Concrete fencing

With one of these...

You could hire a masonry cutter.

That doesn't make sense in todays tools cheapness as you can pick one up new for the price of hiring the cutter and still have it for future use.

Angle grinders can seriously mame or kill, be carefull!! - especially when you hit the reinforcing rods

I think you have to balance the time it will take to do a 12 inch cut through two-inch thick concrete with a £30 angle grinder from Machine Mart (plus another £20 for a diamond blade) compared with a heavy duty masonry cutter and suitable blade from a hire shop. It's a matter of judgement.

Me, I would drive to a building site or roadworks using those sorts of tools and give a tenner or so (depending on how much cutting is involved) to someone there to cut it for me while I waited..

You not only want the tool, you want the protective face mask, ear protectors, goggles, etc...

So what are you doing in a DIY group?

Knock up a mould with plywood and make your own. It surely doesn't need to be reinforced.

Summary of concrete cutting and non-cutting suggestions, with varying degrees of DIY, so far:

Another suggestion for a non-cutting option: contact a local fencing firm who should be able to supply a concrete slab cut down to the required size since your normal shop is unable to provide this service. It all depends on how much you want to DIY. In my experience concrete is extremely difficult to drill or cut unless you have the right tools such as a petrol driven masonry cutter with the correct blade. Good luck whatever you decide!
