Is there any tricks to getting the quill sleeve back into the housing? I seem to have a tight one.

When new and properly fitted the quill/head clearance is snug, only a couple tenths clearance. It's tricky to get it started and its only sensble not to crowd a precision fit to assemble it.

First be sure there are no dings or burrs interfering with assembly.

Warm the milling head quill bore with a 100 watt incandecent light bulb (CFLs will NOT work because you are using the filament bulb as a heater) for an hour or two. Stick it right up inside. 50 degrees expansion will gain you about 0.001" starting clearance. When things cool off the original fitted clearance will be restored.
