1/4 punch too big for lock screw holes?

A quick learner from united states says:

Using 1/4 punch for all three holes as per the Swisco video. The middle hole was fast easy.

However, Screw holes not working. Just keeps humping up the metal handle. I keep flipping the handle to prevent to much humping up in one direction, and not even beginning to create a hole Flipped at least 10 times.

Possible the video's recommendation of a 1/4 punch the prob?

Thanks
Tim

Thanks for posting. I'm conferring with a senior colleague on this who specializes in patio door handle sets, and we'll get back to you as soon as we can with his definitive word.

If your are having trouble punching out the holes to install the key lock then I would suggest drilling out the holes. I know on the video it shows punching out the holes. Could be when this particular handle was manufactured the casting was a little thicker. See if this works for you.
