Setting MM2

Hi I just bought a monster mill MM2 and was wondering what everyone had the rollers set at. Was just wondering what was the best gap for efficiency. Also I am planning on running it with a cordless drill. I know you want to keep it as a slower speed, but wasnt sure what RPM was appropriate. I searched the forum but didnt find anything. Thanks for any input.

Thanks,
Dave

.038" seems popular. Slower the better...

Also, that better be a bad ass cordless drill. Needs a lot of torque to get that thing churning.

If it is difficult to start using any drill it isn't properly set. It is kinked. You have to make sure each side is set at the same gap. So GAO left then gap right.

I run around 150 to 200 rpm. My drill has a lock button on it and doing a quick guess of counting spins it's around there, about 3 times a second it turns.

I have a good milwaukee drill with a high torque setting. So it wont be a problem.

I'm a mechanic so I know all about setting the gap correctly. Thanks though.

Thanks everyone for the replies. As always much appreciated.

I set mine around .04 , but my little drill needs to get revved up to grind at this gap setting. Just need an excuse to buy a more powerful drill now.

Thanks for the clarification.

I have mine at .038 but I would suggest starting out at .04 since the knurling on the rollers is quite aggressive. IME my first 3-4 batches at .04 were great, then once the sharpness of the fresh knurling wore down I went down to .038.

Very good. That makes sense. Thanks for the reply.

I wasnt being a smart ass. I was just saying that I have experience in setting tolerances. Thanks for the info though I appreciate it.

I too used the factory preset on my MM2 for the first 5 or 6 brews then tightened it up just a bit (.38 i think, can't remember exactly though). As for drills, yeah, slower is better, around 200 rpms. If you don't already have a drill I'd suggest a corded drill with at least 9 amps. My 12 V cordless Dewalt couldn't handle it and I've gone through two cheapo corded drills so i finally spent some coin on a 10 amp Kobalt - that thing rocks. First time I've been able to consistently run at slow speed through the whole grain bill.
