Your machine was normally used by amateur to form aluminum angulars to get parabolic ribbons to be used in large parabolic EME dishes for 70 cm and 23 cm.

The pressure applied over the central pulley depends on the material of the wire to be formed.

Annealed aluminum or copper wires versus cold drawn aluminum or copper wires requires completely different pressure applied over the central pulley to get the material permanently stressed.

If your effort failed probaly your wire was cold drawn wire and not annealed wire

I think the OP is saying he tried forming wire around a bucket, and that effort failed. I think he's looking to make a pulley system.

But, I could be completely wrong.
