Buffing Granite Edges?

[pmarcusm]

Hey Guys,

My wife keeps snagging her clothes on the some of the granite counter tops in the house and I want to buff them using my RO90 and wanted to get some ideas and opinions of what to use in the Festool line that would smooth these spots out. I feel that a light buffing would solve the problem and make the wife happy!

Some Diamant should do the trick.

Fein sells silicon carbide discs and triangles that are made for stone and glass work  (cpofein.com/fein-63806129067-multimaster-stone-sanding-sheet-set)  The tris and  4 1/2" discs are available separately and work very well.

Platin works for glass as well. I haven't tried it on granite. It's abrasive is silicon carbide.

I also should have asked the question about which pad I need on the RO90 as well. Do I need a different pad other than what comes stock on the sander? and also any type of compounds or just the Diamant pads alone?

Thanks for the answers

The pad that comes with the RO 90 is the Soft Pad. It has some give to it but not as much as the Super-Soft Pad. For even more give, the Interface Pad is great and two is even softer.

Do you want flat or conformity?

Marcus, I would reconsider if I were you. Most granite guys would prefer to do a repair with epoxy, and that will require rough unsanded edges for a good bond. Also, they use diamond pads with a wet grinder for proper polishing. I don't know if that helps, but a buddy who does granite set me straight not long ago.

The RAS is more like the ones the granite guys use it spins faster. The pads are diamond and silicone I use them for polishing marble and travertine.

Stupid question, but is there a super soft pad for the RO 90? I've been using interface pads, but to get inside bowls I've been struggling to get the sander to go around the bend as it were. Also need to add some depth to it too.

I don't know about Europe but here, we don't have a super soft pad for the RO 90.

Same here then. Sorry, I thought I was going mad when I read what you'd written about the super soft pad, didn't twig you meant on the other sanders  [embarassed]

I just reread what I wrote and it was deceptive, though not intentionally...

No problem, figured it out. And without meaning to high jack the thread entirely, how high is too high stacking interface pads to clear a bowl's edges do you think? And is making a plywood "stilt" with glued on velcro bad practice?

 

[tbellemare]

I've stacked two interface pads on the RO 90 and it worked fine. I haven't tried more.

I don't understand you stilt???

I don't understand you stilt???

To gain some height between the body of the RO 90 and the sanding edge I was considering the possibility of a solid plywood "interface pad" to allow me to get right into the bottom of a bowl.

I stacked a couple of interface pads but you don't really get as much abrasiveness from even a 40 grit when used on stacked pads as I am sure you understand. I'm trying to clean up the bottom of a bowl made using a router bit.

Is the body of the tool getting in the way so you can't get in deep enough?

Exactly that yes.

There are definitely a few members who are doing and/or teaching solid surface techniques that are heavy on Festool usage. Hopefully one or more will chime in.

I haven't done what you're talking about but it seems that with a combination of the delta pad and round pad, you could get in there, at least, somewhat...

I'll start a new thread. Soz OP.
