More 3 D Printing
Whilst my orders for earlier work are underway, I have done a bit more drawing and have now drafted up some lamps for the signals; as below:
I have also managed to sort out a drawing that I did some time ago for a water column. The larger of the models for 3 D printing need to be hollowed out (to save on the printing medium, which is charged for by its volume). This took some time to get right, as I had multiple different parts I was working on.
So these have also be sent of to Shapeways for printing. As before, I will use the lamps as masters for lost wax casting (another new trick to learn!) but the water column will be used as a master for some resin casting (the old dog really is going for lots of new tricks) – it will also need an etch for its operating arm.
However, lets see how good they come back first – as I think I am probably counting chickens prematurely here……….
