One of the Problems with the Clisby is the lack of any gib adjustment for the cross slide. To overcome this Dr. Peter Clark has modified the (separate) central part of the saddle - the "Saddle Insert" - by adding four tapped holes and screwing into them Allen screws which are allowed to protrude, by a small amount, through the base.
It is thus possible to lower the section  (having reduced the thickness of its base slightly) - and then, by trial and error, readjust its height with the Allen screws and remove any play which might exist between it and the cross slide.

Before the tailstock can be slid off it is normally necessary to remove the feed screw handwheel - filing a small Vee groove in the wheel's periphery allows the tailstock to slide over it .

Simple, ungraduated handwheels. One quick, easy  and (hopefully) temporary antidote is to use your desktop publishing system to draw a suitable scale, print it out on sticky paper - and wrap it around the dial.
Those of you who remember "Technical Drawing" from their school days may recall the problem of a line, of an inconvenient length, which had to be divided into an equally inconvenient number of exact divisions. The solution lay in drawing a second line from one end of the first line, at an angle of around 45 degrees and roughly twice as long. This second line was then easily marked out with dividers into the required number of sections. To transfer the markings back to the original line, a straight line was drawn connecting the last mark on the divided line to the end of the first line. Lines parallel to this were then drawn from each division - and so the main line exactly divided into the required number of spaces. No doubt a CAD program could be persuaded to complete this task in the pulsing of a transistor.
