Thank you for posting this video. I like the creative way you use a chainsaw blade and bar with a powerful motor. Excellent!
Thanks! The idea to use the bar and chain does not come from me, I just copied something that was already made, but with some tweaks here and there.
Now that is clever. And the log 'trolley' is inspired. Thanks a lot!
+Ian Simpson That log trolley is a necessity for the saw mill if You don't have a loader.
Thanks to your video, I now realise that......
Got to be the best rig yet. Good work.
Cheers!
Great design and idea. Never seen one with a chainsaw bar built. Kind of like a Log slasher for logging. Makes perfect sense. Thanks for sharing. Wish I had the knowledge to build just for myself.
Reid Johnson Nothing complex about it. You should build it! ;)
very cool man, inspiring !
***** Thanks! ;) Good to hear that!
Dont normally like tunes but that was perfect. Nice saw too!
Patrick Wolbert Thanks, man!
That log mover is ingenious
Awesome just bought some plans thanks
Dope love it
Nice job bub!!!! Makes me want to save my portables for large fallen trees, and build one of these for my smaller more managable trees. COOL DUDE!
Yes, I agree. For smaller trees it works just perfect (up to a half meter in diameter and four meters in length), but when I have to cut a 11 meter log it is a pain in the rear to adjust the cone shape because the log will bend when not supported correctly.
nice setup
Thanks! The sawmill has gone through some changes. Soon there will be a video of all the changes I made.
bloody awesome.Thanx for sharing.Love your "woody trailer" with the alloy wheels ;-)

solkim133 Thanks! It's my little worker bee - the size is small but carries a lot. ;)
lookin good
Dude that's a cool sawmill and your music is enough for me to join your channel
Brilliant work man.
+JustinTrojan Cheers!
Neat logging arch for carrying the timber.
Thanks! It was inspired by "LogRite ATV logging arch". Brilliant tool I might add.
Ingenious! Great video thanks for sharing
+Doubleheader2 Thanks for watching! ;)

good job! I made one too..and I am developing still this..
It looks very smooth in operation. This is the first chainsaw mill with a pulley to drive the chain. And it makes perfectly sense because chainsaws run much faster than a 2700 rpm motor (i live in Europe so i have 50Hz). That looks about a 1 to 2.5 ratio. How many Kw does the motor have, it looks 2.5/3 or something around that. I'm thinking about making something similar and I want to look around to see what others have done in order to have an idea.
Nice build. You do great work.
dadgad68 Thanks, man!
this is best vid on Diy chainsaw mills ive Ever seen . ive been surfing for months now. Perfect .wow love it wish i had it in my woods. at the end of my road to nowhere. sank
Thanks. Thanks for watching.
Thats awsome , Well dune aye !
Thanks, man!
Excellent!!!!
This is amazing.
+BaconNorris And handy also! :D
Awesome work!
That's some great thinking right there!
+Frank Hammer Cheers! The best thing about the chain saw mill is you don't need a specialized sharpener, you can use a regular file and sharpen the chain like on a regular chainsaw. The sharpening angle is different though. Really great in my opinion.
Do you sharpen the chain at 10 degrees for ripping?
I saw some videos on guys sharpening band saw blades easily with an angle grinder.
I use ripping chain and try to copy the angle what's already there by hand. Haven't really measured the angle but it's definitely different compared to a cross cut chain.
nice!
wow this thing is pretty sick
Andy Sherwood And practical as hell! All of the lumber I need I mill myself with no problems. :D
Outstanding work. I'm impressed.
poeplay2008 Thank you!
That is one sweet rig. I was thinking of build something similiar but with hydraulic motor instead. But now when i see how
nice your mill works with just an electric motor im not so sure anymore.
J1I9M7M4Y It works good. If You use hydraulic You still need to have some sort of power source and when transmitting power there's some of it lost. Allthough hydraulic system requires less maintenance than mechanical one but then again costs several times more.
awesome work.
Thanks man!
good job. I made one also it's nice to see different way of doing things.
+charles richard Cheers! Yup, there's a variety of chain saw mills out there.
