I remember using these plans for a school project. Incorporated them into a full safe. I ended up laser cutting the wheels out of 4mm acrylic I think, and made the casing acrylic too as it was supposed to be a child toy. Still had the loose wheel problem, although I didn't have the excuse of expanding wood. So strange to see someone else make it form the plans, as you never posted a video of it. Brings back so many memories of me trying to figure it all out. Great video.

I actually made a wooden safe based on your first lock article. I added additional shallow notches to the rotors as others suggested. to prevent the rotors from free wheeling, I added a small spring detent to the washers, which are fixed to shaft. works great!

So many clever techniques in barely 11 minutes. Thanks for sharing.

Matthias, I downloaded your design several years ago and made the lock. Just for giggles, but little did I know that it would come in handy. I recently purchased a couple of large safes that were locked open (Cheap price of $5). After lube them up, and removing the rear plates I was faced with the simple task of figuring out the combinations. Your design was essentially the same. One safe was worth $250 dollars. Thanks

It's so cool to see this again, as it was how I discovered your work back in 2008 as I replicated a simpler version for a school project, but I couldn't get it right because I couldn't find a video explaining it's construction. I guess I can rebuild it now, thanks for everything!

The wooden combinationlock was what brought me to your wonderful channel in the first time. I'm a big fan, keep up the great work Mattias!!

Considering the number of dust collectors you have, I never hear them in the videos. Love your stuff! Rewatch them often.

That original lock video is what brought me to this awesome youtube channel.

In 2014/2015 I saw pictures of this lock and a short video showing, how it works. I figured the plan out by myself and built it for a small safe, which I gave as a small gift to my best friend at his wedding. It was a nice project and I love your explanation!

Good morning, my virtual friend Matthias, I would like to congratulate you on your work, although I do not speak your language visually and I try to improve your work thanks for giving me a different view of woodworking

I built one of these for a geocache based on this video. Thanks Matthias! I added a section of a spring from a pop up sprinkler between the rotors to keep them from spinning. The spring fit over the dowel nicely.

Have you ever considered using a circle jig?

Only the very best in lumber security.

I love the way your brain works. Thanks for the video. About the wood swelling up thing. I had that problem with the steam/air engine I built from your plans. It had been laying out in my shop for quite a few years, my bad. The plans I downloaded from you were perfect. My shop is a little humid in summer. Thanks again for the video.

I built one of these a few months ago, it was an absolute blast of a build.

Matthias, you should have a home improvement show with all your videos. If its not called "Some Assembly Required" I'd be disappointed. Hell if you ever wanted to name your KZfaq Channel, it should be that!

Great video. I like how you showed how you build each piece. Very instructive.

This is awesome! Great works as usual Matthais!

Матиас.Я наблюдаю за твоими работами и делаю вывод,что ты просто технический извращенец.Конечно в хорошем смысле этого слова. Лайк конечно.

Nice to see that you're more comfortable promoting your plans these days :)

Mattias you are the best salesman friend.

Oh, Matthias. You don't need a combination to unlock my heart.

Very cool project. I plan on buying the plans to get the lasercut model. $7 is a steal. One interesting twist might be to have a magnet in each of the disks for a secondary secret panel unlocking, though you might need to have a 3 reed switches in series with a battery and a release mechanism. Love your work. Thanks.

Thanks for being you! I get so much out of everything you post. Stay awesome my friend!

Always fascinating. This is one reason I look forward to Fridays.

Work of a perfectionist,thrill to watch! You sir,should be proud of yourself,you're a legend!

just when i think you've done it all you do something else cool. i really enjoy your videos.

Lol, love the last comment about the bandsaw plans...

I can't believe it, I have been thinking about a wooden lock mechanism for the past few days!

i never do woodwork, last time i did it was 5 years ago but i love your videos matthias, keep it up!

Matthias has the best sales pitches.

...and this combination lock is great for teaching kids. If you don't have any kids, I'd be happy to sell you an instruction manual for making your own.

Every time I watch one of your videos, I wish I had a wood workshop. :)

Your working methods are impressive!

Matthias - sincerely love all the wonderful things you do - so, in the spirit of that, having seen where you're cutting on the table saw with the calipers there on the left - "Never leave anything on the table saw that you wouldn't want to be inserted in your forehead" is my rubric ...

I love your videos. Two suggestions: 1) spray adhesive for the patterns and 2) CA glue.

The high-speed sanding of the circles made me laugh for some reason. Wonderful build sir!

this is the project that enticed me to your channel

Greetings from the BIG SKY. Nice lock you made.

An excellent teaching aid for a future safecracker .

Mathias bringing the heat once again

Wouldn't a piece of felt be a practical friction generating device for this application?

Have you tried to pick it yet? Pretending you don't know the combination? Maybe holding light tension on the leaver and make it catch one of the grooves? Could be fun next video :)

Wow . You make the most amazing things in tree. Wish you a great weekend

what a cool dude. your videos are awesome matthias, keep up the good work!

"... but you also need a bandsaw." Best sales pitch ever!

Another great video! Thanks Matthias! I also watch Marius, he built your bandsaw, and has dropped your name a few times. ☺

your videos are so satisfying

This is awesome. I just discovered your channel. You've got yourself a new subscriber. Hope you can make more of theses in the future. I'm considering buying the plans.

