: The strength/number of the magnets you use and the width and thickness
: of the gasket will determine the holding power on the hatch cover.
What combination of magnets are you using, and how did you arrive
at that? I think that's my one concern with the magnet idea is
finding that they're either too strong or not strong enough. Is
it pretty easy to test various configurations? I guess I'm not
completely clear on the construction method, but it seemed to me
that you wouldn't know how much pull you'd end up with until after
it's all laid up and the epoxy is hard.
I'm considering using disk drive magnets because I have access to
a fair number of scrap disk drives. These are rare earth magnets -
probably the same material as the ones Lee Valley sells - but they're
an odd shape. They're strong enough that if I put one on my fridge
I can't pull it off, I have to slide it to the edge (scraping the
paint and causing serious domestic disharmony). I'm just not sure
how I'd figure out how many to use.
