    Hi, I came across a 514 Range at the local scrap metal yard which was in pretty good condition considering. With all original parts accounted for (except for the four mounting screws and one flame spreader). I down played the situation by disguising my excitement (not knowing at that stage exactly what I had found) and brought it quick smart. This model doesn't have a badge like to 516, instead the name and details are stamped/etched in the range. I started doing a weak citric acid bath to remove the surface rust and galvanic corrosion but needs a stronger mixture, if I do this I'm worried I will lose the detailing. I plan on painting this black again so may lose it anyway. Your experience and opinions will be much appreciated

    Photygraphs! We need photygraphs.

    Without some photygraphs you'll have stovies right around the globe snarling and growling at you, calling your character and lineage into question, muttering ancient Nordic curses into their beards. Now we don't really want that then do we? You wouldn't want trolls bashing about in your kitchen late at night, would you? I thought not.

    Photo's. First one is before the bath. The two after that is after the light citric acid bath. And the last one was as I found it. Unfortunately not long after getting it home I noticed a crack in one of the tanks underneath. So will only be firing on one cylinder until I get this fixed if do-able

    Here’s a few more of its current state, also broken is the pressure relief screw. These ones have primus on both sides as opposed to primus and Sweden

    Looks like a nice project to me! Strip it down repair the tank, new air screw, washers and flame spreader and away you go! If only it was that easy but it should not be too bad. The design is very simple and easy to get back to components for restoration one step at a time.

    I would not use the citric acid on the steel parts.

    How big is the split in the tank? Braze or solder repair or maybe a patch depending on the exact details of the damage. Judging by the filler caps it could be quite old and it would be great to get her running again.

    good luck post photos of your progress and I am sure people will respond.

    Cheers, Nick

    Thanks Nick,
    Yeah, bit of fun to have. the split in the tank is about 100 mm long. I'll investigate getting it repaired. I have a few old Primus #5 tanks that I experiment different things on so going to try my hand at some brazing. Most definitely will post up progress photos.

    You should be OK with a soft solder patch rather than a brazed one. there are several threads on a similar subject one of which was quite recent but I cannot remember who posted it. No doubt others will chip in if they think you are going down a difficult route.

    Is the split on the seam or in the main body of the tank?

    Cheers Nick

    Some updates:

    Did numerous dips in the Citrus solution.
    Dip, clean, brush, dip again etc, came up pretty good. There was a lot of pitting. Then a couple of coats with heat resistant paint. However it is scratching off in places so I think it will need to be re-done with a primer.

    One tank has a 65 mm crack, this is the repair I’m thinking about how best to carry out. Possible soft solder, but would like it to retain brass color

    The tanks had a lot of corrosion, polishing has been a mission, I am liking the look of the semi polished tanks that still has some patina. I'm thinking of only going this far instead of a full polish. Any thoughts or advice is most welcome.

    G,,day. personal choice whether to highly polish or not but the downside of highly polishing the tanks is that you will be removing a fair bit of brass to get a really good finish. this must weaken the tanks, you already have one crack. is it worth the risk ?? also patina = character = appeal , my likes :)

    just my thoughts.
    cheers