I'd take the hand crank off and replace it with a window motor off a car and a speed adjuster. A cutoff switch at the end would be a good idea also.
Good job on your build.
I actually like the fact that I'm hands on while milling, otherwise I could get bored and wreck something while not paying attention to the mill. But Your idea is very good. It just takes time for me to get there eventually. Thanks!
Really nice.
+Thomas Harrell I appreciate it!
great saw...i am in the middle of building a chainsaw mill and just might switch to one using an electric motor.
+mistertom718 Electric motor is good due to the lack of exhaust fumes but restricts the mobility though.
Sweet.
komer west Bitter when in need of chain sharpening or other maintenance. :D But I agree on the sweet part too!
Love it. I like simple and like home made even more. Just started build on a band style mill using go-cart parts. Only videos I have posted are on concept but I have started welding and will be posting more soon. I hope people will tell me if they see any problems with my design before I get to far into it. Being a band mill makes it a little more difficult to build but I have a lot of hardwood that eats chain almost as fast as chain eats it. Thanks for posting yours.
onewyatt1 I'm also thinking of converting to bandsaw mill, or just making another one entirely. The chainsaw mill makes a nice cut up until the bar gets worn (even if the chain is sharp). But I've almost completed a sauna with the material cut on that homemade chainsaw mill so I have nothing to complain about. So you have cut your hardwood with a chainsaw up until now? I think you have a great thing going and bandsaw mill is the best choice you can make!
***** Back in my younger years, I cut a lot of trees for a living. Never cut with the grain like for lumber but if cutting hardwood that way is like cross grain, I would think chain and bars would have to be replaced often. Primary reason I want to build a mill is to build me a cabin, can't afford to other wise. Health had me laid up for last 3 years but getting better now. Hope to resume construction on the mill shortly.
onewyatt1 Glad to hear you're doing better health-wise. I can honestly say I couldn't afford the sauna either if I wasn't cutting all of the material myself. I wish you a great build!
***** Yep, me too and I hope you do one also. Have a good one.
Sehr gut ✌😃👍
Way too cool. You may want to buy a 100$ winch to pull the larger logs up onto the mill. None the less..very clever!
jccoolwood Already did it. Check it out: ruclips.net/video/Hs6WiUoIoP8/видео.html
Simple straight fwd. the kerf is maybe no big deal- vibration and lubrication a real necessity in a build like this your torsion box above blade could be stiffer- otherwise corner gussets on those thread joints. Beats hell out of $3000-10000
Any advantage as compared to a bandsaw style? Looking to build a mill here soon
Hi Donn,I just got to see this video.When did You build this one?What's the title of the video? GRATE JOB as always.
Brilliant. A band saw is another option, thinner blade.
+aguilayserpiente The next sawmill I'm planning to build will actually be a band saw mill.
Cool, Donn D. I like that better than the spinning blade like on the Wild Alaska show.
Nice
Cheers.
I like your mill if it was my mill i would install a couple of brushes on each leg in front of the casters/wheels to push/sweep the sawdust of the rails as the casters ride the rails
+Roc Lo Usually that type of mill has brushes on top of the casters. I was lazy and didn't install'em.
Boy that is a dandy!
EarlRausch ;)
Love the mill. How did you figure chain speed or rpm, for pulley size ? Thanks
Tiffany Davidson :)
Great looking mill Don.
Are you using a ripping chain on it?
Yup, I did. Also the bar. It makes a 7-8 mm wide cut instead of 10 mm cross cut chain.
really nice...been pondering 'bout a similar setup...or a circular swing blade, which would eliminate the chain oil and pretty muc sharpening too and has a narrower kerf. still...very nice in deed...
Thanks! It does the job for me right now. I've been thinking about swing blade also - it's nice for small cross-section material, but when it comes to cutting beams the chain or band sawmill would only be sufficient in my opinion.
you might have a point, but you can double cut with a swing blade...8-10" should be plenty for beams. btw...when using dino oil to lubricate the chain the sawdust is only good for burning...with bio oil you can use it in your garden or whatever. do you think it would be possible to use biodegradeable machinists cutting oil mixed with water to lube the chain?
