We all know that that band saw blades that are designed for resawing have fewer teeth. I've always wondered why, but now I understand the physics behind it, and it makes perfect sense. You have a great way of explaining highly technical concepts in a way that laymen like me can easily grasp them. You're a true asset to the woodworking community.
On a RUclips quality scale of 1-10, this video is an 11! The only issue I have with this channel is I just can't stop watching the entertaining and informative content.
I don’t think there is anyone else who has the genius mind, but also the ability to teach and explain things in a light and fun way. Matthias you are a wonderful man with a fantastic way of helping people learn. Thank you for all the hours you have put in just to share your love of woodworking and engineering with people all over the world. You have been such an inspiration to me and I wish you the very best with everything life has to offer
I spent years working at an informal science museum. I just want to say your work is really really good. It does a wonderful job explaining difficult engineering problem. Beautiful. Thanks so much.
This is great teaching. The best explanation I have heard of the problems of resawing and what to do to correct them. Thank you. You are a very good teacher.
I've been working with wood since at least 30 years and of course I know about using the right blade for the special purpose, but it's the first time that I know the exact reason - a simple but most effective way to explain that matter. Thanks a lot and best wishes out from the Oberpfalz, Bavaria.
Matthias, thanks for another great video. Your explanations are complete without being complicated and your illustrations take all the mystery out of the analysis.
I've watched a couple of videos you've done where you explain some particular subject and each time I've been very impressed. I am amazed by the thought you put into them, as well as the props you create to illustrate the ideas.
When I "came here" I recognised that I had seen this video before, but I couldn't help myself and viewed it again. Your explanation of the "sawblade physics" is simply magnificently elegant, "simple" but fantastically comprehensible. Kudos.
Matthew, I believe this is probably the most informative reason why so many people have trouble using bandsaws. You've just explained very effectively how they can go wrong, due to forces which we fail to think about but which you have clearly thought about and worked with to get a solution. You have probably changed the future of bandsaw design, it's just a matter of time before manufacturers begin improving them. Well, we can hope, lol. Best regards, Steve
This sawdust demonstration idea is a very elegant educational tool. Your channel continues to surprise and impress me. Fantastic stuff Matthias, please keep it up.
What a great way to explain things. Use wood to explain woodworking. Matthias, you have a knack for explaining things in a way that communicates sometimes complex, detailed scenarios that most anyone could understand. It's a pleasure watching you.
learned a lot about setting up for resawing. thank-you for this most informative post. sawdust modelling a genius and simple way of explaining bandsaw physics.
This was a great demonstration and narrative. I have not used my 1st bandsaw yet, a new 9" Wen, but now that I see the concept of the dust collecting in the teeth, it allows me to better know what is going on in the kerf allowing me to work the stock more effectively. Thank you!
I have a small hobby band saw with a blade drift problem. This video taught me exactly why the problem exists and how to fix it. Thanks for taking the time to explain it.
brilliant! you are a natural teacher. from another teacher, thank you for not selfishly hoarding your knowledge. i was lucky to stumble upon your milk crate video and plan on spending several more hours learning how to better communicate with my music students with your inspiration to use for visual aids more. this bandsaw video explains what i put into practice in my wood and metal studio, from experience, so clearly, i am still grinning! thank you.
Hey Matthias, I was going to message you to ask your advice on bandsaw blades as I'm currently looking at purchasing a bandsaw with different tpi blades and I decided to look through your videos first to see if you had already discussed the difference in blades, it's great that you take the time to make these informative videos and the way you set them out makes it so easy to understand the differences and get the best out of tools and projects, thank you very much for all your effort.
Watched a couple of your videos, and after this one you have a new subscriber. All of your videos have helped me understand my bandsaw better, which in turn has made the quality of my cuts a lot higher. Thanks for help and keep up the good work.
Matthias, I hope you are in the teaching profession beacuse I'm always impressed by your simplified analysis of mechanical issues. You never fail to impress be with your ingenuity. Thanks
I have watched many of your videos and enjoyed each one..i enjoy your explanations and find the videos inspiring and educational .The video quality and camera angles are great ,this with the saw dust model is one of my favorites ,so thankyou matthias..thankyou.:)
That visual is amazing man I've run into that same problem many times before and thought that might be the issue but seeing it your way just slammed the nail on the head. Thx for the upload.
Great video and timely for me as I just purchased a MM16 bandsaw which I will use for resawing and many tablesaw duties. Now I'm more educated in what to look for in bandsaw blades. Thank you!
+Amir S Wow I had no idea, believe it or not, I also did work at RIM for a couple years, it doesn't surprise me he's probably was one of the few people that made it great once upon a time. But now that they've gotten rid of a lot of the people that were innovative, they're know in the hole they're in...
