As part of the movement of the Catherine Marshall model the suffragette character raises her head to look at the donkey. I have attached a pull wire at the back of her head. Most of the weight of the head is at the front so the pull wire needs a counter weight to make it work.
Here’s the bottom end of the pull wire. It is connected to a cam follower (the cam is actually not fitted in this picture) the weight on the end of the cam follower is cast from lead. Here’s how:
I took two blocks of 2×1 and clamped them together. Right in the middle I drilled a 20mm diameter hole stopping about 10mm short of the far side.
I made a staple from wire to act as the weight hanger. The ends are 10mm apart.
On the other side of the block I’ve drilled a 5mm deep 20mm diameter hole then two small holes for the staples then threaded the staple into position.
From the underside you can see how the staple fits into position.
In a suitable pan I melted some scrap lead using a blow torch.
Once melted I poured it into the mold filling it right to the top.
After leaving it to cool for a few minutes I unscrewed the clamps to reveal the completed weight. Ta daa!
I made a short Instagram video showing the entire process in just 15 seconds! Click the picture to see it!
