Accelerate tung oil curing?

How can I help it along? Put piece out in direct sunlight? Have a small fan blowing air on the piece? Something else?

Also, you can get "polymerized" tung oil that cures faster.

If you didn't use polymerized tung oil, you're screwed. Tung is an air-drying oil, but warmth probably helps polymerize it. Strong, hot sunlight might cause a bubbling, though. I wouldn't try that.
Next time, try wiping on some Waterlox. I get 3 coats on the first day, then one more coat per day afterward. 3 wiped coats provides a minimal but complete finish.
But always remember the #2 rule in finishing: Do NOT rush it. #1 is: Prep well and thoroughly clean before finishing.

A few drops of Japan Drier should accelerate the curing of Tung Oil.

It usually cures fairly quickly IF you wipe the excess dampness after 10-20 minutes. If not it can take a long time to cure. I found out the hard way with a Danish oil finish (similar process) a few years ago. I placed the item in direct sunlight and it sped up drying. Do this after you give the piece a light wipe with a soft, dry rag to remove excess oil.
