doorsexteriormetal
I am wondering about drilling/screwing into an exterior metal door. I want to install a dart board & back board onto the back of my exterior door that leads into the garage. My worries are as follows:
– Will this damage the integrity of the door (i.e. since this is probably a fire door, will this be a bad idea?)
– Will this cause the door to lose insulating value for the basement?
– What's inside these doors, will it be able to hold a dartboard mounted on plywood?
Thanks!

The recommended rough opening for a 36" x 80" door, is 38 1/2" x 82". So you're basically looking at something like this.
Basically, you'll have to fill the purple area with framing. Which means you might have to either use thin planks on the sides, or cut into the walls to install framing.
The rough opening (blue) around the jamb (brown) will be left open, and shims will be used to make sure the jamb is perfectly level and plumb. This area will be covered by the casing, once the door is trimmed out.
Finally the door (green) will be fitted within the jamb.
The 1 3/4" you're seeing as "assembled" dimensions, includes the door, the small gap between the door and the jamb (3/16"), and the jamb itself (11/16"). This is typical of prehung doors.
It is of course possible for an individual to make a door that provides a normal level of performance. The probability that a person without knack for or reasonable experience performing finish carpentry is, however, rather low.
To perform to a normal level, a door needs to fit within a tight tolerance and maintain dimensional stability without twisting or warping. Typically, doors which are not manufactured in a factory are fabricated in a professional carpenter's workshop. It's not really a do it yourselfer's project given the standard to that appears in the photograph.
As an alternative, a used doors from local building recyclers are a reasonable option if a person is patient and diligent. Modifying an existing used door is another option that requires less specialized knowledge.

I would look in to magnets. I recently purchased a magnet and hook to hang a Christmas wreath. It was about $5. It is strong enough that the easiest way to remove it is to slide it off the edge. I checked Amazon has them rated for 8 lbs.