Indeed, if you have to adjust for drift, there's probably something wrong with the setup. Once everything is set up, the optimal setting always ends up with the fence square.
Really helpful - thanks. What you covered is probably what most people have been told but you explained it in a way they can understand - and you added in extra advice like the metal fatigue encountered when using smaller wheels. Should make purchasing decisions easier to justify when looking at the the bigger capacity bandsaws - it did for me anyway. Cheers.
NICELY demonstrated sir! Thanks for taking the time to put this together for us. I love that you built clever little models and everything... but I suppose I'd expect nothing less!
Very impressive matthias! No dislikes! You my friend are a master at this you may not have your own show on tv but your doing just as well on RUclips! I respect you for what you do and love your videos. Wow that sawdust example was creative. Thanks you for being an inspiration to me in woodworking I appreciate that
Thank lots. I am a new subscriber to your tips and have learned more in afew days from you than from most of my previous wood working efforts. Thanks again.
Anyone else who came here because Matthias recommended to enjoy articles from 2012 instead of a new article yesterday? I really liked this explanation here, so I rewatched the video with pleasure.
Wow you should right a book. I've got books that are all about bandsaws and they don't explain it as well as you have. Very, Very, well explained and great demos.
Ah, very informative as always! I had some general thoughts on this subject, and some theory on why problems occur and how to fix it. However, my theories on why the problems actually occur was not good enough and basically based on "gut feeling". This video explained a lot! Thank you : )
thank you for sharing your knowledge. You are the first to really explain in detail the dynamics of what the blade is doing to the wood. The wood demo is great. I would like to use this video in teaching some kids about ban saws. let me know if that is ok. Have a great new year and we have subscribe to your site. The Rivera Family and friends. God bless our troops.
I am thinking of building a belt sander, but it would be more a 6x48. I bought a 2x30 for $50. That is so cheap, it's tempting to buy another one just for the motor! Really can't build one for that price.
very good video Matt. something we all can use and learn from we're not all into wooden gears and complex jigs. But this is very useful information to all of us woodworkers. THANKS.
Mathias, you are too hard on yourself! Your responses are great, and I enjoy reading them! Again, I find myself wishing I was just half as smart as you. Thanks for this vid my friend!
This is still the best video on the physics of resawing. I have found that you can reduce the downsides of "excessive" resaw height with suboptimal power and/or tension by reducing the number of teeth in the blade. There's no reason you can't make a half inch blade with TPI lower than 4. Let's say 2 TPI, since you installed the riser and doubled your maximum resaw height. You could have the same number of teeth as with any larger blade. The longer, skinny gullets wouldn't necessarily help, much. But this would reduce the feed pressure:sharpness ratio you need to still get a minimum bite that's good. So your saw's lower maximum blade tensioning ability is no longer causing significant blade drift. This would also halve the amount of horsepower you need, compared to the 4 TPI blade. The only downside of this is that you cut at half the rate and you still need somewhat sharper blades (but not nearly as sharp). If you couldn't sustain that rate at all, before this change, you're at least expanding your capabilities. You can make that thick resaw; it will be a straighter cut; you won't bog down the motor. It'll just be slower.
very nice video... i've seen lots of your videos and this is a great video that explains very clearly... should be introduced to any student learning shop.
Excellent explanation and helpful. I make band saw boxes though and many times I have cut through 5.5" of figured maple to make a hidden hinge with 3/8"D and I've used a 1/8" wide blade with 14TPI on my 12", 37 year old, Craftsman band saw. Theoretically this should not work, and if the blade is not very sharp and tensioned high (as you said) here will be bowing and not a straight cut. For resawing I use the Wood Slicer blade on my 14" Jet band saw and it works like a champ. woodworks-by-donna
Great video on the basics, what is the realistic maximum thickness can you resaw on 14" wheel, for most domestic species, and then for the denser tropicals? How much drag does an improperly set tooth create? How much blade wandering is caused by from miss-set teeth? Is there a rule of thumb for feed speed versus thickness versus species? Have you seen the carbide tipped blades that produce a nearly planed finish?
really cool video! one time i broke a band by cutting a thick piece of wood. think it was birch. pretty hard wood, lol, kinda like the way you present things in your videos! keep up the good work. greetings from germany
Great Job! In Metal cutting generally there is some formula for a minimum and Maximum number of teeth when compared the the thickness of the material being cut. I am assuming based on 40 years of woodworking in my shop... the same is true. For a faster cut, less teeth, but... if the wood is thin, you must have at least 2-3 teeth in the wood. I like your comment about "You just need a bigger saw".
Thanks very much! Very well explained and very helpful in understanding what goes on during resawing! Taking all this in consideration will ensure much better results. Again, Thanks!
The demonstration with the mock bandsaw blade and sawdust was excellent. It does not get any clearer than that!

