Hi all,

So I just got a Porlex mini hand grinder for my Aeropress and have been playing around with it. I also just found the English translation of the manual and something is worrying me but I don't know if it's just teething pains or something. I haven't ground any coffee yet but when I crank it it is incredibly squeaky. Is this normal? The manual says that if the grinder makes any strange sound you should stop immediately.

Just looking for some insight from anybody else who has one of these little doodads. Thanks for your time.

Hand grinders usually squeak at one of two places: 1. handle knob or 2. upper bearing.

An easy way to eliminate the squeaking is to get some mineral—ideally, a food-safe version—and put a drop where the pin goes through the handle knob and another where the burr axle exits the top of the grinder housing. That should fix any squeaking.

There are 101 uses for mineral oil around the house. It's great for cleaning stainless surfaces, for example, or for conditioning cutting boards. It's sold at pharmacies as a laxative or baby oil. It's also sold at hardware stores. The products sold at the pharmacy are more likely to be food-safe.

Hey thanks for the advice.

I'm familiar with mineral oil as I use it as a base for sword and knife cleaning oil. The squeak has greatly reduced after I ground some beans but I will take it apart when I clean it and see if it needs a dab of oil. Much appreciated.

My mini doesn't squeak, but I can coax the knob into squeaking a little if I twist it the right way.
But Eastsideloco is right, it's probably either that or the bushing.

My LIDO squeaks sometimes too and in that case it's the top bushing. A tiny dribble of oil takes care of it for a good while.

Make sure your oil (food safe) does not interupt the taste of your coffee.

Opt for a odorless,colorless and also tasteless one.

The squeak is now non existent after a good week of roughly 2 grinds a day. I guess it needed a good breaking in. Now it's time to take this little guy apart for a good clean me thinks. Thanks again for all the advice and info.
