Take a look at Matthew Cremona sight 😊he uses all carbide blades buys them from wood miser he frequently has nails and it goes thru them and keeps cutting. I am sure he would respond to you.
On your previous video I provided the information to your closest resharpening company that can keep those blades up and running without having to replace or throwing them away, give them a call before you discard the idea of changing over.
When you and your sister installed this blade I noticed you didn’t adjust the blade guides or the blade depth rollers , these carbide tipped blades are not the same thickness and proper adjustments are a must for optimal performance. Not only have I seen boards with scalloped cuts across the boards every half inch or so but you mentioned that at times the blade will dig into the wood when dulled by a nail, these blades if properly installed, can handle most common nails without damage. I would suggest that whomever does the maintenance on this machine pulls out the manuals and go over this machine and set all the required points for better performance.
On your owners manual you will find this note:
Make sure the blade screw in the top center of the C-frame is 1/16" (1.5 mm) away from the blade. If not, loosen the nut and adjust the screw as necessary. Check the screw every 500 hours of operation. Failing to maintain this adjustment will lead to early blade breakage.
I hope this explains what may have caused the breakage.
I don’t think 🤔 I would make my decision on one blade
They make welding machines for band saw blades. Look into them.. you might be able to extend the life of a blade with a simple weld. We did it in a woodworking shop and they have machine for the bigger blades as well. Good Luck & stay safe..
After years of using standard steel blades on my band saw I bought a very expensive carbon tipped resaw blade this winter. It cuts through walnut and Pa. Black Cherry like butter. Very smooth and the finish cut is very fine. I’m sold.
Thanks Emerald, sad that it broke, could have just had a defect. But you never know. Be interesting to see how many hemlocks it will cut, if it would go more than a week then it would be fantastic. Thanks to Jade for her camera work and you ladies have a great weekend! TTFN
You may find that you need to run the mill feed a bit slower when using the carbide blades. If you get a spot welder from Granger or Harbor Freight, you can reweld that blade yourself. Grandpa should have no problem with that.
its pretty difficult to weld up a blade and have it perfectly straight.. also i think from what she said about the weld being on the other piece its in 2 pieces and you can see its bent so .. hey it happens .. i wish she mentioned if other blades have snapped on them.. i'm sure they have.
When you weld a blade together you also have to heat the weld up to around 1200 degrees to soften it so it is flexible. If not it would just snap.
@@mgbill793 you aneal it
@mgbill793 Back in 1967, I was a machinist in a shop back in New Jersey, and we spot welded bandsaw blades often with no problems until the spot welder ceased to work. No breakage problems with blades. After the welder broke, we brazed the blades. That worked well also.
@@mike97525 yes, that is the it.
Geez this family is great. Emerald always has great commentary. Jade and Emerald work like a machine!❤
Uhhh.....yes. I have been using carbide tipped blades for right around 50 years and it's not in question anymore. The same shops that should be in your area by the dozens that can sharpen your carbide blades can also reweld them if needed. Cost should still be a tenth what a new blade costs. For that reason alone they are the smart purchase.

@@Islandwaterjet Texas - standard carbide blade sharpening is by the tooth and geometry but a 30 tooth rip blade which costs ~$100 will cost ~$0.50-0.75 per tooth to get sharpened and I havre some I've had sharpened 7-8 times. Someone doing enough bandsaw blades to put in the automatic feed advance sharpeners will be getting roughly half that per tooth. The only $30 blades for my bandsaw (18" Jet) are plain steel (no carbide). I sharpen them with a Dremel and chain saw stones once, in situ on the saw, and then toss them.
@@Islandwaterjet $25 for a blade that large?
Are you sure they are carbide?
Stellite is far superior and more likely if you have been using for 50 years. As for sharpening. Wet grinder is the only option.
@@jamesoliver6625 in another 50 years where will you be ? Heaven or hell?
Blades develop cracks in the gullets due to all the flexing take place. You can run a blade for a full day and it does not go dull, but cracks form. If you are planning to use your blade to the fullest, you must only put around two to three hours on it even if it still working fine. The sharpening of the blade incudes the removing of material in the gullets which removes these cracks.
