It's about time I did another update!!

Since the end of the summer I have been busy with jobs on my home, I am know getting back on track with the business at hand…..finishing my Robots.

The next step was to make the arms, these I decided to make out of silicon, so first off I set about making the arms out of a waxed based clay, after a couple of attempts to sculpt the arms I realised I wasn’t going to achieve the uniformity I was after,

So with my thinking head on I struck upon the idea of turning the arm shape out of wood on my lathe, after gaining some success with this approach I then sanded and spray finished the turned shape before attaching a sculpted hand ready for molding (see images below).

Casting mould sides  (Sorry no pictures for this next stage) 

the next step I set the arm half way in the mould on a bed of ceramic buff grey clay and smoothed this around the arm to the half way mark that I had previously made on the arm shape then I made 2 round keying shapes in opposing corners next I poured the plaster.

Next day I removed the base panel and removed the damp grey clay, after cleaning up the mould side I waxed it before pouring the second sided with plaster, after another 24 hrs or so I removed the out side panels then slowly prized apart the mould sides.......PROBLEMS!  the plaster mould hade not released it self from the arm shape, on close inspection small fibres had been standing up inside the grooves of the arm and had keyed in these finer grooved details, also moisture had got in to the wood bloating the shape making it slight deformed.

Back to the drawing board!

I had been following several  variable transformers on ebay and had won one of the auctions......Large parcel arrives in the post.

This I hope will guard me against any bad flicker from the film lighting.
