We talked to Woodmizer and they said that the blades shouldn’t be snapping like that. After showing them some pictures of where the blades have been snapping, I’ll let you know what they say.
Em get you a leaf blower that will help blow off your machine. Yall need a stationary fuel tank to fill from.
On my regular horizontal bandsaw the blade will usually snap at the weld.
Hi, Excellent video. Woodmizer may have a solution for the small fuel and water tanks because they do ride on top by the engine.
It really sounds like they failed in the welding or annealing of the weld. Good that you talked to them. I'll bet they have a flawed batch of blades that you obtained. In any event, they should hear about it.
@@bio-techlarry9602 It's possible to add a sight glass to the tank, or I think you can buy a cap with a fuel gauge on it.
Red hair! The eyes, the eyes, the eyes!!!!!! WOW!❤
Yeah, those shocking eyes - Who gets the DNA credit ?
Supermodel/Lumber Sawyer! 🤩👍
Colored contacts??😳
She’s got “tiger eyes” very rare and beautiful
Yea and you can tell she is about as stuck up as they get. Not worth it.
I have been watching on and off for years but there filming is getting better and better.
Get a farm fuel tank with transfer pump & long hose w/nozzle that can be locked up . Check blade temp on occasion w/digital thermometer . PM : Surveillance .
I have to agree with a lot of the commentators the welds were not annealed properly, Years ago in the machine shop we welded the metal cutting blades ourselves, when they were not welded and annealed properly they would break every time. Joe Maine in Georgia makes Wood miser blades for many band saws including the LT 70 series. And as others said contact Wood Miser to inspect your saw in case there are other problems, although I do feel the problem is bad welds. Good Luck hope the problem is solved soon... John Toccoa GA
Keep a detailed logbook with as much detail as possible: Number of cuts between sharpenings; number of sharpenings; tension on each install; type of wood cut; ... anything you can think of. That is DATA. Then discussing the data with the manufacturer can help them help you.
If you're collecting data, type it straight into an organized computer spreadsheet. You never want to be forced transcribe it again.
xyz, that was the best advice you could give Emerald. Data is very important. I'm sure those gals can set up a spreadsheet. Will save money in the long run.
Try some aftermarket blades… sometimes the manufacturers cheap out and overcharge for “ their “ blades…also get an inexpensive 15 gallon fuel cell with a hand pump and keep #1 diesel in it. They are the handtruck type.
There are only solutions.
@@Dadwithallthecool Do you have any after market manufacturers you can recommend? thanks!
@@lumbercycle136 I don’t. Check on the internet. I don’t own a sawmill, I only worked with a friend who had a LT40 and he had someone make his blades.
Despits setbacks i hope you have a great day and enjoy the rest of the holiday weekend.
Hey Em,
Your eye's came on strong in the opening. Reminded me of "Village of the Damned", of 1956 vintage
May be a temper problem on the weld. Something to think about, if it's not tempered right it can't handle flexing as much
Prayers to your customer, that's a painful injury.
Great incitful video, woodmizer needs to check this out.
God Bless folks.
YOUR EYES ARE SO BEAUTIFUL THEY R THE PATH WAY TO YOUR SOUL
Welds are brittle. They need to be tempered/drawn back after welding. The finished weld needs to be heated to a light orange color and left to cool to room temp before filing smooth. You probably know this.
We’ve sawn for a lot of years with a Wood-Mizer. The first thing you want to check is the blade tension. Make sure it is running high enough. These blades are designed with a very high breaking strength. Next, make sure your blades are not running against the back of the roller guides. They should be 1/16-1/8” off the roller guide even when cutting. It sounds like you’ve got stress cracks. Could be a bad batch of blades but doubtful.
You saw mostly hemlock so blade cleaning/lube should not be an issue but if you’re into pine or fir with a lot more sap, you’ll want to run your cleaning solution higher. We have the lube mizer which I can’t recommend highly enough over a drip system. Also, mix Dawn dish washing detergent in with your water. It’s incredible at cleaning pitch off the blades.
It’s possible you may be crowding the blade too much but usually that will show up when you hit a knot with the blade diving into the cut.
Amazon has sight glass kits and fuel level caps to keep an eye on tank levels.
A sight glass would help them out and Gramps is sharp enough to install one. Talk nice to him and maybe he’ll get on it. Lol
Put a clear sight tube that is connected to the tank to show the level of fuel inside.
This is exactly what I was going to suggest if no one beat me to it. An external sight gauge for the fuel tank.
