Yeah, forgot to mention that one.  That was my first plan.  Tried it.  It
didn't work for me either.  The new 2.75 inch hole saw I bought was a bit
taller than my 2.25 inch hole saw so the smaller saw didn't stick out above
the larger saw.  G.

Dennis — don’t forget the method of stacking hole saws of different sizes on 
one mandrel.  If you have an existing 1-1/2” hole and need it to be 1-7/8”, you 
can often slide the smaller hole saw into the larger one and put them on the 
same mandrel; the smaller saw (original hole size) will often stand proud of 
the larger hole saw enough to act as a guide to start the new cut.

Stus-List Enlarging existing hole in glass

[Dennis C. via CnC-List]

Sometimes we're faced with enlarging an existing hole.  There are a couple
of recognized ways to provide an "anchor" to center the pilot bit on a hole
saw.  The most common way is to secure a piece of scrap wood over the hole
(behind or in front) and then drill the new hole.  A second way is to cut a
plug, place it in the hole and secure it with spray foam, etc.

Well, I had to enlarge a hole on Touche' and I thought neither of the above
methods would work.  I dreamed up another method which I've never seen in
my web research.  Here's a link to my write up.  Perhaps someone will find
it useful someday.
