[One step at a time]

Thin ones for cutting 1mm thick.
To smooth down welds ect use normal grinding discs or flappy one, I'll find s link for these as I'm not sure what there proper name.
Edit.
Just checked and there called flap discs.

As above 1mm for cutting. Try and get the thinner grinding discs (sometimes thick cutting discs) as these are easier to control than the thick ones.

Like above, I was using 1mm to slitting/cutting. It avoids wasting too much material if you have to butt weld them together.

 

I was using 3mm disks to grind for more accurate grinding- such as lopping the top off welds (even though some places list 3mm as a cutting disk) Some times the disks dont last too long when the fiberious binding strands become visible.

 

I used 6mm disks for removing bigger chunks of weld etc, going down to 3mm to ensure I didnt attack the surrounding panels.

 

I used flap disks for finishing, smoothing the weld over.

 

Also I use a black and decker power file for where access is tight, its easier than a file!

[castafiore]

The thin power files are excellent. The B and D ones are about £40, though Aldi occasionally do them for £30. Good for final dressing down of welds or rust removal in tight places. Get the belts from eBay.

I use something like these for all cutting

And these for grinding welds flat

And theses for heavier weldshttp://www.ebay.co.u...=item58a771a43c

Personally getting into tight corners I use a high speed air die grinder with carbide burrs.

Anymore info look at this pinned thread

P36 grinding discs are fine for all round use.

I have always found it to be good sense to buy a good make of consumable . I have had cheap flap discs that have the flaps glued on with a big splodge of glue in one area , meaning they vibrate really badly  and wear out quick . I have used 3M stuff and some other make which i cant remember for 1mm discs , something like Klingspoor .

 

 I prefer flap wheels to a hard grinding disc as most people gouge great lumps ot of things with solid discs , and they are bloody noisy !

I got some really cheap 60 & 80 grit flap wheels from Poundstretcher a few months ago. I thought they'd be rubbish but they're actually very good, cut well and dont wear too quickly.

Don't forget a good quality pair of ear defenders and strong goggles.

[mini93]

Just to re-enforce that... goggles, not safety glasses. and ensure they fit well!

I was using poor fitting goggles and managed to take a fleck of metal to the eye after it bypassed the seal up against my nose. Trip to hospital and a needle stuck in the eye to retrieve the foregn object and away I went.

New goggles were bought before stepping foot back into the garage!

I wouldn't risk the cheap one's from places like pound shops personally. I've had more than one budget brand disc disintegrate whilst in use, sending sharp broken shards of disc flying in all directions. Trust me, even if you're wearing decent safety goggles, the last thing you want is something spinning at 10,000 rpm to start disintegrating inches from your face!

Screwfix sell quality branded discs at really quite competitive prices, so for a couple of extra quid it's really not worth sacrificing your safety.

[Bubblebobble]

I am a baby and wear slim goggles and a face visor . Ive had many discs explode when some idiot has put pressure on it sideways - cue bits in your face .

Use the cutting and grinding discs manufactured by " Klingspor ", the best quality products around and the technical help is first class.

[myredmini]

I cant recommend uvex safety goggles enough! Seal well around your eyes, vetiliated and very comfortable. Can pick them up on ebay for less than £10 well worth every penny! Trust me.
