Step #1: Plan layoutPrevNext
- Choose a surface.
- My home-office door is almost never closed and the back was not in great shape to begin with. I was therefore not too concerned about messing up the finish, but you may want to be more careful.
- The surface needs to be smooth enough for the hubs to stick. Besides a door, a mirror or a piece of cardboard or masonite hung on the wall would work.
- Draw a plan.
- I used Adobe Illustrator to figure out how many discs I could fit on the door and how I wanted to lay them out, but InkScape, SketchUp, or plain old pen and paper would also work just fine.
- A full-size CD is 120 mm across with a 15 mm hole. The template allows for 15 mm of clearance between CDs, as well, which puts them 135 mm apart on-center.
Step #2: Print and cut templatePrevNext
- Print template at full size on heavy paper.
- Cut out along dotted lines.
- I used a swing-arm paper cutter, but a pair of scissors or an art knife and straightedge would work just as well.
- Punch holes.
- If you cut the template edges accurately, a US-style single-hole punch centered on each short edge should put a hole in just the right place.
- The holes do not have to be precisely positioned, so it's OK if you miss the black circle by a little bit.
Step #3: Lay out gridPrevNext
- Use an erasable marker to do your layout work. You may want to perform a discrete test, first, to verify its erasability. I used a wet-erase overhead projection marker.
- Measure and mark centerline and position of first CD.
- I measured and marked the center of the door at the top edge, and right above the knob, and connected those two marks with a line.
- Then I measured 16 cm down from the top edge, along the line, and made a witness mark to position the center of the top CD.
- Iterate template over surface and mark grid locations.
- Start with your witness mark, and work along the centerline first.
- Once you've got the center column of discs positioned, finish out toward the edges.
Step #4: Affix hubsPrevNext
- Peel the adhesive off the back of each hub, center it over one of your grid marks, and stick it in place.
- Once all the hubs are attached, erase any remaining layout marks, e.g. with a damp cloth.
