So i just sold a couple things last weekend on Craigslist, and i finally bought a barley crusher, (which i've wanted for way too long). and when i got paid yesterday, my wife let me buy my first 50# sack of pale malt as well. The barley crusher instructions say that the gap is set at .039 thousands of an inch. my question is this. Since i've never milled my own, what would be a good gap to start? or does barley vary enough in size that you adjust yours frequently? Like so many other brewers on this amazing HBT forum, i always want to try to do things perfect the first time.

I would try it as is and see what your efficiency is. This way you will have a base line which to judge from. I would also get a feeler gage and see what the actual gap is verus the listed gap. When I bought mine the gap was preset .035.
Next:Smoked Pilsner.
Primary:Belgian Red, American Stout w/Roeselare
On Tap:Pale Ale, English Bitter
Aging: Imperial Oatmeal Stout on Vanilla beans.

I rather owe you a dollar than cheat you out of it.."Dad"

I set mine at .032, which happens to be the thickness of a credit card.

+1 on .032. I get 80% batch sparging. Get a feeler gauge. Mine came set at the marks and it was .035, not .039 like the factory says. Congrats.

I just got mine as well. Tightened the gap a bit (~1 O'clock / 11 O'clock) and ended up at close to 86% eff. Overshot my OG by about 10 points, but I also had alot more boil-off than my last session too (first winter batch in CO).
