you woudnt belive it but the job i did yesterday ali door with screw in cylinder, didnt loosen the screws

and guess what happened when i came to put another cylinder in yes it had cross threaded
thanx
now i know why
ray

you should never cross thread anything
if it does not go smooth run a tap through
if the cross drill was done incorrectly at instalattion originally
rasp it out.
Its not easy to cross thread a mortise cyl
you gotta work at it
