Your videos keep getting better and better as you become more comfortable with the camera. We even get dancing now. Thanks for the entertainment ladies!
video angles and quality has gotten better also. I have been surprised by how consistantly good the outdoor audio is. At some point it would be nice if you did a video on your equipment and how you approach productions.
For some reason watching her always puts me in a good mood and gives me hope in the new generation.
I like how, despite your work responsibilities, youalways carry that playfulness - in your expression and your playfulness. I began watching out of udle curiousity but you guys have got me watching to see what your up to every day. You make my day!😊❤
Thank you SOOOO much for remembering my question for such a long time! And being true to your reply, that you would revisit this subject. Outstanding! What a wonderful human being.❤
👍
No matter how you cut it, I really like these videos! Woodworkers make tons of videos about measuring. They tend to be fanatics. "Measure once, cut twice" OR "Measure twice, cut twice"
My Lady EM!!
You had me doing the math!!! Grandpa most likely sets each tooth (inside and outside) to .025. Typically, I would never say the teeth are set to .050. I would say the set is .025. (It's a set of .025s) Which is actually a really good neutral set. Then depends on hook angle if it works for your logs you are cutting and other factors.
But getting back to the set. Yeah each side added together, then add blade thickness, I get your .092 or 3. But because of blade vibration and other factors, we have our kerf set to .120. Not quite an 1/8", and you will definitely have a 1/32" of movement in the blade up and down while cutting. Almost sounds like Timberwolf blades from my good friend Tom at Sulfolk! :)
What I like to NOT hear, is that he runs extremely low sets. Some around here think that going below .020 is fine for hardwoods. NOT IN MY HOUSE JETHRO!!! Gotta have room for the blade to not constantly build friction against wood by having a low low set. The blade will heat up if you are too low, and tips of teeth will heat up if you are too high for the lumber being cut. The kerf, by it's nature, is designed to remove wood that would otherwise slide against the body of blade while cutting. My lowest is 22 or 23. My highest is 28-30. I would never run a 4° or 8° at 28-30, but I would with 10°-15° for softwoods. And I'd never run 10°-15° at 22 or 23. You almost have to run double travel speed for how fast a high hook and high set cut in good softwood. lol
Rule of thumb for hook angles and sets: Hard wood=lower numbers on everything including travel speed of blade thru log, this includes us walkers! :) Softwood=higher numbers including travel speed. Keep the sets even on inside and outside as much as possible. The inside I set 1-2 thousandths higher when the blade gets older and dished (cupped) as they WILL over time. Just their nature to start cupping opposite the direction you think they would under pressure from drive wheels. The outside (bottom while cutting) turns down over time. But, even, is faster and cooler.
Lot of folks do not know how important set and hook is not only for cutting but for efficiency and quality. So thank you Ms. EM for sharing. And keep up these tutorials. We love them and need constant reminders. Our days are not complete without your knowledge and research. Cuz, like, who else is better than you really??!! Thank you
😁
👍👍👍👍👍
sawdust can be pressed into briquettes for stoves.
I remember when working for a furniture company, we bought a computer controlled circular saw and the operators complained that the machine refused to take their dimensions until I pointed out they were cutting 50mm strips with a 5mm blade, that was 40 cuts and 200mm of kerf, hence they couldn't get out the numbers they thought, they never allowed for kerf before, just cut until they ran out of wood. Great saw, cut fast and square (once we spent a day levelling and adjusting it).
I love it when Em talks tech, very Informative.
Thanks
Very nice presentation Emerald!!!
Outstanding for the whole family for all the wonderful information and hard work you put in the videos as well 179 thousand subscribers wow
Hi Emerald. Please make a video explaining how an edger works , is set up and used etc. Keep the videos coming, they are very informative and enjoyable. Take care, GW.
just type "edger" at the search symbol 🔍 and a number of videos on the edger will come up.
