So I finally did it. Replaced the neck corkof my YTS-23 with the Valentino Synthetic I purchased earlier this month. I kind of loosely followed the instructions in the video. I applied tape around the neck where I wanted the cork to start. I rolled the cork and let it take its shape into a slightly larger baritone mouthpiece bore. I applied some contact cement to the neck where the sides will meet. Let it dry for a few minutes and applied the cork. Cut the cork as required under the neck and did my best to keep the two sides in contact. That's where it went so so!
I tried to keep it in place with a mouthpiece but even after 24hours it tends to split slightly.

It works just fine though. But as I was preparing to do this, I dropped the neck and didn't think much of it until tonight when I tried it. The octave mechanism obviously took a hit and didn't close well. Pushed it back into place and problem solved. Except that I noticed once more that the pad was rather worn and needed replacing. I have a full set of pads for this horn but it still plays well enough, so I've been pushing the repad to a later date. BUT, I thought "what the heck with this neck pad!". I can sort it out in no time. Pulled a replacement pad from my stock and just before firing the guns, I thought I should try something...
Being a wine drinker, I have a substantial stock of old corks, preferably from good bottles, the quality of the cork is usually better. Also some from champagne bottles. We haven't had too many occasions to celebrate lately, but that's another story. Anyways, I selected a champagne cork that had a very good looking piece of the right thickness and cut it, then looked up the right diameter's punch and cut the appropriate cork pad. It required a bit of filing to thickness and that proved to be more of a burden with that tiny bit of cork trying to run away from my fingers a few times and me having to search for it in the bin where it had finally landed after going twice on the floor.
I finally had the right thickness and applied too much shellac into the cup... The gun is fine for larger cups, but in this instance it filled the cup in one single shot. Removed the excess and finally set my pad into the cup. So here is the result.

It appears to work fine. I don't know if that's a good idea, but I figured I should try that for a while and see if it's a stable solution.
I made a similar cork replacement for my baritone's pit valve a couple of years ago. But that's most likely what's required given the use of it. It's fine after a couple of years, but I'm not a regular baritone player... YET!
