[46] Extreme recovery magnet
Author: Thomas Hirsch, Berlin, Germany
... and the search for hidden treasures can begin!
I used the following components to assemble my recovery magnet:
- 7 CSN-60
- 1 aluminium bus 100 cm x 3 cm x 2 mm
- 7 rust-proof screws M6
- 7 rust-proof stop nuts M6
- 1 rust-proof ring nut M6
- 1 static rope of your choice
You also need a metal saw and a power drill.
Saw the aluminium bus into pieces of 6 x 8 cm and 3 x 14 cm. Drill a hole in each center, 1 cm away from both ends.
Put it together as shown in the picture.
Now you have a big recovery magnet with a theoretical holding power of 7 x 110 kg, which you can use to "graze" extensive areas.
Due to its large scale, stuff really sticks to it. In reality, under water rust dust and metal splinters quickly stick to the magnets, which reduces their overall adhesive force.