Muchas gracias, acabo de adquirir los planos y realizare el proyecto con mi hijo, me encanto!!!! Muchas gracias nuevamente! saludos.

Nice lock, great video and as always great up sale opportunity. Looking forward to the next video, - Annie

What a good salesman, peaks our interest and then at the end "Oh by the way you'll need this band-saw" ;p

Goodnight Mr Matthias Wendel. Congratulations! As always, Mr. presents new and intelligent things. That God continue to bless you in a special way and getting better. I'm from Brasil I translate with Bing translator, so sorry for any errors.

You could try adding friction by making wooden splinter springs to press against the outside of the rotors slightly. But that is not necessary. Anyway I enjoyed the video, i was wondering whether you will show the build of that lock!

complicated for beginner, but i'm gonna give this a try, great design, thanks Edit: after watching several other videos, i think this might be the basic way to do it, so again, i'm gonna try this soon. I hope this can be done with basic tools Edit 1: so, i tried using chopstick instead of dowel, and it kinda not work as it supposed to, i'm gonna find some bigger alternative and retry tomorrow.

Your old video on the wooden combination lock is how I first discovered you.

"....more than happy to sell you those to" love that!

In response to felt location....it should be between the discs, circles of felt glued to your spacers . A thick enough felt would allow for expansion and contraction I would think, and still give some friction to your design. Thanks for the video, I'm currently building a homemade table saw based on your design, with a few of your suggested improvements as well as a few of my own.

I have always wondered how you get stuff done so fast now I know you have hyper speed nice job.

It makes me so excited to finish building my CNC! I could build one of these in a jiffy!

Neat work. For a Masterlock with a combination of A, B, C, there is a number X (which = 7 for a Masterlock) such that you can use an alternate combination of A - X, B + X/2, C. Rotations go in the opposite direction, so you go counter-clockwise first. The number X depends on the sizing of the lock's interior. So you need to find it by trial and error. I wonder if you could do that for this lock. For example, your combo is 27, 18, 28. With X = 7, the backwards combo would be 20, 21.5, 28.

Nice fun project :) You are not far from 1 million subscribers.... I hope you cross that line soon.

as a locksmith, this is the coolest thing!

My mother taught me how to cut out paper patterns and pin them to cloth and cut that, but I never thought of doing that to wood! 🤯

nice video

oh very nice work, thanks for your efforts!

finally. A lock that can stop sonic screw drivers. Take that Doctor

Love your channel, you're an amazing woodworker! By the way, are you an engineer by trade? I've only ever seen engineers use a compass the way you do.

2:15 This is so satisfying 🤩

That proud humoristic face at the end ;-)

A possible solution for wheels overspinning.... attach a stripe of sponge or a small brush in a way that applies a little friction on all wheelss. That wont be noticed much when spinning the combination knob and will surely stop the wheel right where you dialed it. :) thanks for your video.

27-18-28 was my high-school locker combo!!

Nice plug at the end!

the plans look great!

good video matthias. greetings from holland

the original combination lock video was the first video i watched by you

Your videos always fascinate me!!!

I like his low key subtle sense of humor. He reminds me of The comedian, Norm McDonald.

Put a spring on it, that would give you friction and allow expansion/contraction

nice project. When I make a notch with a round bottom I drill the radius then bandsaw the straights.

Love it! Thanks for sharing!

i love that you wanted to make a video so badly that you made the whole thing from scratch!

Put a piece of brush on the underside hidden between the tumblers and the dog (or whatever it's called) it will provide all the friction needed to stop them from overshooting.

An interesting approach to the locks.

Wow so amazing for all creation

Always love the high speed hammer sounds. :) Are you working on a new gig as pitch man? "I would be happy to sell you plans for that as well" I love your sense of humor and I always get a chuckle somewhere in your videos. Keep'm comin. Regards to Rachel and Olin.

The Master at work.

It's so satisfying watching you sand in high speed

Great work, This would be awesome to teach people how safe minulpation is done

This certainly unlocked my heart..

Matthias, each rotor has a small diameter washer glued to it, can you use a small thin piece of wood or metal like a spring, putting pressure tangentially on each washer? That could provide enough friction to stop the rotors from spinning freely. For the two outside rotors the other end of the spring is attached to the case, and for the middle rotor it is attached to the adjacent rotor so it clears under the tabs.

You could use a brush or similar which presses on the washers to create sufficient friction to prevent the overshooting.

To build the bandsaw, you need a drill press. But I refuse to make any plans for that!

I love Fridays always fun to see your clips. Question: How do you have time to be in the shop so much, I'm happy if I get 3-4 hours a week = o)

I want to make this so badly but dont have the tools what needed... Maybe i shall ask my teacher if i can do it in school where we have the tools and everything. I hope I can do it :) Btw nice vid! +1 Sub (First video I watch from u MADE MY DAY)

Great video, thanks for sharing!

its so satisfying to watch Damn!

Lock picking lawyer here. Rotate to the left. A little click rotate to the right and I'm in.

Interesting video to say the least and also I really enjoyed it. Doesn't your mind ever run out of things to make? God Bless my friend.

Regarding the friction, you could simply make three leaf springs that rub against each of the dials. and provide sufficient resistance.
