Making the blade guides for my big bandsaw. These are the same design as the ones I made for my 20" bandsaw back in 2016. woodgears.ca/bi... Plans for this bandsaw: woodgears.ca/b...
I'm currently building your 20" bandsaw and last night I got it powered for the first time it was very rewarding and is running great. I too haven't actually balanced the wheels yet but they seemed pretty well balanced just on there own bearings. I also did the same thing threading the bolt in for the upper guide block but I added some glue too. Love watching your videos!
On end grain tap threading after drilling a slightly smaller hole I use Hot Stuff (CA) and spread it all around in the hole with a BBQ stick. Let it setup and re-drill the hole to ream out excess then tap. This for me makes the threading hold and last for a longer time. Cool Band saw build by the way !
I will always love Matthias. I found his Woodgears website first back in like 2012 then when I realized it was the same guy making RUclips videos I was super excited. Thanks for the videos! Don't ever quit.
10:15, shaking in reference to having a stand or not, you might want to look into trebuchets on wheels. I think what you're seeing is related to the concept that trebuchet designers use when adding wheels to their systems. I wish I could explain more but I was tricked into taking chemistry instead of physics in high school. :D
I really like the way you engineer the grips for your guide adjustment arms, very sturdy and secure. You make it look so simple, but I am sure you took several hours to get there... I watched your guide for Big Bandsaw Guides and see how much time you spent thinking about these details. Great reference!
Matthias, I've been watching your videos for years and I love them. FYI, I have absolutely no intention of ever making any of this stuff.Keep up the good work and keep on trolling the trolls.
When you have a tripod shot like that, get your camera in the focus you want, and then switch the lens to "manual focus." The focus will be set, and you won't go in and out of focus like you did there. Awesome video as always! I've already built your first band saw......maybe time for an upgrade?
HEY... I didn't notice it till you pointed it out but your shirt sleeves are entirely your business!!! thanks for your content enjoy your creativity and ingenuity!!
I absolutely love your machine builds. Seeing you tackle yet another bandsaw, i finally gave in and bought all your bandsaw plans. Super excited to start building in a few days!
I have a tip when you thread machine-threads into wood. After the first round with the threading-tap, you soak the threaded hole with extra thin super-glue. After it has set completely, run the tap through the hole once again, allways dry and de-greased. Then you might want to repeat the process one or more times. Make sure the tap is clean before repeating. The glue cuttings tends to stick to the tap grooves and might damage the threads on the next pass if not removed. I use a needle to scrape the grooves clean. It flakes off quite easily. This strenghtens the threads greatly and protects them against wear as well. Do not use "Zap-Kicker" or Acclerator, just take your time and let the glue set as normal. Use parrafin-wax, bees wax, or similair compounds as a lubricant as needed in the final usage. Not oil or grease under any circumstances.
Enrique, Desde Argentina, no entiendo mucho el inglés pero muy contento felicitaciones eres un fenómeno con tus vídeos aprendí mucho. Aunque aquí no hay las herramientas ni materiales que existen allá en fin me arreglo con lo poco. Saludos.
As to balancing the wheels. When building the wheels you could place threaded inserts every 30° (15 works better) and use those to attach you weights. The farther from the center of rotation the better. There are phone apps for checking vibration levels. Before I retired I used to have to balance large centrifuges for waste treatment plants after rebuilding them. Hey, it's a growth industry, every body poops. And every year there's more people. For centering the bearings on the screws. Just use short bushings either out of the hardware store selection or from plastic tubing if it fits.
Hey Matthias, the shaking gets worse, because as you are adding weight you are shifting the natural frequency of the frame clsoer towards the frequency of the oscillation. Balancing the wheels is the way to go, or if you want to be fancy about it, add a tuned absorber.
The wobbling you described makes me think of those Japanese pagodas that have a giant beam and joints made to move and absorb the energy of earthquakes.
Your attention to detail is always awesome. But showing at those gorgeous, brown eyes at the end is genius. Everything goes right out f My head and I have to watch the video a second time. :-) -KJ
I´d like to ask if the downward angle on the bladesupport on the upper guide isn´t counterintuitive. I know a downward angle might look like it guides the blade itself better, but wouldn´t an upward angle deflect stuff like clogged up sawdust way better then this "pit" that might even catch bigger stuff and get the blade stuck? I doubt that funnel shape is necessary since the blade is already "threaded in" if i might say it that way. A funnel helps if stuff is not guided from below right?
That's why the bottom guides aren't downward. But the downward angle also puts the blocks closer to the workpiece, and wood in general wears less if it's rubbing out of the grain than in. Into the grain could lead to jamming if the blocks get loose too.
Being an engineer you should be familiar with how buildings are designed to survive earthquakes. They have liquid plates under the building so that the building can shake with the earth movement and not come apart. That is the same reaction you were describing with the wobbly base on the moving bandsaw. Just thought you would want to know. Love your builds.
