CNC lid! nice. I am with you Hank.

+2 on the machined catch jar lid, though it's nothing pressing. I also think a lid or plug of some sort for the hopper would be nice to prevent stray bits from wandering out while traveling. Maybe something like this (but bigger and with a slit in it) could be made to work, and as a bonus you could use it to rest the jar on while grinding.

How about just one of these?

One word to describe the LIDO - Elegant
At least from the design standpoint, the LIDO is on another level compared to the Pharos. Starting with the removable two position handle, it's embossed with a custom made die. The little knob fits the overall appearance, not too small or too big. Chrome plated cap nuts on the top, circular designed functional cut outs that please the eye and feed the beans perfectly. The same cut-outs below help feed the beans into the burrs; the plastic bean tube fits the hand just right with a plate above to keep it from slipping. Effortless to turn and easy to adjust!

Another fine example from the minimalist OE design workshop. "Form follows function"

Mine arrived today. What a beautiful little machine. This is my first hand grinder of any sort. I used 21g of CCC Baroida SO for 350ml of water, 2 turns CCW, and an espro press. Steeped for 4 minutes. I was a bit surprised that the coffee was so cloudy. It was also quite bitter. Really not great. I need to work on the grind and brewing clearly, but man the grinder is so fun to use. Well done OE.

#037 arrived in Ontario today... with a cracked catch jar lid

At the zero point, the burrs don't seem to be centred correctly. As I turn it, there is a rubbing noise during a portion of the rotation. I assume that's not right. Is this something I can fix during re-assembly with a new jar lid?

Chris, tough luck about the cracked jar lid. At least now Doug can stop blaming the Texas postal system for breaking them. It sounds like whatever broke the lid was strong enough to affect the burr alignment. Watch Doug's video on LIDO alignment when you put it back together and that should clear up the burr rub.

This jar lid thing is a real puzzler. Yesterday I tried to break one...bending, flexing, squashing in a vice, and all I can think of is that it is somehow temperature related since the plastic is totally impossible to break at least at room temperature. To make that lid I use a die press and die and the temp out in the workspace can be as low as 50F...the top surface is slightly cupped so it flexes when pressed....I am just thinking out loud here since there must be something I am doing to create some weakness in the lid as it seems impossible for the postal services to break the lid without breaking the jar...Currently I build these things in monastic silence to try to hear some little pop or crick sound when I put on the lid and tighten the bolts/nuts.

On that rub....that is why we set up zero, in many ways to try to avoid going into the entire thesis of grinder burrs that exploded on the Pharos alignment issues. To begin, if you tighten the burr setting on your K10 toward zero while running you will eventually get the burrs close enough to grrrrrr them and you immediately back off the setting. The burr rub is only at one spot but since it is spinning relative fast you don't get any more feedback than a grrrrrr sound. The burrs do not touch at all 360 degrees around the radius, just one area on first contact and with a hand grinder one can witness this same thing, but since you can turn the burr so slow instead of grrrrr you hear/feel a rub at one part and instead of just carrying on as with a spinning electric grinder one can go down a rabbit hole of obsessing about alignment. That is a conversation we had hoped to avoid, at least for a while.

I adjusted the Lido a little finer almost to the 1/4 mark and 40 seconds later cranked out about 13.5 grams of Sumatra from D' Amico roasters.

I used only one pull on the pavoni this time (I often screw up multiple pulls short changing myself of the best pull) it was about an ounce if not a tiny bit less a ristretto, if those be better shots on the Pavoni Europiccolla then I'll deal with it.

Well I have to say this one nailed it. My straight shot tasted like Sumatra coffee and not some roast only profile. Needless to say I drank that without any sugar (all of it) but mixed with milk. I like cappucinos what can I say, but this stuff tasted sweet straight so I could have drank it either way.

Mixed with milk and no sugar it was a Sumatra flavored dark chocolate bomb. Yes you can absolutely (at least I can) tell if the espresso is pulled good even in milk drinks. They come out much richer and flavorful when so.

This grinder is another true espresso craftsman's high value poor man's hand cranking coffee making tool by OE. I am thankful there is someone out there who deals in quality coffee products for frills free people who want to excell in their culinary arts but normally can't afford to.

I could definitely see it being temperature related in some way. There is no obvious damage to the box or grinder. Is there any reason why the part has to be plastic, rather than metal?

Is it normal to get the rubbing at the zero you originally set? 1/4 turn and it is gone. I've brewed a few cups, and it seems to be grinding okay.
