These are called "floor flanges" if you are looking through catalogs, or
want to act like you know what you are asking for at the counter (after
lots of sketching and describing, the guy goes, OH, you want a floor
flange!; Hey I'm a EE, not a plumber))
Use 1/2 inch pipe (1/4 inch pipe for small coils up to 4

You can also use a small square piece of plywood, with some blocks of 1x3
nailed on at the right radius, which is a whole lot easier than trying to
cut a nice circle out of plywood (unless you have a good band saw and jig,
for which cutting circles is easy).
