I just bought a used kasson pool table that needed new rails. When i put the new rails on they seem to angle upwards instead of slanting down slightly like most pool tables I've played on.The rails are sitting a little high at 1.5". I'm beginning the think the angle where the cushions meet the subrails has been cut too wide. Is this something that can be fixed? Or am i just attaching the rails incorrectly? Any input would be appreciated.
