Step 2: Preparing Bicycle Rim
Step 3: Paint Hour Markers
1. The easiest way is to place a mark every 30 degrees from the center. This will give you your hours markers.
2. The second requires some math. First find the inside circumference of your rim. To do this take the diameter of the inside of the rim and multiply it by pi(3.1415....). Now take that number and divide it by 12. This final number is the distance between each hour when you following the curve of the rim.
If you get lucky and find a rim with only 12 equally spaced spokes all the work is done for you.
After you have found your hour markers you need to mask off everything else. I used a piece of skinny electric tape to give me the width of the hour mark. I felt there was no need to mask off the center of the rim.
Using the color of spray paint you picked, I used Regal Red, Spray every hour mark in a well ventilated area. Place 2-3 coats going light on each coat. Give the paint plenty of time to cure before removing the masking tape.
I decided not to place any numbers on the clock to keep the rim clean and simple. If you do want numbers a simple sticker would do.
Step 4: Attach the Movement to the Rim
To attach the movement to the rim start with a thin metal strap. The strap I used is about 1/2" x 5". First start by drilling three holes in the strap. The first hole is in the center to fit over the threaded shaft of the movement the hole will need to be big enough for the movement that you purchased. The last two holes, 6-7mm, will be drilled about 3/16" from each end of the strap. With the holes drilled, bend about a 3/8" tab at each end of the strap with a set of pliers. Now put two more bends equal distance from the center long enough to wrap over the top of your movement. The end result should look similar to the picture. Place the strap over the movement and and then place the movement on the hub feeding the tabs through the spokes.
Now make a metal sheet that will be placed on the back of the hub. The metal sheet should have a large hole in the center to slip over the center portion the protrudes out. This will also stabilize the sheet. Two holes, 6-7mm, need to be drilled out at each end of the sheet equal distance to meet up with the holes in the strap. I rounded everything off to clean it up. You can now paint the strap and the sheet flat black.
With the movement in place, Slide the sheet over the rear of the hub and bolt the strap and the sheet together securing the movement in place.
