Work Holding in the Vice - Milling - page 147

Fig. 6.9. Milling the ends of the bar square: First mill a flat on the end of the block.
Then put this flat face down in the vice resting on a small round bar. Then clean up
the other end, turn the block over and clean up the other end.
Method 3
If the depth of cut is too great for the length of your end mill, proceed as fol-
lows. Put the block in the vice and machine part of one end square. You only
need to go about 1 ⁄ 2 in (12mm) deep - the depth is not critical. Put the block
into the vice with a small round bar under the machined step in the end and
tighten up. You can now clean up the remaining unmachined end, which will
be square with the block. Turn the block over in the vice (it does not matter
if you leave the round bar under the work or not) and clean up the final end
square and to size.
Method 4
An alternative method is: once you have machined all four of the faces, put

will clamp the block vertical without touching each other, you can machine the
end square and turn it over to machine the other end. If the workpieces are
small enough, you may be able to do them four at a time. If the vee blocks
touch each other and the workpiece is not clamped, you can make the work-
