Giving a robot a chainsaw, this is the beginning of the end!... Very cool, I'm always impressed with your blend of every aspect of production and craft woodworking
I finished my apprenticeship in 1984. since then there have been more and more joinery centers. Nice to see the old carpenter's work again. Greetings from Schaumburg Germany. OK, at 1.55 I was a bit scared! Funny.
Love this channel. I always see some new (even though might be decades old) tool like the one at 1:16 - chain mortiser. And it's mixed up with manual work, or regular power tools and even CNC robots. Liked before watching.
Much with the innovative as always. Robot chainsaw mortising for the terrifying win. Trimming all those pins looks like a frankly painful process. Hats off to those with patience to create excellence.
The process engineering in all of your videos is amazing. I know it probably wouldn’t make for a good video but it is super fascinating to think about.
I love seeing that you guys are always hard at work, especially in these tough times, it's super encouraging and really nice to see that your seamless and devoted work has obviously been noticed and noted. Keep up the great work as always, I can't wait to see how this will turn out!
Thank you very much. :D We do our best although I must admit seeing all that's happening, I fear 2021 will be hardest year so far.. But we will get through it..
CNC Robot chainsaw?? Are you kidding me?! That's awesome! I challenge you to do a 3d sculpture with it as a fun time project :) Great vid and music as always!
Is the size of the thrusses for visuals / architectual thing is somwhere really that much snowload on the roofs 😀 in Finland thrusses ususlly are 2x4 or2x6 material and placed 900mm apart 😀
steel pins for plates do not seem to have any mushrooming to hold in place, is this simply a friction fit? Where will this be installed? Curious about building code and how the pins are covered by code.
Geesus. That's er different. Perhaps train second robot to catch the shaving from the first... but awesome stuff. Were those pins interference on the plates or the timber. I would imagine they would walk with changes in humidity if not careful.
Are the steel pins only pressed in ? Or is there any other way to secure them? So it's not like you're clamping on to the steel plates and therefore loading the pins with a sheer stress , right ? If so, are the any measures to load all pins equally ? how do you program the robot ?
I model in rhinoceros with rhinocam plug in. For krl files I use Irbcam software. The pins are only pressed in, The holes radius are 0.1mm smaller than pins so friction holds them in place. The pins are calculated to sheer stress and they transfer the stress more or less equally because of the small tolerances and precise hole drilling. The wood also gives a little so to speak so if one pin is much more loaded than the others, small deformation in wood around that pin leads to more load transfer to other pins in the joint until all of them are loaded.
Good engineering eye! It is a very long story but to put it short, structure is more than strong enough to be assembled like this but there is a hallway somewhere around the middle of the span and there are two other support posts for each truss hidden in the hallway walls which will be assembled later on. They will redistribute the forces.
I always learn something from watching your videos. As in the chain saw at the end of the robot arm. Is that an option for this Bot or did you make it yourself? I always thought that nothing goes through wood more efficiently than a sharp chainsaw. The trick is controlling it.
The spindle holder and chainsaw holder are home made, also the bases robots sit on :D Now when I see the chainsaw on a robot works, It opens so much possibilities ..
Nothing for a couple of months and then in two days, two people write the same comment, amazing!😁 In short, structure is more than strong enough to be assembled like this but there is a hallway somewhere around the middle of the span and there are two other support posts for each truss hidden in the hallway walls which will be assembled later on. They will redistribute the forces and serve more purposes. Some of the steel post will be left visible and will also hold the big sliders for huge glass panels which will slide and divide space along the trusses.
Nice use of the saw as a morticing attachment. Is that a kuka? Coincidentally im thinking of buying a used one, slightly worried about setup and my ability to learn how to program it😬 please tell me it's easier than I think it will be
My first thought was: that's a strange place to be adding hydraulic fluid. Then I realized it was bar oil for a chain saw and knew: this is going to be good. Curious as to why the CNC (or other fancy tool) wasn't used to make the slots at 4:01. I've made a lot of those like that, and getting the bottom flat/parallel/etc is always a pain -- even if the chisel _is_ sharp.
Glad you like the chainsaw:) the reason is length, we would lose more time getting those beams to the robot than just doing it by hand. Workshop space is becoming more and more of and issue and that's why sometimes we have to rent a bigger workshop space like in this case..
@@lignumchannel Sused, rađe puni lamelirac od rešetke. Statistička pogreška kod rešetki od drva povećava se s brojem elemenata u krovu. Nešto bolje kod lameliraca nego kod tesane ali sve jedno.
This guy has a cnc chainsaw where else are you gonna see that
beautiful work man
:D Thank you man!
all hail the cnc chainsaw!

