The following page on this very website describes how to make a modified model 18 oscillator coil:

The instructions for winding the primary (outer winding) will be the same.
However...
While the later 14 chassis is very similar to the 18, if I'm not mistaken I think the 14 has a 175 kc IF? (The 18 has a 260 kc IF.) This will most likely make a difference in the number of turns required. (Edit: Yes, confirmed: The 14 has a 175 kc IF according to the service data for this model.)
