Has he done the bearings right?

OK, it sounds then like cup and cone. The gritty feel could be three things:

1) The bearing is too tight (the cone's adjustment is too tight)
2) The bearing balls, bearing races or cone could be pitted and damaged.
3) What you feel is simply the ratchet in the freehub doing its job.

I suggest you remove the wheel and turn the axle by hand. What do you feel? Then, spin the wheel in your hand as you hold onto the skewer (you can do this with one hand once the wheel spins) and put your finger on the freewheel. Is there a difference before and after you've stopped the freewheel?

I'll have a go at that tomorrow. Will it cause damage if i ride the bike as it is?

If you have the tools, then we can guide you through it. I did it with Maz a few years ago.

I remember that thread!

If it is very tight, yes.
