I assume that you used the photos from the AHB forum? I did, but I did it differently. Instead of drilling a single hole and then using the lug nuts to adjust the crush gap, I drilled a series of holes on the knob that allows me to adjust the crush gap between all the way open to grinding flour.
When I have mine all the way open, it hardly crushes the grain at all, and I'd suggest that this is what is causing your efficiency problems. On mine, I normally crush two holes finer than that fully open hole, which is narrower that the recommended 60 thousandths of an inch I think (prolly more like 40). At this crush gap the sparge is significantly slower, but hopefully more efficient.
I understand that Coopers crush so fine that they get over 100% efficiency (compared to the lab efficiency) which is pretty impressive! They must be producing very fine flour.
