Magnets for door tieback?

    I'm going to have a go converting my cuben shelters to magnetic door tie backs.
    Thought it was worth mining the hive mind as to what size neodymium magnets tarp tent etc settled on?

    The shock cord and cord loc on my tramplite is the best system I've used so far but still a little finiky compared to how easy magnetic closure looks.

    I'm going to go over my duplex copy and try and redo bits I'm not happy with.
    My sewing and sewing machine back then were tragic, and 7 yards of cuben deserve better!
    I'll probably convert it into a tarp by cutting the mesh and floor out too.
    I wouldn't use it in the midge prone areas anyway, and the floor can be easily converted to a stand alone bathtub that'll clip in should I think polychryo wouldn't cut it.

    Check Alpinkiwis youtube Plexamid video. I think he says the ones he bought in the vid.

    Might be useful if you haven't seen it already.

    The Utube vid is what I linked to @gixer with similar request.

    Thanks for the link, look less than 10mm, 6 perhaps?

    Very interesting. It looks even simpler than the Tarptent magnets. I wonder if there's a difference in holding power between the two ways of doing it?

    More elegant!

    Nice bloke, I typed at him a while after this and they were still going strong.

    More elegant than what I was planning!

    I'd say you want very small ones. I would guess something like 4mm by 2mm thick should work. Maybe go up to 6mm but no more. If you want to increase the power of your magnets, go for thicker rather than wider as it's easier to slide rather than pull them apart.

    And, obviously, don't mess up your polarities as I understand that removing Cuben tape is a bit of a pain. ;)

    That's a great help. I've ordered a few different sizes and will experiment!

    I'd be interested to hear your results.

    What's your plan for fitting them Enzo?

    Double DCF tape up around the magnet, i guess?

    From the video, it looks as if he's just taped over the magnet?

    Depends on how strong the magnets are, I'm assuming a sufficiently strong magnet shouldn't rupture 0.51 cuben?

    I was planing to just tape over with cuben tape made from some 0.8 DCF scraps.

    I don't think any reasonably sized magnets would rupture the DCF but it could be a real pain to separate, especially if your fingers don't have enough purchase. Shoot me a message if you'd like some small sizes.

    Very kind, but I've got some on their way :)
    Will let people know what I settle on.

    Any update mate?

    I think 10 X 2mm is a good size/strength. But yet to be tested enough to comment much.
