Step 1: How It Happened...

Picture of How It Happened...

It was built in 2012, the same year I started writing this instructable (because I'm clearly a bit of a slacker). But I'm happy to report that as of this writing (2014), it's been working great! The oak has aged nicely and we're all stocked up on cider. No "hard" cider yet, but we'll get around to it one of these days. [UPDATE: **brrrp** yeah... so the hard cider seems to be going okay now, too.]

So here's how it all started:

I have always subscribed to a theory I once heard on NPR’s “Car Talk” (R.I.P., Tom Magliozzi!) in which two people are far less capable of abandoning a silly idea than one person: “One person will only go so far out on a limb in his construction of deeply hypothetical structures, and will often end with a shrug or a raising of hands to indicate the dismissability of his particular take on a subject. With two people, the intricacies, the gives and takes, the wherefores and why-nots, can become a veritable pas-de-deux of breathtaking speculation, interwoven in such a way that apologies or gestures of doubt are rendered unnecessary.” -http://www.cartalk.com/content/andy-scale-0

During the apple season of 2012 John was over and we all got to talking about how many apples were on the tree in our backyard and what we were going to do about them and how cool would it be to have an apple press and we could probably crank one out it a weekend if we applied ourselves. Dammit.

So off we went, researching and doodling, collecting bits on my wife Dawn's shared Pinterest board. Eventually we whittled it all down to a plan in which I concentrated on the easy parts, while John set about building the parts that require knowledge and skill and real tools.

Step 2: Research, Design

Humans have been in the apple-squeezing business for centuries, so there was no reason to reinvent the wheel. Besides just looking at a bunch of web images of cool old machines, here are a few of the resources we used:

We "cherry-picked" our favorite features from the various versions out there, and there are endless ways to remix the various components: A bottle jack can be substituted for the big screw, for instance.

Among other lessons, we learned that grinding maximizes the juice better than blending or chopping or otherwise smooshing, and that stainless steel screw heads can really chew up an apple in a hurry.

Step 3: Materials

Picture of Materials

There are approximately four gazillion ways to build one of these so I'll leave it up to you to figure yours out, and will spare you the exact measurements. See, I'm sparing you, it's not like I just made that up as a flimsy justification for not measuring anything very carefully. Here's what we used:

- White and red oak. All of my design doodles were done with "pine" dimensions in mind: 2"x4", 2"x2", 4"x4".... but all that goes out the window when you're dealing with oak, because they don't pre-cut oak and other hardwoods to specific sizes like they do with soft wood - they sell it by the board foot. So I had to do some quick math at the lumber yard, and pick through the stock to find all the pieces I needed for the frame and hopper and tray. In the end, my 4"x4"s became 3"x3"s, and my 2"x2"s became 1"x1".

- Stainless steel nails. Big square-drive ones for the grinder, 1"x1/2" small ones for the frame and hopper, shorter ones for the barrel and base.

- Big giant screw from a bench vice, that had been unused in John's garage for decades.

- Carriage bolts to mount the vice.

- Aluminum stripping, for the "barrel."

About Oak:

We ran all the wood through John's jointer, which is really fun if you've never done it with hardwood: a grungy-looking chunk of wood goes in on one end, and a beautiful piece of artwork comes out the other end, the grain suddenly visible on an almost perfectly smooth surface.

John set to work building the barrel and the slatted drain that goes underneath it. These are basically a bunch of sticks with a trapezoidal cross-section: the barrel is made by corralling the sticks with aluminum bands, and the drain is a row of sticks held together with three bigger, non-trapezoidal sticks. The grinder wheel is a cylinder whose axle spins perfectly in its oak bushing, with just a little mineral oil to keep things sliding along.

While John was spinning oak into gold, I fumbled through my first experience making something with oak. As for building with it: Oak is really hard, and stainless steel nails are really soft. I drilled good pilot holes, soaped each screw... and still stripped the hell out of quite a few of them. So when you look at the parts I made, please do not look very closely.

Step 4: The Grinder

Picture of The Grinder

John's grinder wheel was one of the first things we were able to really play with as the frame was coming together. The hopper is removable, both for cleaning and so it can all be packed up smaller when the season is over. A small clamp provides a little insurance so the act of grinding doesn't pull the hopper off of the frame.

