I need to cut two 2 1/4" holes in a vinyl vent type soffit. The
holes will be next to each other for 2" PVC pipe to run through. The
soffit vent material is not flat. It's flat for a few inches then has
about a 1/2 dip, then flat again, etc. Any ideas on how to proceed?
It's at the top of the second story too, so access is only from a
ladder. Best thing I could come up with so far is a hole saw?
Also, I figure the back up plan if I screw up the holes is to cut a
square opening with a key hole saw and then find a piece of the same
vinyl soffit, cut the holes in that piece on the ground, then glue it
over the cut opening.

Any other ideas?
