Ever try to use a hole saw without something for the pilot drill to
bite into? Very difficult, and certain to make gouge marks where
you'd prefer there be none..


Use the hole saw to cut a 2" hole in a block of wood. Place the 2" hole
firmly over the place you want to cut the 2" hole in the panel, over the
smaller hole. While firmly holding the wood block where you want it, with
clamps if you can get them to clamp it hard, the block will guide the hole
saw, keeping it centered over where it should be from the outside around
the hole saw blade as you press inward to make the new cut with your wood-
block-hole-saw-guide you made.