As a woodworker I know how much sawdust I produce even with a small shop. I used a shop vac attached to my cutting and sanding tools in the beginning but realized that it wasn't enough. I now have a dust removal system to protect my health and although I don't cut as much as you do I am amazed at how quickly the dust container fills up and requires emptying. Let not for get the amount of wood chips that "The Boss" leaves on the ground when working in the woods as well. This should be eye opining for anyone who watched this video
Wllliam Newburry got a British patent on his bandsaw in 1809. It took many yrs to improve the band weld on the steel blades, and a woman named Anne P. Crepin came to the rescue! Bandsaws were a big part of the Industrial Revolution.
As a lumberjack .... good to know our wood is well taken care of downstream... your vids hit .....❤
I see our puppy ears are standing up nicely now... Purdy pup!!
Great visualization demo. Very effective information design. Nice work, Em.
When you're milling hard wood you may want to search out a pellet producer and sell your kerf by-product to them to make pellets for stoves. Just a thought. The accuracy of the instrumentation on the LT40 and the LT70 Wide must be very good as when setting board thickness + kerf must be taken into account.
Thx for the great tutorial. While I was aware of there being loss in each cut made, I did not know the name/term for it. LCLY rocks, as per usual. 👍☺️🤘
Well, that answers the question that I was trying to figure out how to ask 🤔👍❤️
As an old ex saw filer we were always experimenting with kerf, hook angles, back angles, tangential angles and tooth bite (tooth spacing in relation to feed speed and RPM). Pretty interesting, really.
Been down that road. At the end of the day I came back to an 8-3-30. Hook angles I've tried from 28 to 32 degrees. Called it good at 29. I think any filer wildly experiments. Tried the 2" tooth then 2.125 then variable pitch. I like the VP personally. 8000 sfpm seemed good I thought.
Those sound good to me. Our mill owner was always turning up the feed speed on our edgers and cutting the kerf down. He said he wasn't in the business to make saw dust. That's fine to a point. We were cutting about 200K bd.ft. per shift.@@supersawyer358
Assuming you're not sacrificing other aspects of performance, using a blade with a smaller kerf means you will use less power for the same length of cut. Accordingly, you will have less sawdust because you are removing less material. Your results may vary but it might be worth it to pay more for a thinner kerf blade if it saves you fuel.
You taught me something today. You are great to watch!
4:08, yeah we got this too, man who sharpens our knifes, sets in the radius they acquire in the cutter block into the system. and then the moulder I use will automatically account for it. But in another smaller company I used to work for, the moulder didn't have this feature, didn't have a computer at all. Good to know both ways, I suppose, I never know where I might end up in another time.
Thanks for sharing another awesome video ❤
You're such a sweet teacher 💕
That comparison between bandsaw milling and circ saw milling using the sawdust 'recovery bucket' is a good one. Really does show you how much sawdust is produced by the thinner bandsaw blade making it easier to imagine how much more waste saw dust thicker kerf circ saw blades produce.
The weather has improved and the mood has improved☺
Lumber yard I worked at had a huge vacuum system. The sawdust was captured in what looked like a small silo. They sold it to a company that would empty the silo a couple times a week.
I missed y'alls dance routines they add a sparkle to your video. Still a great video ❤❤❤....
Very good presentation.
another fine production ladies, really like the tour, and Em, Little buddy, + 1000 points for not spilling coffee. 😁
Thanks, good description. The comparison between band & circular is well taken. Last time I had logs milled on an (admittedly old) circular saw mill the kerf was 1/2 inch.
Lol,
You're so funny 🤣dark humor is the best! You got a mic, awesome! It's great to see the sun shining there. The sun behind you is always breathtaking. 🌹
Where's our end of the week dance routine?😁
You have a very handsome doggo assistant. Very educational wrt kerf.
Yep for one 1-5/8 board plus 5/16 teeth. I take 1.9375" for one pass.
.
Remember scribner scale has 1/4" for teeth, built in to its formula. Or at least that's what I've been told on many occasions.
.
And yes I have a pile of sawdust that can be seen from Google maps.....
The video on this one is spectacular. Some of the best so far. Congratulations.
Thanks Em; this was the first time that I have seen you talk about Kerf and how you mill takes care of milling with it.
