Cutting an aluminum quill stem as we speak. Now that its cutoff I realized that none of my saw blades fit inside the narrow opening for the long expander bolt.
Do I need to cut a blade lengthwise? I asked at stores but no one has a blade that's small enough to fit.
Should I try drilling downwards to widen the hole?
'sawzall' blades usually have a tapered end. That might allow you to get started with the tapered end and then proceed farther down the post as you cut a slot.