Your presentation of evidence seems to jumbled up and mostly anecdotal. How many board feet did you cut?. Carbide blades cut tool steel. You need to bring in a blade expert to optimize your setup. You might want to speak to Bahco rep and see what they have to offer. Lennox also has great blades. You need to do some math in order to determine efficiency
you dont weld your broken blades?
I occurs to me that buying your favorite blade in bulk rolls, then cutting to length and welding onsite might be an answer since you do a lot of processing with the same machine. Grandpa might even go so far as to cut out bad sections and splice 2 resharpened sections together !
That's a good idea. That would reduce the cost per blade significantly, and not thar hard to do. I suspect there is a fixture available somewhere that would make that relatively easy.
You should be able to weld it back together ❤😂🎉😢😮😅😊
yes it should be reweldable if the l the base metal is steel. carbide is typically braised with flux. technology keeps changing np .it might be different
Great update! Thumbs up! Jim
Enjoy U'r weekend. Greetings from South Africa.
A full day of Hickory is probably equivalent to 3 days of Hemlock so essentially you got 6-7 days before it broke. I would say you should be using carbide, also you can use a dremel tool with a diamond wheel to resharpen them.
I was pretty sure the carbaide Blade would last longer, some fire companies have carbide chainsaw blades, because they last longer and dont dull as much cutting threw nails etc. This video was very interesting to watch for me
I would contact Woodmizer customer support concerning the blade break.
They are not going to do anything other than make excuses or blame it on improper operation...
I held off on my opinion until you had your own experience. Essentially, your experience is mine. It's a nice treat to run a carbide on my LT40, and I do keep a couple on hand for special situation logs, but for daily use, I can't justify the cost.
If You take into consideration the extra downtime to make the changes? I am not familiar with milling wood or steel or other metals, but often we do not take the cost for downtime due to tool change and set up, time is money and every minute that the mill is not cutting it is just another bucket of money going to waste.
Question...
Are you running the blade at the same speed, and feed rate as normal blades.
Do you have the option to increase the speed ?
Might be the reason the blade broke 🤔
It is easy to tell that you cut hemlock a lot , it cuts like butter . You can get away with running a blade a long time .
Most blades new or after being sharpened should only be run 2-3 hours before they should be sharpened .
I have not tried carbide myself but that seams like you were pushing a dull blade to far .
Just my opinion from my experience .
Seems a lot of comments are generally suggesting the same thing, but carbide in rolls, weld it yourself and sharpen as needed. From my understanding you will be looking at spending hundreds as an investment not thousands on a welder and sharpening. Don't know about the rolls. But, of course, run more tests then run the costs and see what the facts say in your particular case. You guys are smart you'll figure it out.
You are very informative and talk at a level normal people can understand...we love you from Powell River BC Canada
I see a lot of post on welding blades. I would like to learn that. And how to sharpen a carbide blade.
I would bet my socks that it was metal fatigue that broke it. It happens when you use it more then 3-4 hours a day. In Norwegian we call it "metalltretthet". the metal gets stretched and needs to rest for about a day for not to snap and brake.
With the production of industrial diamonds, the cost of diamond cutting tools has come down dramaticaly. Today, diamond blades should not be that expensive and should outlast conventional carbide blades by a long shot, making them a viable, cost-effective solution to carbide blades. Your test should tell you which way to go as to cost and longevity. Kind Regards,
Dave
my question for emerald and grand pa. what sharpener do they use and what kind of wheels do they use what kind of wheel deesser do they use depending on wear on the grinding wheels.
Isn't vibration an issue with diamond?
@@mrwaterschoot5617 Did you not notice? THE BOSS MAN shut the post down. No new post today. Definitely not getting an answer from Emerald or GrandPa. The Boss Man is back in control.