I left a comment earlier that you are an incredible lady. Absolutely dropped it gorgeous but on top of that I failed to mention that you are also an incredible business lady that knows what she’s talking about when it comes to lumber and pricing in the marketplace so my heart is off to you sweet lady And I hope you get the credits within your company that you deserve
A very good show. I learned a good deal about milling. Have fun and be safe.
Great info Emerald, I was wondering how you compensated for the loss, and how the LT40 knew where the next cut should be. Have a great weekend ladies. TTFN
Great explanation of kerf
A saw blade is always crucial for a good cutting quality, depending on the blade thickness, there is of course also much more sawdust. Do you cut with different thicknesses, depending on the type of wood? Realy good and informativ video.👍🏽🥰👌🏽
Good morning, enjoy your day hope your family is doing well ❤
Great choice of topics..... Powerful insight and knowledge..... THANK YOU PRECIOUS LADY 🎉🎉🎉😊😊😊❤
I'm shocked how much sawdust is produced. Great way to demonstrate. Thanks for the videos. Keep up the good work.
Hi, been subscribed
Much respect and success.
Is it possible to turn sawdust into wood pellets?
It is possible but that kind of commercial equipment is expensive. LCLY finds ways to use sawdust without all that investment.
That was a really informative video about KERF,it’s how many ways that you can use the sawdust is the key I guess.
Now you could dry it out add some paraffin wax and a shop press and create safe fire starer cubes blocks whatever shape a sell the saw dust. Love your channel love your family and all of your hard work great channel PS my wife and son and starting to get hooked on all of the good information you pass along .
Great video as usual! I watch as many as time allows, but haven’t ran across one about cutting logs to grade. Maybe I just missed it…? Anyway, if you haven’t already done so, how about a tutorial on cutting logs to grade. I recently purchased a Lucas swing mill and had an old timer sawyer instructing me on how to get maximum value cutting boards. It was very enlightening and I thought it would make a good educational video.
I don't remember anything on "cutting logs to grade" and the LCLY video search does not find a video on it. Good Idea! I don't think LCLY cuts the logs like that however, so that is likely why Emerald never talked about it.
Great video. As always, educational and entertaining!
Sawdust is great for horse stalls, i know i shovelled more than i wanted to.
Hello Emerald, .093 or 93 thousands of a inch is a good setting for said blade. No need to worry over a few thousands. Nice Job. Oh no, your container done overflowed there Emerald! As always, great video. Hi Jade. You all have a fine evening and weekend.
Nice job Emerald your a pro now on the tube as usual entertaining video❤
The goats and chickens will be pleased over the sawdust as bedding. Maybe not, but the smell of the wood will be pleasant.
Great job on the video ❤Have a great day everyone 📹👌👍😉From 🇨🇦
Thanks beautiful ladies.
When you said the bandsaw kerf was 12% loss compared to a circular saw blade at 21%. How were those percentages calculated?
That will depend upon the width of the boards. The kerf on a circular saw is far wider than on their band saw.
When running a circle saw it figure 10% to 15 % by wieght is loss to kerf in a log. So a thin kerf band should be more then half in savings. 45% to 50% by wieght is lost in milling a log . That includes bark , slab, sawdust. More lumber is lost due to heavy slabbing by a sawer then any other mistake.
That was interesting and informative
I'm sure you could build a machine to compress the damp sawdust into blocks and then use them for heating or sell them
They already sell the sawdust.... any worthwhile machine for making pellets or other things like that is going to cost more than they should invest in that.
Thanks for sharing 🍸.
Some furniture is made from sawdust today. (Hi From Belarus. Harry Davidson).
Oh that puppy’s growing ❤
Interesting. Never thought about losses due to saw blade.
Emerald, I know kerf as to the blades for my miter saw and table saw. With these tools the thicker the better- I miss the old 1/8 inch blades. They last longer and "plane" the cut better because of the mass of the blade. The thinner kerf blades drift because of a lack of mass and thus incurring uneven wear. Go Gramps for his sharpening skills!
