I need to replace the weights in some of my sash windows, because the
existing ones aren't heavy enough. I need to use lead because less dense
iron or steel weights would occupy more space than is available.

I have some weights on order which are long pieces of 1.5" square bar
(with a hole through the middle for the cord) which need to be cut to
length. I would also like to drill a 1/2" horizontal hole near the top
of each weight to accommodate a knot in the cord, so that I can use the
existing cords which are not long enough to go to the bottom of the weights.

What's the best way of cutting and drilling lead? I've done some
experiments on a lead 'brick' which I happen to have (which started life
as a counterbalance weight on a drawing board), and not found it too
easy. A normal hacksaw seems to be too fine, and drill bits seem to bind
when they get a little way in.

Any ideas? [Would an angle grinder help? g]

Might be easier to tie a knot that will fit down the existing hole,
and wack a nail in the side to stop it coming out. (If necessary split
the cord before knotting.)
