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

No need to weld a plate on to use to center the hole saw. Do like Cummins12V98 says. Clamps will work, but you can also add bolt holes to so it can be bolted down using the bolt holes for the existing Jack.

yep, much easier to bolt it using existing hole pattern than clamping/welding etc. and when you get done with the hole saw your jack won't look like a cobbled up mess like some other suggestions would.