Ari Lehtiniemi You're right! Have to look more into that swing blade sawmill. Don't know about the bio oil's lubrication capabilities but I think it's worth a try.
Nice job, really like it. how did you connect the motor shaft to the chainsaw, it is via the normal chainsaw sprocklet?
Thanks for the comment!
Motor shaft is connected to the bar shaft via pulleys and two V-belts. The bar shaft has an ordinary sprocket only it is bigger in diameter than a regular chain saw sprocket.
Thanks
What a great mill. I am really interested in building one just like yours. The only thing I cannot figure out is how to connect the electric motor to the drive procket. Do you have any plans available?
Rick Rabjohn Hmm. Somehow the comment I inserted a while back doesn't show here. I'll do it again. The electric motor is connected to the sprocket via V-belts. The sprocket has its own shaft I specially made. And that's it! ;) And the pulley on the electric motor's shaft is two times bigger in diameter than the one on the sprocket shaft.
***** how did you connect the sprocket to the shaft? Was it simply welding the right sprocket for the chain to the end of a solid shaft?
Nice job on the mill how long did it take you to put it together
Thanks for the comment!
It was an after work project. I worked on it in the evenings and it took about a month to put together the first 5m long mill. Then I needed to cut over 10m material and built new rails for it. So it took me together about a month and a half.
I'd really like to build something like this. I'm thinking that the frame from an old camping trailer or mobile home might make a good base for the mill to travel on.
I'm curious about the bar oiler. Could you explain how it works? Is it just gravity fed from the tank? How do the fittings attach to the bar? How is oil delivered to the bar - does it just dump out on the side of the bar and find it's way to the chain?
Thanks.
+bruin ruin The oil is gravity fed and goes through a hole drilled in the edge of the bar just like the original one near the saw case if the bar was attached to it.
Thanks for the reply. What about the oiler line near the tip of the bar? I"m not aware of there being a hole out there, is there? How does that one work?
Donn, have you considered a 2nd bar, or a similar thickness metal bar, mounted same height as cutting bar, about 500mm back, so it slides along in the cut that was just made, thus supporting the slab as it goes? I notice in the video that the slab/board sags down after it is cut. Thank you for posting
Nope, it's not a problem. It works pretty good even without wedges and suggested support bar.
+Donn DIY ok cool! Hey thanks for the reply, means alot, cant wait for the next project!!!!
Little slow but is still good cut
Nice simple design. Regarding to chain that you use - is is standard cross cut chain shaped at 30 deg or is ripping chain sharped at 0 - 10 deg? I see that cut is nice and smooth. I will build something very similar but with petrol engine instead of electric motor - greetins from Croatia.
Darko Ljutak I use ripping chain. I would get mad pretty soon if I was using the regular one. :) The chain should be sharp then it will make a nice smooth cut without a lot of effort. I wish you all the best with your sawmill project. The petrol engine makes the sawmill mobile when you put some wheel under the rails. ;)
What material is the track sitting on, sand?
Yup, compacted with soil compactor.
Дуже круто!
Шина з бензопили?
just doing work!!
Yes! :)
Dude you some cash in that one
donald laisure The first time I bought material for the mill I spent 120 euros, second time for the longer railway it added up to 190 euros. In one day I am able to cut material worth ~ 80 euros. I think it's a bargain. :)
on how many rpm did your motor originally work? looks you increased speed 2:1 but lowered the torque for the chainsaw? cheers!
Originally 1440 rpm, I did speed it up 2:1 so final chain sprocket speed was around 3000 rpm. Later I changed the motor to 3000 rpm one but kept the drive.
Great job! I would like to bulid one on my own. But I have some questions about the engine and gear ratio. What is the power of this engine? How many RPM it has and what is the source to out proportion of RPM?
+Rafał Nowak The electric motor is 5.5 kW, final chain sprocket RPM around 6000.
Why did you built a bandsaw mill when having this one? Did you had problems with the chainsaw mill?
Great work on both btw!
I sold the chain sawmill so I could raise funds for going to Australia to work. It was life changing, so totally worth it. Also - I really liked the chain sawmill but the bandsaw mill is much faster. Although the build is much more complicated.
