James,
>From my experience, I've found that Tung Oil does NOT do that!=
 However, there are two types of  "Tung Oil" finish that is=
 available. One is the natural Tung Oil w/o any additives. The=
 other has additives to make it set up harder. Under some=
 conditions, the Pure Tung Oil will slightly soften, but it won't=
 get "gummy" as described.
Now, let's blame the real culprit. My suspicion is that someone=
 used Linseed Oil! All of the symptoms described point in that=
 direction. 
I use Tung Oil on the top of my Grand Bench. It has never=
 exhibited these symptoms!! EVER! In the past, (before extensive=
 work/study in Piano Tech and Finishing), I used Linseed Oil as a=
 finish. Each time it was a disaster! The darned stuff never set=
 up! It was pretty, but it was also a mess!
To get rid of the darned stuff, I recommend heavily swabbing the=
 sharps with Acetone and/or commercial grade lacquer thinner.=
 (Yes, there is a difference in grades of Lacquer Thinner.) Use a=
 fine 3M pad to smooth and swab.
