it depends how steep for how to lean forwards,but i did was only grinded the end if the rail,and slowly bagan griding more of the rail each time until i could gring the full length of it,but i dunno what your situation is so that might not work is the rail goes across stairs of something.but yh you'll get it
near where i live theres this rail that is so short and steep,its almost vertical,there quite easy to grind
