Just wondered what you guys reccomend for cutting out metal in tight spaces?
Basically I need to weld a small patch on a rear inner wheel arch where it meets the sill. There's no way I'd get even a small grinder in there without causing damage to other areas and I don't think a dremmel type tool would be up to the job.

Chain drill a couple of holes and then use an air saw or pad saw
Alt if you have one use plasma cutter

If it can be fixed with a hammer, then it must be an electrical fault

You can get proper little cutting discs for dremels. That's what I'd try (but that's because I have a dremel and the discs).
Obviously takes longer than a conventional grinder/disc combo, but you can be more accurate with it if you have the flexible extension attached.
The discs I have came in an accessory set in a clear and orange case from amazon, only cost about 25 quid iirc.

how about a pic of what you are doing?
remember you will need to get in there to grind the welds afterwards

Basically it's low down at the front of the rear wheel, just in from the lip of the arch where it meets the sill/outer quarter panel. Due to the way the arch curves and the the arch lip I wouldn't be able to get a cutting disc in the space, I could of I held it flat to grind the welds down but not at the right angle to cut. Plus the patch needed is only a couple of inches across so a grinder would probably cut more than I wanted to. |

Sounds like a die grinder or dremel is your only real option. Maybe a combination of that and chain drilling.
To clean up hard to reach places I always find a power file or 50mm sanding discs on a 90degree die grinder come in very useful.
Its one of those things. You could buy every tool under the sun to make life easier sometimes.

No offence but don't touch knock off dremel tools with a barge pole. I tried to save money with some and every single tool either broke out flat out didn't work. For cutting discs get the speed click discs, good thing is they sell them in bnq if you're caught out. The discs arnt fast and they don't last long but they are very helpful for tricky spots or small cuts. Just remember let the dremel do the work, don't lean on it. |

The reinforced discs are fine as long as you let the tool do the work and don't try to force the cut. I would have suggested a Dremmel to sort out the problem the OP was having but they're very slow going and there are quicker option

Used those exact discs to cut off 4x m10 exhaust down pipe bolts last week, very limited access otherwise I would have used something with a bit more grunt, they worked great. As you say, not the fastest and don't lean on them but they did the job. Used a disc per bolt but they're dirt cheap. Have used the Dremel equivalents that were supplied with the Dremel set and they don't last any longer but cost 10x the price. I do agree though some of them are curse word, have had carbide grinding wheels that have lasted seconds or the little wire brushes just explode, but those cutting discs I linked to are decent. |

Sharpen a thin chisel, if it's sharp it cuts easily, you can bend the edges back after with mole grips. No chance of a fire either.

Hole saw and a die grinder. If the hole is going to be 1" or smaller, use a step drill.
Without a picture, I have no idea what is behind or how close.

I do use dremel alot in tight spaces, but sometimes you cant beat a good, thin, sharp chisel. You can seperate spot welded panels without much damage with a decent chisel too. |
