rotate then scale components problem

[REACHMEAQE66]

so i thought this would be easy to fix but I cant find an answer.

I have a quarter arch which I use 2 x to create a whole arch by just rotating and moving one of the quarters. I put these in a new component to preserve editability and modularity but then that modularity kicks my butt when I want to scale the arch. have a look at the issue below. Al i want to do is scale the arch as one object. any ideas?

If you just scale one of the instances of the arch, and if you position them with Joints, it will work as I think you want it to.  But, having the model would help us help you.
