| The challenge is to make a
new valve stem for an old shower
valve that parts are no longer
available for. Replacing the valve
would mean tearing open the walls
of a custom home and replacing the
shower controls with ones that do
not match the shower. |
 This
valve stem is a replacement that
someone made for the original from
an off the shelf valve years
ago. |
This part
was too short and after
years of use it has stripped out
the valve that it threads into.
The plan is
to make a new valve stem that
will fit the original handle
and have longer threads.

valve stem is inserted. |

This is
the replacement valve stem which
has been machined, notice the
longer threads and the stainless
screw used to flare the splined
part so that the handle can be
press fit onto the stem. |

| Here you can see the jam
nut threaded onto the new valve
stem. This nut is used to lock the
valve stem to the valve. |

| Here you can see the
valve stem pressed into the
internal spline on the handle.
Adjusting the jam screw ever so
slightly makes for a nice tight
press fit to keep the handle from
falling off the valve stem. |
|
|
|
|
|
|
When the
valve stem is threaded into the
valve to the proper depth, the
jam nut locks the stem in place
and then the handle is pressed
onto the stem. |
