Whilst the Myford Super 7 top slide has a full 360 degrees rotation this cannot be
fully used as its handle fouls the cross slide when it is almost parallel with it.
Having a need to set the top slide almost parallel to the cross slide, Photograph
1, I made the knob seen in Photograph 2 as a temporary replacement for the handle
This arrangement will be more than adequate for the very occasional use, especially
if the top slide is only to be traversed over a short distance, for a longer distance,
it may be easier to use a large screwdriver in the screw securing the knob.
The normal handle is mounted onto a tapered mounting on the leadscrew but I chose
to place a parallel hole in the knob, therefore locating on its front edge only,
more than adequate for its limited us. It would though be worthwhile very lightly
chamfering the edge of the hole.
