Quote from: "Dean"There was no apparent tachometer present, but the last time I had the good fortune to observe your milling operation in full-swing the sweat rolling off your brow would indicate an estimated steady 60 -75 RPM.

I think I came in at the tail end of it, looked more like 30 rpm to me...  :banana:

Quotethe foul look on your face clearly indicated a drop in the aforementioned rate

This alone is the only tachometer home brewers need:

Face of concentration - > Max RPMs (~150-200)
Foul, exhausted look -> Min RPMs (~50-75)

Scale to current rpm level dependent on progress of hopelessness on millers face,  +/- X% where x is the perspiration level :P

lol!

I guess a quick calculation of the outer speed of the 250mm rollers at 400rpm would allow me to calculate the actual rpm required for the little rollers in my setup.  Thanks for pointing that out richard.  my crush would have been too fast.
I'm still going to setup an electric motor and pullies to do the job.

Looks right - I fear the math for the scale is a bit complicated though, I suspect the Face of concentration, lets call it mu, and the foul exhausted look, lets call it beta, are inversely and exponentially related. Further, I suspect there is a coefficient of brewing desire expressed as a factor of X above which is pivotal to the entire equation - a quadratic I'm guessing?

ugh ...quadratic ....flashback ...make the bad man stop!

of course there's another possible variable in there too ...that being the number of smartasses present and offering advice?

Gil Breau

Don't forget the beer ingested beforehand!

The sad thing is, all the extra variables are all negatively inducing ones...lol

fakr: I think if you follow through with that logic you'll actually end up with a speed even faster than 400RPM... 10 inch diameter would be 31inch-ish circumference, so 400RPM would be 12400 inch/minute - the equivalent on a 2-inch (6.2-ish inch circumference) roller would be 2000RPM :P

Gosh, my biggest concern is to make sure I don't flip the crusher and spill the grains all over the floor when I'm crushing. If I can dough-in without incident, I'm happy!

I was there the day Richard spread your grain out on the floor and demonstrated the procedure   :banana:

Richard

:oops:

It's ok; when Jake brought my splits over he did the same to one of my bags - karma, eh ;)

hahaha ..I almost did it to myself too - those bags are thin

the funniest part at Jake's was a few minutes later when the vacuum showed up with the message "Jake's girlfriend says to give this to Richard"

I actually used a rolling pin to crush my grain once :roll:

I really hope that was only for partial mash/specialty grains :P
