I think that would make it worse. You need a good seal between the tip and the body of the oiler so that the oil can unseat the ball.I READ SOMEWHERE LONG AGO, THAT THOSE CONICAL TIPS ON THE OIL CANS SHOWN ARE THE THING TO USE, BUT THAT THE BALL TENDS TO SEAL OFF THE HOLE THAT DELIVERS THE OIL AND THAT CAN BE SOLVED BY FILING A SHALLOW VEE WITH A TRIANGULAR FILE ACROSS THE TIP, TO ALLOW OIL TO FLOW MORE EASILYPAST THE BALL. I HAVE NEVER TRIED IT, AND PERSONALLY DETEST BALL OILERS FOR THE MOST PART, AND WOULD REPLACE THEM WITH GITS STYLE HINGED TOP OILERS.
