💡 Why does spindle wobble ruin precision when driving large screws?
Runout spikes usually happen when gritty debris jams between the jaws and the Morse taper. Cleaning the contact surfaces and tightening the lock nut kills the shake fast. This handy fix keeps your boring bars steady when pushing through cast iron or hardwood panels. Watch these quick steps to keep everything locked down:
- Wipe the tapered spindle clean before sliding the sleeve onto the nose
- Spin the tightening ring until the jaws bite deep without slipping back
- Test the spin rate with a dial indicator to confirm sub point zero one play
