In spite of these two aforementioned mistakes the CAD design steps are as follows: It appeared on the underside of the lid.Īt this point you want to familiarise yourself with the dxf file if possible. I also misplace the left hand side of the M. In particular the pivot pin, was situated on the incorrect side of the part. As I didn't, I made an assumption that previous design works were 100% correct. Warning - This is where I made two mistakes.Īs the design is complex and tricky to visualise in 2D, I should have modelled it in 3D including the pivot and the split pin, prior to converting to a 2D dxf for the laser cutter to use. Using a similar design concept to Nazdreg2007 as previously mentioned, I drew up my own design ideas on AutoCAD. Recognising that the spit line was effectively a mirror in heart formation, I set about finding a shape or embalm which has the top (or right hand side, similar to an M).Īfter playing around using a sketchpad, I chose a 'Quaver' over a 'Dove', and moved onto the CAD stage. The next step was to decide what relevant image i wanted in standard formation, that could then be translated into an M. As her name begins with M, I designed an M onto the heart shape. The most important aspect of the design for me was ensuring that the locket was personalised.Īs the locket was going to be a gift to my wife, I first focused on how the locket would appear in heart formation.
I recommend that if you are attempting this project, you: I found that creating the Cartouche locket is a very rewarding project, however there are a couple of very fiddly, time consuming sections that can easily be done wrong and require rework. Once the parts were then returned to me, I manufactured the hinges (one 'split pin' and one 'bent pin' hinge), and performed the final assembly.
Once the locket had been designed, using AutoCAD I created a PDF of my design the work in vector format (a good guide can be found here ) in order for the manufacturer to laser cut work-pieces from 1.5mm walnut using a CNC machine. I highlight the error, so that you can avoid my misfortune.
However due to a miss assumption made by myself, half of the logo inscription was unfortunately on the wrong side. I designed a tailored a logo onto the front which would then transform into the first letter of my wife's name once the locket was twisted into heart configuration. Wanting to achieve a true double hinged locket as per the film, I set about designing the locket in a similar style as research item #3 the 'Illusionist locket: A how to.' by nazdreg2007, whilst also bringing in a few touches from the work of others. I had researched several different methods of achieving the locket hinge including these other instructables: The film's main character: Eisenheim (Played by Edward Norton) describes the wooden locket as a Cartouche which is derived from Egyptian hieroglyphs, roughly meaning an oval with a line at one end.Īs you can see from the embedded video, the locket incorporates a double hinge system in order to twist in half, before the lid can then be opened.
The intention of this project is to design and build wooden locket similar to the one shown in the film The Illusionist.
