I'd probably ask on a bike forum, where you might run into a mechanic whose done this many times.
But playing one here is fun, too!
1) Try a carbide bit at SLOW speed. Anything fast drilling into cromo steel is likely gonna shred the bit if done too fast.
2) Watch for cracks.
3) Pursuant to #2, acquire a spare fork from a more modern bike. If you just swap it in you'll also take the opportunity to possibly inspect or replace the headset, too. But don't ask me about threaded vs, threadless headsets here.
