Any suggestions?

Simple. Find a piece of pipe, tubing, EMT, whatever, of the right
(or close) diameter. Sharpen the end on your grinder and you have a
neat round chisel for the corners.

Nope. The taper on the end would be backwards for a good job. You
would have gto sharpen the _inside_ of the tube for it to make a neat
fit.

True dat.

Plus mild steel doesn't exactly make the best cutting tools. But I
suppose it would work well enough for a one-time thing in soft wood.

I made a pair of similar tools that would actually be more suitable for
this task out of a couple of old screwdrivers someone had tossed out. I
ground the shafts into curved-chisel shapes, one convex, the other
concave. (This was for cutting out index-tab cards out of illustration
board; one light rap with a hammer and I got perfect round corners,
internal and external).

But really, for most door hinges, as long as you're not working on a
historic Georgian mansion or whatnot, just scribing the corners with a
knife works fine.
