You're problem isn't "bigger wheels, tension, or tracking" It's alignment. If you look carefully you will probably see your bandsaw wheels are not running perpendicular to your travel. In other words the axis of the wheels don't match the axis of travel closely enough. When the blade enters the material it is NOT cutting parallel to your tracks. Put a good quality square (duct tape it if you have to) on the horizontal part of your carriage with a small gap along the vertical axis and run your mill. If you see that gap vary in or out while pushing on your saw you have your culprit. (operator error) and your blade isn't set level in relation to your track. (your saw can sit out of level as long as the blade and track are on a parallel path unaffected by operator pressure).

One more thing. I see the one log 9:00 in is pretty heavy. If that is bowing your log deck your saw won't cut straight. Even though the deck only bows slightly in the middle, the blade will dive down until it can't maintain that path any longer and it will fight to come up again and pendulum infinitum.

Good comment. When I used my version of the saw it was on a concrete driveway with custom made spacers under each cross piece to make the rails perfectly level. The16 inch diameter log weighed between 600 and 700 pounds and the saw cut it fine into 1 inch and 2 inch slabs. Stephen Anderson

It looks like you only have 2 bolts on each side holding the vertical posts in place. You could test out my theory by removing them and putting 2 thin washers INSIDE at the bottom 2 holes between the square tube and the bracket (so that the saw head will lean back) and make a cut. Washers will likely be too thick and probably cause the blade to pitch up initially instead of down but if you have scrap roofing tin or flashing and tin snips you can shim the posts until it cuts straight. (but you should still drive a nail in one end of your wood rails and tie a piano wire or even heavy nylon thread and make sure your rail doesn't have a dip in the center) a string line is too heavy and won't give you the accuracy you need. If you have 2 more of those corner brackets add them to the front side and if necessary put your shims at the bottom in the rear, and at the top hole of the front bracket. You can try to double check by putting a framing square on your rail and remove the blade guard and see if the faces of the wheels are perpendicular with the rails.

I'm impressed with your boldness to post a video showing less than sterling results. Your perseverance is a characteristic I hope you maintain. You'll get it right, I'm sure.

That is an impressive sawmill build! Great job, Dennis! Here's my troubleshooting checklist for wavy cuts: 1) Dull blade (This is by far the most common cause of wavy cuts) 2) Blade tension 3) Pitch buildup on blade (friction creates heat...blade expands and loses tension) 4) Alignment issues (Don't obsess over alignment issues until you have addressed numbers 1 through 3)

This is exactly what I would have said. You can also add travel speed to the list. With mills with low HP and light cutting heads, they can travel all over the place. Don't get discouraged. Even high dollar production mills require tuning to get them trued up.

Cooks Saw in Alabama is an incredible resource for blade tracking and so many other issues. They post tons of articles with in depth research on sawmill design and why they do everything the way they do on their mills. I have bought parts from them to build my own mill including blade guides. Good Luck! Keep up the good work!

It's really cool how you got it to make perfectly wavy boards!!! :D

Great choice of tunes on log loading, made me think of abbot and costello watching you two. Fun video, Thanks

Thanks, best of luck in the future.

if the blade is wavy, you must tighten it more And the wheels don't have to be bigger, you just need a tensioner

Make your guides adjustable that’s a lot of free float room between the log and the guide wheels

Dernnis did u understand why the blade guides need tobe closer to the log?

I had such high hopes for turning that tree into some good lumber. 2.0 is going to kick butt for sure!

Nice try and Thanks for sharing

A couple more thoughts. I am thinking of changing the tensioning crank by extending it past the yellow housing and making the crank about 12 to 18 inches like the one on the Harbor Freight saw. This makes tensioning easier. . I am also thinking of changing the handle. If some day the threads strip I may make a new screw using and Acme threaded rod. The handle works great when sawing, but you have to step in and out of it when starting the engine. I have not thought of a better design yet though.

i needed laughs, Den delivers

The ocean wave sawmill, great learning experience.

You may have gotten figured out buy now. You have two main problems (1- Your blade guides need to be adjustable, 2- You need to be able to level your log center, the piff. ) don't try to push the blade down with the guides. you need the guides to be on top and bottom of the blade with about 5 - 10 thousands clearance and the thrush bearing just touching the back edge of the blade.