Definitely this.
Sounds like something that could get broken easily with two tank setup. Scale would be nice and grandpa might be able to do a custom one that is easily read from far away.
I'm surprised if the manufacturer hasn't made a digital one for it though.. There seems to be a lot of electronics in the new mill, so it's strange that the fuel and water could just run out without warning.
Emerald, you do so well, it will only get better. Much love
You are a smooth operator!
Oh and as for the fuel issues I’d get a fuel cart or mount a transfer tank to a skid or pallet and get extension lines. If woodmizer says distance or height to draw fuel is an issue then just add an inline 12 volt chugger pump powered when the key is on. 👍🏼
Just use a platform ladder. They have to get the water/lubricant up there as well.
@@scottsoperplatform ladder doesn’t resolve frequent refueling due to lack of volume but I hear where you’re coming from, although a ladder like that would more than likely be in the way. They’ll figure something out they always do!
@@Kwhopperfan I would expect that the mil burns one to one and a half gallons of fuel at full blast. (fuel tank looks to be five gallons) So they don't have to get up there all that often. The storage shed is right there so no problem to get the ladder and the extra fuel tank.
Some really good ideas. I think you need to make a list of priorities. Safety is always #1
1. Fuel and water replacement should be made easier. Pushing tanks over your head to empty is physically not safe. That needs to be changed.
2. Monitoring fluid levels is a necessary task. Ask Wood Mizer for advice.
3. Blade breakage can come from two different avenues.
The guides on the side and rear of the blade should be inspected for wear or damage. Check top and bottom guides.
4.Make a log of each blade’s performance. Add notes as to how it functioned. After you have the data contact the blade manufacturer. Show them your written data of each blade. Ask them for recommendations.
If you can get a few blades from another company. Try them as a comparison. This is good so one manufacturer knows you are looking for better blades.
Teaching wood shop for 42 years. I’ve had two companies I wouldn’t buy blades from again.
Have your data when talking to manufacturers.
Good luck
Suggestion 1: Buy a couple more 5 gal diesel cans and keep them half full. Suggestion 2: Plan to fuel at mid-day every day, with that half a can of fuel, which will be a lot easier to hoist up there.
What a beauty.😍
Many years ago I worked in a high rise office building with a small parking lot Peter Folger parked his car there, he was a nice guy he drove a Mercedes Benz with a rabbit as the hood ornament.
You girls are so smart and pretty. I know your parents are proud of you! 😊
One of my favorite channels on YT!!
I love your passion for technical problem solving.
Instrumentation supply companies sell stick on, outside the tank, fluid level gauges that use sound to detect the level. This reads out on remote digital meter. Good Luck solving your issues.
when i fill the lt70 i leave the tank on top and lower the saw head to the deck and stand on a 6ft ladder to avoid sawdust. also i run at 80psi and rarely get failures.
The on line WoodMizer video says 80psi.
I ran an industrial bandsaw in a machine shop 40yrs ago. It had a electric welding tool on the machine. Clamp em close..hit the switch.. buff smooth
Em, My family used to have some friends that lived in Costa Rica, and they would send us roasted coffee beans. After drinking that coffee and going back to domestic brands was like drinking mud.
there is hope for the future, thank God, keep up the good work
You can install site glass kits on those diesel tanks. 👍
Ya'll are awesome! Thanks for the vid!
So on my LT 40 water tank I cut a neat hole in the top for an ABS shower drain with the drain flange in the tank and a female adapter on top with a threaded cap . Cut two sides flat on the ABS flange to get it in the tank and install with the rubber gasket. No more lifting tank full of water.
Your customer with the disk issue is just representative of those folks that do real work for a living. The good news and bad news is that if they can still function, there is no major problem….even if there is one. An example of this is a 75 yr old friend of mine knew I was going to Lowe’s to pick up a load of 2x12s on the roof of my van. He said he was headed to the VA to see a doc about what he thought was a minor cough, and would stop by and help me. Help to him means doing more than his share of the work and afterwards he goes to the VA hospital. They put him in intensive care for a week with a serious pulmonary infection. Some of these folks won’t quit strenuous work until two weeks after they are pronounced deceased.
I got the coffee !!!!!!
Those eyes

Check the blade tracking sometimes the bolts loosen to check the drive side you need the engine off and the blade engaged with no tension then see if the drive side wobbles when you shake it
I have a hardwood mill gt34 Australian, I had a similar problem with blades breaking out side the log it was a brand new machine and it ended up being the band wheel bearings were faulty even though they felt good .
