Other then gutting my first job was to remove the rusting propane tank holder and install a new jack. I measured the A-frame jack hole at 2 1/4" and got a good deal on a bulldog 5000lb jack for $39. Unfortunately when I went to install it, I discovered the lower plate cut out was only 2".
Apparently this was common in the good old days. Most were 2 or 1 7/8" OD on the lower plate! So either I return the now scratched up bulldog and special order an inferior Jack or make the hole bigger. I tried honing/reaming the bottom hole and it was sort of working but I was going through grinding discs too fast and would take forever.
The solution was to use a hole saw. How do you use a hole saw without a drill to guide it. You cheat. I screwed a 2x4 to the Jack hole.
Then drilled a 2 1/4" hole in the wood.
I then used the wood hole as a guide to drill out the steel lower plate to 2 1/4".
Drilling slowly with lots of oil, it was surprisingly quick.
Now back to grinding and hacking!

we just did ours and use a dremel and slowly grinded it out, it took quite a while and a lot of bits later lol
