Portable Sawmill Blade Snaps at Full Speed
Тәжірибелік нұсқаулар және стиль
If you want to see a portable sawmill blade snap at full speed, stay tuned. Despite the cold weather, I'm out at my Woodland Mills HM130 where I hope to get some frozen red pine logs milled. After a heck of a lot of pulling, I get the engine started and I'm off and running. I guess the 14hp Kohler was not liking the -26 celcius (-14.8 F) temperatures today. Despite this minor setback, I get down to cutting these frozen logs before long. Little did I know that I would be hearing the dreaded blade snapping sound part way through my cuts. If you've never run a portable bandsaw mill, you likely wouldn't know what hit you if you heard the sound. However, I've had my fair share of blades snap on me for various reasons and now the sound can't be missed. Aside from the headache of having to change the blade, the $25 Canadian cost is a pain in the wallet. Oh well, these things happen and now by watching this video you'll see exactly what it looks like and sounds like when a blade snaps on your portable sawmill. Stay safe out there and keep the dust flying!

It's the cold weather and frozen wood that caused it to break. When really cold steel is more brittle and as it travels on the band wheels it is perpetually bending a small amount. This with the cold snaps blades. Another issue is as blades get dull they develop micro cracks in the gullets. These develope into bigger cracks causing breakage. Proper sharpening can help prevent this type of breakage. As a tiny amount of metal should be removed in the gullet removing any micro cracks. Hope this helps from a old Sawyer that's done this along time.

Good way to spend some time in the woods! I've taken to running synthetic Rotella T5 5W40 in my tractor, atv, small engines, and it seems to make winter starts abit easier.
You were so tenacious with that sub-zero cold cold cold startup. The Woodlander pulls through again.

Thanks again James.
I live in Fairbanks Alaska and got an HM-126 this winter. I put it to use in November and it has been as cold as minus 15 Fahrenheit and only one day have I used it above 20 degrees Fahrenheit. Most days it's been right around zero which is about 18 below Celsius. To start my mill at these temperatures, I have a helper hold the thrott le down about a quarter the way or because I normally don't have a helper, I use some twine to secure the throttle down about a quarter of the way. It normally fires up after about three or four pulls using that technique. On many days it is so cold the grease in the wheel bearings becomes stiff and the wheels don't turn at all or barely turn and the mill slides on the rails. The one day it was above 20 it was amazing to have the wheels actually roll freely!

I’m with ya on holding the throttle a little while starting. I try to do the same and it seems to work well. Thanks for watching and I hope your winter is going well for ya
I'd definitely prefer the starting fluid over all that pulling plus that was extremely hard on your pull rope.

We made buck saw blades from our old blades that broke. The buck saw is a hand held saw I'm sure you know what a buck saw is they worked good for us 🍻
If you know anyone that has an annealing machine, you can have that blade welded back together.
On the cold starting. I do lots of cold weather sawing -20 even -30 if im feeling house bound, I use the exhaust off my skidsteer to warm up the mill engine using a metal dryer vent tube, you could use your sled exhaust. As for that blade breaking, if you listen to the sound of the engine stating to labour just before the break it was because of the knot, and you didn’t slow down on the pushing. But very good video to learn from.

That's an awesome idea! I never thought about the snowmobile but to be honest it sure does give off some hot exhuast. Definetly an idea I'm going to try. I also appreciate the tip about the knot. I went back and watched the video and do hear the engine labour a bit before breaking. I"ll be sure ot keep that in mind when I come across knotty wood in the future. Hope all is well. Thanks again,

Nope all isn’t well, stuck in the house for awhile, slipped and busted my collar bone, had surgery to install a j plate, so, laid up for the 8 weeks or more, but, hey it’s giving me plenty of time to watch your videos and lots of others, and stay out of the public to self isolate. Take care be safe.
Hi Sandy, i really enjoy watching your video, i will purchase a Bandmill soon, and thanks for all your advice and recommandations....For your blade, if you watch again this video, you hear the engine bogging down a little bit, the rpm went down a bit then we hear the blade snap, i noticed it and i wanted to share it, have a great week-end Sandy :)

So it is a couple years now since you posted this video. Any new thoughts on why the blades break? I've been using my Woodmizer LT15 for a few months now, cutting mostly cedar, but a few pines and oak. Seems I am getting a broken blade about 10 logs on average. Not at the weld. First on a cedar where it had a ring around the log, reminding me of where a fence might have once been and the tree had grown around it. The rings were not consistent with any sort of fence and many of the cedars have similar features. No metal in the wood either. Most of the breaks have been on cedar, but that is also most of the logs I'm cutting. Woodmizer factory blades is what I am using. And its pretty warm here, nothing like those cold temperatures you experienced. Learned a lot watching your videos. Thanks for posting.

I believe the blades are breaking because they develop stress cracks that aren't ground away when sharpening and/or the ongoing heating up (expansion) and cooling down
A nice day to be outdoors. I’m inside doing paperwork for my business ( and squeeze in a vid wth my lunch ) minus 13 here today but nice and sunny . I would rather be out in the shop or cutting some firewood. Any way certainly not telling u how to start your engine but I have 26 different small engines in my business. When it first sounds like it wants to start I turn the choke off or at least halfway off . I couldn’t tell if u did that or not . And not sure if that would help or not . And does the cold effect the blade . Thanks for sharing . I can’t wait to buy one!!

Hi Sandy, I have the 126 setup too. 9.9 hp. Thigns were going great this week until I snapped 2 blades. It happened on a bigger pine log. I knew the blades were struggling early on. I had gotten them sharpened but the dude did not adjust the teeth. The mill started to shake even though I mill real slow. From your experience do you think poorly set teeth and aging blades are more prone to snap. Tech support at woodland mills wants me to check alignment of everything even to the point of ensuring the clutch is parrallel to the drive wheel using a steel bar. Anyhoo im still learning but your opinion would mean the world

Hi Paul great to hear from you. I"d say if the teeth where not set correctly the blade could've also caused wavy cuts as it pulled one way or another. I'd also imagine that if the blade was breaking it could've been caused by stress cracks in the blade. From what I know that could be due to stresses put on the blade like overheating and things like the full tooth not being lightly touched when sharpened.
looks like fun,arkansas Rob

Hey buddy how are you? I’m thinking super cold!!! I’m glad your safe, the blade was contained inside the machine. When its this cold no bugs hehe! I was thinking what to do with the broken blades. How about cutting to 6 in length stack them maybe then weld into a block and hand forge into a cool Damascus bush knife. Super neat use of the blades. Oops dreaming again hehe. Thank for the cool video. Have a good one buddy

I just had my blade jump off my Hm126 before I cut the log. Apparently it hit the blade guard and took out a few teeth. Removed the blade and now I can’t get it back on the wheels. Ever have that happen where the blade won’t go back on easily? All blade tension is released.

Band blades can be rewelded but requires a special type of welding machine. It can be done by hand with silver soldering but is very tricky to get adequately square and straight with mixed results of it properly holding.. Long as teeth are not damaged you can send them back to manufacture for rewelding and sharpening for a cost of course.
