Dear Friends,
My oboe has been very unstable as of late. Upon examination I have found that the cork that is linked to the lower joint and bell keypads has come off. I am trying to determine what thickness of cork would be appropriate to use. Any suggestions would be helpful. Also what type of adhesive would be most effective to secure the cork to the surface.
Thank you in advance for any assistance that you can offer.
Sincerely,
Charles M. "Chuck" Cobern

Do you mean the linkage corks on the undersides of the trill, con bar and bell key linkages? If they've all fallen off, then you ought to have your oboe serviced as chances are others are likely to fall off as well. While Fox do use nylon tipped adjusting screws, some keys still require key corks for both regulation and mechanical silence.
Personally I'd never use natural cork on the linkages and use tech cork (gummi-kork, rubco, hycotex, etc.) as that's much harder wearing. You will need a sheet of that of around 0.3mm to 0.4mm thick and best to use contact adhesive to glue it onto the keys, only you have to make sure all the previous adhesive and remnants of cork have been removed and the surfaces thoroughly degreased before applying a thin layer of adhesive to them and also to the tech cork, then leaving for several minutes for the solvent to evaporate before joining both glued surfaces together, applying some pressure to determine they're bonding, then trimming up the excess tech cork with a fresh razor blade or scalpel blade.
I'd strongly recommend you don't do this yourself if you've never worked on oboes at all as the chances of having to do any adjustments after replacing the key corks will need to be done and that can involve having to bend keywork, which is not advisable for a novice to do. Leave it to the professionals and oboe specialists rather than a Jack or Jill of all trades who rarely works on oboes.

Dear Chris,
Thank you for you help on this problem. I believe (the standard nomenclature escapes me) it is the linkage across the lower joint and extending to the bell. The related keys are the the lower B and B-flat.
I am sorry for having taken so long to respond, but I have been down with a cold and this is the first opportunity I have had to check the board.
Thanks again. I think I will be taking your advice and take this to an oboe repair person who has worked on my Fox before.
Peace.

There's no need to clamp down anything that's been correctly bonded with contact adhesive.
Natural cork should never be used under adjusting screws or other linkages as the screw tips and linkages will chew through it in next to no time, plus the fact natural cork creates too much friction on sliding linkages which will make the action creaky and sluggish or cause things to bind up. Oboes that use nylon or teflon tipped adjusting screws don't need silencing material under them.
Natural cork has its place for key feet as it's easy to adjust by sanding (if need be) to get the regulation and venting just right.