I was impressed. I didn't think that little saw could cut those logs. Fir and soft woods are easier cutting. Plus no knots from limbs. Forgotten about them. A buddy has a Woodmizer. Soap and water is what he uses. He gave me a few tips. HP, Sharp blade. Alignment. Constant speed. I was still impressed. Good job. You said you were going to build another. Build it heavier. More steel. If using wood for bed use beams for sleepers. One of my old customers had a resaw.

Always a good sign when you have gaps between the blade and the log when you pull the head back on the return.

You can have everything perfect and a band blade can still deflect over or under hard spots in hard woods. # 1 you have to get the rollers close to the can't / log, and the rollers should be adjustable to guide the blade parallel with the saw bed. # 2 Blade has to be sharp and the set of the teeth must be correct, If you get a lot of dipping in your cut it can alter the set of the teeth thus pretty much ruining the blade, as it will never cut straight again after the set is altered.

First, check your blade speed. Cooks Sawmills has a really good video on this. Second, adjustable blade guides. You don't want a lot of spacing between the guide and the start/end of the cut. Third, I can't tell for certain, but it appears that your blade comes off the wheels and goes straight across. The blade should deflect downward, through the guides, by about 1"-2" when it comes off the wheel and have to deflect the same height back up to the idler wheel. This helps with tension and also ensures the blade tracks following the guides and not the wheels. Fourth, tpi. Ensure that you have the right number of teeth per inch for the size wheel and speed you are running. There's more to building/running a sawmill than just putting a blade on some wheels with a motor. Fifth, blade width. See #4. Overall, your concept is excellent. Yes, you do need to make some design changes, and I really look forward to seeing version 2.0. kzread.info/dash/bejne/aK13vJuSfdaWmqQ.html This would be a good place to start.

Good ideas. I agree that the blade needs to deflect down onto the guides but an 1" to 2" is way more than recommended by most blade manufacturer. Timber wolf blades has a good explanation. I run about a 1/4" deflection. Blade must be aligned absolutely flat.

Don't give up on the sawmill it is a great design. Here are some of the things I have learned from using my version of it. Blades have to be sharp and correctly set. When I first used mine it cut perfectly. Then I ran the blade into a metal log dog which ruined the sharpness and the set one one side. I put on a new blade and it worked again. I welded a nut to the end of the tensioning crank so I could measure the torque. I found that with the turning torque between 15 and 20 foot pounds and a new blade it cut fine. I am going to increase the length of the tensioning bar so I can easily get more tension. I used a $29.00 foot pound measuring device from Harbor freight to measure the foot pounds of torque for tensioning. That and a 1/2" wrench works great. I also do not use water. I think this causes the drift by gumming up the blade rather than keeping the blade cool. Water also destroys my steel bearings. I considered using stainless steel bearings, but at $6.00 each I think I will stay with the $1.30 steel ones for now and just replace them. I felt the blade after cutting the 16 inch ash log shown in my channel and the blade was cool. I do use 1 inch custom made 2 tpi blades that I get from a local saw filing company. They are cheaper and better than the Grizzley ones I started with. They make them with any tooth pattern and length you want. On my version of your sawmill both of the wheels can be tilted in both directions to adjust tracking. I can adjust tracking after tensioning which helps a lot in keeping the cut straight. If you change yours you only need to make the blade guides on one side adjustable from side to side as the log will always but against the stationary log dogs. I also use 3 bearings with the 1 inch blade. If you have any questions just ask. Hope this helps

@WhatDennisDoes

Thanks Stephen, this does help a lot. I still like my blade guides too and the fact that the bearings are basically consumables. Maybe I haven't found the right blade yet. I think I need wheels larger than 12" in any case so I've ordered replacements. I would love it to cut straight even with a slightly dull blade so it isn't as finicky. I will make a movable blade guard and I'm thinking maybe adding two vertical members to the carriage. Mine is more flexible because of the gauge steel I used. Finally I will weld up better rails that will have built in log dogs. I need to make log handling easier and faster. Since I have a trailer now I can add these things that would have made it too bulky and heavy to transport in my pickup.

I hope to do a video on the fine tuning and blade adjustments and tracking on my saw when I get the time.

I had same problem. In my case i had to change the blade more often and sharpen them corect and also "Wikk" them

What do think about a wider/heavier guage blade with cleaning and cutting teeth like on your chain saw?

Thank you for your videos. I am thinking about building one. Don’t you need 3 blade guides on each side? What horsepower is the engine? Do you have a video of what you would do differently?

