TAPE MEASURE
In most cases when I top down a sleeve, I put a piece of masking tape next to the sleeve. The tape I have is .005 thick so when my tooling touches the tape I have right around that .005 left to file if I’m not decking. If you have fine feed with an indicator, you can take it a bit closer safely, after hitting the tape.