A family friend was using my father's engineers lathe, and his loose sleeve was caught by the chuck jaw... result was a shattered wrist in about one millisecond! Thanks for pointing out the lurking danger in your case.
If you can get some elastic strap 50mm wide or so you can make some arm bands you can put over any shirt. Snooker players used to use similar things with their shirts. Cheers
I didn’t notice ether, I had to run the video again to notice so if you had not told me I would be none the wiser. I have already watch most of your videos three or four times, even your oldest videos as I have most of your plans as well
For holding bearings, I like to use countersunk bolts with a head a fraction larger than the inside diameter of the bearing. E.g. M10 for a bearing with an ID of 20mm. It is nearly flush with the bearing and keeps it nice and centered.
I've been watching the progression of this build and the quick an casual sawing, thinking to myself "geez, how often does he get cut?" Then right in the beginning of this video a healthy hand turns into a cut hand in the next scene.
I think there is static balance which you fix but dynamic balance that is probably the cause for your imbalance, that is, your cg is centered in the plane of the wheel, but you have weight differences in the other planes. See what a car tyre balance machine does when it spins the wheel.
I enjoy your videos, and realize your plate is pretty full and you kind of do your own thing, which i respect. But would you consider making a video just about precision and errors. When you may or may not want or need precision, ways errors are introduced, how to avoid them , etc. In your videos you often comment about this but i thought it would be nice to have your take and thought process on it in one video. I was thinking about this when i see you trying to dial things down to a few thou and then wonder if its all for naught, as something like thermal expansion of the table saw or band saw blade or the axles might be double that amount
Maybe foam and paver base to dampen the vibrations. Would have to play with the thickness of the foam a bit to find a good balance between stability and dampening.
Coming along nicely, Matthias. Always enjoy watching you build your machines. Is it possible for a total (estimated?) build time to be mentioned when the saw is completely finished?
Second this! It's a cool project but I can't help thinking I could spend the time working my normal job and buy two bandsaws with what I'd earn in the time it took to make this one. I guess that's probably not the point of it all though. I guess that's kind of like looking at people riding bicycles and thinking 'but I can drive way faster'.
@@stevem815 I think the idea is he gets his own custom design to how he wants the saw to function, which a store-bought saw wouldn't give Matthias. I imagine he gets extreme satisfaction in and at the end of the building process.
Amazing work, Matthias! 😃 I'm almost deciding to build my own as well instead of buying it... But we'll see... 😬 Anyway, stay safe there with your family! 🖖😊
Why is the top bearing not rotated by 90 degrees? My inituiton tells me it would run better that way, but I have i seen it like in the video in a lot of bandsaws so it must have some advantages. Whats the reason to have it like this?
I'm going to build this bandsaw. I want to have 16+ inches of resaw height. Maybe closer to 18. Is it a simple as making the frame taller? Will I sacrifice other features or usability in doing so? I'm sure the blades will cost more but in terms of detail work, stability, etc. Thank you.
I'm thinking the shaking was coming more from the bottom wheel. It got worse when you put the weights on top because you were in essence placing them at the end of a lever the imbalanced bottom wheel was acting on.
Could it be that by adding that weight at the top you were changing the center of gravity of the machine. Because with the blade on the two wheels are now one whole unit of balance. I would imagine by putting same weight In the middle of the machine may make a difference. Maybe?
Matthias, could you at some point explain the best speeds and pulley sizes that would be best used in using a band saw to cut metal? I know that you cut metal at times and it would be nice to have a saw set up to cut metal especially if you have multiple saws.
So for the blade guides would using something like nylon instead of that exotic hardwood work ? As I know it’s used in things like top hats and sleeves for moving joints etc. or would bearings being better instead in this case ? Would appreciate any feed back
3:06 It's happening. Won't be long before Matthias starts taking apart DIY machinery to assess the skookumness of hardwood cogwheels. Keep your stick on the ice.
For using the saw before it is done, you can save yourself some work: next time don't make a temporary setup, just time travel like This Old Tony. Oh wait, you don't have an industrial lathe. Maybe you can make a chronometric attachment for the pantorouter though?

@@daniel_bohrer Nope. I missed it. I still have no clue why He's building yet another bandsaw, unless it's just because he can. No worries. If you know the reason, I'd sure appreciate an answer, however, life goes on. Thanks.

That's so fascinating about the resonance frequency. I'd love to see you crunch some numbers regarding this when you get to the balancing.
Funny how much time I spend watching this man make bandsaws.

Turning bolts (or cammed out philips head screws) into flathead screws is one of my favorite power moves!
