how to remove layer of concrete from driveway

[cyberknight]

This was kind of machine we used to use (the tungsten wheels in this are a different arrangement but the same principle applies)

Two benefits...it grinds away loose material plus is gives a good clean key got any new material going on top

thats the kind of thing im leaning towards

These three tools should be sufficient. Hit it from the side (as if scraping wallpaper) like the poster above said.

These will give you better control than any machine.

trouble is i have arthritis in my hand , had to have it pinned last year .

don't bother with the percussion type tools then, I don't have anything particularly wrong with my hands (apart from being in my 60s) but these SDS type hammer drills and breakers knock the hell out of my hands now

wonder how that 'lawn mower' type machine works on uneven ground, if some wheels are on top of the stuff you want to remove, and others are on the level you are aiming for - what happens ? how does that work - looks good in the video but would it do what you want?

I know the type we used to use, the wheels were mounted on a commercial buffer style wheel that rotates so there is a large contact area...so it only takes off the top surface, the peaks. It wouldn't touch the lower surfaces until the peaks had gone.

No reason to think (with simple logic only so not guaranteed) the type in the video would be any different.
.
One thing...if your wrists are weak, these are not light machines, they're really quite heavy (or certainly were when we had them30 years ago) The good thing is, the one in the video propells itself with the action of the rotors.

Been thinking, what about moving?

If it's only thin skim, swing a sledge hammer at it, if it cracks, carry on. Shovel the surface away, sweep up.

I love the way the video explains the machine pulls away from you when in operation - be a bit frightening if it came towards you, it would more than make your eyes water if your toes went in, followed by your legs

"wheres Dave"
"he was using the concrete grinder earlier"
"and where's all that red gunge come from, its everywhere"

On the maintenance gang in a confectionery factory many years ago, we were tasked with cutting gaps in the concrete filling of some RSJs for new pipe clamps to be installed. In the room in question, the warm air was thick with a suspension of ultra fine sugar dust which quickly coated our sweaty hands and everything else in a sticky residue. This resulted in our hands sliding along the shafts of lump hammers & chisels for the duration of the job in hand.
Now that was interesting - !
