: Quick question for those who have used rare-earth magnets for
: hatches. What size/strength should I get to use? And how many
: per hatch lid? I am planning on fairly typical sized rectangular
: shaped hatches on my next strip-build, and would like to use
: this as it really seems to be the cleanest and simplest method.
: I am thinking one pair of magnets in each corner of the hatch.
: Too much, too little, or just right? I have already done a forum
: search back 2 years, but couldn't find any specifics.

I've done the magnets on a Guillemot and am removing internal bungies to put them in my Great Auk.

I used 1/2" diameter by 1/8" thick and put them about 6" - 7" on center on the Guillemot. This is a little too far apart on the curved hatch on the Guilly. The hatches want to open up at the edges, not quite enough clamping pressure.

The Auk is getting the same magnets about 5" on center. Much stronger clamping, I'll need to install a strap to be able to easily open the hatch as the finger notch is not deep enough and it actually hurts my finger to try to open it with a fingertip.

The internal bungies were a PITA for me, the magnets are much better and more elegant IMHO.
