I'm considering having the tenon on a YTS-62 neck expanded from its current 27.45 mm. outer diameter to 27.92 mm. diameter, to fit my Grassi tenor's receiver. Is this doable, or too much of a stretch? (no pun!)

Any advice would be appreciated.

Definitely, .5mm is in the zone.

Before you do that, though...are the necks similar in bore, taper, length ? Or are any of those significantly different ???

Placed side to side they look quite comparable. I think I'll give it a try. JayeSF, do you have any recommendations for someone in the San Jose area to adjust this for me?

Thanks for your inputs.

I am not a tech or a sound/ physics guy, but someone posted this and, though odd, it seems to ring true. I pulled out all my tenor necks (7 at the time), and did this test. Remarkably, all but one of the necks were within 5-6c of each other. The neck that was different was the one that I really didn't like on either of the two horns it fits on. One tenor and its neck had too small a tenon/ receiver to try out while interchanging necks, but the neck pitches were the same as the other five common ones...Laugh if you will, but it seemed to work in my case.

Before you have the tenon expanded just try wrapping some plumbers tape or even paper around it --this way you can check compatibility/intonation /tone. Visual observation can be very deceiving. My guess is that the bore dimensions of the Grassi differ somewhat from the Yamaha.

Gabe at Allegro Music in Fremont...he works Saturdays, too....

Not a bad idea if it can work, w/o getting the tape to run up and crinkle in the receiver collar....

Plumbers tape as mentioned above is good to see if its really what you want as an interim.

Well...I like the concept...but wait, though. Even the fella says "as a candidate" neck. Not as a final choice.

I would need to see/hear the comparisons noted here (i.e. fundamental tones on the neck) followed by the neck ON the HORN itself....

I don't actually think just doing the video's test would lead you to a neck which intones the sax correctly.....although I would be inclined to believe it narrows the field....

0.5 mm, you could actually turn an ABS bushing and just use it. I have done this for grossly mismatched mouthpieces.
btw, I'm in Palo Alto, and could expand that for you...just a warning, though, it will be difficult to get it back down in size without pulling the tenon off and annealing it a little. I have had these crack before taking them up and then down 0.5mm (although worse the other way...down then up). Contact me via email (shmuelyosef is also my gmail address) if you want to arrange a time.

Interesting video! Fortunately, the YTS-62 neck and a Grassi Jade neck produced very close responses, including the overtone whistle test.

I agree with shmuelyosef.

And re "0.5 mm, you could actually turn an ABS bushing and just use it..."

Good idea!

Shmelyosef resized the Yamaha tenor tenon over 0.4 mm., polished the tenon and receiver, reworked the octave key and tang for proper engagement, and now I have a very playable horn.

Thanks for working me in, doing a super job with a great turnaround!

Yes, thank you. It's amazing how hard the brass in the Yamaha tenon was....

Glad that it works for you.

Shmuelyosef, sorry for the misspelling! I hope my playing is better than my typing.
