Yep, and a worn out timing belt is a lot cheaper and easier to replace

I can make a gear, not a belt.
Some belts that were made are no longer available. I know that to be the
case because I have a sewing machine with an irreplaceable timing belt.
Unless there's a compelling reason to chose otherwise, I'm for a metal
only solution.

Well, about the "irreplaceable timing belt," I pray to differ. If you
have the specifications of the original, or even the dimensions of the
pulleys, you could either have one made to order or make one yourself
if you're inclined. I know it's possible to get belt material in bulk,
and whoever sells the bulk material will also sell the means of attaching
the ends. I've seen sewing machine belts that are nothing but big O-rings,
for example.

If you really wanted to get it going and aren't too persnickety about
presentation, you could use panty hose. ;-)
