- Опубліковано 12 сер 2024
- In this video I show you our homemade sawmill.
We started with a chainsaw that was attached to a sledge, but one cut took too long and the fuel consumption was also very high.
The electric sawmill is more comfortable and faster.
I hope you enjoy the video!

I was running this saw for about 2 hours at about a 30-50% duty cycle ua-cam.com/users/postUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and it did a great job. I used the lever for the built in sharpener to clear chip buildup out more than to actually sharpen the chain. It managed to cut some hardwood stumps much larger than it's size without bothering the neighbors with hours of 2 stroke noise.
Wow bin begeistert !!!
So ne Anlage kaufen kann jeder, aber Learning by Doing ist ne andere Sache.
Vor allen Dingen, selbst gemacht und funktioniert Tip Top
Vielen Dank!
Found this after having the idea and looking for others who've tried it. Thank you for sharing!!
I am needed to machine for run cutting Timber. Plse provide me contact number as well as earlier.
Nice job! It's different than any other sawmill.
A friend made one very similar to this , but he had to star drives ,right hand star was power for forward cut ,, then the left hand star was power for the return , he could cut going both directions, don't know if made it any faster , but it was neat to watch . Just used v-belts as clutches. Mind you, with the way yours works I don't know if I'd change a single thing
I love it! Pragmatic design. Brilliant!
Beautiful system. Just, Beautiful!
Ben your hand crank set ups to advance the saw and to raise and adjust the log height are "elegant simplicity". Such practical design is appreciated. I have used my Granberg "Alaskan" chainsaw mill to slab up 4 large oaks. Very hard work. I found it sawed somewhat faster by advancing the saw bar at an angle into the cut. Will Malloff in his book "Chainsaw Lumbermaking" suggested this also. It would be easy for you to do a simple test to be able to compute whether it would be worthwhile to change your mill to cut somewhat faster with perhaps less strain on your saw chain and more fully utilize your available horsepower , depending on how much sawing you do. A short piece of cant and a bar or pipe clamp could be set on the mill log support. With the clamp attached to the cant and a couple of C clamps holding the bar or pipe clamp to the mill log support. The short piece of cant could then be sawed parallel to the saw head guide rail or angled to point to the far end of the guide rail to simulate what sawing would be like if the 90 degree bar to guide angle were opened up, (if the angle was opened then the chain would enter the where the log is closest to the saw head). Seems to me the greater, practically, the bar angle could be opened from 90 degrees the better. But who knows?
From your "thinking man" mill design I think you might enjoy such a simple experiment. And if angling the bar is worthwhile many would love to know. Thank you for sharing. James
Hi James, thanks for your feedback! Really an interesting idea. I've also heard of that it should bring benefits. But the cutting width is getting smaller and we need the full width more often. If the sawmill is no longer used that often, we try it out.
To try it out, we could just put the wood at an angle. So we can see directly whether it brings any advantages.
A diagonal length cut is longer than a 90 degree crosscut. I see an angle cut as requiring more power since it's longer. Am I wrong?
@Patrick
Yes I agree with you. The chain has to saw more material.
I could imagine that the angle at which the chain enters the wood requires less force and is gentler on the chain and you can therefore make more feed.
@@Patrick-kc5ur Patrick It is all about the structure of wood. With my chainsaw I cut into a 2 foot piece of log from the end as Ben's sawmill does. It was hard sawing and made fine sawdust. Then I put the log piece on its side and made the cut with the bar parallel with the length of the log. It was easy sawing and produced long "excelsior" strands of wood. What I understand is that the darker part of the growth ring is denser and harder to cut. When you saw directly into the end of the log the saw tooth must repeatedly cut through all the growth rings. When sawing with increasing angles into the wood think if a triangle _____i ( in your mind connect the dot on the top of the i with the start of the line). The base of the triangle is the saw cut advancing straight into the log, the hypotenuse of the triangle is the longer saw cut when sawing at an angle - also the line is soft wood the i is the hard growth ring. When sawing at an angle the tooth spends more time in the softer wood and cuts across the the hard growth ring less often and courser sawdust is produced. Less stress on the chain so the chain can be advances into the log faster. I expect this is all set forth in a very scientific paper at the USDA Forest Service Forest Products Lab in Madison, Wisconsin and elsewhere. For Ben's mill this would only be practical if the saw setup were mounted on a plate that rotated on the carriage so change from straight to angled cuts could me made seamlessly between logs. But who knows if it would be worth while? James
Quite and fairly fast , beautiful logs going in . Prefect for timber frame applications
Wow, never saw a chainsaw mill go electric. Good thinking. Pretty nice lumber coming out of that. You must have some kind of oil tank to feed the chain and bar from burning up.
Thank you!
Yes, we decided on an electric drive because our first attempt with the chainsaw was not ideal. The fuel consumption was very high and a cut took a long time.
I think a chainsaw would not have withstand very long.
The oil for the Chain comes out of the blue tanks mounted on the sledge. An oil pump from a chainsaw delivers the oil to the chain.
If you had a 15+ HP VERTICAL SHAFT 4cycle motor instead.
Electric in North America 3 phase has to be in a mill.
I want to go portable.
That is about as fast as a bandsaw mill.
I was thinking of building one longer bar.
Awesome design, I've been working on getting the parts for a bandsaw mill for a single job, definitely considering doing this instead
Thanks for your feedback.
Maybe the version with the chainsaw would be enough for you if it's just for one job.
Nice build. Basically an early Logosol copy. Electric motor is a good idea. Gas engines do use a lot of gas and can overheat. Only thing I don't like about chainsaw mills is the amount of timber lost due to the wide kerf.
Very innovative.
i'd add a small winch to it just set back and push a button over the crank but other awesome idea and that motor is a beast
Great design. Thanks for sharing. Do you think this would work with a longer bar/chain, say in the 36"/91cm length?
Thank you.
I think a longer sword would work too. But because of the greater cutting forces I would use a thicker chain.
It is also important that the chain is sharpened evenly, otherwise the sword will run up or down.
Great design! I have often thought about using a lawn mower engine about 26hp. They have an electric clutch and a belt turning the chain pulley would double insulate the motor from catastrophic failure. I just don't think 3/8 chain could handle the load.
it's an almost exact copy of my Logosol chainsaw mill
Sehr schönes Video. Da geht ja einiges an Holz drüber.
Vielleicht kannst du noch mehr Details zu deinem Sägeaggregat zeigen?
Like it rely nice 👌
what a neat machine by chance you have blue prints i can get from you
Nice, I have a portamill from Norwood and I am looking to replace the chain saw by an electric motor. I like your, do you have mechanical plan of the fixture on the electric motor? Thank Pierre
Hi, thank you for your feedback. You can write me an Email than I can send you some detailed fotos from the sawmill. You can find my Email in the Video description.
I love your design and the simplicity of the mill itself. I am trying to figure out what brand or company makes those height adjusters that you use to raise and lower the log, or did you build them yourself? Thank you
The frame is similar to that of a Logosol sawmill.
Instead of the ratchet with automatic locking, we simply use a bolt for locking
.
The slide is self-built and the lubrication in particular was not that easy to implement.
go with a bandsaw blade
Hi, very nice and inspiring design. Thanks for sharing. Is the 10hp needed?
Thank you.
We took the 10hp engine because we still had it in stock. I think a 7hp motor would be enough.
At 10hp the chain determines the feed speed because it will eventually break at the power of the motor.
Top job!!

