    What's the knack to cleaning up after you've welded, but where the angle grinder can't fit into the area?

    Learn to get a bit better, then it shouldnt need cleaning up!!

    Anti-Spatter sprays can make spatter removal very easy if used properly. Good if your welding into corners. Even on things like railings, just a quick rub with a wire brush and its all gone.

    Of if you have to grind a weld off, a die grinder with a burr cutter (not a stone) often gets into tight spaces nothing else will.

    Ha ha , give us a break. :) I'm restoring a 69 Triumph Spitfire and some of the repairs I've had to do, show on the outer body ( No matter how neat they are ) and I'm aiming on using as little filler as poss!

    I take it you are TIG welding? If you are using little filler, you really shouldnt need to tidy. It only reduces the strength of the weld, and some people, (like myself) quite like to see the weld, as you really see the craftsmanship over Chinese mould formed junk :)

    Appologies, Firstly, justme, sorry bud, just reading the reply I put with your quote. It makes no sense to me now, but I was a bit P****d off yesterday as earlier on in the afternoon some Tw*t in a white car/van had decided to run it upagainst the rear drivers side of our car. Did they stop and leave a note on the windscreen to apologise and leave the insurance details? Did they fcuk !!!!
    I'm calm again now, The reason I nedd to clean up the weld is I'm restoring the car and obviously where I'm cutting out rust and repairing panels, weld does show and you obviously can't have weld lines on the outside of your car can you? and some of the places are too tight for the angle grinder . But I took Hitachimad's advice and think I've got something suitable.

    I would use a die grinder. I have a small, right-angle one that I have various bits for. Basically the same a s an angle grinder, but has no shroud and will accept any 1/4" shaft wheel, stone or brush.

    Requires a compressor though. Have not seen electric ones.

    Fitting an angle grinder dicc that's a little worn can help sometimes. Fitting a new one can help other times. Failing all that I'm with the air grinder people - takes ages but air grinding is great for tight spots.

    For fiddly stuff I've always found a 4 inch angle grinder a lot more useful than a 4.5 inch grinder. Might just be me, but that extra half inch seems to make a lot of difference.

    You can get electric die grinders.
    Small routers that have removable base also doubles up. Like the little B&D ones.

    Malcolm, you're sounding like my wife saying 1/2"makes all the difference !!!
    Justme, yep, I was thinking that, but the small heads don't last long at all, but I think that will be the way to go. I nipped into my Fav place, Machine Mart to buy a reel of wire and also got a selection of Dremel and normal drill grinding bits so I'll see how it goes.
    I did look at the Air grinder route but I'm not sure my compressor has the guts to run it properly.

    AndyF, my 1/3 HP die grinder took about 1.5x what my 3.5HP/11Gal compressor would do. That meant I had about 30 seconds use before the pressure was too low. Then had to stop and wait for compressor to catch up.

    With my 5HP/20Gal compressor, I can run the grinder continuously and the compressor runs about 40% of the time. The new comp. is 9.3CFM @ 90 PSI. Old was 4.3CFM/90.

    There is the Rotozip here. Basically a big Dremel. Will accept 1/4" die grinder bits. My dad has one. They are nice, but a bit bulky.