One of the best vid's I have seen on explaining resawing and how it all works
Matthias, your explanation is just great, thank you. The illustration with the saw dust and the wooden blade, man, it's good!

This video covers precisely the type of cutting I'd like to do. Thank you, Matthias, for sharing your knowledge.
This is a very creative illustration, made me appreciate the significance of the gullet - that underrated part of any saw blade.

I thought it might, but experimenting around with it, I can't say that it helps. The way the blade guides push the blades also has a huge effect.
Great video and timely for me as I just purchased a MM16 bandsaw which I will use for resawing and many tablesaw duties. Now I'm more educated in what to look for in bandsaw blades.
Thank you!

very well done. Just what I needed to know in the shortest form. I look to your channel first every time. Thank you.
Your illustration of the band saw action is very inventive. Thank you for the tip.
Excellent demo. Your explanations agree with my own understanding of what is involved. Particularly liked the sawdust-as-board model.
Thanks for taking the time to make this demo! It was quite informative and I really appreciate the blades through the saw dust.
NICELY demonstrated sir! Thanks for taking the time to put this together for us. I love that you built clever little models and everything... but I suppose I'd expect nothing less!
Extremely thorough explanation! Awesome, thanks for sharing.
Well done!! Your explanation with the sawdust was very easy to understand. You are obviously a smart guy. Thanks for the video.

Finally, credible information on the internet! I needed this info at just this time. Excellent, thank you.
man, this is such a usefull video, all these years later even. Thank you very much
That's a superb way to explain how a blade is affected, good work.
I love Wooden model Explanations!! Best way to get the whole picture Thanks!!
Excellent explanation, and the wooden blade with sawdust “board” was brilliant!
As always, very informative in a easy to understand and clever way of presenting the information.
the more I watch him, the more I like youtube... thanks a lot dear mattias..
Fantastic and very instructional way of the basic process of sawing with a bandsaw. Excellent!
Thank you! Im new to band saws and this has been invaluable.
wow, loved this. I knew about the TPI, but I did not know why.... That visual was an amazing learning tool. Thank you.
Wow you should right a book. I've got books that are all about bandsaws and they don't explain it as well as you have. Very, Very, well explained and great demos.
You did a really great job with this. Looks like you put some time into helping people understand. Great job!
What a brilliant way to explain! And I found this video today, October 5th - World Teacher's day! Providential! Thanks a lot for sharing!
Man, I wish Matthias had been my shop teacher in school. I would have learned a lot.
+CategorySchematic I wish I even HAD shop in high school.
+CategorySchematic i think he would be a good teacher in every subject. his explanations on difficult subjecs are always simple and easy to follow
+CategorySchematic Me too, if he'd been my teacher I'd still be there 30 years later because I wouldn't want to leave!
So glad I watched this before buying a bandsaw. Thank you Matthias!! I'm an educated consumer now! ;-)
Still providing the best info on the web. Thanks.
Ah, very informative as always! I had some general thoughts on this subject, and some theory on why problems occur and how to fix it. However, my theories on why the problems actually occur was not good enough and basically based on "gut feeling". This video explained a lot! Thank you : )
i wish i had these vids years ago. would have saved a few head aches. brilliantly explaind as always.
Great video, I have had problems with my saw drifting when I resaw. This video does a lot to explain those problems.
Hi mate. That was an excellent presentation . I loved the prepared saw-blades you made. Even I understood it. Well done mate.

excellent. Thanks for the advice. I just tried my first resaw this past weekend and now know why all these things happened!

Brilliant. Both informative and precise.
Many thanks for sharing your time
thank you for mentioning metric numbers as well ! love your video!
Love the sand visual of how wood is removed. Ingenious!
Thanks, that explains why my first attempt at resawing ended up dished on one side bowed on the other, if you get my drift, no pun intended.
Update, new blade and setup like the video and success ! cheers.
Thank you. I just got a bandsaw, was not too sure on what blades for what job. Now I know for sure. Thanks again.
Excellent explanation! I'm about to receive my ordered band saw one of these days so this will for sure come in very handy.
really cool video! one time i broke a band by cutting a thick piece of wood. think it was birch. pretty hard wood, lol,