Good job.
Wow
Bravissimo!!
Super robota 👍👍👍 Jak zrobiłeś system poziomowania kłody ??? Posiadasz jakieś rysunki budowy traku?? Planuje sam zbudować cos podobnego a ten twój trak naprawdę robi wrażenie. Brawo👏
I'm just guessing here but are you using the big electric motor to drive a hydraulic pump which in turn drives a hydraulic motor which turns the sprocket? Do you have trouble with the hydraulic oil getting hot? Very nice set up. I really like your track system and height adjustment . Very good!
@John Pullman
Thank you for your Feedback.
The chain is driven directly by the motor via a V-belt. What you see in the video is the oil pump for lubricating the chain.
I also think that you get problems with too hot oil if you make the drive hydraulic.
you are wonderfull
Would have liked to see the actual buid,
I see you need to detach the end to change the chain. Something that might make this quicker is to attach the support arm by bolting through the bar instead of clamping. You lose some capacity of course.
Is the 7.5kw engine necessary ? Chainsaws propelled by fuel never have that kind of power ? Also, i am interested in building one of these but don't have more than 2kw of electric power ... Any thoughts on if that is feasible ? It is to saw Douglas fir in max 40cm diameter as i don't have any machine to lift. Thanks in advance
Hi, in my opinion the 7.5 kw is exactly right. The engine has already stopped on a wide oak trunk. I could imagine that the 2kW motor is not enough for a 40cm wide saw cut. Maybe it's very slow and the engine warms up quickly.
Normal chainsaws are not as powerful because they will never operate at full load for that long. The chainsaw I had on a sled at the beginning of the video has 7.5 HP. It was also very slow.
Of course you can just test it with your engine. You just have to keep in mind that it will take longer and make sure that the engine doesn't get too hot.
Hi Ben
First of all very nice build chainsaw mill i have seen. Cutting is also smooth.
I have also started building one but stuck in making oil pump. Was wondering if you have any blueprint for fitting of oil pump.
Thanks
We also worked on the oil pump for a long time until it was perfect.
However, we also have a CNC milling machine at home. This was very helpful when adapting the oil pump.
I have an exploded view of the sled. Write me an email and I can send you the drawing. You can find my email address in the channel info.

