Replacing a A-frame Jack, need to enlarge 2" hole to 2-1/4"

trailmanor, I like your idea of cutting little slots all around and then bending the uncut pieces to enlarge the hole. It's not elegant, but it gets the job done. When you are done, you can clean up the little spikes and shards with a round metal rasp.

And then if the raggedy edges of the hole are still visible after you install the new jack, slap on some caulking around the perimeter to hide the mess. ;)

Depending upon your hole saw chuck, you may be able to mount a 2" hole saw inside the 2 1/4" hole saw and the 2" becomes the center guide for the 2 1/4". I recently did this to enlarge a 2 1/2" hole to 3" but I had a bit more clearance.

bending that thick steel material will be extremely difficult and if that works you will end up with a jaggedy mess unless you spend hours with that rasp.
from reading all of the responses/comments if I was to do this I would bolt a metal plate using existing 3 bolt holes under the opening for the pilot hole, get a decent hole saw of the proper size and drill out the desired hole. easy peasy, no hours cobbling things up with a rasp etc. end up with a smooth opening.no mess, not needing caulking. :)

Well I used the 2 hole saw method this morning and it took maybe a minute and a half.
This was a swing tongue, so I took it completely off and laid it upside down on the lawn.
It would work just as well on a regular tongue except you would be on the ground drilling up.
