- You don't need a CNC to benefit from using CAD. Using paper templates to cut out the parts exactly the way I needed them. Also used the templates to precisely position the dowel holes to mate the parts.

Plans for this bandsaw: woodgears.ca/big_bandsaw/plans26 - แนวปฏิบัติและการใช้ชีวิต
I could watch Mattias build bandsaws all day.
Hell, I built one of his 18" ones and all my friends and family treated me like I was a genius.
In reality, the drawings are so well done it would be difficult to screw it up. but man, was it a lot of work.
its good to have you back Mattias.
Matthias.
The H might be slightly silent, but it is not forgotten.
All these bandsaw vids are getting me nostalgic
Stay tuned, Coming to a Screen Near You!
The Land of Bandsaws...
Lol :-P
LLAP
I’m never going to make my own bandsaw, but I love watching a craftsman at work.
I was thinking. "Damn I would totally glue that backwards" then you almost glued it backwards. Its nice you don't edit out your mistakes
asymmetric dowel pattern to the rescue!
Update on my build of the 20", Got my table on last night trunnions were done last week it's pretty cool to be building one at the same time. I'm very happy with it so far next job is properly securing the motor and sanding the frame before the enclosure is made
Why do I like this guy so much? Perhaps his no nonsense approach and lack of rambling on and on and on.
Hey guys! Welcome back to the worlds largest home made wooden ban saw build. In today's episode we are going to be building the trunnion that will allow us to tilt the table top of the saw. Did you know that trunnions were first used for cannons so they could aim at different angles? Well this is going to be an explosive episode so I'm asking all you little wood chips to comment, like and subscribe and don't forget to hit that bell to catch each and every episode!
I’ve asked myself the same. The answer is that he’s not trying to be anything. He’s just a simple guy showing us how to do amazing shit.
Check out keithstestgarage
These videos are giving me a serious case of nostalgia. The good stuff. Top shelf.
Although I've never made trunnions per se, I have cut concave and convex curves. My results weren't exactly uniform, smooth and without bumps/divots. Maybe because I don't have a bandsaw nor horizontal belt sander.
Nonetheless, hats off to you Matthias for your ability to saw and sand for a great fit!! Hopefully I'll be successful when I make your bandsaw.
Man, I can't believe you can freehand engineer like this. I would lose my mind trying to fit everything together and making it work without a complete plan. You're amazing.
Sounds like an important meeting is taking place in the backround.
You're like a machinist gone to the woodworking side!
Love your precision work. Calms my OCD watching you build with wood.
I’m really enjoying seeing this come together
It is relieving to know that even experts like you still make stupid little mistakes that I do all the time. Makes me feel like I'm not as dumb as I thought. Thanks for keeping it in the video. Keep up the good work, your videos are inspirational!
I get a kick out of the fact that he's using the bandsaw to help build the bandsaw
Matthias is a catalyst for bandsaw replication.
You should see people with 3d printers
yea if you have a metal lathe you can build all most and others on i was told and your widest imagination would allow you to build something yea
It takes a crane to build a crane...
@@rpavlik1 shut the front door
man your videos are so good. I love bandsaws and the idea of making your own as big as you'd like is just amazing to me. I wish I had the time to take on this project myself!
You make it look amazingly simple - even with an occasional, brief misstep. Thanks for the video.
Truly wish I could subscribe over and over and like as many times as I want only because just feel like once dont show how cool this guy is
Pretty impressive work, Matthias! 😃
It's looking better and better!
Stay safe there with your family! 🖖😊
Have a drink every time Matthias says trunnions
Excellent video. That table looks good with the nice trim around it. And it's so familiar, almost screwing up a glue-up :)
I love that you share the mistakes along with everything. We are all human.
Awesome work!
Come back in ten years for Matthias's: 'Building a 72" Bandsaw"
I think that's 720" badsaw. I reality I think he'd probably top out at around 60" due to the available with of Baltic birch. For axles I think I would seriously look at either trailer axles or spindles off of what ever model car one picks in the boneyard
You are AMAZING! Love your videos!!!
Wonderful work.
I was just watching one of your previous bandsaw trunnion videos a few hours ago, you had the exact same glue up issue haha. You mentioned it may have been a better idea to glue it first, and then drill and add the dowels after.
It was fun to watch!, thanks for sharing that!
I'm early for once. This is making me think about building a bigger bansaw, haha. I built the 14 inch bandsawmill a few years ago and its been serving me very well ever since. Especially with a 3 hp motor.
About glues: For dowels, just a half drop per dowel is enough. It would destroy the wood to try and take them out! For threading soft wood, metal inserts are best, but "CA hardening" is also great. Drill, tap, apply 1-2 drops of thin CA glue in the threads, wait a minute, then re-tap. I have never had CA hardened threads fail!
The best part of every machine build is when you start using the machine to build itself.