Is the 2x wooden frame doing any flexing under the weight of the log and stress of the cutting ? also did you level and square it up it or just set it down on the ground and leave it at that ?

Bandwheels square with raíl and log supports, the saw must run parallel, if so, try without guides, if the cut is up, set the other si de a little more, ( down), you must see it when the cut starts, excuse my english, greetings from Jalisco México.

His problems have nothing to do with deck alignment compared to cutting head alignment. If that were the case, you would see the same deflection across the entire cut. His issues are wavy cuts. Look at skipper s comment. He is exactly right.

Self adjusting blade guides would solve most of your problems. Have a roller that runs along the log ahead of a free floating guide on a track (rail). Will have to use springs to push the guides together as the wheels tract down the log ahead of the blade guide. Its not as complicated as it sounds. There's a few video's that give different example's of different design's. Some quite easy to build. But, it would solve most of your problems. Also, using water on a high carbon steel blade is not a good idea. It will destroy the blade with rust. Increasing the RPM's & properly curing the log (reduce moisture) should prevent guming up the blade. Lastly, increase your mill to at least cut a standard ten foot plank. Might have to make it 12" (or so) to fit the mill itself. You have a really good starting platform though just a few fine tuning designs & you're there.

This is a really neat idea I'll have to look into it!

once a blade starts walking on you, its shot... i re-saw a lot of hardwood.. as long a s the blade doesnt get pinched while running it should last a a long time - support your offcut... i keep spares though....

What you could when you get around to fixing your guides is to try two rollers one over the other and run the blade between them Or make a slotted guide and keep the roller . One of the main things you will have to do is make your guides adjustable sliding forward and back and for slight adj. up and down .

I used to work on a welding shop. We had metal cutting saws that looked similar to yours. We had blade tensioners that would tighten from the top against the blade. They were just rollers that put some tension into the blade

Hmm, interesting!

Overall the mill looks like it works pretty well to me Ive been a boater my whole life as i grew up in South Florida and ive completed several Trips to and from the Carribean islands and then some and i actually did take a sailing class and a Scuba Diving Certification class in College. My joke has always been that in Sailig class they taught us if you cant tie a good knot tie plenty of them i did do Woodworking professionally and as a hobby for over 20 years most. Cutting mishaps and problems are usually a result of a dull or overheated blade on a band saw. Tension is very critical as elll as not forcing the saw through the wood You can usually build a pretty simple jig to hold a Drexel or Rotary tool at the correct angle and pass a blade thru the jig to sharpen. Each tooth one at a time using either a stone or a grinding wheel on the rotary tool i know that Harbor Freight and Ebay sell pretty reasonably priced made in China kits that include the tool and there are a few different designs on KZread channels i imagine if you got creative enough you could build a sharpener that works with the blade still installed on the saw ? My personal experience in blade sharpening is that just a “ touch up “. On each tooth is better than nothing and a high precision is not really needed unless its for certain hand tools like chisels and planes of course i personally will almost always purchase carbide tipped blades whenever available as ive found Over time they pay for themselves and just. Do a better job

Sharp blade. Increase set. Increase tension. Move blade guid. Soapy water, yes! When all else fails...I like a chain saw blade 4 stroke vertical shift engined mill. This for making cants. The old argument against wood loss due to kerf width does not apply to producing cants as the dimension of the cant is the same. A sharp chain saw likes bark and all the irregularity of rough logs much better than than a band saw. This approach let's the band saw do what it does best. Make boards from cants.

Try a wider blade with more tension

Maybe tighten the blade more that might make the blade cut stright,

The hook angle of the teeth is a key factor. 10' degree (softwood), 7'- 4' degree ( hardwood)

Screw the naysayers, just learn & move on. Naysayers are born professionals, after all. You don't do this for a living and I didn't see a whole lot of dangerous recklessness. It's a HOBBY, people.

Timberwolf blades! You’ll like them. Talk to the folks.

A dull blade will cause that as will. Red oak is hard to cut and the speed is another thing. If you can keep it more even.

I use soapy water on my mill because I cut alot of ponderosa pine if I don't I get the same pitch and dust buildup that you got and it screws up my cuts. Luca

Use pinesol and water about a half bottle and the rest water and that will help greatly on the build up on your blade that and more tension with your rollers close to your cant

The blade was deflecting due to time / space factor multiplied by the gravitational negative ion abyss. If you move your saw set up 2.7778 meters to the southwest you will not have any more problems. But remember that will change as Jupiter moves towards Neptune. Also noted is Uranus is getting very gassy lately.

