Mill Gap Settings
« on: December 24, 2015, 10:16:16 PM »
I'm looking to close the gap a bit on my mill but I don't have feeler gauges. Can anyone tell me what household items may suffice to measure a certain gap? I would think a credit card would be a specific gap that would work. Thanks!

Credit card is a bit thicker than .040

Anything flat will suffice as long as you can use it to be sure the gap is even. You could fold up paper even. The number only matters if you adjust frequently and want to be able to reset easily at 0.0XX

A credit card will get you close.

This mill is set to .045", I'm looking to get closer to .040 or .035. Looks like credit cards are .030.

I use four standard business cards. You can use two sets on either side of the mill to make sure it's even all the way across.  Works good so far.

The credit card thicknesses are changing with the roll-out of "chip & pin".  The new cards are much thicker than your old Visa/MC was.

Just something to keep in mind going forward.

My grain mill (BrewTek) has dimples on the round things that are rotated to adjust the setting and a diagram that shows what location of the dimples is what setting. While not as accurate as feeler gauges it's worked for me.

Why not just adjust based on the crush?

My mill is difficult to adjust. Sight turns on the knob move the gap a lot (relatively speaking). If I try to adjust by eye balling the gap I think I would waste my time loosening when I want to tighten, etc. So I use a feeler gauge to ensure the gap moves the direction I want it to go.

Guess so.  People seem more worried about gaps than crush.

Of course they are because the "gap" largely dictates the "crush", and when adjustments needs to be made you can't dial your mill to a certain "crush level" but you can dial to a specific "gap distance" between rollers. One serves as a sort of measure for the other.

Otherwise, we'd just recommend that the OP set his mill for the "optimal crush" and he'd be all set. :D
