This is a clock made fully out of acrylic!
This was originally was my year 13 mechanical engineering college project, we had to research, design and build a project for a stakeholder, this including lots of recording so there is no shortage of photos.
the use of acrylic for a main building material was decided to make a new feature piece, it also is a simpler material to work with, with the limited machinery you find in a college workshop. The clock is fully my design and took about 13 weeks with about 16 hours a fortnight. I wanted something a bit different from the standard clock with three hands and circular design, i wanted to included the look and mechanical workings in the old grandfather and skeleton clock. This is where the open design comes from so all workings are visible so you can see how it operates.
because of its design out of all flat material this clock could easily be all cut out with a laser or CNC cutter, or even 3D printed ,making production quicker and more accurate. Because Autodesk Inventor was used to design the clock, all the files needed very little work before been sent to a cutter or 3D printer.
As the title my suggest the clock is mostly 3mm acrylic, this could be any color weather its transparent or opaque, its your choice. the only other materials are:
- 5mm shaft (brass, steel or other depending on what you fancy)
- back can be thick acrylic, hard wood, metal of any type, or any other strong material
- .Lead, or almost any heavy material for weights, depending on what you want it to look like and how good your cutting of gears are.
- Nylon or other twine for weights.
- Acrylic cement
- Dome nuts
- 80mm diameter aluminum stock for winding barrels. (could be made out of wood)
- 30mm diameter aluminum stock for pulleys (Could be wood)
- Scroll saw
- small hand files
- band saw (not necessary)
- dremel (only needed if engraving numbers, stick on or painted numbers can be used)
- Belt sander (Not necessary, everything can be hand sanded)
- Computer ( to print out gear templates)
- Lathe for metal and some wood work (depends on your changes to the design)
Here is a link to my full project I did with this clock, which will cover anything I miss as this project has a too many parts to cover in one Instructables.
