HOW-TO Remove The Y-Axis Leadscrew
here's how to take the Y-axis
leadscrew apart from the retaining block. here's how to remove the X-axis leadscrew.
| it's easy to do. all you need are some blocks of wood
(or vise or similar thing that has a gap in it) and a hammer
| rotate the y-axis handle counter clockwise as far as
you can go.
remove the two socket head
screws holding the retaining block to the base.
keep rotating the screw until it disengages from
the nut. (you don't need to undo the x-axis first)
take the handle and key off the screw. this is
what you get.
| if you've taken the x-axis screw apart you'll notice
that it has thrust bearings. not the case in the y-axis.
so, take two blocks of wood taller than the length of
the screw and set them under the retaining block.
start tapping the front of the screw (where the
handle end is) with a hammer. please use a block of wood, brass or
something that won't damage the threads.
here you see a picture of the assembly half-way
| keep tapping away. now the screw is removed from the
| here is a close up of the screw
| here is a close up of the retaining block. imagine
that - no bearings!
i've ordered a 5/8" x
8TPI acme screw and delrin round bar. hoping to smooth the action of the
screw and reduce backlash. even a new bearing block will be made.
check back here as this procedure will be
documented and the results posted!
