I believe the runout/ balance on a saw blade like this is measured while the blade is spun up to speed. They often wobble a bit when static. Might be because it will deform due to centrifugal forces when going at nominal speed.
Glued to the screen from start to finish, what else can we expect from a “Donn” video. Totally loved your home made adaptor for the lathe, pure genius.
The blade of death 👹 Everything needs to be 100% correct when building something like that - I have every confidence in you. It will be very interesting to see this take shape.
The design I went wtih was a 1:1 T gear box which would drive the blade via a pulley and belt or chain. This would also allow for a cull 180 swing and angle cutting which means that I could cut siding and hex, oct or what ever sided beams. I helped my neighbor make a few 8 sided posts for a porch. We used a band saw and once we cant the log we then made some logs braces that held the log in place to cut the edges off. While what I was doing was only messing around and doing it with no money invested and things I got for free or a few dollars. It was a fun build and learned a lot of things. If I was to do it all over again. I would opt for a dual blade sawmill much like Marty Ts sawmill that he found a number of years ago. It is very possible to build something much like this with a really nice diesel engine and good hydraulics.

Greetings from Turkey. Congratulations . I am also looking forward to this project. God bless your hands . I wish we could get to know you better. :) :) :)
I think you were very lucky that the motor pulley turned true to the centre & was balanced. Holding it peripherally & turning it, normally you should then bore out the shaft hole, so it's true to the irvumgerence. If the hole is already bored. the pulley should be mounted on a shaft & turned on that, so the circumference is turned true to the centre. Glad that you were in luck this time!
Salut à toi Donn. Toujours un plaisir de te retrouver. Encore un super projet, que je vais suivre. Avec toujours un peut d'impatience, j'attend la suite. Bonne continuation.
No kidding, this is something I've been imagining for a while. Lucas mills are hard to come by and expensive, this will be a very interesting series! I'm excited to see how it goes!
You are quite the craftsman my dude. Some people might not understand the difference between a circular cut vs. a band saw. You don't have to make a through cut which increases the quality of wood stabilization. Also less waste.
Yep, those Lucas Mills are pricey, even used. So, I can see where you might want to just build one of these nice set-ups for your own custom and quarter sawn lumber production. Also, the options for planning and sanding wide widths make the labor savings in these platforms very attractive. Plus, it's going to create some very good content for TH-cam. 👍👍
I messed about making something like this with no real money for the project and with mostly free stuff and a few bought things. Though this was about 10 years ago and at that time if I would have had the funds to buy one of the Lucas mills I would have gone with the 4/10 model. This was their 4 inch model. At the time this was the only thing I wanted to do. 1x 2x material as the lumber I could get was cotton wood and I have helped my neighbor cut a bunch with his bandsaw mill. I just did not like bandsaws because they could have compounding problems. Swing blades were ideal and after I showed my neighbor the lucas mill he was kinda sad cause he would have bought that instead. If I was going to do this all over again I would build a dual blade mill. This is where the vertical and the horizontal blades are fixed and you get a single board from one direction of movement. I would also build a bed that can clamp and alinge the log with a push of the button. You might lose the last 6 inches of the log yet in the end its worth to improve cutting times.
Donn, Why are you making a swing blade when you built a bandsaw mill? I would love to hear you give a comparison between the ease of build between the two and possibly hear your views on the pro's and con's. Your videos and builds are great. Thanks for sharing!
I sold my bandsaw mill. I can tell you the pros and cons right now (in my opinion): swingblade (compared to bandsaw) PROs: more simple, less parts to maintain, cheaper, more reliable, faster cutting, no need to load a log on a frame. CONs: limited cut width with circular blade. And that's about it. It's just my personal preference. I'll tell you once I've finished the swingblade and used it a bit to get an actual experience. I might be wrong.😀
Thanks. Im about to start a build and am still weighting my options. Swing blade def is appealing. Where did you get your blade and what size motor do you plan to run?@@DonnDIY
16:55 instresting fact about blade runout as you breing the saw up to speed assuming its 10k rpm the run out will go away. If you look at old eairly 1900s blade style saw mills the blades were not flat they were cuped as the blade spun fast centrifugal forces flated them out, the only way a blade with run out might be a broblem is if the sawmill was underpowered and the blade stalled out. With this theory in mind you wont notice any blade runout and because its so small it wont take much force to right it to true. I think it work just fine with more run out, that said it probably a bur on one or the mounting holes or the saw blades holes. A hair could send it that far out.