I also have to say love your channel , all the best from Australia 😊
Ty
We had some not cut straight and binding in the log and that sucked!! It was an LT 70 Wide!
4:01 Wow! Those bicep veins are very noticeable!
One of the possibilities of the band failure is from heat stress. The blade is moving a lot quicker then the old 40. If you have a chance have someone hold a heat gun on the blade to see what the temperature is of the blade as it exits the wood. One of the things I hate is dispensing gas with these new government required safety fuel cans. I bought a small battery operated fuel pump. It pumps 2.2 gals. per minute. Seeing the fuel tank on the new mill is on top of the machine. Your going to have problems getting fuel in it by using 5 gallon cans. With the fuel pump you can put the can in the loader bucket and use the pump to tranfer the fuel.
I put my diesel in a 55 gallon plastic barrel, and have a hand-pump on it, with a hose like at a gas station. Works well, but I don't know if there is a place to put it next to the sawmill that would be safe from getting hit by a log or something.
One just uses another WoodMizer fuel tank for that machine. One takes the empty can off and puts the full can on. not filling the tank while on top with a fuel can.
Get a small Transfer pump. You can sometimes find 12V ones for transfer from tank to tank. Try one of those pumps that install on a drill. Try less tension on the blade and slower feed.
Mark those blades and hours and return to supplier. Possibly a bad batch. Your Butt will be fine!
Thanks for the wonderful information as always love smell freshly cut wood thanks so much
After the lumber and the phone call... They're watching you! Always watching!
Maybe the weld on the blades isn't getting properly annealed at the manufacturer?
just checked it out.... love the shop
Your eyes are sparkling 😍
The sound of power
from the disel engine
as it is revved up high,
the big blade's teeth go out of sight
and cuts through the log
like a piece of pie
The sawdust piles up
and the logs go down,
as Emerald and Jade
keeps the big saw blade
spinning around.
Good job girls.
keep at it lumberjane
Some days are just full of Back and Butt pain...other days are a pain in the Neck.☹️
Time to hit the creek and cool it for a while...👍
For your fuel situation, you should check out a thing called the “Handy fuel caddy.” It’s a US built fuel caddy that looks like it holds about 20 gallons and has a gauge, a fill cap and a hand pump on it and you pull it around kinda like a big wheeled battery charger. I don’t have one but I think I’ll either buy or build one. A plastic tank on something like that would be great for the water tank too.
EDIT: those are ridiculously expensive. Vevor makes one and it’s not exactly cheap either. Maybe a fuel tank from an old swather or something like that would do. Grandpa could probably weld one up for that matter too and you probably have an old pump around somewhere to put in it. I think a 2-wheeled dolly with a tank attached would do the job. I’m going to build one instead.
The "Handy fuel caddy" that I found has a 30 gallon capacity. It may be well built but it comes with a high price. I think I would get a third WM fuel tank for the LT-70 and just keep it simple. The ladies can get the fuel up there just fine. I did see an ultrasonic gauge that might help but again I voted myself down in favor of simplicity and no cash spent.
Omg those eyes!!
It's warm enough for daisy dukes , thank you sun.
"There has to be a bean for everybody" truest statement I've ever heard
Are we not all human beans?
Thanks!

Nice, was afraid you found a tick 😅. Play and have fun 🎉
Hi Lumber Capital Log Yard & it's is Randy and i like yours video is cool & Thanks Lumber Capital Log Yard & Friends Randy
The blade breakage is definitely due to the welding process. I used a butt welding machine in Starretts and if the blades were not aligned exactly the weld was weakened. I used to test the welded blades on a reciprocating machine to determine the quality of the weld.
I hope you are able to find the cause of the blades breaking soon. I mean let alone the down time and the expense of the blade those things are scary and dangerous.
I am happy to hear that Woodmizer has been notified and recognize a problem exists.
