A rotor housing is a rotor housing is a rotor housing, but we seem to have an endless variety of names for the others, and yet we all seem to understand each other, so I'm wondering, what names do you use? I go for front end plate, centre plate, rear end plate myself, but I've also heard irons and side housings with every combination possible of front, rear, centre, intermediate, end. Also, how about you 20B owners? How do you make yourselves understood? Front intermadiate, first centre, number three side housing, I can't really think of a good name.

 

I call them all of those things depending on the context. For the 20B, I've heard them referred to as the front or "fat" intermediate/center plate and the rear center/intermediate plate.

As long as people know what you're talking about, you're fine.

 

For the 20B, there is also: thick intermediate plate, 80mm plate etc. I use several terms interchangeably.
