Yeah, loosing set on one side instantly screws up a band, and is not overly well known. I've done it myself and should always keep it in the back of your mind when you push a band hard and scrub it on the back shoulder, I always take the next cut slow at first to see if the proper set is till there on the roller side.

keep the vids coming, feels like a cheat code having learned the hard way.

Im a sawfiler in a large scale production hardwood sawmill. We do 60,000 board foot a day. I file/tension both resaw and double cut saws everyday. What info can you give me that i may not already know? Im 33 yo and ive been doing it for going on 6 years now. Legit just curious what a professional such as yourself can teach me that i dont already know. Absolutely love your content and your knowledge. Keep up the flawless work 💪

Hard to do that, I'm not sure how much of we know overlaps, but I will say that the times I've had companies who do production band sharpening sharpen my bands, they seem to take way too much metal off in one pass, or otherwise heat up the edges of the gullet and martensite the alloy, making increased fatigue a sure thing. They also are generally sloppier about their set, at the cost of loosing horsepower and cutting waves. I'm also a big fan of grind then set for several reasons, vs set then grind, and I can say that when I get wood from big mills, whether using a circular or bandsaw, I can not get the wood to clean up with my normal 1/16" hit or miss plane process. I do remember I got in an argument with a saw filer one day when they had mis ground some of my teeth, and the guy said "What, do you expect, every single one to be right?" and I said "As long as I'm paying, yes!". I think the biggest takeaway would be "quality control" and since you are asking it sounds like you are doing well. Thanks for commenting.

@@HobbyHardwoodAlabama The companies will take one hard pass instead of two or three light ones to save a lot of time. Also the shape of the grinding wheel will dictate where in the gullet and on the back of the tooth the wheel touches your saw. Touch up the grinding wheel to shape it the same for each saw and you will get the best results Most larger bands are benched so the back edge of the saw it longer than the front. When the log hits the band the front edge will stretch to the same length as the back and run true.

It's OK for some specialty stuff, but actually cuts slower than conventional bands per hp because the kerf is so wide. I've got some, if they were better for day to day sawing, I would be using them. They do stay sharp for a long time, but they also cost 3X as much and I can't resharpen them. Just another specialty screwdriver that has it's place but rarely gets used.

Hello Mr. Milton. First whats going on with the set gopher trap on the work bench. You explained very well the complexity involved in manufacturing saw blades.As consumers we are at the mercy of manufacturers as far as products engineered at an acceptable and affordable cost. You have demonstrated the value of the blades available . You have jumped way ahead with factors combined to make a good saw blade that cuts good. I feel a blade setting and conditioning video in the future. I guess until blades stay sharper and last longer between sharpening we will depend on you to come up with practical innovative ways to get the most out of our work and hobbies. Thank you Mr. Milton. I enjoyed your video.

Can you weld a band for a sawmill like you can for a metal-cutting bandsaw?

@andrewupson2987

22 күн бұрын

They are welded when produced. I think they laser weld, or some other uncommon (for a hobbiest) method, so probably not something a person can easily diy unless they happen to have specialty equipment. You would also need to do a post-weld annealing or the fatigue life will be very short.

@HobbyHardwoodAlabama

18 күн бұрын

Sure, they are generally contact arc welded like a metal cutting bandsaw, and the real key is getting the tooth spacing exactly correct for resharpening, getting the weld annealed properly and then grinding the weld perfectly flat. Lots of ways to do it wrong, only a few to do it right.

You crack me up, Robert! 😂 Once I found your channel, I default to your information completely. I remember one sawyer channel that used carbide-tipped bands because their long life far outweighed their cost. I'm not going to believe that until you tell us differently. Thanks for the education AND the laughs!

I have new carbide bands hanging on the wall, and if I thought they were better, I would use them. They actually cut slower per hp than conventional bands because of their wider saw kerf. They also can't be readily resharpened, and yes, nails are attracted to carbide. They do have a few specialty uses, such as skimming one edge of a live edge slab, but in reality, their cost and reduced performance does not justify their cost. For some extremely abrasive exotic woods they are also useful. In summary, I'm not overly impressed with them. They are like a specialty tool that only comes out of the toolbox every now and then, mostly never.

It depends, but generally from 600 to 1,000 bdft. If a log is muddy or overheats, the band can be dead on one cut.

Yes, they are OK, but in my opinion, the teeth have too much back angle, making the tips weak, and the beam strength is a little off, also. Decent, but not the best I've used. Good question.

@HobbyHardwoodAlabama

18 күн бұрын

That is a common problem, and due to band resonance or "band bounce" when the band is not in the cut and unloaded. For some reason, your band is bouncing very rapidly up and down when engaged at cutting speed but not in a log. If you put a camera on to in slow motion, you can see it. So when you put the band in a soft wood, especially an new sharp band, and is still bouncing up and down in the cut causing the washboard effect, until the "bounce" or resonance settles and disappears when you increase feed speed further in the cut and load up the band. Faster sawing increases load on the band and decreases washboard, up to a point. It's easy to check, when you see washboard, saw faster and see if it reduces and then feed slow and see if it reappears. You can do it one cut, and you will know what it is. Finding the reason for the band bounce is another thing, and would make a good video,.

Im still struggling with heavy head shake under certain conditions and species of wood. Big oach Logs eh ... no matter what i do, no matter which band, tension, feed rate, alignment, ... ... ..., sometimes it starts shaking like hell. I almost accepted it and tried to live with it, but the little nerd in me tells me, i won't rest until i know why this bloody saw is doing it - if i know , most likely i stop sawing. :-) Question: What are the most common reasons for head shake? I was running 7-9-9'isch-11 degree blades, i set up the mill as good and accurate as possible according to manual. And i know this is an old topic but it realy bothers me... If i know whats wrong, i could throw the saw away and buy a new one - other brand - but what if the same thing happens at the new sawmill as well because i didn't understand where it is coming from - that would be stupid - isn't it?

Head shake??

@HobbyHardwoodAlabama

17 күн бұрын

Since I don’t know the mill brand or make, it’s difficult to answer the question. However head shake is caused by uneven feeding, or uneven cutting, for whatever reason. it could be you feed motor is jerking, your feed belt is slipping, your follower bearings are skidding or grabbing under load, you main drive belt is slipping, or quite a few things, but generally is not alignment related. Blades can do it, even new ones, if they have mis set teeth or aren’t ground all the same.

I am glad to hear that! You probably are better than us guys, maybe a little less hard headed! Thanks for commenting and watching.

This is never addressed as most mills cut 90 degrees to the log length but I will site two exceptions. One is a youtuber using a chain saw to 'split' a short log. Instead of cutting across the end face of the log (which every chainsaw mill does) he cut through one bark side to the other bark side avoiding any knots along the way. This produces long strings of waste and seemed quicker while cutting across the face makes small chips and is harder on the saw and chain. This method could be applied to a long bar Alaskan style chain saw mill. Second is E Z Boardwalk saws which have angled their mills at 15 degrees to the log face. It should extend the life of the blades and reduce normal wear on the mill. While cutting, the blade pulls the saw head through the cuts due to the angle. Now, my idea is to get mill manufactures to create a new style of mill that pivots the whole band saw head perhaps up to 89 - 90 degrees. Of course this will reduce the width of cut but any angle would be better than no angle (the 90 degree cuts would only happen at the end of a skim cut so you could technically cut a longer log than your mill would normally hold by a few inches). Since the mill you use only has one side attached to the deck it would be the easiest to adapt.
