For the reader who is contemplating making some clamps you may like to take note
of the tapered end of the clamp's jaws seen in Photograph 3. These, it can be seen,
have a curved face and were made, before I had a milling machine, by holding the
two jaws face to face in the four jaw chuck and turned with the top slide set at
an angle. It may not though be possible to adopt the method for the larger size clamps
due to the limited size of the through hole of the four jaw chuck.
For details of the vitally important considerations to be taken note of when using
toolmakers clamps, particularly on the milling and drilling machines, see my pages
elsewhere on the site. The pages also compare the advantages and disadvantages of
the alternative designs.