There are many versions of this that look very similar, so either great minds think alike or everyone is equally moronic. In any case, here's a fantastic apple grinder from WoodGears.ca, from Matthias Wandel, an absolute rock star with "and engineer's approach to woodworking." He has good detail here on the build of his grinder wheel: http://woodgears.ca/cider/apple_grinder. Our grinder doesn't have a lever pushing down on the apples like Matthias' grinder does, but I can see how that might be nice, particularly if you're going with a motorized wheel. It looks like the pattern of his screws might push the apples toward the middle of the grinder, which makes good sense. Our diagonal pattern results in a mini-drama in which some apples succumb immediately, while others find a spark of hope, and, buoyed aloft by their fallen comrades, they try to escape by heading to the right. But in what must be a grave disappointment for fans of apple-centric adventure tales, these brave rebels are invariably pinned against the wall and ground into oblivion.

Here is a video of the grinder in action, using a drill instead of the hand crank that we use now:

Step 5: The Grind

Picture of The Grind

The best way to show off all the pieces is to show them in action, so here's how we do it:

To sanitize, we spray all the surfaces with a diluted iodine solution and let that dry.

To maximize juice yield, we let the apples sit for a week or so.

A mix of sweet and tart apples usually tastes best, but I've never met a batch I didn't like.

The apples are cut in halves or quarters (otherwise they'd just roll around in the hopper!). We toss any brown gross bits in the compost, but minor blemishes on the fruit are no big deal.

A 5-gallon bucket sits under the hopper to catch the ground apples, held in place by a little wooden arm that swings out into position.

Then we fill up the hopper and start grinding!

A full pressing can be done when the bucket is about 3/4 full of pomace, which is close to 3.75 gallons. We've also found that letting the pomace sit for a few minutes before grinding provides slightly juicier results.

Step 6: Pomace

Picture of Pomace

(Note: we learned to do this part from WhizBang Cider)

About 20 pounds of fruit later, we're left with a bucket about 3/4 full of ground apples, or "Pomace." The pomace is placed into a container (the bottom 4 inches or so of a plastic bucket) which is lined with netting material. A "cheese" is made by tying the apples into a bundle.

That bundle is placed into the barrel or "pressing tub," then a disc made of cutting board material is placed on top.

That is repeated until four bundles have been stacked.

Step 7: Press

Picture of Press

The barrel, drain, and tray all slide under the screw, and a small sacrificial bit of oak (that has yet to be replaced as of the writing of this 'ible!) protects the pressing board from direct contact with the screw.

We place more netting on top of a bucket, secured with a giant rubber band, and slide that under the opening in the tray.

We spin the screw until it hits the board and slows down, then crank it a few more turns until the whole structure gives a little groan. Depending on how juicy the batch is, the cider starts pouring out immediately, and the first couple of gallons happens right away.

When the juice slows, we turn the handle another half turn, and continue that for at least 15 minutes. If there's not another round ready to squeeze we can extend this process for a couple of hours and still get another pint or so of additional cider, but if we're going through a big pile we'll call it done after the first squeezing.

Another option is to unscrew the press and give each cheese a shake to redistribute the pomace, then put it all back together and give it a second squeeze. Again, not a ton more comes out, but it can be worthwhile.

We get at least two gallons out of a pressing, sometimes more. And it's delicious. And who knows how many apples you're consuming when you knock back a glass of this stuff. Imagine how many doctors are being repelled!

Step 8: Cleanup

Picture of Cleanup

When the pomace has been fully squeezed, the cheese becomes a lightweight disk. What to do with that? Well, you can compost it, share it with your chickens and ducks, or do what Dawn does: make Apple Cider Vinegar. There are too many uses to list here, but she makes a ton of it each apple season. And this year she just ran out of last year's supply as this year's season started!

After a pressing (or a day of pressing), everything is hosed off (the ducks enjoy that), and left to dry.

Unfinished oak is naturally resistant to decay, and turns a charming gray color as it ages. A coat of mineral oil rubbed on all the surfaces helps keep it healthy for the winter.

This setup, including the buckets and the grinder, can all be nested inside its frame for storage.

