This is getting out of control with great ideas.
Drilling it out so the wheel can be removed is a simple and inexpensive job. If he doesn't have drill bits, he's not going to have all the other niceties mentioned. Buy some decent bits and don't run them so fast. Learn how to use them properly. There are important details to that. And use cutting oil... any oil.
This type of tool purchase will continue to be useful for the rest of your life on many other jobs so it's not a one job deal.
If it's spinning on you, you will likely have to remove the wheel, drum, and hub as an assembly as mentioned and work from the back. You might be able to remove the hub with an axle nut or two protecting the threads. Flip one over(castellations in) and leave it slightly above the threads. Pop on it with a heavy hammer. Sometimes pulling on the tire, wheel or even lightly prying on the hub will help offset the blows. Be gentle with the prying though.