it is what it is. i am looking for knowledge for me when i get out of forced retirement back to the land i loved for over 50 years. i apologize to the boss man. emerald is one of his jewels and possibly grand pa got called to heaven. if that happened a lost of a good father takes time to heal. you lose the mortal physical body, yet their spirit continues to live in out souls. i know first hand my dad got taken 11 years ago. and on tomorrow may 24 my brother left earth for heaven. he chose 4 days of hospice care and a guaranteed death sentence. than taking life extending dialysis and feeling his body deteriorate until it failed later. he had complications of high blood pressure many years ago. the meds prescribed were not kidney friendly and eventually the kidneys did fail. it took a long time and medical professions prepared for that day and set up a port for dialysis and a possible kidney transplant. my brother eddie is ab+ and i got the ab- version. we were lead to believe that my rarer blood type would kill his rare blood type would kill
ab+ type makes less than 4% of the world population and ab- and ab+ combined is still less than 4%. one fact is ab folks can only donate to ab folks. yet they accept from a, b, and the universal o folks. my mom is a or b and had female plumbing issues and was within hours of going to heaven for severe blood loss. with the help of surgery and blood donations. she survived. my brother and i became blood donors in the late 1970s or early 1980s. he and i 250 miles apart donated over a 100 gallons of blood each in our life time. eddie did it the slow way with the 2 hour long process of draw and spin and extract plasma and other blood components and return the rest back. this allows every 4 weeks donation. i donated whole blood which is a 15 minute donation time and a 15 minute recovery and rehydration time and a rest bit before moving on. a whole blood donation is quicker but it can only happen if you build up the iron in the blood and all is well . but it requires about 4 months.
eddie was and i still am alive as organ donors.
mom is still alive at 88 with memory care issues.
my public service announcement. donate blood if you can. become an organ donor for after god calls and takes your mortal life. if you have a family member in need of an organ and you have a two of them check to see if you can donate one. it could be a gift of a longer life on earth. instead of letting your mortal body return to dirt. consider being an organ donor and/or donate the mortal remains to science. when they are done they can have the remains respectfully cremated and the ground bones and ash returned to earth. yes it depends on your spiritual beliefs and the necessary healing for your loved ones left behind in your life and legacy as you transition for eternity.
Bandsaw blades are very easy to weld.. Just have it TIG welded, grind it smooth and you're good to go.. Any Machine shop or Welding shop should be able to take care of it in about 2 minutes...
Only thing is though usually teeth break when the band comes off or breaks. I think from hitting metal that brings them to an abrupt stop. Worth checking the blade though in case I guess!
@@isaiahshaffer HUH? "usually teeth break off when they come off or break," I'm not that advanced...
@@twistedhillbilly6157 sorry, I worded that poorly. Every time I have a blade break or come off, there is usually broken teeth involved too from the blade hitting the metal inside the covers after it comes off 😂
Love the shirt Emerald 😊
I'm snort laughing watching the safety barrel walking across the yard on your web site. Nice!
You should consider longer videos than 4-5 minutes
From today's comments and some of your previous, maybe going through and checking all your mill adjustments plus look for worn parts, eh?
Simple learning curve for them, Unless we were there and saw what happened fist hand we have no idea of what caused this happen. The breakage could have been caused by many factors including a defective blade.
So sit back down in your easy chair and take another sip of whatever you are drinking and enjoy the show.
Em, you can probably fins a diamond wheel for carbide for around $40- $50.
0:14..........👍
I thought the carbide tip blade would last longer.
I'm sure there are fans below with a lot of knowledge on this subject.
Great channel Em..........learning so much.
Whadda ya do with hemlock ??
You are looking pretty all in blue 👍
Good teaser! Watch for next time. Maybe Woodmiser can take a look at it and help diagnose why it broke.
I was disappointed that you did not show a good close up of the condition of the cutting edges on the blade. Regardless of why it actually broke, Roland Pinette seems to have it covered, it would have been good to examine it for wear. Is it possible there is metal in the log that broke it? Carbide is hard enough to just cut through small pieces if the feed isn't too high. About sharpening, investigate CBN (Cubic Boron Nitride) wheels instead of diamond. It may be a better value proposition.
Check the broken blade for gullet cracks beyond where it broke . This maybe a indicator it’s time was over anyway. Be safe
Maybe because the carbide blades are sharper and cut through wood easier, they don't require as much tension put on them to cut as bimetal blades do.
I just looked up the price of a diamond grinding wheel and the 5" is $180 and the 8" is $350. That does not seem that bad to me but hey I dont do this for a living.
And if properly cared for the wheels will last much longer than a regular aluminum oxide wheel.
