I've got a Peter pugger for mixing scrap and making blends of clays. The pugger in not a de-airing, just a mixer. From this I take the fresh clay to the Bluebird de-aring pugger. If I use "Store bought" clay the de-airing Bluebird keeps me from having to wedge. The main thing about using clay from the Bluebird pugger is that I place the de-aired clay on the wheel lengthwise "------" then center, not vertically "!" to eliminate "S" cracks in my work. It changes the spiral orientation of the clay and keeps "S" cracks from forming.
Without the pugger I couldn't get enough work made to make a living in clay.
Forgive me if this sounds like a stupid question, but why run it through two machines? Does the Bluebird not mix the clay?
Also, when you say you put the pugged clay on the wheel "lengthwise -----" do you mean that it comes out of the pugger as ------ and you chop it up into little "logs" and put those on your wheel with the non-cut surface on the bat/wheelhead? Just curious - I don't have a pugmill, and unless I can find one that's stupidly cheap (i.e., free), I'm probably not getting one anytime soon because I just don't do the sort of volume some potters do.
