How many months and nobody realized that the rotor is going to hit the rotor housing if you remove the end plate and therefore remove the STATIONARY GEAR and then try to turn the engine?

No no no, it has to be a bent e-shaft or a warped rotor housings or something

And yeah... one piece seals need to be clearanced. Two piece Atkins seals also need to be clearanced.

i generally forget that as well, but then again i don't generally spin the rear rotor without the rear iron/stat gear in place...

but still doesn't explain why it binds up at one point with the engine fully assembled unless he hasn't torn the whole thing apart to figure it out.

not that i want to admit it, but i have had a corner seal pop out and get squished between the housing and iron once, so each 180* of rotation the motor would bind up(because the rotor tip was trying to push past the apex seal protruding into the housing at that one point). that is the closest i can come to an explanation for this.
