How hard is it to cut 25mm granite paving on a table saw?
My wife has just seen a sample of granite paving! I may not be able to get away with the easy option of using block paving…
One issue with using granite paving is that I will have a lot of cuts to make, so how long does it take to make a cut on a table saw. (All the cuts will be at right angles)
Am I right to assume that table saws have an adjustable guild to make it easy to cut strips? (Like a wood table saw has)

In theory it should be fine although any long edge cuts may be an issue. A Stihlsaw and diamond blade would be a better option though it's easier to use and isn't a 2-3 man lift like the table saw.

you need a top quality blade,PPE and training
effectively you needs street or stonemason

A good blade is the key. Granite is bullet proof, so you will need to use water suppression. If you can get a decent sized table saw then it will make it easier to get straight cuts

Is it really a two person lift to cut a 300mm x 600mm x 25mm granite paving on a bench saw?

Pablo seems to think that a table saw always needs 2 or 3 people for some reason, hopefully he will explain way.

A sthil saw is the best option but you need a steady hand and practice if your cutting expensive granite read the cutting page a few times and practice on some old slab until you feel confident or cut straight,stand over your slab,be relaxed and make sure you can cut right through the slab with out have to readjust your stance, rev it up before you touch the stone and in one steady move mark your slab with the saw then return to the start of your line rev it up and look at the left side of the saw! start cutting keeping the blade angled at about 5 degrees away from your required piece and about a mill off your mark and cut through. make sure you use a water pump after you have marked your cut and all the ppe

The table saw not the flag is a 2 man lift you'll not be able to move it on your own or in a car the flag you can lift with one hand it's pretty feckin obvious what I was refering to.

Pablo, Sorry I never thought about the table saw being a two man lift as an issue. My local hire shop only charges £5 to deliver and collect and looking at images the saw seems to have wheel on two of their legs. I was assuming that there was some issues that meant it took two people to operate the table saw.
Cookiewales, I may be missing something, but I have had training in using a woodwork table saw. Apart from dust being more of an issue, what else make a stone table saw more risky then a large wood table saw? (I have not had any training in using a sthil saw)

you normaly have your hands alot closer to blade and there is a massive amount of water to contend with and stone if not held propley you need two hands on stone one foot on peddle to lower google stone cutting with clipper norton am sure you will be able to see what i mean can be a beast theres alot of vibration to contend with you may be better with still saw safer to learn on ps i dont and wont go near a wood table saw but have no problem with my fingers holding clay paviors both sides on cross cuts and i never wear gloves on the saw like to know where my fingers are 
good luck be safe out there

If I cut a 300mm slab in half in a table saw, how large will each half be, e.g. how wide is the cut?
When I was taught how to use a wood working table saw, it was common to make a custom wooden template to hold the work, so hands were a long way away from blades – why have I not see this in any write ups on stone table saws?
On a saw with a sliding deck, and a custom make template it should be possible with a few clumps not to touch anything apart from the end of the deck while the cut is being made. I think I can cover all the cuts I will need with 3 templates.
