Thanks Sneezles61 - my return for recirculation is an infusion pipe centered in the mash vertically, and has a quick-disconnect fitting at the keggle return connector so I can connect and disconnect easily. Should not be a PITA, at least I hope not.
My process would be to mill the grain into the basket, then hoist/lower it into the adjusted and heated mash water (currently I start with distilled water and modify it for the type of beer I am making). The tap water in Las Vegas does not taste good. The grain will be milled somewhere between coarse and medium, but not very fine....I need to zero in on this with some trial runs. I'll check the pH and for dough balls and adjust/stir if necessary, then connect the infusion pipe and start the recirculation. I'll put the lid on the keggle and monitor mash temperature, adding heat with the propane burner as required. I'll check the pH during the mash and tweak that if necessary. When the mash is done I'll remove the infusion pipe, and raise the basket and press it and allow it to drain into the keggle as I start the burner to heat up to a boil. When it has drained I'll hoist and rotate the basket out of the way. Then I'll put a hop basket in the wort and proceed with hop additions when the wort is boiling. If I see that my wort is very cloudy with trub (I expect it will be because the grain basket will have 800 micron mesh), I'll recirculate as the wort heats up, without the infusion pipe in place, so that some of the trub is collected in the hop basket. The hop basket will have a finer mesh (probably 400 micron, I am still thinking that over) and should catch trub that the grain basket did not. I think I will order a relatively large volume hop basket, still thinking about that too. I have not ever done this method but that is my plan, and I'll adjust it as I learn my setup's strengths and weaknesses. I've tried to make this easier for brew day, and at the same time produce quality beer. We will see. I keep reminding myself it is the journey, not the destination, but I'm trying to make it both haha.
