Things are coming together nicely now on the Ore Carrier.
A big head-scratcher is the teeny engine it has - it looks to me like one of those old syphon capsules that were around in the 70's to make your drinks fizzy, but the chances of tracking down a vintage one to check was pretty slim.
So i've gone my own way by sticking an EMA hemisphere of the right diameter onto a tube i found in the plumbing section of B&Q, and then the Saturn V engine bell on top.
The tube is just right but, alas, that plastic that no glue can touch.
So i've stuck the hemisphere on with Hot Glue.
There also seems to be a panel or something on the original tube and i've suggested that with a Go-Fasta Stripe.
