Smoffat's advice is admirable,but I'm hoping it's a last resort.
I'd first call Kirk of Sota!He's the owner and builder "Extroadinaire",so may have a simpler solution.
Yet,I'd still attempt to shine a high power light into the table,where the motor mount is(this has some addional space to see down into the table).Do this from above,without moving the table,and DO NOT use a two chair approach if needed.That can allow a chair to move and the table will go KAPUT to the floor.
Use the spacing between a two part table,which is more stable.
If you can see the belt at all,attempt to get at it with a tweezer or some kind of little hook(like a knitting hook).
All in all,it's not going to be a big deal,and will work out just fine.
good luck