I could not build a working mill from scrap. You are awesome. But I'll stick with the lt 35

Dennis, is there a way to make your blade guides width adjustable? Also I’m thinking more tension on the blade. One more thing make the free wheel adjustable to set tracking. I’m thinking these changes would make your saw mill much more pleasurable to use.

This is a good point about the free wheel. In one of the Cooks videos about blade tracking he mentions that it is ideal to have a tracking adjustment on both wheels, which kind of surprised me, but then when you do the math on the amount of tension a 1 1/4'' 0.044'' blade is under you can see that if the second wheel is not adjustable, it had better be very accurate and *very* rigid. So if more tension is not possible due to tracking problems, this may be necessary.

There are few problems, I think, only from video, what I saw. 1. not enough blade tension 2. buildup on sawblade - if water with dishsoup doesnt work, try water with turpentine 3. try to lower the blade guide rollers, like push the blade little bit down 4. dull blade - just one small rock, or soil in bark can do that 5. dont push hard to cut, let it go how it wants

Wood have worked well:)

time to upgrade :)

To help with blade tension try a slightly shorter blade.

yet another comment. I found that the moving carriage on mine is a little too wide. Even if i tighten the bolts down so the carriage can just move it still skews a bit when I tension the blade and the wheel tilts a little. On mine I can make up for this by readjusting the blade skew. I should not have built my carriage with so much play. only a few hunredths of an inch would have been better. I am going to look into this when I get time.

I believe you need to move your guides closer and maybe more tension?

I am about to make a sawmill and I have studied professional one. I give you my opinion: 1- The blade must be 1-1/4" wide and have a tooth every 7/8" and have a thickness of 0.042 ". The wider the blade, the more it goes online 2. Each blade guide must hold the blade between two pieces of ceramic or metal, this will hold the blade straight and push the dust from the blade while cutting. A single bearing on the top of the blade does not clean the blade and allows the blade to move down and cut in a curve. 3- On the other hand, with a wider and thicker blade, wider wheels (minimum 19 "diameter) should be used. I hope my comment will help you in your project. Ave a good one !

It's a sugar maple that you tap to make syrup much like pine tar

Speed up your blade I had a timbermate that did the same thing. Running the blade faster and slowing the feed should help. A wider blade also helps.

I think a fair market price for the mill would be 4K to 6K

The blade has to be sharpe and riding correctly on the wheels. If the wheel angle cannot be adjusted then you will never be able get straight cuts. Also you only need a little bit of lubricant ( water) too much makes the sawdust stock in the cut. The blade needs to be supported and as close to the guide needs to be as close to the log as possible. That will lessen the deflection ( diving and climbing) of the blade

So I'm just a guy on the internet here but I think the issue is with the blade guides. I don't know exactly why, but I've watched all of the budget saw mill builds on YT many times and almost all of them have an offhand remark buried somewhere about having had problem after problem with homemade blade guides, to the point that in my own build I bought the bullet and have allocated funds to get the Cooks giudes (doubling my budget in one fell swoop). Insufficient tension could definitely also be an issue, but I suspect that you're going to keep having these issues until you have a beefy, flanged, roller-style guide on there. My understanding is that the 12'' wheel is going to be an issue in the long run because it shorten's blade life, but I would *think* that you could still get straight cuts with it. Keep it up though and keep us posted!

With new sharp saw blade, Use Torque wrench to tighten blade to 24ft lbs then adjust your cutting speed, don't cut too fast, or too slow, find a happy medium 😀

Just watched this video and...you have way under-tensioned (is that a word?) Your blade. A small downward deflection at your guide would also help. You cut oak with a less-than-perfect blade arrangement, and that means that only about 10% of your result can be blamed on the sawmill as a whole...it's an excellent mill for its size. Beef up the frame, adjust the tension in the drive belt and the saw blade, put a new blade on it, and double-dog-dare another oak to come down! Good video!!!

i would think that blade tension might have some thing to do with the way its cutting

adjust your blade tension to approx. 25 ft. lbs. make sure you have a Sharpe blade and adjust your rollers so that they are with in an 1" of the log edges. you might have to slow down your travel speed some. good luck!

