the Dewalt DWE6401DS cause it's variable speed and they have a healthy stock of 5" hook & loop disks. If they had any stock in 7" discs I would have gone with the Makita. I've never used hook & loop before, but after using it on the right half of below pictured wall I'm sold. It's a much better system than lose paper held by a center nut. The weight difference between the 4.8lb Dewalt vs 6lb Craftsman was noticeable.

This is a start. I'll leave this link here while I go search for a backing pad.

Put a pic up of the new Grinder with the Disc assembly up. I'd like to see it. I am always looking for new Grinding Technology.