Dam technology
That is a fair assessment of the blade’s performance. The probability is high simple metal fatigue killed your blade. Track the performance of multiple blades and compare them to the longevity and speed of the blades you normally use. The numbers will tell you which blade is the best investment. It is called a cost benefit analysis.
why dont trees just friggen grow into precut 1/4 lumber? damn trees.....yu should marry that tree first before you are huggin all over it.
❤❤❤💥Emerald💥❤️❤️❤️🇨🇦
Too bad it broke might of got the week out of it ❤🪵👍Have a wonderful weekend everyone 😉
All you have to do is weld it back together, grind it smoothly, and put it back on the lt 40. When I was 18, that was the job I did. It's was for cold rolled steal, not wood, however.
Peace and Ahev
"diamond wheel" could also mean an MDF wheel charged with diamond polishing compound, though.
I said that one good thing you have to something that make sense yourself working on crafts for wood amazing wondering that's awesome
Is it possible that you had a bad blade?
Nature conservationists have anti logging laws , especially for people who benefit from cutting trees 😀😀😀😀😈😈😈😉
Hello Emerald from Sydney Australia.
Are the rollers inline?
🪵🌏
Based upon the previous comments, please continue to experiment with the carbon blades and let’s see if we can zero in on the problem; there’s some valuable lessons to learn here.
You also have to admire woodmiser for donating the blades, that makes this experiment very affordable!Reno
We welded our blades together ourselves in the machine shop I worked at. The blades came on rolls
Weld it back together.
Thanks for the feedback. Your shirt cracks me up too, lol.
If it cost twice as much but last over 2 times as long it seems better. The softer wood will saw better for a longer time. Excellent video review ladies thank you.👍♥️♥️
Although you do come off very intelligent very knowledgeable
I'm surprised Woodmizer sent you something for free! I suppose you guys have enough exposure to plug their name, they felt it was worth it to them. I bet its breaking is part of their designed obsolescence. That's how they are going to make more money by making people buy more blades. It probably took them 6 months to send it to you too. I speak from experience here. I've owned a Woodmizer LT40 since 1996 and I've learned Woodmizer gives nothing away for free their service is horrible and it takes forever for them to ship parts (at least from corporate) I hate how they disguise part numbers so you have to buy service items from them. Anyway, I do love their mills, however.
Emerald tell your Grandpa he can use a green wheel to sharpen Carbide cheaper alternative it will break down a lot quicker though. But it might just get the job done.
Yes green wheels .. I use them.
Call or email the MFG for an explanation … give them a chance to resolve the problem or work a solution so it doesn’t happen again. They my in fact replace the blade free of charge… Include with your email any Id marks on the blade as the problem might be within a batch of blades that they might be aware of. Include a link to your video here as an easy explanation…as otherwise, you praise the blades performance… I am sure they will appreciate the things you say here…Regards Gary
Blades snap all the time, it’s not that big of a deal
@@lumbercapitallogyard oh I didn't know that...sounded like it was a surprise to have happened...Like you channel ...watch it to relax, Emerald makes it interesting.
Company I worked for added ice to the lubricant on metal saw. Later that saw was running almost 24/7 and they decided to installed cooling unit for lubricant to keep a whole 250 gallon IBC around 5*C
The reason is, the hot blade expands and softens making it dull a lot faster
Every time she says "perfectly" or "perfect", take a shot! 😳
LOL - I love that shirt!! Don't throw the blade away. Especially if there is still life in it. It can be easily repaired if it broke clean. All it takes is a TIG welder and 5 mins. They can also be brazed. I've repaired them both ways with broken and cut blades quite often with no issues. Some blades would have multiple joints where we replaced sections of bad or missing teeth. Personally, I would invest in carbide and the ability to sharpen them. Although the initial cost is greater, carbide blades have longer life expectancies with lower overall lifetime costs when properly maintained. Often we the reason we tossed blades wasn't because it couldn't be repaired or sharpened, but because it would wear to a point that it was too thin to safely use. Good luck. Love seeing a family business thrive. Especially in this economy.
It cannot be easily repaired, if it could be, I would’ve said on the video
Send it back to get welded . Check with a 10x eye loop for micro fractures on the metal blade . Check your guide tensions for clearance . Carbide on wood is the best investment for you guys.

