Well success..sorta
I got a one-handed spring punch from Lowe's yesterday and a clamp and also a regular punch tool.
Got home, saw that the one handed spring punch you push down on...ugh so I figured what the heck and I used a hammer with it and it made a small hole and then I used a nail I had and tapped with the hammer a little more to make the hole bigger and there ya have it, it was there. The carto really wasn't deformed, it had a very very small divet but hardly noticeable from looking from the side so I guess I didn't hit it too hard. The other punch tool didn't do anything as it wasn't really sharp.
So for the punch experts

is that pretty much it? I don't really have anything to try it out on as I was using an old carto. Also what do you use or recommend for holding the carto in one place? The clamp somewhat worked but didn't know if a vice is better? They had a vaccum vice for about $20 but didn't know if that would work.
Also, question for anyone.....where do you buy your stainless steel cartos from, non-slit or non-punched regular Boge version?
Thanks for the help and info everyone.
