I'm putting a new motor on my lathe that has a bigger shaft than the old

I want to make sure that this is not a Bad Idea before I do. Is it OK?

Considerations so far: there is plenty of meat in the old (cast iron)
pulley; the keyway will be reduced to 1/16" deep, but that should be
enough (?).

I sure hope it's OK; I've done it a few times. :-)

But use the lathe (or mill, if that's how you're doing it) to stroke the
keyway deeper. It's a very useful thing to know how to do, and it's easy,
and the tooling is inexpensive.
