    Polishing gouges out of a bolt cocking shroud

    Iv got a brno with a bit of damage on the bolt cocking shroud from where someone has grabbed it with something like vicegrips to re-cock possibly when it was out of the rifle, It is the only let down on the metalwork of the rifle, and looks bloody unsightly.
    will wet and dry sand paper in the 200 range be a good place to start to polish these away?

    is the there a better way?

    Be good to have this rifle looking tops once again

    Probably/possibly not aggressive enough, and soft materials will flex over the area leading to that humped, light reflecting "Bubba's finest" look.

    Can you get hold of something rigid like a India stone set or the like? The rigid nature helps you control the amount of material removal.

    Once the areas are evenly smoothed, degrease and strip the blueing and then use a cold blue over the degreased and 'white' steel. I normally apply with a cotton bud, burnish with steel wool and reapply then leave to get a good rust going overnight. Burnish with steel wool/oil combo and degrease and oil. This differs from most cold blue instructions but it's the only way I've found to get the same sort of smooth look as factory blueing...

    Also, suggest tapping the rough areas with a small hammer to panel-beat the raised material back down - but this takes a LOT of finesse and care and time (multiple tiny taps only hitting the raised area maybe with a tiny punch?). The work will need to sit on something soft like a sandbag or the like so that the other side doesn't get a dent...

    Can be quite surprising what you can get back to looking good if you spend the time on it, but it is a LOT of fluffing around...

    thats a brilliant idea with tapping flat the ridges,

    while Im at it mauser, is it easy enough to bend the bolt back a bit for asthetics?

    Id start with 200 after tapping down high spots, if it looks too slow (deep guoges) go 100grit and work back up.
    Wrap strips of wet and dry around a file or Dowl to get it to "cut" flat like using a stone.

    Easy enough to bend if you have the right gear, need to be careful not too heat the body of the bolt so copper heat sink, heat stop paste. Could be one for a pro, cheaper than getting set up for one off jobs... I would farm this out for that reason.

    Bend blot handle I take it not the actual bolt?
    handell would take 3-4 seconds tro heat o red in one spot and bend with a decent torch, dont bother with one of those besine? heater/torches would take ages and the whole thing would have to heat up.

    The reason for the heat sinking is to protect the threads and cam and the like at the back of the bolt, could get away with a copper rod and a die of the right size if you can track one down. The secondary is not stuffing the finish or warping something or worst case, affecting the heat treatment of the lugs. The bolt handle often serves as a secondary 'safety lug' not sure in the case of your bolt off the top o ma head...

    Have a ganders online, see what the go is with the interweb exports and see what old timer gunsmithing books have to say on the subject.

    The other thing to consider is that sometimes its better to settle for minimising the damage than " over repairing " it . I would settle for tapping it down flush and leave it at that , if you stone and emery /wet and dry the damaged area you could wind up with a smooth shiny finish that might look even more out of place
