Somethings are sent to try us.
Thought it was time to check the fit of the cranes, now I've made a hinge.
As you can see, they don't fit, they should drop onto the crutch, obviously they don't.
If you look at the 2nd pic you can see why, the brass jibs aren't the same as the plastic ones, by a considerable amount.
You can buy the etched brass in two lots, the first is "railings and cranes", the second is "other stuff"
such as radar, lots of surface detail, most of it not needed and other bits and bobs.
The first lot is a stand alone set, so if you don't want to go to town, it will be fine. However, the little brass bracket come with the second lot so you can fall into the trap as I have just done.
I find this annoying, these things aren't cheap. I think we have a right to expect some sort of quality control.
Good job it's only a hobby.
