That's not why. I always try to build my stuff as close as possible to the real thing , that is reason why !
I just think that it makes no sense to build anything precisely to scale , we all know how we measure ten times or more to get everything right , and then just leave movable parts "welded together" ?
I'm not building toys I just try to build an exact replica of the real existing thing !
I hope you guys understand this answer right , I'm not trying to piss anyone off !
As Floyd says: MODELING IS FUN !
And now back to the workbench ...
