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]

get a new cheap cross cut saw at a guess.

You need a wide kerf or it tends to clog.


Do you mean a wood saw?
