... OK folks .... is anyone free & able to help me work through this?
... although i said i was taking oboe in for the repair guy to adjust, he's on med leave and his assistant is on holiday, so i'm totally stuck with oboe that won't play E to C until they get back -- or until i can do it myself
so I've spent some time last two weeks (about an hour or so at a time, can't stand the frustration any longer than that!) trying all the relevent screws discussed in hautbois excellent and helpful instructions, but no luck yet getting it all to work properly at the same time -- it's a case of either one or the other or nothing
I've fixed the F vent, it was a bit bent upwards, and it's seated much better now, Basic F is OK
even though i now know for sure which screw lifts/lowers the little vent over the E, and how to raise & lower the D cap on the F res top screw, i'm still totally baffled by the relative balance between caps E and D, and the rod C to E assembly
The little vent above E has to be closed when E, D or C is down, but if C is down too much and the F res is loosened up, the F res leaks. If the F res is down enough, the E key itself won't go down enough, and the C key (E rod assembly) won't bounce up if the screw isn't fully down and tight ... aaargh!
If the D cap isn't lifted enough E is flat or muffled
the oboe has been through so many different stages of sometimes playing forked F or no forked F, E or no E, D or no D, C# or not, C or not etc. but so far haven't been able to get it all working right at the same time
I start each day with a diagnostic of the current situation after last time's attempt, so here is today's as of now (before i get some dinner to refuel my little grey cells and then try tinkering again)
F# OK
Basic F not a rich semitone below F#, it has sounded 'fuller' and a bit lower, so i'm baffled by this, i'm assuming the little vent above E isn't tight enough
Forked F (with F res only) is a tick sharper than Basic F and fairly bright
Forked F with Eb and F res is comparatively muffled, it has been pretty close to both Basic F and Forked F / F res before
E squeaks
D hardly there, won't speak
C# nothing
C nothing
Eb a teeny bit airy, C screw seems to affect that, although don't actually see it happening
On some days I've been able to get everything down to D speaking, but then the D, C# and C are all the same note, the C pad doesn't close, and the C/C# keys don't bounce up again
(all the springs are on, i've twiddled enough tobe fairly certain it's the screws affecting that bar linked to E and vent above E that's got something to do with all this)
The F res won't drop and close its vent tightly enough until the second little screw (under the C key) has been tightened enough (after releasing it to adjust the E/D stuff) This seems to bring up the E pad again. The screw on the C key doesn't engage unless it's all the way down, and that's brought me to today's status
I just don't get it. What sequence should these notes from E to C be tuned?
down? -- F (balancing Basic & Forked F res) E, D, C?
or the other way around -- settle the C screw first and work up to E?
OR?
Huge thanks to anyone who can spare the time to walk me through this
(still have hautbois notes, but somewhere in there it isn't gelling in my noodle)
