Andy, the "That'll do speed" will get you broken burned or broken end mills. You'll be surprised how long they last when run at the proper rpm.
Darren, If you can't reach a high enough rpm, just run it at max and reduce the feed accordingly. Not getting slow enough is a different story because even light cuts may still generate enough heat to trash a cutter or tool bit. Getting slow enough shouldn't be a problem for your lathe.