ahaha :D Thank you very much!
CNC chainsaw! Never seen that before, so cool.
First time I tried it! :D
Chamfer bit? Naaah
Roundover bit? Naaah
Spiral up-cut bit? Naaah
Chainsaw “bit”? Awwwww yeah!!!
👍🏻🙏🏻
:D

Its so nice to have all the right tools for the job. Poetry in motion!
I'm glad you like it! Never enough tools.. :D
Ovo je posao mojih snova! Ovo bih mogao raditi do mirovine. Odlicno odrađeno, bravo.
Hvala puno Kopriva!:)
You guys have it dialed in. Putting all those amazing tools to work. Love the custom chainsaw attachment. Smart bunch of guys over at lignum.
Thank you very much Nicolas! :D

Thank you very much Matias! Glad you like it! :D
Crazy, Crazy, Crazy Strong Trussess. Now Thats Build Quality!!
Glad you like it!
your channel has become of my favorites and I always look forward to your next build
So glad to hear it! Thank you very much! :D

Yep, my father and lathe worker Damir had the steel nerves, I know I'd go crazy making 4000 of those.. Glad you like the robochainsaw! :D
The process engineering in all of your videos is amazing. I know it probably wouldn’t make for a good video but it is super fascinating to think about.
I'm thinking lately about starting making other kind of videos than just production from start to finish.. We will see how it goes..
Very impressive. I would imagine those joints with the embedded steel ties are super strong . Superb quality work . Love the chain saw on the Kuka
Thank you very much! Yes they are super strong, and probably a bit overkill..
I love seeing that you guys are always hard at work, especially in these tough times, it's super encouraging and really nice to see that your seamless and devoted work has obviously been noticed and noted. Keep up the great work as always, I can't wait to see how this will turn out!

Wow I didn’t realize the scale of the project from the thumbnail.
I got very excited when I see how big the truss is gonna be!
Wow, how cool is that. A chainsaw on a Kuka, I love ❤️
Glad you like it Sergio!🙂
My mind is blown on so many levels... CNC chainsaw!!!
😁glad you like it!
A CNC chainsaw. What!!!! Brilliant.
Glad you like it John!
Such an innovative connecting system. I'm impressed!
Sweet! Looks like it's a cool, big project you've got going on! Can't wait to see part 2 :D
Thank you Matt! I hope the final assembly will be done in a 3 weeks period..
How many meters is the span of the wooden truss
Those robots are amazing
Glad you like them Al!🙂
One of my favorite channels. Thanks
Wow, thanks a lot Mitch! :D
just what I expected - on time , and it works great -.
Chain saw on robot arm, near Halloween. No scary dreams with that :)
Thank you for such a lovely vid, waiting for part II.
Thank you, Coming soon!:D
Nothing like a robot wielding a chainsaw! Great job on your videos.
Thank you very much!:)
I really liked your chainsaw robotic arm of the dead. If the machines were to take over humanity this would be the final boss
His reach and mobility is bad though.. But If I put some wheels on it, you could be on to something.. :D
good luck for the next 18! looks great so far!
10 done atm😁 Thank you Ellie!
Wow... so impressive! Super!
Motorna testera kao glodalo i CNC motorna testera.
Pa to nigde nisam video, svaka čast. Pozdrav
Hvala!🙂
Absolute work of art!
Thank you Veek Leek! :)
boy o boy, everything to a grand scale. Awesome,,,,,
Thank you very much Dan!
CNC Robot chainsaw?? Are you kidding me?! That's awesome!
I challenge you to do a 3d sculpture with it as a fun time project :)
Great vid and music as always!
That would be a cool project, I think I should give it a shot one day.. 🙂
That’s what I call The Art
Thats some very cool stuff right there
Is the size of the thrusses for visuals / architectual thing is somwhere really that much snowload on the roofs 😀 in Finland thrusses ususlly are 2x4 or2x6 material and placed 900mm apart 😀
chainsaw attachment hands down stole the show , that is alot of engineering & incredible work .... why did they choose wood instead of steel though ?
Aesthetics mostly.. glad you like it!
steel pins for plates do not seem to have any mushrooming to hold in place, is this simply a friction fit? Where will this be installed? Curious about building code and how the pins are covered by code.
Wow! Its a massive project.
Again big magic!))
Big thanks:D
You stated the span, but what is the spacing? You are using meters, so are they 1m apart? Looks like that roof would support a tank.
very neat
Thank you!
Cool video. You folks have the best robots. Mahalo for sharing!🐒
Thank you very much for watching! :D
Close to Posthuman carpentry. The future is always already happening somewhere else. Great video btw..subscribing
All Amazing. Thanks for sharing.
Thank you for watching!🙂
Bravissimi fate sempre lavori di altissima qualità,complimenti 💪💪💪