Oh Boy !! Going to be another great ride along with you Donn. Another great fabrication adventure for sure. Looking forward to every video. Stay safe and have fun. Fred.
First time I saw a swing blade saw was the Lucas Mill that Wankerstar got just before I stopped watching his channel. They’re quite the saw and can do amazing work.
Gday I sell these for a living and I think you’re going to need to strengthen the pivot points as there’s a lot of force on them. Best of luck with the build cheers from australia
Before I read your description, I thought you were about to make a "Amusement Ride of Death" or something with this xD Will be interresting to see the final result :)
Nice work! I'm sure you have already researched this Donn but the blade bolts usually 12.9 grade with nyloc nut on the back. From memory the blade speed is around 2000rpm. Looking forward to the rest of the build 👍
Hey man! Thanks for the heads up. I looked around locally and found these 10.9 grade bolts and planned on locking them with nyloc nuts. In the light of the information you provided I just ordered a set of 12.9 grade saw blade bolts (with nyloc nuts). So that issue should be in check now. The manufacturer of the blade gives optimal blade speed around 2400 rpm, max 3500 rpm. According to my calculations with current pulleys my setup will have 2900 rpm which I definitely want to bring down to optimal.
don't know if your use will be harsh enough to cause issues but i wouldn't personally use countersunk bolts to hold the saw on. it will create high stress areas that could lead to cracking or bending in the saw. i would machine matching colliers with the inner surface 0.002 to 0.004 thousands of an inch lower than the outer clamping surface. this spreads the stress more evenly and allows a little natural flex that will prevent bending if you hit a knot or timber bound sections in a log. it is very important that the collars match or it will flex the saw one way and cut out of square. a perfectly flat collar is acceptable. a cone shape collar with the inside being higher than the outside will cause issues. I've worked in an industrial sawmill for 5 years and as a saw filer for 3. and that is the standard way to mount a circular saw.
Hello: I have seen most of your videos and I have been your channel for a long time, I think it is the best channel of the subject you work for. In this video of the sawmill I have seen a weakness, and I tell you from experience, the support where the cutting disc is held would be good that you did an outer flange so that the album did not crack, and so it would be safer. In some cases similar machines come with the flange in very poor condition for not having an external flange that is sandwich and thus reinforce the union. Regards.
Proper saw collars should be used to mount a blade being used as you are. The next blade you purchase will be easier to maintain with inserted teeth rather than the carbide tips you went with.
Donn, I have a 558 mm (22") forestry blade with carbide teeth, and I took it off the machine it was on at a local scrap yard. I'm hopeful it will work for my intended use.
the pulley should be machined coaxially, holding a round blank in the machine chuck and already fixing the pulley on it, then you will get full alignment with the motor. it is worth making a washer for fastening the saw blade, with the washer the load will be distributed more evenly, the torque from tightening the bolts will also be evenly distributed over the surface of the disc.
سلام و خسته نباشید استاد- من بیشتر کارهای شما را دنبال میکنم واقعا عالی و کم نظیر هستند شما یک صنعتگر بی رقیب هستید و واقعا همه فن حریفید اگر میشه طراحی و ساخت یک دستگاه پنج کاره نجاری (رنده-گندگی-فرز-کم کن-اره گرد) را هم در برنامه کاریتان بگذارید چون دستگاه 5کاره گران هست و هر کسی نمیتونه بخره خیلی ها با آموزش های خوب شما ،دستگاه مورد نیاز خودشان را خودشان میسازندو ازش استفاده میکنند متشکرم
It would have been more expensive to get a blade with the inserts, but I recommend it. If you hit something solid you will lose teeth. With the inserts it is a simple matter to replace the teeth and with your current blade you have to stop and take your blade to a specialist.
Thinking of a weak spot at the connection point of the shaft you need to use an axle of a car or truck, or mount the blade in the middle of the shaft✌🏻👌🏻♻️
Interesting new projeckt Don ❤ many off the swing blade sawmill’s i have seen had hardly no clamping system off the log, but gravitation and therefore have been pretty underpowered, to have a feeding force a 20-24” saw blade requires especially cutting 10 to 12 “ backwards, it shall be interesting to follow the further progress off your Swing blade project 👍
I have planned no clamping for the log either. Just setting the log on log stands one time and then cutting all the boards from that one log position till the very bottom scrap slab. I really disliked the continuous log setting on my prior sawmills. Let's hope this sawmill is exactly what I want. Have to try different things here in life I guess.😀
@@DonnDIY With the blade this size and a 3KW electric motor the Saw speed will be rather slow and the feeding speed rather low so the log will surely lay still but from my experience with hundred kg. feeding power from circular sawmills on a static log with a moving saw blade, the log must be clamped one way or another so that the log docent fly to the moon 🥴
When can we expect to see episode 2? Sure would be interested in seeing the project through to completion. Also I am very interested to see it in action to see the advantage of those non through cuts over the bandsaw cuts.

