Possible Cause and Solution
The alignment pins for the bed extension can be a very tight fit - to help
ensure accurate bed/tailstock alignment. Try putting the pins in the
freezer overnight, and heating up the bed segments with a hot air gun
or dryer. This slightly shrinks the pins and expands the holes they go
into.
Tailstock not aligned to headstock; adjust as described under "Aligning
the Tailstock".
Bed incorrectly bolted to stand causing twist. Ensure stand and lathe
are correctly installed.
Headstock not returned to detent position after it has been rotated.
Ensure that the headstock is locked into a detent position.
Headstock Lockpin not fully seated. Twist the headstock back and forth
to make sure it is properly seated and then tighten the Lockpin.
Dirt or wood dust accumulated in the headstock swivel pin hole.
Remove the Headstock Lockpin and clean out hole.
Headstock pulley or motor pulley loose. Securely tighten the pulley set
screws.
Quill lock is locked; unlock the quill lock. If necessary, lightly tap a
block of wood against the handwheel handle; tap the handle in a
clockwise direction as viewed from the tailstock end.
Build up of dust and wood resin on the quill or inside of the handwheel
thread. Remove, clean, and lubricate the quill and tailstock as
described under "Cleaning the Tailstock".
The quill has been extended too far and is locked against the
handwheel. Push the quill back into the tailstock when turning the
handwheel.
Quill lock is locked; unlock the quill lock.
The quill is damaged; turn the handle to expose the quill and check for
marks along the quill, especially on the edges of the slotted keyway
Remove the high spots with a smooth file and test the quill travel.
Replace the quill if necessary.
Tailstock adjustment plate not adjusted correctly; adjust as described
under "Aligning the Tailstock".
Dirty bed ways and underside of tailstock body. Clean bed ways and
underside of tailstock body with a petroleum-based solvent.
The inside of the bed has a high spot. File the area with a smooth flat
file until the tailstock moves freely.
The tailstock adjustment plate has a rough spot or a burr. Remove the
tailstock and file the plate with a smooth flat file.
The machined flat surfaces are not flush. File the area with a smooth
flat file until the tailstock moves freely.
