Jim - I just saw your post in the hop blocker thread. I think you are making it out to be much more complicated than it is. It is just a thin piece of sheet metal used to hold back the hops from the opening on the kettle. There's no way I could get you a picture of it "open". It doesn't open or close. That is a picture of the bottom of my kettle. Super simple to construct. I will try and get a picture of the hops collected behind the plate next time I brew - probably Wednesday.
On the B3 kettle the diverter plates are welded in as an option when you build your kettle. Mine has a couple small welds to connect it to the pick up tube, but could be constructed weldless.
Yeah, I have a tendency to make things more difficult than they are.
Tell me what you think of this idea...
Could I take a length of say heavy duty screen. It would only need to be 6-8" tall. Make it into a circle that won't open. After whirlpooling/settling, slowly drain wort by about half. Then, simply lower the circular screen into the kettle so that it would essentially surround the trub pile.
