Replating and Refitting Valves: Antique Distin Cornet Restoration Project #8

This video is the 8th in the "Restoring an Antique Distin Cornet Series". In this video, I refit the first of the three freshly replated valves.

Excellent, thank you, very interesting. Much patience and precise workmanship shown!

[@lwilton]

You can add a few drops of oil to the lapping compound if it seems very thick. This will thin it slightly and can make it more free-cutting, so it takes less time and compound to complete lapping. The only drawback is that compound will migrate into the cross tubes off the valve (this is happening now, but somewhat less) so it would be better to clean the instrument inside with some solvent like WD-40 sprayed into it, then wiped with the rag, and finally a final cleaning with some non-oily solvent like IPA or possibly paint thinner. Or I guess you could dip the instrument in your cleaning chemicals.

Bro! That was way cool! Deep South Texas Approves!👍🏾💪🏾

[@LentoidTube]

You're just amazing. Thanks.

[@nichtbekannt]

I would be happy to see more helicons :)

[@jackormrod9128]

Fantastic many thanks

[@lotsabirds]

That's a long process! Coming along beautifully!

[@mattildahubbardo]

Very cool. I learned something today

[@josephervine1119]

definitely a much needed improvement for those valves! I'll have to get the valves replated on a 1930s H.N. White American Standard Baritone that's here in the Brass Lab here at Red Wing, of course, if I end up buying it. It's missing all but two of the braces, and the mouthpipe came un soldered when I was practicing on it, because Greg allowed me to take it home to practice on for the River Valley Band, and it the two solder joints that held the mouthpipe in place just kinda gave up. To be honest, one of the solder joints looked like it had been re-done at some point and it didn't get filled 100%. I'm finding the BIR program very fun to be in, and I am enjoying the process of examining and repairing band instruments!

I went to Red Wing too and I loved it. I was one of Gene Beckwith's last students before he retired. I am glad you are enjoying the BIR program. Art

…so the lapping compound doesn’t wear down the mandrill and affect its precision size?

[@AutismusPrime69]

Of course it does

[@HighRoadMusicTutorials]

Great video! Thanks. How much clearance would you normally expect between valve and casing? If the valve was 0.664 of an inch, should the casing be around 0.665? Is there a rule of thumb?

[@veiledzorba]

What about the lapping compound that was left in the tubing where said tubing joins the valve casing?

[@TheBrassandWoodwindShop]

It is a good idea to clean it out with water and a snake.

[@israelsa899]

Me gustaría tener el equipo para hacerlo.

[@cmorales5]

Costs $$$??? I mean, if those pistons are available new or used, it might be cheaper to buy them, if the valve casing is in shape.

[@EspressoBear59]

Very interesting work. I was surprised you didn’t send the horn in with the valves. Is this you cornet or a clients?

[@davidjohnson5368]

I need a # 2 valve for a German Vox Trumpet, have any lying around? Thx!

[@vuanh2659]

dear sir, I am very interested in repairing this instrument and am doing my own research, don't know if you have a manual or not, I would be very grateful to have it

[@TheBrassandWoodwindShop]

I do not have a manual, but here is a link to the playlist with all of the videos from this cornet. Do you want to learn how to repair instruments?

[@vuanh2659]

@@TheBrassandWoodwindShop yes i am, but i don't have manual so it's hard to work

[@raefblack7906]

Do you reface saxophone mouthpieces?

[@TheBrassandWoodwindShop]

No, I do not feel qualified to do anything with woodwind mouthpieces except to re-cork them.

[@mattjones5987]

What do you mean by "refacing"? I should probably be more informative: most mouthpieces are made from some sort of composite plastic, so there really isn't anything to be done to improve/polish the surface. If you're talking about some more involved repair, please describe it.

[@maz53371]

Где взять такие инструменты?

[@TheBrassandWoodwindShop]

I am sorry, but I do not understand Russian. Do you have an English translation?

[@LaurasLastDitch]

@@TheBrassandWoodwindShop When you get something in a different language, you can copy and paste what the person wrote and "translate" into the Google search bar, and up will pop a translation, which is usually pretty accurate. In this case, it means "Where can I get such tools?"

[@Quadstriker]

“What about the eBay Strad?” We want to know what condition it was in when it arrived.

[@TheBrassandWoodwindShop]

I am sorry it is taking so long to get to that one. A lot of things have come up since i purchased it and I have not been able to start it yet. I plan on finishing a few of my large projects next week, so I should be able to start it soon.

[@Quadstriker]

Thanks for the update!

[@AutismusPrime69]

Chuck that valve up in lathe and turn it down to what you want it. Dont waste your time doing this

[@MrStarbor]

great job man i was using same steps not having those tools ....
