But yeah, this is why I don't like using 2 mounts for projector and lens Vs the shelf style mount I created where it keeps everything aligned regardless of the projector.

The solution is to mount the new PJ so it's lens is in the center of the screen.
So a shelf allows moving the projector and keeping the CineSlide/ISCOIIIL combo to remain as is.
I'll likely get and adjustable (up / down) shelf that is wide enough to move the projector around.
Any thoughts on shelf type?
Pic of JVC RS20 enclosed.
Looks like off center.
Chief mounted to ceiling.
There is a Chief->RS520 adaptor plate.
Don't think I can move the Chief mount without a major re-work.
Easiest would be a shelf.
I enclosed a diff pic that shows more detail of mount.
Build a shelf on column behind projector to better align the CineSlide and ISCOIIIL.
(for prior help and to see if you are still out there).
