The viewer may question why, having fitted the block to the base, will it be necessary
to remove and refit it, the reason being that the block can be assembled on the base
with the vee both parallel with, or at right angles to, the base.
The Clamp Assembly
The clamp is very similar in principle to that used with the Keats in the last issue
but rather than it being a casting it is machined from a piece of steel. I cut a
piece to the overall dimensions and on this marked machine-to lines but to avoid
the slow process of milling away all the surplus material I cut the bulk away using
a metal cutting band saw. With that done, and as accuracy if far from important,
I lined up the 45° line slightly above the vice jaw, just doing this visually, and
milled down to the line, Photograph 13, repeating for the second angled face. The
part was then placed in the vice with it supported on a parallel and the two remaining
When clamping larger diameters the design calls for a shallow curved recess rather
than the normal vee, for this, the part was mounted on the faceplate from my "Four
Jaw Chuck Alternative" and the recess made as illustrated in Photograph 14.
The drawings show a piece of 1/4” diameter steel bent into a U shape and threaded
on its ends to complete the clamp assembly. However, I chose to make a piece of steel
to go under the vee block (as does the U) and with this tapped, screws being used
to provide the clamping pressure. Whilst this needs more than one length of screw,
if used in the horizontal position, it would be more compact with smaller workpiece
With that done and some tidying up, chamfering corners for example, the parts were
finished with a lick of paint and can be seen in Photograph 15.
Elsewhere on the site I very briefly compare the Keats and the Vee angle plate giving
what I feel are their pluses and minuses and suggest some uses to which they may
