    What would you recommend to cut up an exhaust manifold neatly ? My grinder is not tidy enough. Is there some sort of electric hacksaw or something. NOT an air saw, my comp wont run it, I've tried.

    I want to cut the pipes back on one of these, to modify it. M42 manifold2.jpg

    Recip saw but band saw would be preferable.

    I don't know if these are still made, Desoutter made this air recip saw that uses hacksaw blades. Its bang on for cutting in tight spots like the manifolds because you can if you want use a whole hacksaw blade and being air can operate at virtually any speed you like. Just need to be able to prop/support your hand against something solid.

    As brightspark said a 1mm slitting disc on a 4.5 inch grinder is going to do that perfectly. Neater and more controllable than a rip saw that’s for sure.
    However if for some reason you simply can’t get it in to where you need to be then use another tool. Please do not be tempted to remove the grinder guard. I’m not insulting your intelligence by saying that I’m just saying because for a ‘quick, one off’ job I’ve seen it done too many times.

    I would say your going to struggle to get a 4.5" grinder in the places you've marked. So recip saw is my vote!

    Take the manifold off and then use a slitting disc on a 4
    " grinder!

    correct and wrap a bit of masking tape around where you are going to cut as a guide for accuracy :confused:

    To be fair, Mike brewer being fed into a grinder is probably something I’d like to see

    I was in a Jacobs Engineering office recently and they are very "big"' on H&S to the extent that you have to watch a 10min induction video before you can go and sit in a room.
    Part of the sales bumf running on screens in reception (showing the stuff they do or are responsible for) had a 4.5 inch ginder being used without a guard.
    Just goes to show that most of the people that compile this publicity (and a lot of the H&S bods) don't have a clue what they are looking for.

    Maybe it was put in to see who picks up on it but I doubt it.
    I'm sure the receptionist would be delighted to engage with some smart arse every couple of hours.
    I might make it the subject of one of their mandatory "safety moments" we have to have before every meeting.

    Using a grinder with no guard is bad enough but using one with a slitting disc is madness because those things will have you down to the bone before you even realised it's touched. If I caught anyone on my crew using a grinder with no guard they would be out the door instantly.

    I use one every day, i am careful with 125mm slitting discs, with 115mm discs they are quite easy to control! I do not condone using a small grinder without the guard, it has bitten me a few times however i find it a bit more versatile in tight spaces...

    :vsad: This is the bit I don’t get,
    Why?? What job is so important that it makes you want to do it using dangerous equipment?
    Why not buy a more suitable tool and use it properly.