It's all quite heavy, but if all the removable parts are removed, two people can move it easily. Or one person can stand inside it and hold the sides and waddle along looking silly, but still move it.

Step 9: Future Plans

Picture of Future Plans

Wheels would be nice. But to avoid a wobbly grinding and pressing experience, they'd have to either be removable or be able to swing out of the way to allow direct contact between the frame and the ground.

For storage I'd like to come up with a good cover, perhaps a modified barbecue cover or a tarp sewn into a giant envelope, that could close all the way around the press and keep the spiders out.

Grinder options: It would be fun to affix a bike gear to the axle of the grinder wheel, slap on a chain and figure out a way to pedal the grinder with a bike. John made the axle of the wheel removable, so the possibilities are endless... maybe we can hook it up to a stairmaster or a rowing machine or some other piece of exercise equipment?

Hard cider: so far we've managed to not make this work, mainly because we start a batch and get busy and forget to do the next step on the right day... but we'll get around to that. Meanwhile the "soft" stuff is fantastic! [UPDATE: **brrrp** yeah... so the hard cider seems to be going okay now, too.]

All in all this has been a great addition to the family, and I highly recommend building one of these to anyone with the inclination, and apples, and skill and real tools (or friends with skill and real tools).

Cheers!

Could you use the press for olive oil?

mikecraghead (author)isnalbania2017-09-21

Hi isnalbania,

My guess is yes, but I'm sure there are ways to optimize for that purpose. For example, we tried wine grapes with the same setup and found that lots of them survived unsquished, and had to be stirred and shuffled a lot to get to the juice. The point is, this works perfectly for apples and the basic mechanism is probably fine, but you'd need to dig a bit deeper and ask someone smarter than me if you want good non-apple results. Hope that helps. Cheers!

blksabbath (author)2014-11-06

Very nice instructable! I've made gallons and gallons of hard cider over the years, but always source the cider/juice. I have a couple of friends that had a motorized set-up using garbage disposal as the crusher...new and un-used of course. They've had great results.

mikecraghead (author)blksabbath2014-11-07

Ah, hard cider: we'll get there! We looked at garbage disposals but settled on the wheel for a couple of reasons: a disposal would mean making a purchase, and I generally work to avoid such behavior. Also it would need to be of a high enough quality so that it could grind a pile without overheating, which would eliminate the cheaper units, wouldn't it? But yes: I've seen disposals integrated quite nicely into cider production!

Update: we're there, and it's awesome.

bunnycop made it! (author)2016-09-12

complete!!! added legs and a hinged top for easy loading, thanks again

mikecraghead (author)bunnycop2016-09-12

Very nice!

Thanks for the idea, will put it to work this weekend

bunnycop (author)bunnycop2016-09-07

we are going to be pressing this weekend i will post a few pics, thanks again for the great build!

mikecraghead (author)bunnycop2016-09-06

Beautiful! Enjoy!

Teodor2014M (author)2015-03-02

what happens if you put barley in the machine?

mikecraghead (author)Teodor2014M2015-03-31

Hi Teodor2014M!
My guess is: major barley spillage. I don't doubt that the wheel could be adapted to process non-apple items, but I think the tilted-screws-in-the-wheel setup is pretty apple-specific.
Thank you!

Tecwyn Twmffat (author)2015-01-25

Looks like a great machine but ...... Errrrrr ....... I see a nice looking cat but no plans?

danvilleman (author)2015-01-15

Great but the one I made does not use trapezoidal wood slats on the side. Don't see the need for it, 1x2 oak worked fine. Since the narrowest part of the vertical is on the inside there is no advantage to having that gap open wider as you go to the outside. Just takes longer to build. The one problem I did have was in the 1x2 verticals tending to twist left or right thru repeated use. I use mine to squeeze tough old honeycomb.

mikecraghead (author)danvilleman2015-01-15

Hi Danvilleman,
I like the drill-vs-jack solution! Clearly gets the job done.
The trapezoidal slats are worth the time because the narrowest part is on the outside not the inside, so the very narrow gap is facing the apples and only juice and no pomace escapes. The taper means that you can more easily reach the surfaces from the outside for cleaning.
Cheers!

danvilleman (author)mikecraghead2015-01-15

I just spray it down with the garden hose to clean. It has less of a taper but cleaning is not much of a problem. I went with cheaper wood but boiled it in beeswax for 20 minutes, then let it cool. One year in the weather exposed and no noticible changes.

loren1964 (author)2014-11-24

very good instructions thanks for taking the time to share this with us

Waisie (author)2014-11-17

Amazing. Thanks for the share.

dr_peru (author)2014-11-06

Two thinks I like combined in one project: alcohol and woodworking - you definitly have my vote :)

mikecraghead (author)dr_peru2014-11-07

Don't drink and drill, bro.