Oh and it would seem, with that band saw, the blade could eventually stretch. Is there an ability to tighten it?
@@gtmark1239 Yes there is the ability to tighten the blade. The tension gauge is on the control box side by the right hand blade wheel. The handle is just under the gauge. You can see it at 2:59 in this video, but maybe only if you know what it is because it is well out of focus.
That was a surprise didn’t realize it would make that much sawdust
Right from the start of this video, given the subject, I wondered if you would include a dance segment.
Emerald I do recommend that you put seafoam, or some kind of fuel additive into the tank of your equipment on each of your pieces of equipment my favorite want to see it’s cheap insurance. Keep your engines clean.
They don't need "Seafoam" in any of their engines! They do need "Howes Diesel Treat" in the diesel fuel tanks to keep the fuel from gelliing and a small amount all year round to keep the water out of the fuel.
@@scottsoper I was talking about the small gas engines on there sawmill and their planer that they have those are small gas engines. That’s what I was talking about.
@@bradolsen8629 I know you were talking about the small gas engines. We use a Seafoam fuel stabilizer in our generator. They run their gas engines all the time, so it is my opinion that they don't need anything added to the fuel. Diesels are different.
Very Cool..... great information....
Hello from Joe The Grower in NY
Have you ever thought about compacting that sawdust into firewood ??
They have and are considering the options. They do compost.
Commercial machines to make pellets and other like things cost a lots of $$$. They have other ways to deal with the saw dust like the compost in one of the recent shorts.
Good work and looking lovely girl 💜
To information and very important. You are so smart
Great video!
Love your puppy!
Thanks for the lesson teach, your videos are maturing as time goes on. Something for you to consider would be to process that sawdust and make pellets for outdoor smokers.
Commercial pellet machines cost a lot of $$$. LCLY finds ways to deal with sawdust without all that capital expanse.
Thank you , that makes sense.
Interesting!
You may need a hank "kerf:chief when dealing with sawdust.
Great video, as usual!
It's still working with your ashes and woods from sawmill machine
Love your videos. What do you do with all the saw dust? Do you package it and sell it or dispose of it in other ways?
Always wondered about that when watching your videos?
❤️❤️❤️😍Emerald😍❤️❤️❤️
From a normal tree, how many % will be usable planks? And how many minutes will it take to get it from stock to stacks?
Hey Emerald, how do you know how fast to feed the saw head into the cut. Thanks.
You need to add a conveyor belt or or buckets.... For your kerf
Wood-Mizer has a conveyor belt system for the sawdust. I don't feel they really need that now; however when they get the LT-70 WIDE someday, I would re-work how the whole lumber yard works and add the conveyor belt system as well.
That is where partical board came from.
Pretty green eyes 😊
Good info.
Do y'all have a compacter or briquetter to turn this sawdust into burnable pucks or logs? It's a huge deal in Europe, and many heat their home with a dedicated heater for burning these pellets. Interesting subject, and a great presentation!
LCLY deals with their sawdust by selling it for bedding and other uses. Some of the sawdust comes back with manure in it and is turned into compost. No need to buy expensive briquet machines.
And the Oscar for best supporting actor goes to... drum roll please...Sounds of envelope opening...KT40 Wood Mizer. Thank you. Thank you very much
I love your videos. How do you determine how the depth of your first cut on each side that you cut off each log?
Emerald's experience. She eyes the first cut. The cut on the opposite side is likely aided by the computer.
What the saw dust used for ??? gardens maybe
Animal bedding is one. Often the animal bedding comes back to them with manure in it and is turned into compost/soil.
Very informative.
WOW! That's a lot of saw dust!!!
... nighty two thou ..!.. a credit card is 0.030" and a matchbook is 0.015" thick for in the field ..!
20 lb paper is about 0.0035, 24 lb, 0.0040, 60 lb (card stock) is 0,007.
The color in your hair is fantastic;
quick question, how do you wear your hear while working and not on camera?
They are just as you see.
No computers on my wood mixer plan on 1/8 inch for the blade.
Outrun guess work logs in,logs out.
