Fine Jewellery Techniques (JEW4035)

13/04/2018 - Final Build 1

First day working on my final orrery piece.

I printed out the CAD design as a cutting plan and started on the smaller cog.  I tried cutting all around the teeth in one go but found it to be very uneven. So I cut out another by going round the outer circle first, then cutting between the teeth separately.  That worked much better and I tidied them up with various needle files.
I then used the same technique for the larger cog.

I also cut out the large circular base plate and arm strip.
Finally I made my 3 bezels from fine silver (because I'm a wimp) and soldered the “earth” one onto the small cog

We also got our 40x40mm perspex box today.  It's mainly so we can check that our piece fits the size requirement, however I picked a blue one that will go with the abalone, so I could use it for the final presentation.
