Thanks for the link. Looks amazing. Look forward to the progress pics on this oneBought from that website.
However...
...arghhhh! One screw missing
They have already replied to the email though to ask for our address to send out the missing bit, so good customer service so far!
I could build it up and leave the one out (one of four holding the cooling chamber to the frame), but the instructions are so firm on everything being lined up correctly and only barely lubed etc that I'd worry it wouldn't sit quite square without (not to mention the vibes when it's running). Anyway, I'm a grown up and can wait (that may be a lie...)
In the meantime, here's some nice stuff (dust will be eradicated before assembly...):
Most of the bits:
Flywheels (may get polished more before fitting):
Crankshaft (comes assembled, with strict warnings against fiddling as you'll never get it back straight/right):
Cooling chamber with one piston visible at the top and con-rod facing:
And from the other side, bore for the expansion piston; you can't quite see the samll hole that lets the air up into the top cooling chamber at the far end of the bore. There will be a piston attached to the threaded end of the con-rod:

Why did you have to go and post this? It's not like I need something like this, but now I've seen them I really want one (or maybe more). Pointless, frivolous maybe, but what fun.
Nobody 'needs' something like this. It's just pure, selfish want. Lots and lots of want! And yes I want one too!
