Herb Grinders

[Lift Innovations]

About a year ago I had GAS. I got several grinders.
Finest grind? My free S&B grinders I received with purchase of the Mighty and the capsule loading device.
My favorite grinder? Lift -with the fine sifter.
I like the cavities you put your material in so I don't have to squish the top end to push pins through buds to connect to the lower end like you do with all of my other grinders. I like the 1/4 turn threads so I'm not unscrewing for 3 or 4 revolutions to open the device. I have another grinder, a custom made Phonecian, that also has the 1/4 turn threads. I don't think I'll buy another grinder that does not have this. I will say the Lift version of 1/4 turn is better than the Phonecian version of that feature.
My material is easier to grind than with my traditional grinders. By this I mean it feels easier to turn through dense nuggets than the traditional grinder.
I own and have given away several grinders. This is the only one I bought two of and now probably three of because I'll likely convince myself I need the red one.

Thanks for the kind words, we spent about half of the development time on the threads and a butt load of prototypes to make them work properly - it was worth it in the end. It's the future we don't have hover cars like we thought we would, so we should at least have threads that work on our grinders. (Note to self, make a hover-grinder)

Well crap now I need a lift grinder also. I was thinking it might be harder to turn also because physics (like how a fan blade moves faster toward the outside of the blade but is also easiest to stop there).

You are correct, the blade does travel a farther distance (and at a higher speed) to the outside of the blade as compared to towards the centre (that how we spell centre in Canadian BTW eh!). This does require more torque. But because we have 3 stationary blades and 4 rotating blades (which cut progressively like scissors), only one blade is cutting only a few millimeters of material at any one time. The surface area of the cut is 25 to 100 times less than a conventional grinder. This greatly reduces the input torque required. Our cutting system is bi-directional so it works in any direction and cuts 12 times in one rotation. Also having the heavy spinner, it acts as a flywheel that dampens the already minor torque pulses.

100 times less would be.............0?

100 times less would be.............0?

I mentioned that our grinder cuts a few millimeters at a time.......lets say 2 mm so 25 to 100 times surface area would be 2 x 25mm to 3 x100mm = 50mm (about 2 inches) to 2 x100mm = 200mm (about 8 inches)

Sorry I put the mm after the multiplier instead of the distance - my bad!

Those prices are to me in America. No idea what they are in Europe shipped, but I know vapewellness in the UK has them for 9 pounds, so there could be other options in Europe for cheaper.

Well, 3 hours have passed and I have something totally different to post, soooo... mods feel free to merge.











It’s biodegradable, but there are levels of biodegradable, so...


Now i’m going to soak it in water to see if it dissolves. Because science.

really nice man ! No doubts about the quality, its a santa cruz shredder, I remember when they came out first(the metal ones) they were one of the best quality grinders to find back then.
According to their support, they recommend using iso on a q tip. I would like to make it rather simple and put iso in it and leave it in ultrasonic cleaner for few minutes, since the q tip leaves the cotton hairs behind. or put iso in it and grind few times then rinse it with water and dry. Im wondering if any cleaning would work out. Im glad that you are enjoying it mate

Since we're on the topic, I'll chime in with my year or so experience with this grinder. My last grinder was a Spacecase which I noticed the aluminium teeth were starting to chip (I even spoke about it here before). I did my research and found that the Lift Grinder used stainless steel parts, and no way of metal teeth smacking into eachother for one reason or another. Since I bought it I never had to replace a part, but they did send me out a free updated part when I had asked them about it, so it's nice knowing I wont be left out on upgrades.

The type of grind I get depends on the many variables of the green I put in. I try to keep my herb at 58% humidity, and this grinder cuts it with ease. It may not be the finest grind, but it does keep it nice and fluffy. I like that it treats the herb delicately as it cuts, which I find preserves the smell/taste better than my previous grinders.

This is some Gushers using the small sifting disc:

This is the kief collector after around a week of betw .5 to 1 gram a day using the stock mesh screen. Im satisfied with it and find that you get what you put in:

This is the cutting chamber which I havent cleaned for 6 months:

The only real grime that builds up is around the top rim and the steel blade. I dont find that any of this interferes with its effectiveness, but I oughta clean it soon just to keep it pretty. Overall, I am pretty satisfied with this grinder; it was an investment that was worth it to me knowing I wont ever have to replace it (although I am grateful I got in at the original price).

We've been thinking about making a finishing disc and blade option for a bit, been getting quite a bit of requests for it. Hopefully soon.

Welcome to the forum. Is it not as simple as making a sifting disc with even smaller holes? I'd jump on that.

Hey Loving that the grinder has been serving you well! Thanks for supporting us in the beginning.
For the Ultra-fine disc, we could make a disc with just smaller holes - but I know that won't be good enough. We want to get it right and to do that we're going to have to do some changes like playing around with the rotating blade thickness - to decrease the clearance between the rotating blade and the stationary blades and the sifting disc. We have about 1.5 mm clearance right now which works for the three discs we have now. But We'll probably need to decrease it to about .8 to 1 mm for a proper Ultra-fine grind. When we do that we'll have to modify the shaft to accept the thicker blade. We also want to try different serrated patterns on the blade. We'll also spend some time testing different sized holes in the sifting disc. It's probably an over 100 hr project to do everything like modify the models, make some prototypes, do some testing, get rid of the test material, have some snacks, do a few iterations, make the final models, make the shop drawings, get the production parts made and verified, make some product labels, enter it all into the store and inventory system..... It's something that we'll be doing, just need a bit of time to free up.

Very cool, interested in what you guys come up with!

You should probably add an extra few hours for more snacks. That’s a lot of work for only 1 snack break.

It'll be 90 hour of snacking and 10 hours of working!

This is the cutting chamber which I havent cleaned for 6 months:

That picture perplexes me.

One of the points that is always made about this grinder is that you're only cutting through one of those three chambers with one of the blades at a time, with the point that only one blade cutting through one of the three chambers at a time is part of what makes it easier to turn.

However, in that pic, there are two cutting blades cutting near the central region of two of the chambers at the same time, with a third blade that's beginning to cut through the third chamber. This doesn't follow. Was this one a beta tester model before they updated the design or something, or did I just completely misunderstand the original claim?

Thanks, It's not that complicated - just finding the time right now is hard.

Imgur doesn’t work here, so all we see is a blank box. Postimage or tiny pic both work well.

Imgur works for me, I just open the pic in a new separate tab and copy / paste that link.

Yes it does actually. I misunderstood how the "scissor" cutting worked. I had it in my head that the rotating blade-arm was one sid of the scissor-blade, and the other cutting blade was the edge of the holes in the grind-plate below it.

I see now that the rotating blade is cutting against the side of the chamber above it.
Makes sense now. I was wrong. All (or, at least one thing) is right in the world again.

Thanks

You're welcome. Thanks Stu for getting the Image to work.

Great googly moogly... that’s crazy...

I probably need that. I’ve never ground more than an 8th at a time, but I still probably need that.

 

[arb]

I definitely need that.

 

[Ramahs]

It'll never get used, but I still need it.

A cheap one I just came across. Looks nice aesthetically. No idea of function but it looks like it should perform like the standard plastic grinders.
