Hi Denny, I use a Grainfather. What's your question?
The question is how the hell do you seat the top and bottom plates when the silicone rings keep slipping off! I've gotten some suggestions to try.
Ah yes, it's not the easiest. The bottom plate I put in place without the pipe attached to it. I hold it oriented vertically, and push it down until it reaches the bottom, and then slowly and carefully twist it until it's in place. It took me a good few goes to it right. The top plate I do the same thing, but when you've added the grain, the flour that sticks to the side makes it a lot easier than the bottom plate.
Fitting the bottom plate definitely seems to get easier once the GF has been used.
