Hey Muzza, I have seen Bman put a clamp in between the neck and bridge pup cavities then think he hangs the clamp with wire.
I use another method of shaping the hanger to fit in the neck pup cavity and drive a wedge shape piece of wood in the back and one in the bottom of the neck pup cavity works well but still not sturdy enough to put the hanger in a vice to work on.

@ Michael, sorry to hijack your thread. Uluru red will look great. Black pickguard will work better than white. Good luck with the sanding when you find time
