I have feeler gauges, but I just end up using 0.88mm guitar picks most of the time.
Just a fyi I just did the conversion as the gap on the mill is usually done in inches so, that said a .88mm guitar pick equates to a .35" gap which is it seems where most people are tuning to.

I'm using Dunlop Tortex (green) picks, BTW. If I need to adjust my gap I cinch down on a pick kind of tight, so I'm thinking I'm at about 0.034. I'll spot check my mill every few months if I think of it, or if I am trying to troubleshoot an efficiency issue. Otherwise I'm pretty much in the "set it and forget it" camp.

And I'm tuning to C# standard on my 6-string and either B-standard or drop-A on my 7 :)

ohhhh boy someone is playing something heavy !!!!! I play as well Ithink I may have said that above I have a degree in classical guitar studies. I'm into metal as well but never really down tuned more than D and with my 7 always left it in B...... other guitar buddies of mine into grindcore etc their strings are like slop on the neck it's insane they can even play the guitar !!

That sort of poor attitude will keep you in intermediate brewer status forever, Denny.

The attitude is in the beer, Chumley.

I have no idea what my mill is set to and I don't care.  As long as I get the crush I want it doesn't matter.

hey as a side note .... I posted a thread !! ( this goes back to our PM's on the other forum )

Good on ya!

I read you said recently that it was something like .028.

My gap is set to .032. I normally get around 75%, not great, but it's pretty consistent, so that's all that matters. I typically use some rice hulls in my mash as well, just a couple hands full. Using a bazooka screen, it tends to gum up sometimes.

If I said that, I must have been drunk.  I've never measured the gap.

It's as if he's afraid he might learn something.

I actively and proudly maintain my ignorance!

this si a funny thread.  I have my MM-3 at .028.  At least last time a measured and adjusted it.  Endosperm good and crushed, and most husks still intact.  Who could ask for anything better

Barley Crusher says the factory set at .039. Crush looks good but I guess I should check it since I added and electric motor to power it.

Hopfully I am past my 1st Kit !

Seems as if you might've been drunk when you posted these few comments! haha

Interesting. It is all about lautering and not having stuck sparge.
I have my MM-3 at .40. I get about 85 to 88% efficiency.

Unfortunately I agree but also strongly disagree with your assessment..... yes absolutely sparge time and accurate sparge temps and length are very important. I can't imagine anyone saying crush is not a important factor in your mash efficiency. Just by the fact that more surface area is exposed by a finer crush alone will increase the % of mash eff alone regardless of sparge period though a proper sparge be it fly or batch is very important don't misunderstand what I am saying. I mean there is a reason that people struggle with that balance between stuck sparge and fine crush it's because they know the yield is higher from the finer crush but it can be problematic as well, if I had to guess if you are getting a 85-88% eff it has a lot to do with your PH as well as very stable temps as well as what Iassume is a verrryyy long sparge. Just my .02 but also many years of brewing as well as going to school specifically to brew backs up my statement as well.

I'm hitting 80% efficiency at the factory setting with a 10 lb. grain bill.  Efficiency drops to the low 70s when the grain bill gets up to around 15 lbs. or so.

I don't really see the point in tightening the gap any further.

Agreed with all answers even the one I disagreed with ( if that makes any sense ) : ) if your system is getting the efficiency you are looking for and it's working don't change it. I only started this thread out of curiosity as well as to see what others are getting for eff at certain gap settings. As they say if it isn't broken don't fix it. In my particular and this is only my observation when I had a tight crush I was hitting 85-86% mash eff but I got lazy and didn't keep up with checking my gap. it spread and my indicator was a lower than average eff so I checked and readjusted..... after adjusting I was back at 85% eff so I know in my case the crush effects the mash efficiency and I also btw do a 1 hour sparge sometimes a bit quicker at 45 minutes and have gone as long as 2 hours but that was because I had problems with pumpkin. Beware the pumpkin. anyways I appreciate everyone's input. cheers !!!