Leo the Apple Supervisor clearly worked extremely hard, look how tired he is by the end. Apple supervising is hard work.

Awesome job on the build as well :)

True, true. Imagine how unruly the apples would become without supervision!

nmcrae1 (author)2014-11-06

Great job - just what I've been looking for - I've been a wine-maker for years and have tried several ways to make wine from Crabapples, with no success. This should be the ticket!

I've also heard that freezing the apples, then thawing them will increase your yield - as it helps break down the cell walls and release more juice. It might work with the press to get a little more juice!

mikecraghead (author)nmcrae12014-11-07

We don't get huge temperature swings, but we did have a box of apples on the back porch during a rare freeze, and you're right about the yield: not a dramatic increase, but noticeable. The only problem with letting them sit a week or two and a freeze/thaw cycle is the delay: there are a couple of weeks when the season is in full swing and we're drowning in apples, and making cider in self-defense so we aren't buried alive!

jo'neil2 (author)2014-11-06

You did great, elegant and efficient design and implementation!

A minor suggestion regarding your sacrificial oak block: I built a press 15-20 years ago (not elegant but it works) and, instead of the sacrificial block I drilled a hole, a little larger diameter than the screw, part way through the block, sat a steel washer the same diameter as the screw in the drilled dimple thus letting the screw turn against the washer, not against the wood. The same block is still serviceable.

mikecraghead (author)jo'neil22014-11-07

Great suggestion! The current block is wearing thin, I'll definitely add a washer to the replacement. Thanks!

KirstieLynn (author)2014-11-07

Great Instructable! Looks like a really fun project!

LynxSys (author)2014-11-07

A wonderfully functional and very attractive project. Thanks for sharing it! If want to add wheels, Google "retractable casters". You'll find plenty of shop-made and commercially available sets of wheels that can be flipped down only when you need to move the press.

krissyv (author)2014-11-07

This is an amazing instruct able. Thanks for sharing!

Xcalibur (author)2014-11-06

Great job on this! It was very enjoyable to read and makes me want to start plans of my own... Step 1: Plant more apple trees. :)

Beekeeper (author)2014-11-06

Very good project but I've moved and all my apple trees are at my previous house!! I wondered if the wooden parts might be soaked in a hot beeswax + mineral oil mixture to prevent the acid juice soaking into the wood. This may prevent the oak going black.

TreeMunky (author)2014-11-06

Amazing, I'm building a press myself, I feel a redesign coming on :) Many thanks for instructable.

(because I'm clearly a bit of a slacker) this tends to happen when you enjoy the goodness of the orchard ;)

billbillt (author)2014-11-06

Leo is a very cool supervisor!~....

The Awesome Inventor (author)2014-11-05

It would be a cool idea to make a desktop version for work or school if you seriously needed some apple juice!!

The Awesome Inventor (author)2014-11-05

Awesome!! Cider for everyone!! :D

rimar2000 (author)2014-11-05

Excellent work! Like your humour.

rimar2000 (author)2014-11-05

Excellent work! Like your humour.

momsnacher (author)2014-11-05

I love this! my girl wanted to make one last apple season. I think I'm going to have to go to it in a couple weeks. I've got tons of scrap hardwood pieces just waiting for something like this.

wilgubeast (author)2014-11-05

I'm very pleased to see the quality of apple supervision demonstrated by Leo in your Instructable.

Beyond that, the humor papered over any gaps in craftsmanship (of which there were less than you indicated), and this was a wonderful read. Thanks for including so many external references for making a cider press.

We'd love to see the apple cider vinegar ible if it gets documented...
