A quarter turn is too much. You should only turn the wheel a maximum of 1/16 turn. Sanding should be done with just the sand (not the paper) touching the workpiece. Patience is the key for drum sanders. Courser grit sandpaper will help remove material faster if that's your goal.

Need the size and thread pitch for my Delta disc/belt sander wheel set screw
Probably an 8-32 or 10-32 (possibly a 10-24) or even a 1/4-20. You can get small packs of these size screws at most hardware stores so would be cheap to busy one of each and try and once you know the size you can get a set screw of that size. Another crude way is to see what size drill bit will fit into the threaded hole. If a 3/32" goes but a 7/64" doesn't or fits tight, it is a size 6 (likely 32 threads per inch (TPI). If a 1/8" bit goes but a 9/64 doesn't or is really tight then it is a # 8 size. (8-32 is most common). If the 9/64 goes freely but a 5/32 doesn't it would likely be a 10-24 whereas if the 5/32 does go but an 11/64 doesn't then figure it to be a 10-32. Finally, it could be a 1/4-20 if a 3/16" bit goes but a 13/64 doesn't or is fairly tight. If it is really big and a 1/4" bit fits the hole then it is likely a 5/16-18.
