Magnetic jack pads

[bucketlist]

@bucketlist asked where I got the Remove Before Flight keychain tags.

If I just search "Remove before flight" on eBay, I get several seller hits. Here is a direct search link with results. A 3-pack is common. I suggest ordering two (for 6 total), which gives you 2 extra after putting them on your jack pads.

One can be a key chain, or whatever. I put one on a lanyard, and then I may hang it on my steering wheel as a "Don't forget" reminder to check something before starting or driving my car.

Note that the key rings didn't work with my Quickjack so well, so I modified the pucks such that the tags screw onto them directly. I updated the photo in my previous post. I know I saw eBay jack pads that already come with the RBF tags but I didn't see them in those results.

I appreciate all the suggestions. I'll swing over to harbor freight and see if they have one of the Daytona ones to match my jack and stands. If not, Amazon here I come.

Nice, I love those Daytona car jacks and they are very reliable. Good luck finding those magnets at Harbor Freight. I've been trying to get one from there for 2 months now, but they keep selling out. I've checked other stores in my area, same issue. I guess I'll have to order online like others.

I have been using a set from eBay which looks the same as pictured in posts 2 and 5 for a couple years now.

I've noticed that at least one puck does not attract as strong as originally and can fall off before I get my Quickjack positioned.

I think the concept is good but the implementation is a bit lacking. The pressure on the nylon block is so great that it steadily wears down. That exposes the magnets more which can then crack. Then the puck does not hold on as strong. But recessing the magnets more only reduces the attraction force.

A cobalt magnet's pulling force increases faster with diameter than with its thickness. Obviously the magnet diameter is constrained by the channel width.

To me, the design could be improved if they were to put in a third magnet. So these pucks could be modified DIY, but that involves sourcing the appropriate magnets as well as drilling with a flat-tip bit such as Forstner. If mine continue to degrade perhaps I will try that.

Good information thank you! I figure with all of these different ones they are selling online, some quality issues exist. But since most of these cost around 10 bucks, they might last awhile before chucking out and getting another one.

I have the magnetic ones from Harbor Freight but...I also still use a short section of 2"x4" wood. Just make sure grain is perpendicular to pinch weld.

Their displays are not very easy to sift through and find those jack pads. I almost left (for a second time) without one because they are sorta hidden. Look along the corners of the posts that hold up their multilevel display section of jacks. They're camouflaged in there with a lot of other shit.

If you don't want to go back or they truly are out of stock, just get a $10 one from 'zon. They're all about the same it seems.

It seems that the amazon ones, are 0.86 inch in depth vs the HF ones which seem to be 0.5. Not sure if the taller ones aren't better. Do the amazon ones rest on the pinch weld or the actual car body metal? The deep ones have a good chance of not resting on the pinch weld. I don't know if thats good or not.