Buildception!
I love these bandsaw Videos
I need a band saw. It's one of the things that stops me from making more stuff in my woodshop. As I see these come together I can't help but want to try it myself.
Using the bandsaw to make things for the bandsaw. Love it
Its so weird how one day I'll watch a video of this lad from 2011, and the other I might see him from 5 hours ago. He is brilliant now, was brilliant before, and will probably be brilliant later.
Matthias is like "hmm, this tool isn't just quite how I want it. imma just make one exactly how I want it from the bottom up" Ur videos are amazing and I can't stop watching
Good classic Matthias video. Thank you!
You are wonderful, enjoy watching, always Sincerely yours
Very Nice!!! I have never seen that before!!! Thank You!!!😃👍😎
Thx for the trunnions explanation. Didn't know that
i just enjoy your video, your skill is beyond mine :D. Awesome
J AIME BEAUCOUP SE QUE TU FAIT BRAVO
I love how you get so much use out of that homemade paring knife!
You are AMAZING !!!
gracias por sus videos
Why do I watch this video? I know I will never build a bandsaw....but there is something satisfying about watching everything go together...
Good stuff. You may already know this, but... If you want an easier way to check alignment of dowel holes instead of using the solid dowel, you can make "alignment dowels" by using the same size dowel and cut a kerf say 55% into the dowel from one end and then another at 90° to the first in the other end. The kerf makes them very easy to remove. (And just keep them with dowels and they're always accessible.) Thanks for the video, amazing progress. Cheers, David
Not worth it for one time use. Cause years from now with the same problem, I would not be able to find them regardless.
great work
You should create some merch such as a t shirt showing your bandsaw evolution
It’s a good thing you work fast when you had the oops!
nice work,
I only hope that when you are finished with this project, you will build a BANDSAW! ;)
Mathias is the only channel I am subscribed to, that ended a live chat with in 30 minutes just when he had 1000 viewers and climbing. lol Ive seen other channels that cant get 1000 viewers in a chat room. I found that to be kinda interesting.
Oh, I wasn't even looking at the live numbers.
@@matthiaswandel Lol,,I just happen to notice,,it started with very few,,but grew quickly!!! Just then you had some lighting issues and ended it.
I love the word "trunnion." That is all.
Especially when it's made of bubinga.
It is a delightful word! I need to file it away in my memory - right beside "vibraslap"...
Do not ignore "escutcheon".
@@VideoNOLA I had to get Uncle Google to school me on the pronunciation of that beauty!
I've been sitting here saying trunnion in my head for minutes, however, now it has to share its time in there with bubinga
LOL
Your a genius man
Matthias loves a good trunnion.
Those trunnions seem like a great job for the pantorouter.
I don't know if the reach of the pantorouter is wide enough to do it in one setup.
Does anyone have an opinion?
Are these trunnions the same size as his other bandsaw? If so I'll buy those and see what I can do.
Any thoughts would be appreciated. Thank you.
Love those bloopers. :D
I won't be satisfied until I see at least ten bandsaw builds.
I guess after you tighten the knob, there's so much friction in the trunnions, it makes them very solid. If the fit isn't perfect, will they wear into one another for that fit over time?
Given enough time, they would wear into each other, but I think it would take decades or centuries. Part of what works so well is the size of the trunnion. The bigger the radius, the easier it is to approximate a perfect curve. Trying to make a one inch radius trunnion would be next to impossible by hand.
One thing to stay away from is having the inner trunnion (is this the correct term?) be too small a radius for the outer trunnion. When you tighten it down the table will still rock back and forth because the stability of the trunnion comes from the outer ends of the radius. Make it to size or a hair too large, and the flex in the wood when clamped will provide a good grip.
I don’t know what trunnions are. But here I am.
Oh those seem very useful.
Those are some nice 2D printed templates
I figured on this one you would do countersunk through bolts instead of dowels. I'm sure you have your reasons.
For bandsaw #6 Matthias will be renting one or two of the Bays in the Vehicle Ammebly Building at KSC
I'd love to hear why you like making your own large tools like band saws. There's obviously the "It's fun" factor, along with it just being content for youtube, both of which being more than enough reason, but I have to wonder things like: is it much cheaper? And how does that factor in with your time? Is the end result better than something you'd buy at a store, or perhaps not objectively better, but more suited to you? I don't think you *need* a reason to do something like this, but if you have reasons I'd love to hear what your thought process is.
large bandsaws are very expensive. And impossible to get into a basement.
@ Matthias Wandel
6:12 do you wish you would have taken the piece to the bandsaw and cut off the tips of those pegs sticking out to make them shorter to account for the dried glue mishap? maybe you could half them and not lose too much strength? just as an adaptation on the fly i mean. Thanks!
good job,,, Indonesia Present you chanel
nice
Would it be possible to add a brush on the wheels to prevent sawdust from accumulating between them and the blades?
