    Is it possible to remove them?

    Had my Xeno Soprano Cornet on the sink ready to clean out, but had to go answer the phone, come back and i find a tiny micro dent with two parrallel 2mm length scratches and a tiny ding halfway between the bell and the valve casing, on the left hand side... gutted... and it was a family member that "moved" it on me :rolleyes:

    Its a tiny dent, and to most people they wouldnt mind, Its not "that" noticable but i notice it!! :biggrin: I had kept in pristine condition for 4 months and its the first thing I see with the cornet, and it will seriously affect the resale value (if i ever trade it in for a blackburn ;) ) but mostly as it really really bugs me!!! I took a solft cloth and that silver plating polish and its covered up the scratches to an extent, but made the dent appear a little more prominent :rolleyes:

    I asked a local repairer and he said he would cause more damage trying to fix it... but I was wondering if a specialist brass repair outfit would have any more luck. Being from Northern Ireland we arent blessed with a lot of brass repairmen (or bands for that matter!)

    Ive taken pics of it, but if i could find the cable id attach pics!

    This is what it sounds like to me -- your repair person is used to desoldering parts and fixing things that way. That does do damage.

    But some repair shop with a good set of dent balls could most likely get it out with little trouble. It will still leave a mark, which could be buffed out.

    Dent balls are not cheap and look something like this:

    And require a dent ball driver of some kind:

    Easy enough -- find the right size ball, hammer out the dent and extract the driver using the vise. Here is the problem. Dent balls can cost $175 a piece! You can imagine what a whole set would cost.

    www.votwtool.com makes some of the best tools for such things, but they come at a price.

    At the end of the day I think this is one for a good professional.

    brownrob, you are probably making someone's life hell in your family!

    but it was you that left your instrument lying about. No excuses for that . . . . .

    If its easily accessible you could have a go at rolling it out yourself its a lot easier than you think. I inherited a pile of junk cornets and trumpets from my daughters old school and found it quite easy to roll out minor dents in the bell just with a couple of wooden kitchen rolling pins. One in the inside one on the outside

    I assume you are talking about the rolling pin handles (pretty hard to put a full rolling pin in a cornet :rolleyes: )

    Actually, they would be shaped very close to the "barrel shaped" dent balls. Probably would work just find on cornets and trumpets. Probably not strong enough for a bigger instrument. Hence why they are made of steel or stainless steel.

    Oh of course, thats why Im not cross with them! :cool: It did teach me a good lesson about never leaving a £1200 cornet sit unattended (I was only gone 2 mins!) I had been very careful up to that, cornet in case any time it wasnt being played (even at rehearsals)

    Im hopefully going over to Scotland for a visit sometime, anyone know of any good repair shops in Edinburgh area, and how much fixing one dent would likely cost? Dont worry, Im paying for it not the family!!!
    Or should I just wait incase I get a brute of a dent in it before I get it fixed? :clap: :biggrin:

    Thanks for the help so far! I dont know if Im confident enough to have a go with 2 rolling pins, like i say, its about 6" down the bell

    In that sort of position, I've seen dents removed with a wooden snare drum stick. Mind, I don't think I'd be confident enough to have a go myself ...

    I can recommend The Wind Section in Edinburgh - http://www.thewindsection.com - just took my cornet in for a bit of a smarten up - a major dint in the bell and a few smaller 'micro' ones as well as a general service. It came back looking (almost) as good as new. It cost me about £60ish +VAT, but if you're only knocking one dint out I doubt it'd be that much.

    Hope that helps

    Brownrob,
    I don't know who you spoke to, but I would suggest you ask Dessie Graham to look at it, and if he reckons it is best left alone, I would leave it at that. I know it's a pain but it could have been worse - no-one was injured (I hope).

    Hehe nobody got hurt! Where does Dessie hang out? I was talking to Mike Reynolds in Omagh, but he said he couldnt help me with it, but he isnt really a brass specialist, which is fine!

    Oh pass on my congrats to your Euph who played Delilah at the Valley Contest, was it Alan Haworth? Fantastic performance it was. Great opening too! :tup I only wish I was near that standard, I was helping Church Hill to 1st = in Grade 5 on sop that day! :cool:

    Thanks thats cool! I was over in Edinburgh for 3 years (2001-2004) and I never knew there was a Brass Band in the uni :( I just got about 10 mins a day, warm up in the flat in Marchmount, then them downstairs started beating the ceiling with the broom handle! :clap:

    Ahh, it only started the year after you left - shame! We're quite a young band, but going strong so far!

    Many thanks for your comments. I will pass them on to Alan. He is a great player. I will PM you Dessie's contact details.
    Best wishes,

    Dents & Dings

    Hi Brownrob,

    I read with interest about your misfortune of getting a ding in the surface of your cornet. If I was nearer to your location I could repair the damage quickly and permanently, as by profession I am a photogravure printing cylinder revisionist. This probably doesn't mean anything to you, but the few of us who can do this kind of work employ the technique of Brush Plating to eradicate small damages etc in the surface of Gravure cylinder printing surfaces so that they can be printed from again without having to be returned to the maker for expensive repair work. This technique is also used in specialist metal finishing workshops.
    The idea is that the damaged surface is initially cleaned and manually improved, as far as is safely possible, and then the actual dent, scratch or damage is filled to the surface with copper. This is a galvanic process whereby the damage, after filling, is finally surface-plated with similar metal to the instrument itself, i.e. silver or brass, so that is matches the rest of the instrument's surface colour, thus, after final polishing, produces a permanent and totally invisible repair.
    I would love to be able to help you but there's a load of country and some water separating us, but if you can find someone in your location who does Brush Plating, in the way I have described, then they should be able to fill any minor dent or scratch, and return the instrument to its original condition. I hope that this will be possible for you.

    Kind Regards, Malcolm McBride