@@DonnDIY cool, thank you for your answer! Like your channel!
This is hilarious because you are milling logs to late 80s or early 90s skateboarding music.
How about some plans to share.Looks very simple the way you drive the bar.
Thanks for the comment!
There are no plans. I made it using what I had and therefore could not use any particular plans. The bar is driven by two v-belts. The pulleys are also homemade - aluminum cast and turned.
👍¿de cuantos caballos de fuersa es el motor? ¿Hp?
I was about to buy a bandsaw, then saw chainsaw bar mills. One question, wouldn't the bar cut both directions ? Or too much chatter ?
I've built, owned and used both chainsaw and bandsaw mills. Chainsaw mill is much more simple and cheaper. But bandsaw is faster. In theory you can cut both ways with chainsaw bar but I personally haven't tried it. If you're interested in another type of sawmill here's the sawmill I'm currently building: ruclips.net/p/PLkmF7FAZBzkWuunWOOh0zSzB1LllQdUKr
how to setup for a oil in front spocket blade you have a model or picture of fitting thanks
How many board foot can you do a day?band how often do you have to sharpen the chain? And could a 14 hp motor run this? Thank awesome mill
+As Dougherty When cutting clean logs I have to sharpen the chain probably only once a day if that. 14 hp motor is sufficient for that application. ;)
how many (KW) kilowatts has that engine, and rpm.?
Great design..
denistuby 5.5 kW, 3000 rpm, chain rotates 6000 rpm.
slick setup, got to be quieter than the gas powered , just not very portable
tim trott I could make a trailer for the mill to make it portable but its cheaper to haul logs home instead of going to the forest to cut the lumber there with a gas engine.
what's the specs on that motor and chain? i was looking at making something similiar. would save me alot of time and failed engineering if you feel like sharing. cheers.
Ripping chain, motor 7.5 kW, motor to chain sprocket transmission 2:1 via belt pulleys.
This is really nice mind if I loosely copy it?
Phillip Bishop Not at all. Feel free to use it!
Sorry I went back n read more comments n you have already answered my questions. Thanks . Are you still running the mill ?
Tiffany Davidson No problem. I'm still running the mill and it works great! ;)
how does the driveshaft of the engine turn the chain
With two V-belts.
Awsum mill could do with out the tunes though.I'd rather here it run.
mohawksniper79 When I made the video I thought it would be cooler to add some music too. It sort of ties the video together.
salut Donn pour le cable de traction comment il fait pour ne pas débarquer des poulies je veux rajouter sa sur le miens qui est semblable merci
Donn sa suudad ikka igatpidi üllatada. Väga hästi tehtud. Mis täpsust hoiab?
Tänud! Ideaalselt siledal raudteel saaks kuskil 1mm täpsusega materjali küll ma usun.
Did I read you are making a band saw as well? Do you wish you had a portable mill?
PJ Jackson Yes, I will rather make a portable mill instead of stationay. It opens up more opportunities.
*stationary
wow, what is this song? i love that guitar
patrick o The song is "Back and Forth - Silent Partner" from RUclips Audio Library.
there are some advantages to this design over building a bandsaw mill in my opinion.... what i need is a saw that could cut sub 8ft in length logs that are anywhere from 24-80 inches in diameter... have been considering using a vertical shaft riding lawnmower engine for power, and welding together two 36 inch bars to get around 70 inches of capacity. such a saw would be really useful for cutting bar top blanks out of the stuff around here that won't pass through common bandsaw mills. what are your thoughts on this idea? i realize it might be slow going, but i am in no hurry.
bob g If You get the final chain sprocket rotate at least over 5500 rpm I think it would be okay. It will take a bit of time but will get the job done.
Just a quick question... How do you adjust the tension on your chainsaw?
If you look at the bar there's a bolt on it. The bolt pushes the bar out and that's it.
*****
Nice! Thanks!! For your little pulley, how do you secure it in place (so it doesn't fall) and make sure the sprocket will turn right? With a bearing between the pulley and the sprocket? Thanks for your patience ;)
Minos Nitrof
Little pulley is pressed on to the shaft. The shaft has two bearings and a spacer between them and they are secured with a nut, the bearing housing is recessed and holds the shaft in place.
