1 - bicycle chain......yes a bicycle chain, you'll seee what's for.
1 - copper sheet
1 - 15mm MDF board (20 x 20 cm will do)
1 - 3mm MDF board (20 x 20 cm will do) ( not on the pics)
1 CD tube case
And also some tools such as:
Bicicle chain tool
4 mm drillbit
130 mm Holesaw
75 mm Holesaw
Table saw or router table, or router, or dremel.
Soldering wire and paste
A visegrip (recommended)
You will also need a template file wich you can download from here, is a dwg (Autocad) file, you have to print it on a 1:1 scale.
Step 1: Getting some pins
So, in this project we will use the bicycle chain pins, ;)
Now,what you need to do is to take your bicycle chain, and dissasembly it several times, in order to get 24 pins, as the images show.
I put my chain tool in the vise to have a better handling.
Every chain link is componed by two pins, two little rings, and two little flat pieces, we will only use the pins, but save the other little pieces, cause they can be very usefull, and you never know when you gonna need them.
Once you get the 24 pins, clean them up very well (i use alcohol), to get all the oil and grease out, and we are ready for the next step
Step 2: Cutting the leaves
Ok, first print the leaf template, and glue it to the copper sheet.
Now cut the leaves!
Regular scissor will do the job (Remember, this copper sheet is 0,1 mm thick)
Once you get them all cut, remove the paper, and we are ready for the next step!