Have a great afternoon and an even better holiday weekend.😉
My first thought is the blades are not made right but the tensioner may have a problem as well. As for the diesel a transfer pump is the answer. Your grandpa can fix you up. Little problems add up to a big nuisance. You can get an aftermarket fuel guage. Keep in contact with woodmizer to see if others are having the same issues. Excellent job ladies thank you for sharing.👍♥️♥️
I work with precious metals at work and use a bandsaw for cutting on one casting machine of ours. I have had times where I will go thru several blades back to back. All breaking at or near the weld. Then all is good for a long time. Since I made no adjustment to tension I always assumed we would occasionally get a few bad blades in an order of new blades. It is like the metal just has a bad spot around the welds probably from the heat from the welding process. One time the company bought a batch of blades discounted to a cheaper price from the same company we always order from and every one broke in a short time.
if you have an hour meter you could keep track of that and get some of control on the fuel ,
also large logs take more horsepower than smaller logs that may be a difference in fuel consumption ,it's something to look at ,
watch the break if it's in the weld and still on the factory sharpen ,call them or send it back they should fix or replace it
The blade snapping problem is due to improperly annealed splice joint. When you join the blade together and send an electric current into it, it welds the metal together. When this happens the blade gets cherry red. You then let cool down. After it is cooled down you bring it back to a dull red for 5 to 10 seconds and let cool down (this is annealing). It sound like they are not annealing the blades properly ( joint is too brittal). I do not if this helps or not but I would run the tension at it normal recommended setting.😊
Hi Emerald and Jade If you google why does diesel amount vary in use you will find everything from dirty components, soot deposits on injectors, storage, age, whether it has been treated with biocides. As for a gauge you could use a small short brass tube through a small hole in the lid then a skewer with a cork on the end through the tube, the brass tube keeps the skewer straight.
Oh you girls will know all about disc trouble eventually if you keep up this type of work. I'm only 36 and have two bad discs since my late 20's. But you get on with it. Old boy loading up his truck was probably just used to it by now haha!
One can install a float gauge. Fuel pumps are cheap and easy. Check Harbor Freight.
Try a different blade supplier, If you are using water to lube the blade add sssome cheap detergent. As for the fuel. Put the full containers in the bucket of the loader and lift to the height you need and slide them on. It saves you lifting. Great vid as usual.
I remember back in Vo-Tech school. we had to weld the blades for our steel band saw. Once you welded the blade you let it cool for a few seconds and then you had to bring it back up to just before cherry red to anneal the welded area. if you didn't do it properly it would be too brittle and it would break at the weld.
Use an indelibly pen where the weld is on the blade you use. You can see if the weld brakes as the pen mark will be each side of the break. Good luck and keep safe.
Thanks for sharing 🍸
The placment of the fuel tank seems odd but gravity plays a part. You need a stair case next to it to fuel up.
Give the channel a thumbs up 👍👍👍👍👍👍👍👍
Make some cheap indicator 2 brass fittings, and a piece of clear hose, one fitting on the top one on the bottom, the hose in between.
For the new blades before mounting them on the bandsaw, you may want to anneal the weld joint. To do that you'll need a propane torch. You heat the area of the weld joint until it turns a gun-blue color. Then immediately pour about a gallon of cold water on the heated area until it is cool to the touch. Normally you would drop an annealed metal part into a bucket of water or oil but you can't do that with a large bandsaw blade.
Check the lot number on the blades to see if they came from the same manufacturer run. This could be a problem from the metal prep before welding. The blades are probably spot welded, and back in the day when I was a machinist we also found that the .metal the blades were manufactured from was often inconsistent. We solved the problem by brazing the blades instead of spot welding. If you did braze instead of spot weld you would have to setup the grinder for sharpening starting at the brazing joint each time you sharpened blades. That should not be a problem.
The reason blades break on band saws its because of the bearings that guide the blade are bad just replace them and the baldes will last a long time .. It was happening to my metal band saw and I found a video on line that showed how to replace them and it worked .
Hello. I love your channel and the content. I got a new sawmill about the same time you guys did. The learning curve has been steep but working through some of the same issues. One of the last things I think about while sawing is fuel. I have not run out of diesel yet but have come close. With my old mill, I rarely broke blades. New mill: break several every week. So frustrating. As many videos as you ladies have, you should post one of a blade snapping and the process of removing the blade. 🪚🪚🪚
That is a good idea. Set the camera up and keep power to it till you get a picture of the blade snapping! The show how it is put on this mill.
12 volt transfer pump, set extra tank in wheel barrow
That is the most natural monologue I have ever heard you do on camera. Honestly, sometimes I see you and Emerald a bit awkward talking to the camera. I'm sure the fact that you really know what you are talking about makes it so natural (and comfortable). Nice Job! (I even liked your commercial at the end🤪)
Oh, and about the blade. I'm guessing that the blade goes much faster than before, thus creating more tension. Now the fact that the break is after the "cut" sounds like some kind of dampener misadjusted responsible for softening tension release when the blade exits. With no damping of the release it creates a whip like tension. Instead of cracking the whip, it's a failing of the weld.......(or its just bad welding....HA)
There are so many good suggestions for solutions from great followers in the comments here, it must be because of the beautiful eyes. Wood-Mizer is definitely familiar with the problem of weld seam breakage and can give you good advice. This is a good company with a lot of experience, I'm sure. As my solution to the problem, I would suggest showing Jade's pretty eyes too.