Great job. I was just thinking. Any update on Amogla camp. Has it been sold yet ?
"Do as I say, not as I do"? After assembling the table support beam for the 20" bandsaw, you said it would be much better to first glue the trunnions and only drill the dowel holes and insert the dowels after everything is fixed initially...I did it that way and it was much more relaxed than in this video ;-)
I wanted to hide the dowels, so I couldn't just drill through everything.
Okay, fair point. I didn't care much about the appearance of a part of a machine that's hidden under the table anyway...
What will intrigue me,is the micro adjustments that needs to adjusted because expansion, wood expands more sufficient than metal at certain high and low temperature, wood also absorb moisture, and cause warp,are there anything to prevent a minimum distortion
I wonder if "sliding glue" is an issue or an obsticle you just learned to navigate around? I always seem to get railroaded by that every time.. Perfect cuts, lines match, 90 degree angle, lazer guided jig... aaaand the glue slides. Or even better; screw hits a grain and shift everythings a little to the left and; 92,9 degrees, lines are off, jig is now up for the fire pit and the table have 4 legs with different lengths.
Mattia which program do you use to design your projects
So super hit
Now, did you lubricate the wood?
edit: silly me, of course not
Good to see the dry fit on the dowel joints this time round =^.^=
Spoke too soon, hopefully you'll have gap free trunnions on bandsaw #6
Dowels with no dowel centers. Neat! I remember you saying that you picked up CAD in order to make plans for your website audience. Would you say that CAD enabled this technique, or would you generate a template some other way?
Could have used a paper template and flipped it, I suppose.
Any videos on inserts vs CA reinforced wood threads?
Very good.How do you weld the belt-saw?
How long until Matthias builds some behemoth of a bandsaw that solves the door problem by disassembling into two parts?
Thanks for leaving the screwups in your videos.
...It seem I always have a few on every project.
I've come to think that mastery is the ability to avoid AND recover from screwups.
I think that Baltic birch is the biggest piece of "new wood" I've ever seen you use!
First watch the video. Are you hunting for likes?
@@moninum yes, my self esteem tanks unless I get them.
Jesus, that bandsaw IS huge.
Matthias, have you considered building a large wooden vice? In some moments there it seemed like one would have been of help, say, when you're hammering two pieces together instead of pressing them like you usually do, but your steel vices are too small for that job.
Trunnions are my favorite snack.
Awesome
Trunnions again? Man, when are we going to see you make a ship saw?
ooh, trunnions are what they use in film for the geared tripod heads that you turn with wheels
You should copy Colin Knecht's trick for dowels- he keeps a few that are slightly sanded down so they can be used for fitment but removed easily. He marks his with colored felt marker so he knows to save them for future use.
I don't dowel things often enough to have a set of each diameter and length
For Bandsaw #7: Matthias will build a Ships Saw! :-) :-)
I think last time you said that you would drill the dowels thru the trunion part into the beam to avoid alignment problems next time.
yes, but I didn't want to have the dowels visible from the front.
Please make a video on diy vise
Matthias, I built a saw with 18"X1.75" wheels but I can't get it to track. My blade is 1". Planning to resaw from sawmill. I reviewed some of your "wheel" vids to no avail. Any advice?
Make sure the wheels are coplanar and the wheels have the crown in the middle. You do have a crown on the wheels, right? Without one, blade won't track.
@@matthiaswandel have crown still travels... how much crown on a 1.75" wide wheel?
will you build a dust collector for this one?
won't need one.
Do you think it’s necessary to loosen the tendon on bandsaw blades when not in use?
No.
@@matthiaswandel Thank you. Keep the awesome videos coming 👍🏻
HOLA ¿ cual es el costo de los planos ?
So if you compare the guesstimated price of your self-made bandsaws, how do they compare to commercial products? Love watching your videos BTW.
The cost is the sum of what I paid for materials. Which has no relation to what your costs would be, because that can vary a lot based on what it costs where you are, how you shop, and what you already have. Same goes for buying a bandsaw.
Working hours should also be factored in, but having a finished product that one has built oneself to one's own wishes is priceless. Looking forward to the next video!
Go price a 20 inch bandsaw. Or any size larger than 14 inches, really. You will see that it can be tough to convince yourself that it would be worth it unless you build it yourself (and the prospect of building it yourself appeals to you...).
Did I hear you say FIFTH BANDSAW BUILD?
. . . was there a mention of the cause of (or need for) the thumb "tourniquet"?
I cut it on a sharp edge on the drill press belt cover while changing the belt.
Out of plain old curiosity, why did you choose to use a softwood block to mount the trunnions to?
probably because thats what he had laying around
Any advice on how to avoid the nasty chipout seen around the 4:30 mark?
when drilling a hole with a forsner bit, drill it all the way in one pass instead of out and in again.
