Dodecahedron Dungeon & Dragon Dice Clock
Fun Fact: Dodecahedron dice or 12 sided die. Each face is a regular pentagon. The sum of the numbers on opposite faces is usually 13. Why did I tell you this? Well, I’m a big enough man to admit when I messed up and It’s not the end of the world. The project still looks great, but this one little detail might be the dumbest thing ever. I had this idea for a clock using 12 sided dice for the numbers. Kind of brings me back to the D&D days. (Dungeon and Dragons). I planned the build and had the idea to make a 6 sided board, you know like a one side of the die, place the dice in the right orientation, light it up and done,right? Can you see my mistake? 6 sided is a Hexagon not a Pentagon. Can you say Dumb A**. The back board should have been a 5 sided board, pentagon. Oh well. Lets get into this.
To make a hexagon: Find out how big you want it. I determine the from point to point it need to be 12″ for this clock. Taking in consideration the clock kit purchased the size of dice use and enough space around the border to look good. I started by cutting a 12″ square piece of 1/4″ MDF. Found center, drawing a line corner to corner, then used that intersection to draw two more lines out from the center to all sides. From the point on one edge 30 degree line on both corners and the opposite edge the same. I didn’t have a large enough compass at the time of this drawing. I knew all the information to make the hexagon. Corner to corner was 12″ so from the center to the bisecting 30 degree line needed to be 6″ Used a ruler set at the center move it to where the 6″ mark bisected the 30 degree line. Make that mark so you have 6 points and now you have a hexagon. Way to hard right, use the link below.
After taking way to long to draw the hexagon. Cut the shape out is a lot easier.
You will find you need to remove just a little bit from two sides. Next cut the corner off. This can easily be done with a good miter. I recommend the Icra 1000
I find most clock kits has this little lip, not sure why. The easiest way to make the clock works set flat is to drill a small inset with a forstner bit on the back. Then drill a threw hole 5/16″ or the size of your clock threads.
Use spay glue to glue the snake skin material to the front on the clock. Use a rolling pen or something to get a good bond. I grabbed a scrap piece of wood about 1.5″ wide a 10″ long. set that against each edge and cut the extra material away. Then grab an off cut of the corners. Place at each point on both sides and make a cut. Then fold the material up and flat on the back for two sides. Then using a straight edge at the point cut through both layers or material.
Tape off the area that won’t need glue. Place the tape down. Then by folding each edge of the material up and on the back make a mark for each side. Cut away the tape that covering the area that does need glue. Next spray the glue and fold the material over and press with something round.
Lay out for the clock numbers. I put down tape so I can see the marks. The clock works I used required at least 4.25″ radius. Use a compass to draw a 4.25″ radius circle. Next draw line from point to point, then a line every 30 degrees off that line. The intersecting lines on the circle will be your number location. Use and Awl to mark them. That way you can see the spot after the tape is removed.
Use epoxy to glue the dice to the clock.
Led light was hot glued around the clock works.
Follow your instructions for your clock work. In a nut shell: put the clock motor through the board, on top brass washer, brass nut, hour hand, minute hand, second hand.
Hang the clock plug in the LED light.
