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!😊❤

[chuckeelhart]

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!

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).

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.❤

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
😁

I see our puppy ears are standing up nicely now... Purdy pup!!

I love it when Em talks tech, very Informative.
Thanks

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.

You taught me something today. You are great to watch!

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

[LewHarriman]

Great visualization demo. Very effective information design. Nice work, Em.

[AB-nuwe]

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.

[bagoquarks]

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.

The weather has improved and the mood has improved☺

[JohnDoe-jqwy]

Great choice of Powerful insight and THANK YOU PRECIOUS LADY 🎉🎉🎉😊😊😊❤

[DanPurdy]

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.

[kennethhockey]

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. 👍☺️🤘