The cad drawing at the end enlightened me as to what this will be for! I also can't not think of Sling Blade the movie when reading swingblade!
I would never in a million years have thought about using the lathe to drill holes like that. AMAZING idea.
Always make holes using lathe the same.
Fun to see such precision engineering applied to a medieval looking contraption 😊
Lacking in the looks department and overcompensating in other areas. 🤣
The old sawmills, i.e. the spinning blade of death. Can't wait to watch the build.
I cant belive my 2 favourite channels are now both building a sawmill. You and j.mantzel
Cómo siempre excelentes proyectos! Felicitaciones. Saludos desde Mendoza Argentina 🇦🇷
Now that is a proper lathe! Slight lathe envy
Darn you Donn. Yet another video I'll be addicted to watching.
I believe the runout/ balance on a saw blade like this is measured while the blade is spun up to speed. They often wobble a bit when static. Might be because it will deform due to centrifugal forces when going at nominal speed.
Por isto estas laminas sao para corte com baixa rotacao
No way man, the wobbles while getting up to speed are resonances. Runout should be measured at low speed and not run up to speed if it’s too high.
Well done fella you solved that problem real fine I would like to see your saw when it is done...
Buen trabajo amigó gracias por compartir tus conocimientos, resive un cordial saludo desde Puebla México 🇲🇽
Hi Donn nice to see a new project im happy now allways a good video thks from Sid.
what a wonderful display of skill and craftsmanship .. :)
i hope you dont mind me saying this , that is a dam good job . thank for leting me watch you do all your work .
Looking forward to this build project. I don't think a swingblade style sawmill can be beat for milling dimensional lumber from logs.
I agree 👍
Excellent workmanship, and great homemade device for clamping the shaft for the lathe operations. I have a bandsaw mill, and it is all I need.

Can't use two collars, the blade has to be completely flat on one side to make the cutting possible through swinging motion.
hadn't thought about that you're using the saw in a cpmpletly different kind of situtation.
Hello: I have seen most of your videos and I have been your channel for a long time, I think it is the best channel of the subject you work for.

Can't use a second flange - the bolt heads have to be flush with the blade body. Using second flange would render this swingblade sawmill useless.
@@DonnDIY OK
Proper saw collars should be used to mount a blade being used as you are. The next blade you purchase will be easier to maintain with inserted teeth rather than the carbide tips you went with.
The blade is designed to run flush with log, can't have a collar that extended past the curf of the blade

Donn, I have a 558 mm (22") forestry blade with carbide teeth, and I took it off the machine it was on at a local scrap yard. I'm hopeful it will work for my intended use.
24:46 raises the question; How much wood can a wood woodmill mill?
the pulley should be machined coaxially, holding a round blank in the machine chuck and already fixing the pulley on it, then you will get full alignment with the motor.
it is worth making a washer for fastening the saw blade, with the washer the load will be distributed more evenly, the torque from tightening the bolts will also be evenly distributed over the surface of the disc.
