  What is the process to remove the Ignition Key Lock Cylinder from the Steering Column in a 1940 Ford. Thanks for any advice.

  On the bottom of the ignition "drop" - just below the lock cylinder, you'll see a small (1/4" diameter) pin. You must remove that to remove the lock cylinder.
That pin is serrated and was simply pounded in. It wasn't really made to be serviced.
I have removed many of these and you can too.
I would strongly suggest you center punch that pin and start drilling with a very small diameter center drill. Once that step is complete, I use an 1/8" drill bit first, then a 3/16". You should, if you were accurate in your drilling, be able to fish out the thin sleeve now remaining from the pin.
Once I have removed the lock, I drill and tap for a fine thread 5/16" pointed set screw. That way, if I ever have to remove the lock again, it's a simple procedure.
I place a very small dab of gray clay in the socket of the set screw. It appears just like the authentic pin

  In my opinion, the center drill is a crucial step. A regular drill bit will tend to wander off center. As the pin is much harder than the column drop, you want to stay centered.

  this is how I have done it. Drill a tap size hole around for a 8 or 10 machine screw Then tap it for the screw you selected. Screw a rod into the plug and make a simple puller. A few taps and it comes right out. The do as Kube says and tap it for a set screw.
