Based on your photo, it looks like your gap is far too wide. For a finer crush regardless of mill, many are in the 0.025 to 0.05 range. It looks like you have yours at ~0.1-0.15. Suggest you use a credit card to calibrate.
What units is that graduated in? .45 inches you could drop a marble through. .45 mm would be less than half a credit card. Just doesn't make sense.
I suggest you forget the graduations and use a credit card until you can pick up a set of feeler gages.
I'm not trying to diss your mill, but, manufacturing tolerances and clearances being what they are, I would be astounded if the same setting on each end actually gives the same gap on each end. At any rate, test it before you trust it.
For what it's worth, I just mic'ed a credit card. It was 0.032 in. over the stock material, and 0.050 in. over the raised numbers.
I'm late to this thread but I bought a Pilot about 8 months ago and I've been struggling to find the right gap. I love the build quality (it's beautiful) but the gradations are useless. They must be for things other than barley. What can you crush with a .45" setting, nuts?
Anyways, lightly conditioning the grain and setting the gap to .03" with a guage seems to get me pretty good results.
One thought I've had is that the Pilot allows milling along the entire length of the rollers. As an experiment I"m going to use some painters tape to restrict the grain to only go through the middle 2-3 inches of the mill. Perhaps this will give me more consistent results.
