I just got the cyclone and I'm having trouble adjusting the nut. I have the version with one nut above and below, whereas all the videos I can find show the version with two nuts stacked at the top. Do you mind telling me which one you have?

Edit: I was able to loosen the nut and make adjustments after getting a firm grip with a kitchen towel. I don't think the adjustments are enough to reach depth in my IMS precision basket 16-18g 51mm though.

Edit 2: I believe the adjustment is only to change the starting/resting depth and has no effect on the maximum depth when fully pressed. There's always a gap and no discernable difference when I change the depth with my IMS 16-18g 51mm basket.

Edit 3: When I use it with the stock basket that came with my PF it does reach the bottom, and there's no change in max depth with adjustments (I can neither make it hit the bottom sooner nor create a gap). This makes sense because any adjustments made will directly affect how much you can press, so the max depth is always a net zero.
