Cutting a paving slab
Is it possible to trim down a 600x600 concrete paving slab along
2 sides with a 115mm diameter angle grinder? Just wondering if it's a complete waste of time even trying... -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

If it's a bit too thick or you get bored, after it scoring as deeply as you can be bothered, and supporting it under the the cut- line, a good whack on the offcut ought to crack the rest away neatly enough - apart from the top edge, the rest is all presumably going to be hidden anyway. |

I did it with a couple of bog standard stone cutting discs (I didn't fancy buggering up my diamond tile blade). IIRC I got about two thirds of the way through and snapped the slab over a length of wood. Easy if the offcuts are a reasonable size. |

I thought of molding one, but that doesn't look doable in 24 hours (unless I molded it in place, maybe). -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Running along a strip of timber helps keeps everything tidy. |

I thought of molding one, but that doesn't look doable in 24 hours (unless I molded it in place, maybe). Will it look odd with two edges cut, however neatly, and showing sliced-through aggregate particles, and two edges as-moulded? If all four edges are visible, I think I'd want to run a Stihl-saw down all four. -- Kevin Poole ****Use current date to reply (e.g. )**** |

Blimey, you must be made of money. 9" angle grinders are really cheap (try the Site one) and diamond disks (from Aldi of all places) ridiculously so. As a 9" grinder is handy for stone cutting generally, it's not unreasonable. |
