Yet more advice required from the experts!

As part of my patio project, I'd really like to create a curved free edge in Indian Sandstone up against a planted area + slate chippings.

However - its an INTERNAL curve in the edge of the paving I'm after.....so that the paving slightly 'wraps around' the planted area....

I have a 9 inch AG + diamond wheel which is OK for straight cuts and I can create external curves using a series of straight cuts around the radius.......

But its not an external curve I'm wanting.....

Its an internal curve.....

Although the curve will be very gentle I cant cut it using a disc.

Have any of you guys been tasked with cutting internal curves and if so - how did you tackle it?

OK..... I'll probably end up cutting a straight line.......

Thanks in advance......

4" grinder with a decent blade. Time consuming, dusty and fiddly, but the only way I have found possible

what dan said
if the curve is big enough you can do it with a 9 inch saw by leaning the saw over but it is only for the experienced really

Thats good advice...... thanks.

I've got the relevant equipment and know how to use it safely so may well have a go......

Favourite blades for this job, anyone?

Diamond, I expect?

Thanks

There are such things as curve-cutting blades....see last paragraph of this section of the Cutting Curves webpage

Thanks for your advice on this..... the internal curves will be quite gradual, so I reckon I'll have a go with the
4.5 inch AG and a diamond disc. The curve cutting blades look interesting but are a bit pricey for the amount of work I've got to do.

Thanks again. Much more confident now!