*****
Thanks a lot! That will help!
so that bar oil running to bar?
donald laisure Yup, but I've modified the sawmill since this video was shot. I changed the electric motor and added a more rigid frame for the tip of the bar and few other things: Improved chain sawmill
NICE
What size are those pulleys...do you have any idea what your final RPM is? Your chain...is it a ripping chain or standard? Skip tooth? Do you have any problems with vibration or the bar waving in the cut?
The pulleys are 2 to 1 ratio. Final RPM on the chain is about 3000. It should be at least two times more. The mill has a ripping chain and yes it is skip tooth.
I had vibration issues when the chain was blunt or when the bar tip was unsupported.
What's the Power of motor
This motor was probably around 3,5 kW
nice mill design! looks like your bar is burnt, maybe you should consider going with something made of higher quality materials and it will last much longer.
I had problems with bar oiling so that's the main reason for it to change color I think. Otherwise the bar is Oregon and chain from Stihl so they should be good.
Donn DIY what are your thoughts on putting a jug of water on and running a small hose to the bar? I have seen some that use water to cool the bar along with oil.
Brian Teed I think it's a good way for cooling. I will incorporate that system on my new chain saw mill and try it out.
Make sure and post a video when you get the water system set up. Forgot.to say the first time, nice video.
How did you make your rollers and track
+Zack B Turned the rollers in the lathe and welded the tracks together from angle iron and rectangular tube.
+Donn D. Can you take an up close picture of the wheel and track. It looks to be just a wheel with center groove on angle iron, correct? I'm about to build one too.
+Zack B do you make these to sell?
+Zack B That's correct, just a groove in the wheel and it fits on the angle iron. Have fun with the build! ;) This thing will do a good job.
+Zack B Not at the moment, no. :D
thanks for showing how you make wood instead of how you made the mill
👍
Whats the rpm of chain
3000rpm
What is the lenght of the chain guide?
Probably around 70-80 cm.
@@DonnDIY Thank you
When you built this did you use anything to change the speed of the motor shaft to the chain? If so or not do you know how many feet per minute it pulls the chain?
The chain sprocket is sped up two times via belt pulleys compared to the electric motor rpm. The final rpm at first on the chain sprocket was around 3000 with 1500 rpm motor, later with 3000 rpm motor it got doubled up again. Worked well both ways. Don't know the feet per minute unfortunately.
Donn D.
I know you have plans for other projects. How about a set of plans for this?
+Hubert Humes I have had that plan for ages and will do that in the nearest future. ;)
What is the power output ?
Juan Garcia The electric motor is 7.5 HP, but the belts are taking the power down a bit at the final drive.
***** thank you very much for having answered the question I needed give !! and other data I need, how many revolutions per minute should rotate the chain? is cutting wood and with that I will be here eucalyptus short outfit that works on that computer tables for Eucalyptus?
Juan Garcia The final drive sprocket rotates close to 6000 rpm.
Saya mau memiliki satu unit,bagaimana caranya.
what size bar were you using in the video?
Also what size HP motor are you using?
Thanks for the comment!
The bar is 58cm from tip to tip. Actual cutting length is less. The electric motor is 5,5 kW.
if you don't mind I'd like to pick your brain... 1) about how many rpm's are you turning? 2) how wide are your tracks set?
Corey Wells There's about 6000 RPM on the chain sprocket (main motor turns 2 times slower) and the tracks are around a meter wide.
+Donn D. Hello. Verry good work. Im thinking about a similar saw with an 16hd Briggs engin.
I think if the lubrification is good you could turn tehe spocket at 12 to 15000 rpm's
Chainsaws turn 10 to 12000 rpm.
Bobcat Driver Thanks! Using a gasoline or diesel engine is a really good idea. The lubrication must be really good - don't be a cheapskate on lubrication or you'll be buying new bars and chains instead. :D
Paris bataye
Will you?
+Zack B I can do it but I think it goes faster when you order them from eBay. Search for "groove roller", there's a lot of results. ;)
Could have done without the rock concert
