Hans, when you get it finished and running, I suspect I'm not the
only one who'd enjoy a video clip of the thing in action
Thanks Peter. You are right, I should say steam engine ( it's the
ten second flash to bang I suffer from )
Actually this is my second one. I have a bigger one that I finished
last month that runs. ( surprisingly ) With that one I only faceted
the sugalite piston and I held true to the concept that everything
must be made out of stone. The rest of the stone parts are carved and
With the CZ one I have made the sliding parts ( piston and shafts)
out of 14ct gold. And here the focus is firstly to get it running and
then to see, after all the components are faceted, the play of light
that the facets ( hopefully ) will create.
why bore the cylinder right through a pair of glue joints?
Simply because I want to push the envelope, Brian.
That stone was marked for faceting in the conventional way, but the
rough just happened to be in the wrong place at the right time.
I use Hxtal resin to bond the stones together, and the joint is
actually stronger than the CZ material itself.
(I have deliberately broken a few pieces before, to test the
strength of my laminated stones.)
Also the pressures are not high, typically from 10 to 20 pounds on a
small machine, so I don't think it will split.
And it looks cool!
