Discovery 48 air tightess

(1/5) > >>

SJB:
Has anyone tried sanding the front of the comb on the Discovery 48 to make it more airtight?  The plastic mouthpiece feels very nice but it doesn't put any pressure on the center of the slide/comb because it cannot be curved like a metal mouthpiece.

Thanks in advance.

Don't own a "Discovery" one, but I've yet to own any Chromatic that didn't benefit from "hand done" flat-sanding; especially a "lower-end" model like the Discovery.

I've only had mine apart once, just to clean. I had a leakage problem when I put it back together because I had one outer edge of the mouthpiece against one of the reed plates. If I recall correctly the edges of the mouthpiece fit over the reed plates. Worked much better when I took it off and put it on again.  I don't know if taping the slide would help. I'm still new to the Discovery so I don't want to try any modifications. It may get better the more I play it. It does seem to be a bit quieter than my other chrome. When I took the screws out I took note of the tension. The mouthpiece screws were just snug, not tight. I noted the position of the screw slot and put the same screws back in the same holes and with the slot stopping in the same position. The reed plate screws were pretty tight. Good luck. Let us know how, or if, you resolve this.

Well here’s what I did. I took it apart and adjusted the offset of the highest reeds. I then put it back together being careful not to over tighten the reed plate screws. The surface of the comb is sort of molded and not really sanded, but since it is a 2 piece slide (no back plate), I’m thinking that sanding would only make the slide fit looser. There’s a limit to how tight the mouthpiece can be because of the way the it wraps over the comb on the ends.  Anyway it seems to being playing much better now, and I guess it just is what it is.  Not as airtight as my Hering Special 48, but the Discovery tone is better/richer.

Thanks for the update. The lower half of mine works better than the upper half. If I can't adjust to it I might have a look at the gaps. I think the Discovery has the thicker reed plates.
