Digital Tripper,
Drilling a #80 hole through HARDENED steel is not going to work. I didn’t realize that from the initial statement. That would be a task for an industrial Laser. There are several ways to anneal the part to soften it a bit. One way would be to put it in a toaster oven starting with a high heat and backing the temperature down over several hours. Anything that will get the part hot and cool it slowly should work.
The bushing approach and any other approach is great as long as it gets the job done. Working within your available tools and skills is what it is all about. Look at Willofiam’s ingenious solution to mount his microscope to the lathe. Another mounting solution might look prettier but it won’t work any better.