I sent you the email with the drawing.
Are we talking bout an oil drip? I'm curious bc I'm bout to build this myself
Excelente
What size is the electric motor? Seen some people using 5hp 120v motors.
Since you've ran it as electric,how many board feet have you sawn on it?
So cool. I'd love to know if it has enough power to cut through a hard wood like oak. At least to cut through it quickly
Works without problems. A cut oak takes a little longer than spruce.
The speed is limited by the chain and not by the motor.
Because the chain gets very warm with hard wood, I use water cooling.
Is there enough power with that motor? I'd love more info, I want to build one like yours
The power of the engine is more than sufficient. A 5kw motor would also be sufficient.
The chain breaks before the engine reaches its performance limit.
How did you gear it to the chain drive? I have so many questions lol
The engine power is transmitted to a shaft with a belt, which then drives the chain and the oil pump.
Can also be seen in the video.
Very nice, I thought it was a band saw at first. What is the worst thing you ever hit with the saw?
Once sawed into a nail. After that the chain was blunt.
I often remove the bark before the cut when there are many stones in the bark.
@@bensch7530 A guy I know hit a horseshoe once.....Lots of sparks
Ohh wow. I think the chain was broken after that, right?
How does a horseshoe get into a tree 🙈
@@bensch7530 It was a giant buzz saw and they figured someone had put a horseshoe on a branch when it was young and the tree grew around it. Ruined a very expensive saw blade
Sehr gute Konstruktion, mich würden auch mehr Details zu dem Sägeaggregat interessieren. (die Riemenübersetzung/Riemenspannung, Sägekettenspannung etc.)
Whats the diameter Of the pulleys? Wery great saw :)
Thank you!
The pulley on the motor has a diameter of 110mm and 30mm on the sprocket.
Hi Ben i dont find a email to you can i get that i need info to build electric chainsaw mill
Hi,
I did not expect that there would be so much interest in my sawmill. Since the email address is not easy to find on my channel, I wrote it in the video description of this video.
awesome job on the mill. Any chance would you know the speed of the chain in rpm?
Thank you.
Speed of the chain is 10500rpm. That's the RPM of the sprocket.
Hey buddy I know this is about 4 years ago but I got a question for you you think you could still help me with the making of sawmill
Hi, how can i help?
@@bensch7530 i need help to make a eletric saw mill
im 60 years old and on ssi
This is the best of the best...how do I get one of those?
Logosol make the mill's frame, and they sell a saw very similar to this saw (Logosol ES8)

Awesome Ben. Would you able to share the details of accessories please? I have a chainsaw mill and would like to do the same. Thanks
@Sapphire Wood Crafts
Thank you!
I watched your video. Definitely runs better than we used the chainsaw.
We only have a sharpener for the saw chains. It is important that all teeth are the same length and have the same angle, otherwise the saw blade runs and then jams. With the file you can not do that exactly.
I would not buy the cheapest device.
Otherwise we have no extra accessories.
@@bensch7530 Hi Ben, how did you connect the chainbar/chain to the motor please? are you able to share list of parts please? I ordered a chainsaw sprocket and clutch drum to start with but any help with this I really appreciate it.
@@sbantu
The chain is driven directly via the V-belt. There is no clutch installed.
For more details please use the email in the channel info.
Great saw. Can not see an email in the channel info. Did I miss it?
Pretty neat, how often do you find yourself sharpening the teeth on this?
On average I would say after 15 cuts.
It is sharpened with an extra sharpening device and not by hand.
@@bensch7530 how long does it take to sharpen that way
@Aaron Mcfee
Sharpening once takes about 10 minutes
Where did you get the motor?
Do you have the hole patterns for the cut adjustments for lifting the logs? Where you raised the log and put the pin in the bar?
@Yoshi Ben
Exactly, all the holes allow me to adjust the trunk in 5mm steps.
From 1:24 you can see how I adjust the height.
Motor speed 2910 rpm but sprocket speed 10500 rpm. Is there a gear system?
Yes there is a gear system. Large pulley on the motor an a small pulley on the chain side.
Would a 7HP air compressor motor work for this build
Yes, a 5.5 hp motor is also sufficient. But of course it depends on which bar and chain you use
How often do u sharp your chain?
It is always different. On average i would say after 15 cuts.
It is sharpened with an extra sharpening device and not by hand.
i have very hard time finding a long chainsaw bar supplier .... someone has an usefull link?

What type of chain are you using?

We use a special chain for longitudinal cutting.
The exact model is called:

That is fast. Its also is pine. What would it be like in hardwood.
The guy that said about a 4 cycle motor
Has to have gear increasing.
Also one with hydraulic. Hydraulic is slow. But torque. Change ratios.
I would like to install a 72" bar. Investigating carbide teeth. For hardwood crotch.
We live in British Columbia Canada. There are mills everywhere. Guys with headsaw mill cut beams and posts. Or portable bandsaw mills.
For $10,000 I could get a production mill.
Has to be portable. Electric isn't an option.
Any segregation. In the planning stages.
@@davewelch1932
Hardwood, for example, oak, we have also often sawed. But it should not be too dry.
Speed when sawing oak is not much slower than with spruce.
Carbide teeth we have not yet tried because we have no sharpening device. But would still know how it works.
Hii
Thats a bad dude