#woodmizer
Great video girls
Very informative and interesting
Talk with Woodmizer and see if they have any special recommendations for feed and speeds. It might be different for carbide teeth blades.
So many gimiky products like that out there. I’m a carpenter and have tried lots of “stud locators” …..no luck, just junk!
Bottom line, is it worth the extra cash? Stay tuned folks. LUVUGUYS.
❤
All handsaws will break from fatigue. You can turn on machine and never make one cut and it will eventually break . Unless you remove stress cracks in gullets rewelding wont work
HI Jenny iv looked them up the most you'd pay for a diamond sharpening wheel $ 300 odd ??? btw just blame karen lol
Lower quality of steel on the carbide blades, them not using HSS on them is a problem.. delt with this shit before!!
give that to your buddy that makes knives.. if he has a forge.. he can chop it into 10 inch pieces and stack them up to make some knives.. hope you enjoy your weekend :o)
😆Love the shirt! "Don't worry I hugged it first" That's great!
Yep..Boss Man needs one too;)!
I have a question. Why are the boxes for honeybees always made from pine. And hemlock is better in the weather. Is the cost a big difference. Thanks in advance.
Had to say what I had to say doesn't sound like a community for me I don't know maybe people have gone too far commenting on your looks. but miss spelling or punctuation instead of a put down maybe you could use it as a teaching opportunity
It's been my philosophy that if an item is "man-made" it can be remade. As several commentators have stated, reweld the blade just as the mfr'r did.
Lol I didn't subscribe to your channel a year ago felt like it was more than a year ago because it made me feel creepy to watch to be honest I thought you were being exploited
People don't use regular steel blade on circular saws I would think carbide sawmill blades would be superior
I do not know anything about milling logs, but I am learning stuff I never knew. Thank you.
The carbide portion of the blade is just the cutting tip the rest of the blade is the regular spring steel that all blades are made from. the carbide tips are brazed on to the blade so the fact that blade broke was not the fault of the carbide.
You can buy " green stone " grinder wheels.
I sharpen carbide stump grinder and lathe tools no problem.
Cost $100+- for a bench grinder.
Must say " Green stone" which has diamond dust.
Don't breath dust.
Machine shops supply has them .
hello lumber it's is randy and i like yours video is cool thanks friends randy
The BOSS must be very impressed with Emerald and Jade.
reweld it , grind it smooth and have another go :)
Please put the thumbs up & down along with Share back to the right side
The carbide blade can be welded with a tig, then the excess material can be ground down by a hand grinder. Any certified welder can do this. It's a 10 min job
I think you lt-40 mite need some work done on it. It looks like it’s done a few miles so dont keep using your carbon blades until you know your machine is up to scratch and you should get a diamond wheel grinder they are worth it not expensive they last long time. Plus you can wield the blade back together
Ha! Love your shirt, and it looks so good on you Em.😘
Just weld it back up and keep going. I do CNC work and I only buy Carbide tools, they last multiple times longer than steel.
Use a GREEN STONE grinding wheel to sharpen Tungsten Carbide, they're $25 apiece. To fix a broken blade: Grind the ends 90° or square, then angle ground so the 2 halves come together nicely with no additional thickness. Then, mig weld, braze or even solder together. Be careful not to heat up the blade too much by using heat sinks but then after the welding, anneal the area by heating it and slowly slowly cool it down. ben/ michigan
wonder if you could make bow saw blades out of it.. drill a hole in it .. probably
Thanks for the tech followup!!
👍🧙♂️
Blade can be welded if not bent to bad to be straighten .
Might be worth doing .
Keep up the great work .
Keep the sawdust flying .
Are the teeth still sharp? If so, you can contact the vendor, describe the blade tension, feed rate and speed you used to see if your settings were good or at fault. Also a good look at the failed blade ends ( under magnification) can tell you a lot about why the blade failed. Good luck, but remember that luck improves with increased understanding.
Time for Em to learn how to weld the blade ends together. As manufacturing cut costs so do the carbide blades. It's a great market for a much improved Milling blade.
I hope she reads the comments. There are an incredible amount of experts on here.
