TUTORIAL


lmost everyone is familiar with
the function of clamps and vices.
They’re a staple of every workshop,
shed, garage, and factory. However,
not everything fits neatly into a
bench vice, or lends itself to easy
clamping. Knowing how to hold your work securely
is an important skill, especially if you are using power
tools or sharp hand ools that could do damage if you
slip. In this tutorial, you’ll learn some basic work-
holding tools and techniques, and some sneaky tips
for getting a grip on more awkwardly shaped objects.

BARS AND VICES
If you want to hold onto something, you probably
need to put it in a vice or a clamp of some kind.
The secret to successful work-holding is knowing
what type of vice of clamp you need to use.
Most vices have sensible names, like ‘engineer’s
vice’ or ‘woodworking vice’, that should give

you a good idea about which vice you need to
choose. For basic forms like bar and sheet, the
process of clamping is very simple, and it doesn’t
really need to be described in detail for this
tutorial. There are some simple tips that can
save you from problems with any material, and
these tips apply to work-holding in general.
Firstly, check the vice jaws and the threaded
bar are clean. Clamping onto a workpiece when
there are pieces of grit or swarf on the jaws will
almost certainly leave a mark on your work. Grit or
bits of swarf on the threaded bar will wear the vice
mechanism and make it more difficult to clamp.
Grease on the jaws will make it more difficult
to hold your work securely without slipping.
If you are worried that clamping might damage
your work, you can protect it with a layer of masking
tape and fit a pair of soft jaws onto the vice. Soft
jaws are made from soft metal or plastic and should
be softer than the item you are trying to clamp.
