Was looking into picking up some rare earth disk magnets to make some moving turrets and parts for my models (and for flight bases) but the thought crossed my mind on the polarity of the magnets. Does the polarity cause a problem with turrets and parts being able to rotate 360 degrees, or will I need to say use a magnet and washer approach and not two magnets if that would be too strong? Edit: Was thinking something like this for magnets .25in Rare Earth Magnets

Disc-shaped neodynium magnets are typically made with the polarity going through the flat sides, so it's no problem.

That's definitely good to hear. Yeah just realized they have a pic on there web site from where I ordered those magnets that show the flat sides with the polarity. The fun part now will be lining up the polarity on everything I want to be swappable lol.

That is a good reason to use washers. If you always put the magnets in the main body of your build and put washers in the attachments/accessories you will never have a problem with incompatible polarities.

Yeah I think I'm gonna go to our local Menards and see what they have for small washers (magnetic metal of coarse lol), maybe the same size of the magnets that way polarity won't be an issue. I think I'll use your idea and do magnets in the main body and washers for attachments!

I commonly mark one side of the magnets with a black pen so I always know their polarity. Instead of washers, you could also go in the hardware store and look for other flat metal parts. For example, I often use some kind of small thing triangular metal piece that's supposedly used in mirror assembling. It has the advantage of having no hole in the middle.

Glazing points would work. Hadn't thought of those. Nice catch

That's not a bad idea! I've been kinda wondering how the washers would do since they have a hole in the middle lol.

vimeo.com/173473946Marginally related but here's a little video I made yesterday on how I'm using magnets to make my ships more storage-friendly.