Great informative video
In the old days we would fuel and check the oil every day it's called maintenance
Hard working woman and she is a red head to boot gorgeous ❤🎉
You should be able to setup a large tank down closer to the ground with a vehicle fuel pump up to the intake that runs on DC(battery) or via a inverter. Once you get up to a larger sized tank you might be able to have the diesel delivered instead of having to haul it yourself.
No need for all that.
Back in my day of back injury and back pain we didn't have no stinkin cell phones to interrupt us when we were workin hard. Obviously his back was working when he got the call...Stop answering the phone! 😁
Add a sight tube to the fuel cells.
DIESEL TIPS AHEAD: I'm a part time woodworker so I find some of the stuff you run interesting. It is also nice to see a family working together, About your diesel - there are ways to add a fuel gauge to your tanks, and I think that would be a really good idea. I'm not looking at your setup, so I can't just give you a link to something and say "use this" but ask around and look on the net. You may have to improvise a little but it is doable. I'm surprised Woodmiser doesn't offer an option. Maybe just fabricate a simple sight glass. One thing you want to avoid is running a diesel out of fuel. If you end up with air in the fuel system you may get to learn a new skill - purging the lines. It isn't hard but it can be frustrating sometimes. Be careful if you do work on the engine because diesel fuel at pressure can be injected into your skin, and that is an injury that doesn't really heal. I wish you and your family nothing but success, and thanks for the videos.
Talk to Nathan at Out of the Woods. He has been running a LT70 for a while.
You can see the level through the tank.
If you have more than one box of blades try from a different box to see if problem goes away
And for the fuel tank, keeping sawdust out of those tubes, get a couple of pieces of silicone tubeing that fits tight and put a plug in the other end and maybe a hose clamp or zip tie and your set to go easy peezy 🙃🙃
I had the same problem and it was my blade was hitting on the rollers in the cut and it would snap the blade every time. I adjusted them back from the blade and never had a problem sense.
A simple fix for gas gauge rig up a led bulb on th top of tank, turn on and it will aluminate the inside of the tank.
we are on the same page!
Get a digital thermometer and check the blade temp then find out what the manufacturers temp tolerance is supposed to be for it.
The factory welds may not have been done properly and, after heating up during the cut, are weakened from the heat. This leads to snapping after your cut because it’s cooling down and the weld is contracting, weakening it further and making it snap.
This!
Try running the saw a bit slower and using more cooling water. Blades break when they overheat.
Well for one I really think you guys are great beautiful eyes by the way love watching you ladies and the talks that you have wanted to comment on the blade yeah I think it's just getting too hot maybe it's the cool-down process with the water as well as a lot more power behind that machine putting more torque on the blade and yeah you're right that machine moves fast so that could be a combination of it as well just the blade getting so hot so fast thanks for all your info ladies bye for now😂
As for the diesel better to have it and not need it than to need it and not have it and Grandpa was right the first place you should have looked was at the weld and you Irish girls are the prettiest 🤠🐝
If you add a clear tube up the side of the tank penetrating it at the botom, it will give you a gauge.
Tree sap may be building up on the drive wheels causing an non symmetrical pulling dynamic and tearing the blade from one side.
The blades snapping at the weld does sound like a manufacturing problem. Being from Lycoming County, those mountains look good, and familiar.
The blades are breaking and are probably not lasting very long due to the blade material being out of specification. I would be that the band material in too hard. After heat treatment to harden the steel a second heat treatment is performed to temper(soften)the steel to allow the metal to readily bend and flex without cracking.
Contact the blade supplier to complain about your problems.
Joe Peace
Dear Scott, I think I understand that several blades have broken, and personally, I find that the log saw control is placed upside down, (which can also cause the blade to break) for the simple reason that Emerald does not see the precise moment when the cutting begins. Therefore, it enters the wood too quickly and gives a severe shock to the blade. Reversing the control station could only be beneficial and would increase accuracy, blade life and even working speed. I say this as an old man's advice, because you alone are the boss. I wish you an excellent continuation, and may God bless you all.