Dear Lignum, let me be very honest with you! There is one, and only one thing I do not like about your videos - they are too damn short! ;-)
With all the time it takes me to edit I'm amazed they are so long :D
@@lignumchannel - Hollywood rule #1: leave 'em wanting more.
Yes just 5 minute.... Too damn short man....
No speech and few videos have ever been spoiled by brevity.
Nice giant jig saw
That's a work of art man!
Thank you man! :D
I have cnc machines but not a robotic arm. Where does one land one of those?
Machineseeker :D
What do you do with all the saw dust?
We have a briquette press and we make briquettes.
@@lignumchannel great!
Wow. A chainsaw on a robot. Talk about Terminator.
how about building a chain morticer onto your robot
Yup, shouldn't be a problem :D
Nice! What kind of weight is one truss?
I'm not sure exactly but I would say around 600 kg with steel..
@@lignumchannel Thanks. Looking forward to Pt 2!
That's a big job.
Yes, I think the biggest this year so far..
Офигительно ! Круто !
How do you frame a shed?
Nice video. I used to program robots. A robot with a chainsaw is a bit scary. 🙄Saw one with a 2 foot diameter saw blade on it once😅
Are the steel pins only pressed in ? Or is there any other way to secure them?
So it's not like you're clamping on to the steel plates and therefore loading the pins with a sheer stress , right ?
If so, are the any measures to load all pins equally ?

@@lignumchannel Wish I could get such on point answers from my profs
Thx a lot
Who sharpens the chainsaw it looks like they do a great job.
Since wood is cheaper there? or else steel is a better choice and easier to make!
Awsome solutions. That sthill chainsaw in the robot arm! did you make that? What model is that Kuka?
@lignum - diagonal web members are in tension but connection with top/bottom chord is done as if there are in compression or amI missing something?
Good engineering eye!

CNC chainsaw, now I've seen it all.
Great video. Thank you
Glad you liked it!
Wow that's a lot of work ! Cool to see the pins being made ! Why didn't you use an electric chainsaw ?
Thank you renaud! It is electric, that was just oil used to lubricate the chain:)
@@lignumchannel my bad ! Very cool ! Did you do the engineering of the truss ?
I thougt small warehouse, 18 more to go suprized me. Tell something about work. Which is the project? That a really awesome ceiling
What a beauty :)
Thank you!
If you'd thought to use a gas chainsaw instead of electric you could have the fun of programming the robot to refuel and mess with the carburettor!

Hey, awsome work!!! Just out of curiosity for your great chainsaw bit. What software are you using for your cnc robot? Greetings Tom
Please tell me the entire crew helps sweep up at the end of the day?
Damn impressive 👍
Thank you Jack!
Watched a video you made 3 years ago of an arch. It was beautiful. Is there a way to make one side look like a real log doing that?
Nice video but are you sure that orientation of tension struts is right?!?
Would like to see that structural calculation :)
Nothing for a couple of months and then in two days, two people write the same comment, amazing!😁 In short, structure is more than strong enough to be assembled like this but there is a hallway somewhere around the middle of the span and there are two other support posts for each truss hidden in the hallway walls which will be assembled later on.

Hi i rly like your work. Ty fo sharing. Can i ask wich model of kuka robots did you useing ??? Ty for answer
Odlično ili bolje rečeno PRELEPO!
Pozdrav iz komšiluka!
Hvala puno!
Haha never thought that you can use a chainsaw as a CNC bit :D
Where do you get your timber?
wonder the price of these
Master! I just wonder where did you learn all this stuff. By look you are around 30.
I wish I could work for you.
well, a lot of mistakes is my secret.. :D You almost guessed it, I'm 32.. If the business continue to grow, who knows!
Is this a Double Howe?
What is the span of this truss beam
12.2 meters
Well done comrads
у меня не получается так же быстро, подскажите как
How do you dial in a robot chainsaw?
It takes some time to make the blade plane perpendicular to the spindle but but other than that, same as any other milling bit..
@@lignumchannel I see. Thanks for the reply.
Very cool!!!

Good used ones are up for sale for arround 5k €..
Cnc chainsaw? Now i've seen it all
I have a couple of more ideas:)
