The outer is the diameter of the recess the timer rides in the inner stepped for the camshaft, diameter the same as it is.
You trying to make one? Buy one from Gene French. It won't break your bank account.
If your time is worth anything, you can buy from Gene cheaper than you can make it. It's a good item !
