Yes, thats what is all about - 1:1 metal forming techniques in scale.
Well, the build is in 1:25. The EW was specially squised out to the size of it. Also I've got some pics on how to manage some larger "lower wheel anvils sets" on it.
I guess that should be clear from the pics.

Again "anvils" was simply mashinned like that. Dremel and a file on a nut.
Shitty, but still works...
