Dressing beswick limestone slab.... - TilersForums.com

[Andy Allen]

Got some beswick tumbled limestone slabs to do in the new year, I have to cut a curve in some of them and dress the edge, was going to use a polishing pad from ATS what grit would you recommend for limestone.
Or anything else that I could attach to a grinder and use...

Silicon carbide #120 will give a honed finish.

If the edge is being seen and you don't want what appears to be a machine cut/finished edge then you could finish with silicon carbide brushes to give it more an aged appearance.

Can they be used with a grinder ?

Better used on a polisher or variable speed grinder.

You'd have no control at 10,000 rpm+.

I always explain to people that the clue is in the name - a grinder is great for grinding (and cutting) , if you want to polish you need a polisher.

As this is a one off job and I just need to dress 2 curves, would the hand polishing pads work ?

Or the multi tool pads...?

Ask Santa for a variable speed grinder!

Really it all depends what finish you want.

Wet and dry paper will work for a one off.

It's worth investing in a variable speed machine as it really opens up what you can offer the customer, I see a lot of guys on here use the Bosch one, which looks like good value for money for a few jobs.
