- This is the 5th video in the "Old York Cornet Restoration Project" series. In this video Art patches the holes in the bell and solders the bell onto the valve section.
Here is the link to the playlist where you can see all of the videos about the restoration of this old York cornet:

The letter you got asking to restore difficult projects was right on. Glad you take on the challenge of repairing this instrument, really shows your craftsmanship!
I cannot stop watching your videos, I'm totally hooked. As a long time brass player I find all of this and other repairs which you do most interesting. Thank you so much for posting them. 👍👍
amazing series of videos of that cornet!!!
That is really amazing how you fixed that damage!
Once Again this is an extremely fun serious to watch, and including the Certian times of struggle when patching the bell's cracked section really showed a bit of the effort needed to Repair an instrument in such a way, looking forward to the end when its finally a put together instrument!
Great series! Watching intently, with much anticipation for the finished product. Thanks for posting!!!
Very interesting and well explained. Also the use of the camera is very illustrating. Thank you for these videos.
Thank you for these. You’ve convinced me of two things: 1) My horn is repairable 2) I need to have a pro do it.
Loving this series, thanks so much!!! Great work!
So much to be done while disassembled, more efficiently.
This is a very interesting series, thank you for making it.
I think perhaps you may not do much silver soldering. There is a trick to knowing when the metal is hot enough. As you heat the metal and flux, the flux will first dry out and take on a powdery appearance. As the heat increases, the flux will melt and flow, taking on a liquid watery appearance. This is when the metal is hot enough. A quick touch of the solder, which can be done after removing the flame, and it will be pulled into the joint by capillary action and flash around the joint, just as happened with your soft solder joints. You can tell that the metal was not hot enough because you got a bead of metal and it did not flash into the joint.
Usually when silver soldering you try to limit the flux area to the area to be soldered. The solder will not adhere where there is not flux. Of course in this instance you had a valid reason to use a much larger flux area.
Good info! Did he reach the correct temperature at any point of the video for silver soldering or was he a bit under temp. for those three silver solder points?
It's best to use lead-free solder on silver plated instruments (96-4 or 94-6) because any of it that shows will blend with the silver plate instead of getting that dull gray that regular lead based solder gets. It takes a little higher temperature to melt, but it's totally workable.
good job teacher
It would be neat to have a skilled cornetist come demonstrate the instrument when it's finished.
sorry to be offtopic but does someone know a method to get back into an Instagram account..?
I stupidly forgot my account password. I love any tricks you can give me.
@Armani Zayne instablaster :)
@Chase Leonel I really appreciate your reply. I got to the site thru google and im waiting for the hacking stuff atm.
Takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Chase Leonel it did the trick and I finally got access to my account again. I'm so happy!
Thank you so much, you saved my ass :D
@Armani Zayne Glad I could help :)
Thanks
This is amazing, and I really enjoy your videos. One thing struck me on this one:
It looks like your left eye got punched. Are you ok? You come across as the last person to get into a fight. You're so calm and rational.
No, I did not get into a fight. Because I have such light skin, my eyes appear very dark. Also, I was probably tired.
@@TheBrassandWoodwindShop ah ok. It just seemed so unusual. In a later video I saw it as well, so I figured it might just be natural.
Good to know that you didn't get into a fight. Watching you take out some of those tuning slides, though, it wouldn't surprise me if one flew back at you. Then again... You know full well how to avoid that. Me? Not so much...
Very nice! I have an old Wurlitzer cornet that has cracks, now I have an idea how to repair them if I ever get around to it. Mine is raw brass, I wonder if brazing would be more appropriate (or possible)
Great video! There aren't many good videos like this. Any chance that a ferrul would work for the cracks?
Yes
I am wondering if instead of the files to get into the small/thin cracks, would a Dremel steel brush bit be a good alternative?
That might work too.
Hi congratulations on your videos, your work is excellent. Could you tell me the name of the fux? best regards
Is there a special type of making used when soldering?
I thought that the flame could have been smaller. If you are using MAPP gas with Oxygen, you can get concentrated heat on a smaller area. I have found in soldering Cu and brass that works extremely well -- maybe not with silver though. Thoughts?
I have only used acetylene so I do not know much about other kinds of gases. Maybe I can try to experiment with them some time.
@@TheBrassandWoodwindShop Mapp gas is actually propane principally. By adjusting the propane and oxygen you can have tremendous control over heat and flame size. Mind you, I have not repaired instruments.
Why wasn’t the instrument cleaned before repairs began? It seems most of the basic necessary processes were skipped.
I will thoroughly clean it in video #7. I could have done it sooner, but I want to get the work done first since the work will mess up the finish.
What is the name of the liquid flux..is the powder flux more effective than the liquid flux..if I use butane flame can it melt it..to stick the broken thing I have to clean the surface so that it becomes copper or I continue to make connections..before I have make a connection but not successful..because it does not stick perfectly ..

I have never use powder flux, so I am not sure. Butane will take a little longer to heat up, but it will work. You can solder on silver, copper or brass.
I hope this helps.
@@TheBrassandWoodwindShop can i buy from you liquid flux..how much price liqiud flux at your place
i from malaysia..and i working in brassband army at my country.
It's not obvious to me why the bell gets silver soldered. It doesn't need the strength, and those cracks aren't joints which may creep over time. All I can think is that the silver crack repairs won't remelt when the valves are soldered on with soft solder.
Did you use acetylene or propane?
I use an acetylene torch for soldering and I use butane in the Micro Torch.
