Jim,
It's rare that I can actually contribute to this list, like others I =
gain more than I give but we've recently done this.

The method we used was:

1) cover the twinset with clingfilm, lifting it at the band bolts so =
that you make a plaster of paris blank in the shape that you want the =
v-weight.
2) Put damp sand into some sort of container - we used a planting tray
3) Push the plaster of paris blank into the sand.
4) Melt the lead, we used a gas ring and a iron crucible.
5) Pour the lead into the hole in the sand - here you need a bit of =
skill and judgment - too slow and it will set, too quickly and you will =
make a hole in the sand.
6) Let it set.
7) File to smooth any sharp edges.

We were quite lucky in that the weights ( 4-5.5 kilos/approx 8 -10 =
pounds)we made were the right weight and fitted between the bolts. I =
guess that if you needed more weight, you could extend the length of the =
hole in the sand with the blank to give you a weight longer than 11 =
inches and then drill it to thread the bolt through.

I have heard of people making a mould from the plaster of paris blank, =
be we decided that as we we only making two that this was not necessary.
