Will it work to prevent leaks?
I was going to suggest 'Stag' until I saw how much it now is. Ouch!No, plumber’s tape might be a temporary solution but it needs a tech.
You purchased a brand new S20?Ny brand new King Super 20 (KMI) was suffering from this. The "SML" neck didn't fit. I gave up and bought a "The Martin Magna Tenor" -59. I used plumber tape, sent the sax to Stockholm for warranty repair (twice) ..... .
Right, people said it wouldn't work.it made a big mess . Flakes everywhere
I talked to him, he said I didn’t have to do anything. The neck fits okay and I’m overreacting. All I did was a small quick swipe with 1200 grit sandpaper, not very abrasive. According to this article this is a legitimate way to shrink a neck that’s not fitting well.Right, people said it wouldn't work.
Go to a tech.
I bought a new King Super 20 tenor in February 1983. KMI model 2416K with serial nr 871XXX. I masked the name of shop at Drottninggatan in Stockholm and the name of the guy who was in charge for the wind dept. I bought a Berg Larsen ss (straight bill/beak, M) 115/0 as well a few days later. 450.00 s e k!You purchased a brand new S20?
When ?
And it came with an SML neck ?
And there was a tech in Stockolm which did warranty repair on Kings ?
And you just gave up on the new S20 because a tech couldn't make the neck fit right ?
So many questions..... 😵

So the problem was actually the opposite of what you had implied, then.I talked to him, he said I didn’t have to do anything. The neck fits okay and I’m overreacting. All I did was a small quick swipe with 1200 grit sandpaper, not very abrasive. According to this article this is a legitimate way to shrink a neck that’s not fitting well.
On the positive side, I no longer have problems with it getting stuck.
