In Response To: S&G: Magnetic hatches (Tony Calvert)

Hi, Tony:

I'd be careful about allowing any significant space between magnet and metal. Somewhere I've read that magnetic force diminishes with distance cubed. You'd have to fit and fiddle for small and consistent gaps at each 'catch'. What bothers me, and I've thought about magnets, is that mechanical forces may pry a 'catch' (and the hatch) open at just the wrong time!

Very best! Rick........

: I am in the process of creating the hatches on a CH16. I am using 8 1/2 x 1/8
: rare earth magnets to hold the hatches down and what i need to know is;
: Can i place a 1/16 weather strip in between the two magnets and still have
: enough holding power to keep the hatches in place? I also need to know
: what is the best placement of the magnets to get the strongest pull across
: the hatch? I am thinking that a magnet in each corner and one at the
: mid-point of the sides is the best option but any advice would be
: appreciated.

: Thanks Tony
