This time, M. Ito will show you how he polished, re-lacquered, and mirror-finished a trumpet. The trumpet is Nikkan Imperiale made around 1960’s. Nikkan was a Trumpet and instrument manufacturer merged by Yamaha in 1970.
As the valve casing and surrounding pipes were very rusty with the most of the lacquer has gone, most of the work has done on this area. On the contrary, the Capricorn bell formed a beautiful oxide layer, so I left it untouched.
The trumpet used has already been stripped of paint (delacer/unlacker) as explained in my previous video ( • Removing Lacquer from ... ), and has a bare metal surface.
How I polished it was very straight forward, applied compound on a cloth, polished and wiped off. I have repeated this process for about 5 hours until the trumpet gets shiny.
Then Re-Lacquered with an Acrylic Clear Lacquer Spray. First, wash off the oil and compound with a mild detergent, dry it thoroughly, and mask with the areas where lacquer is not needed before painting. When you spray the lacquer, it would be good to apply the very first spray only lightly in order to create a layer which will ease following sprays to stick on the surface without being repelled.
Final step is mirror finish, where bubbles and matte surface was polished off with #2000 sand paper and compound, as well as a Jewelry Polish Cloth giving the Trumpet shiny and elegant finish.
Be careful not to do this on lacquered or plated trumpet as this will only damage the coating if it is not applied on bare brass metal. It's a good idea to practice with a junk trumpet several times before doing it on your valuable horn.
thanks
thank you so much for making this video. have you also re-lacquered the bell? any special tips for that?
I didn't relacquer the bell as it was unlacquerd one and had beautiful copper dioxide surface. While lacquering the bell is nothing different from other parts, be careful not to paint too thick as it may change the sound, and too thin may leave some area uncovered and insufficient from protection. The good way would be painting thin layer multiple times until it is good enough. Also when you are not satisfied with it, you can unlacquer and repeat the process.
Also don't forget to put something deep inside of the bell so that lacquer doesn't go into where unnecessary.
@@vfd03445 thank you. really good advice
@@amphidory7600 Thank you for the comments. I hope it helped.
@@vfd03445 it has
Kinda thinking this was done in 70s according to the music background 🤔 bit it's amazing
Чешский "Фестиваль" срисовали с этой модели.., хорошая дудка была в своё время...
What compound are you using to remove the old lacquer?
I’m using compound around #4000. But in order to remove the lacquer, a chemical spray like paint remover works rather than compounds. Be careful also it does not work on plated Trumpets.
You mention using "compound" to make the trumpet shiny-- but you don't say what that compound is. Can you please describe? Is it a basic brass polishing compound?
Sorry for my delayed response. You are correct. It is a basic brass polishing compound.
A cotton buffing wheel is very inexpensive, and can be purchased with various grits of abrasive. Each grit needs a dedicated wheel of course. Brass wire wheels work well too, and do not scratch.
Cotton buffing sounds like relieving me from sore muscle! thanks!
@@vfd03445 elbow grease
I wish I had taken a course in speed reading so I wouldn't have to keep rewinding and pausing the video to read the text.😊
You would think you would have some sweet trumpet jazz music. Lol
Is the lacker is good for long time?
Thank you for your comment. Yes, lacquer nicely done will last for years. Spots where is left not covered with lacquer will discolored. Please refer to another video showing one year after the reacquiring. kzhead.info/sun/dadynNGpqJtohHA/bejne.html
Your text flashes on the screen so fast, it cannot be read in its entirety.
Thank you for the comment. I'll add the caption more readable next time. In the mean time, you can slow down the KZhead video by clicking the settings button on KZhead and select the playback speed, so that you can watch it as kind of a slow-mo.
How do u remove spray paint on trumpet ?plz answer
Bro what 💀
Do you have the reference of the lacker? Is lacquer hold well. is it strong?
I think this lacquer is only sold in Japan, but here is the link. Maybe, somethisng similar is available in your country. The product description says: Color: clear gloss Material: nitrocellulose, acrylic, organic solvent. www.amazon.co.jp/dp/B001BFZIM8
One year has passed since I did this. The surface is still good and shiny regardless of my daily use.
Would have been nice to see the bell....no where in the video you show the bell, yet mention "it has beautiful oxide layer" 1:34 . Would have been nice to see it, maybe it is in another video on your channel, I will go look. Otherwise, thanks for video.
Don't apologize for your legs. If you went in a tub with clothes on you'd be wacky😂
Does this method work on the inside on the trumpet too?
Yes. the workflow is the same, removing old lacquer, polishing and placing new lacquer. But, be careful not to put too much lacquer inside, as the puddle of lacquer could choke the pipe.
you did not fix the dents first???
Ideally, it's better to fix the dent first, as repairing dents may damage the finished surface.
You need to leave your words on the screen longer. I get about have way through, they disappear, and then I have to rewind to finish reading.
A pity this is spoiled by music that hasn't come off with the lacquer.
Too tedious…
DISASTER PAL,JEEZ ...YOU NEED TO GET SIMPLE VASE AND USE IT FOR POLISHING WITH SIMPLE DRILL ...
