How do I remove the bottom of a food can?
If the bottom is shaped like the top, go ahead and use your can opener. If it's the type of rounded edge that won't fit a can opener, the only way would be to drill a hole along the bottom edge and then cut it out with a saw of some kind --- jigsaw or hacksaw(you would have to take the blade off the frame to feed it through the hole, then reattach to frame).
Regular cans - all sizes - can be done just like the top - use a safe can opener.
I do not think it would be very safe to try removing bottom from a rounded bottom can.
If the bottom is the same as the top, you can use a regular hand or electric can opener. If it is rounded unlike the other end , you may need to poke a small hole first , so that a opener can fit in. Ready to open!

I am wondering if someone can tell me how to cut the bottoms out of tuna fish cans so that I can use them for English muffin molds. I have tried a hand cranked can opener and it doesn't work. What is the secret? Thank you.

Maybe you can use an electric can cutter, I sugguest to leave the bottom in the cans to cook muffins in. You may also cook biscuits in them, good luck.
Most tuna cans have those slightly curved in bottoms that don't seem to come off with can openers as there is no seam.
There are other food products that come in cans that you may be able to substitute instead of tuna cans. I think water chestnut cans and small crushed pineapple cans are the same size and I think they still come in the type of can that you can remove the bottom. Maybe even a different brand of tuna would come in the 'old style' cans.
I made some English muffin rings from a smaller fruit can. I found some small cans of pineapple that you could remove both ends with a can opener.