Yeah I think a bandsaw making one lot more difficult than one thinks. I would most likely go with a chainsaw even though that said that they don't like to go straight in. That freehand chainsaw cutting the boards they want you to rock the chainsaw and use the tip inside the groove that you have made. But I would probably try it slower. And use a electric chainsaw. With a very slow creeping Drive ideally I want to somehow keep this available to be soldered powered. Set it and forget it as you do other tasks around the homestead is the norm for this machine with safety concerns evaluated and addressed.

The blade rollers need to be adjustable,,, so they can be moved closed to the log

That is the thinnest blade I have ever seen on a mill

SEE :SAWING WITH SANDY MAY 16 2016 on You Tube.

Blade too narrow? Blade tension? Blade guides too wide?

I think your blade wandering is from inadequate support. The guides you have are too far apart and should have adjustable positions according to the width needed for each cut. You also may need guides to hold the blade in position horizontally along the length of the cut.

Dennis please take a chainsaw course. No safety pants no face shield to speak of, just glasses will not do. Sneekers will cost you a foot, get safety boots. I know this stuff costs a lot. It will last you a lifetime if you take care of it and you will live healthy and happy because of it.

I don't get the impression she cares about the value of the wood or the exercise her husband is getting not to mention the fresh air 🤓🤣😁🇺🇸

You need adjustable guides

because the cutting of the endless ribbon short curved, what is this failure?

Drive belt tension, not blade tension. If the drive belt slips, the band slows in the cut, causing it to dive. don't go too tight, or you will bend or break the crankshaft on the engine.

@@WhatDennisDoes Absolutely drive belt tension was a big part of the problem. In the video you can see the drive belt flutter. Partly due to the motor mount flexing. Also you are running too much water which causes the sawdust to pack into the cut rather than be carried away by the gullet in the band. Running dull bands will cause them to heat up and expand, band tension decreases and they pop off. Another thing was that really was firewood and not a log you were sawing there. The directional grain changes around all of those significant knots will cause issues for any mill, they just happened to have a greater impact on your mill that day due to a combination of circumstances. It looks like you built a nice mill there, just need to dial in the little things.

@@whiteoakroadfarms Thanks Jim, that's helpful advice. I will take a closer look at the drive belt and motor. Good to hear that a log like that would be a tough one for any mill.

It doesn't look like you're running near enough blade tension you need at least 1500 PSI if you had hydraulic tensioner I run 2500 to 3000 psi but mine mill is bigger. if you can sit there and wiggle the blade like that it's not tight.

Your wavy cut could be simply that your saw carriage is too light. Not enough weight so if the blade wants to go up the carraige will just lift up a bit also.

Maybe time for a different brand of sawmill?

I promise you, use (obviously) hardwood guides on the top and bottom of the blade. I guarantee it will not 'snake' and use diesel as lubricant.

Good little sawmill, major operator errors "/

Mount a planer on that rig

Bruh, you got to shim it as it cuts

I think the saw and mill was tortured. The up and down cutting you described is called snaking. It is caused by over feeding, dull teeth. and heat. You did right by running coolant on your saw but when you try to.cut half of the cant (.tree) or even boards as thick as you were the saw will get pinched and binded by weight and compression in the wood even with coolant running on.it. Heat will cause a saw to snake and run forward or back on your wheels and can cause saw to break If you are planning to cut logs this size you should look into getting wider saw blades and try not to cut wider than 2 inch cuts. Teeth need to be sharp and changed if snaking occurs. Your saw is only going to cut worse and you risk breaking band. If you mistakenly put on band that is turned backwards it will be damaged and prob not be of use untill teeth reset or swaged and resharpened. Slow feed especislly.in knotty wood and try to keep band from binding in thick cuts. I believe your saws and mill cut well considering the size of wood your were cutting and trying to.cut boards too thick. Good luck.

You have some issue , first you need a guide closer to your log . Second you need to clean your log from any debris. Your blade must be properly stretched. You also must have the right blade speed if it go too slow and you force on it , the blade go up and down .

I use the HF bandsaw mill that doesn't have rollers nor sliding guides, and I can cut up to 24" logs into boards up to 6" thick as straight as they come. The ONLY way I can do that is to start with a sharp blade and tension the blade past where I normally start to squirm. That Ain't. A proper measurement, but if my blades wanders in the least, I check it's sharp and then tension it more. Works!
