Making a gasket ?.

I don't have a drill press so drilling out the center hole is out of the question. I'm thinking of buying a jeweler's saw and cutting it out slightly undersized, then filing to finish.

Make a punch and smack it with a hammer.

Grind the end of a 1/4 socket sharp to make a punch.

I feel like a punch would tend to deform the plate.

Thats why you have a backing. Punching free air yeah, with a backing to keep it from deforming you should be ok. Wish @Wrench was back, hes the gasket master. Check out his post on making gaskets.

Use the old gasket and tape it to the new one and go around the inside with a utility knife until the middle falls out, copper is just soft.

A empty .223 or 5.56 case makes a nice gasket punch for 1/4" or 6mm bolt. & when you mess it up you just grab another one. I use a piece of 1/2 aluminum plate for a back up when punching gaskets.

Drill out a hole in the center than use left/right angled tin snips to cut. Yellow handled snips are straight cut, green right cut, red left cut. Does a nice job if you take your time.
