Rob (& other magnet hatch builders):

How much force does it take to open those magnet-fastened hatches?
(The 'pull' of the magnet pair will be less than the published spec because of the veneer and glass/epoxy in between?)

I'm thinking about a day hatch cover - I want it to be waterproof, but I need to be able to open it with one hand, and somewhat behind my back....
So, for an 8" or so cover, how many magnet pairs would I need? (Using the 3/4 x 1/8 epoxy coated magnets we were discussing)

I'd appreciate comments, to guide my experiments.....

;-)
