DIY: Magnet Fishing Rig with 2x Ferrite pot Magnets

Double ferrite pot magnets rig, perfect for smaller items

In this post I will show you how I made a magnet fishing rig with 2x Ferrite pot magnets. These magnets has a pulling force of 110 lbs each.
I think this is the perfect rig when searching for fishing lures and other smaller items, of course you can add more, bigger or smaller magnets. But this works really good to catch some awesome stuff!

What I used:

  • 2x 3.80″ Ferrite pot magnets. (Click on the “Check out with Amazon” to buy them yourself)
  • 2x M10 Female Eye bolts.
  • 2x M10 Bolts of any length that fits.
  • 4x Washers for locking.
  • 1x 1.25″ Square steel tube, 12″ long.
  • 1x 100ft Paracord 550 rope.
  • 1x Empty bottle of soda with cap.

How I did:

First of all I took my 12″ long 1.25″ Square steel tube and shorted it by 2″. I thought that 10″ long would be perfect for my 3.80″ ferrite pot magnets. (Of course you can use the whole 12″ pipe).
After I cut it down to 10″ I drilled 2x 3/8″ holes in the ends, all the way trough the pipe. (about 1.25″ from the edges)
And when that was done I painted it with a black anti-rust paint for outdoor use.

When the pipe was totaly dry I took my 2x female eye bolts, 2x bolts and 4x Split lock washers. (Found both bolts and the washers in my garage)

Placed one washer on the bolt and sticked it in from the side where the magnets are, then one more washer on the other side. Ended with the eye bolt and tightened as picturedmagnet fishing rig with double ferrite pot magnets

Next step I did was drill a hole for the “float device”. (bottle of soda) First of all i started to search for a small metal screw and some thing to seal the hole in the cap. (Don’t want any water in) Found a potential screw and a piece of rubber.

I drilled a small hole in the center of the pipe and the center of the cap. Important to drill a smaller hole than the threads on the screw!
(Sorry for the rope, got a bit too excited and forgot to take pictures in the right order..) magnet fishing rig with double ferrite pot magnets
Took my electric screwdriver and let the screw make its own threads.

Result

Here is the final result! And a short description of the Paracord and how I tied it.

I use a 100ft Paracord 550 (Color: Olive drab). It´s a thin (5/32″ Diameter) and really strong rope/cord that has a breaking strenght of 550 lbs.

I Just let the rope through both eye bolts (With a simple knot on each eye bolt). And tied it back to the rope with a “Blake´s Hitch” knot. With this knot I could still move it to get it straight in the middle and then lock it with a small cable tie. That´s also good for extra safetymagnet fishing rig with double ferrite pot magnets
