Magnetic Shoulder Hubs

I’ve worked on a bunch of things the last few days, the simplest is probably getting my shoulder hubs finally installed.

I borrowed another idea from Victor and used rare earth magnets fix the hubs in place.

I started off by marking and drilling the holes. The magnets I used are 3/8″ x 1/8″ thick from MagCraft. There’s two magnets per hub, and two matching magnets inside the leg.

I’ve been doing a lot of drilling the last few days, and I’ve been extra careful to secure everything before I drill – even when I’m pressed for time or tired of doing it. You can never be too careful.

I then checked the polarity/orientation of the magnets to make sure they’d not repel another magnet. Otherwise I’d be in trouble when they’re presented to the magnets in the legs. Sounds simple but I almost got it wrong at least twice.
I roughed up the back of the magnets and epoxy’d them into place

I took two more magnets and epoxy’d them inside the leg stacked on top of small nuts.

Here’s a short video demonstrating the new magnetized hubs

I’ll try and post some more updates on new things in the next day or so.

Stacks of Magnets

I’d ordered a bunch of super strong ‘earth’ magnets last week and they arrived today. I’m hoping to use them in quite a few spots, hence the tall stacks.

The larger 3/4″ discs will be used to secure the battery boxes to the feet, the rods will be used on the removable back door, and the small 3/8″ discs in various spots, like securing the shoulder hubs to the legs for easy removal, and holding the front blue panel around the vents. I’m also going to experiment with using them to hold panels and doors closed, but they maybe too strong.
