I know it is an old video but the info was just what I was looking for. I have the same sawmill for 4 years ( also manual), but only have about 12 hours of run time on it. I am still learning. Quarter sawn wood is what I want to cut ( more stabile and nice grain pattern). Now in the process of building a stock of lumber for furniture making. Cheers from Canada.
By far the easiest explanation on quarter saw.
I’m not sure, but am I the only one who’s gets there heart racing watching trees get turned into boards!
My mind was blown at his comment on the humidity of the seasons. This guy is obviously in Oz what with the accent and the tree species. I live in the northern hemisphere in an area with a humid continental climate. We have hot, humid summers and cold, dry winters. I think it's neat how we have opposite patterns not only with seasons, but with the humidity that comes with those seasons.
I appreciate your simple explanation about quartersawing lumber. It never seemed as easy as you showed.
Didn't think about the reason to avoid the central core before. A bit different than the quarter sawn system I was taught ... But that's why I just an occasional buyer and not a maker. Many thanks;!!!
The information about stress relief was gold. I'm not a greenie, but I do appreciate minimalizing waste.
There is an art to the craft and you are performing at the highest level. Thank You for sharing your knowledge.
Cheers from Missouri. Thanks for the video. You taught this old dog a few new tricks. Your application of the electric winch on top of the loader is genious! Way better than using the hydraulic lift! Best explanation and example of stress in logs I've seen yet. Hope the wildfires missed you.
Thanks for the detailed explanation. Haven't seen a video on quarter sawing this good.
Thank you for your excellent explanation! Will try it today on my mill with larch trees. Greetings from Bavaria
Excellent knowledge sharing!
I have a new mill now. Check out: ua-cam.com/video/20LFBxq2btE/v-deo.html
Thanks Mate. Very well presented and articulated
Thanks for the great video and so well explained. I'll be taking notes on all of that with my new sawmill business that i'm just getting started.
Hey Bambra, here is another way to quartersaw if you have enough throat on your band saw.
You still can do it if you have large logs, but will have extra passes.
"Quartersawing Oak: Making Expensive Lumber Out Of Free Logs"
For sure you will have less waist 🙏
Great video, very helpful and well explained. Thank you. Watching you work on that manual saw made me appreciate the hydraulic mill by a different maker I bought last year. Also, it is tough to see growth rings an inch wide and think of a hardwood tree. We fell and process 120-year-old oaks here in central PA. The growth rings are 1/8" at most, and most are 1/32" wide, Very dense, hard wood. Anyhow, thanks again for your video
Very helpful. Thanks.
Best explanation I have seen and I have watched a lot, thanks.
thanks Alec...Rowan
loved this video, informed a lot how i think about wood movement !
Really great video. Well explained. Thanks!
came via Jake Cassar's page - good watch - thanks for the upload
Excellent video!
Excellent video, very helpful, thanks.
Interesting! I appreciate your explanation on the subject. I have some white pine to cut so have
the opportunity to try quarter sawing.
Well put. Good on ya!
First of all, it is not always good to just quarter saw everything. Typically, I just quarter saw for wood working and flooring. I flat saw for dimensional and siding. I only kiln dry for woodworking. Everything else is just air dried or sold green. Slabs are typically just air dried unless the customer requests the kiln. I have a unique way of quarter sawing. I have a turbosawmill swingblade and a band mill. The turbosawmill will double cut 16 inches. If the log is prime, I tag it for quartersawn. If there are defects, it gets flat sawn. For quarterawn I draw out the pith and saw out the outside quarters with the swingblade, then double cut the center cant I just created. At this point, I will flip the log and repeat the process. At this point, I have some dimensional boards, and 3 cants. I remove the pith on the band mill and let everything air dry. When I recieve an order from a wood worker, I cut to their needs on the band mill and finish in the kiln. There is less waste on the thin kerf bandmill to maximize profits. On a side note, if you plan your cuts well, there is very little waste. My scabs get milled into stickers, the piths become fence posts, who cares if a fence stay twists. Dont be in a hurry to just firewood everything. You would be surprised what you can sell if you get creative. The only time I declare something is firewood is if the ring shake is bad or its punky. There is a really good video on youtube demonstrating the process I use.
thanks, all good advice
please post the "There is a really good video on youtube demonstrating the process I use" or post a video that you make. I too run a bandsaw mill, a WM 35HD, sourced by our own old forest, and 95% of what we produce are RR ties and pallet grade cants and lumber. I am always looking for better ways to do it
@@pamtnman1515 I cant get the link to copy here. The name of the youtube video is quartersawing with our hybrid technique by onesky puppy. I works really well
@@mandmmilling3716 OK I will look it up, thank you
@@mandmmilling3716 OK I watched that video. I grant you that it is interesting. If it works for that guy, then fine. It would not be practical for 98% of the people who run their saws for a ft living or for production. Two manual machines instead of one that is fully hydraulic, lots of space taken up by the Lucas Mill, which is a cool piece of equipment, no doubt. I suppose if you live in an area with few or no sawmills having that guy's setup might make sense. He would be cutting custom orders at his leisure. For most of us sawing average logs, our time is way way too precious to spend all that effort cutting and handling material. On quartersawing oaks, just taking out the 2-3 center inches will give 2-3 quartersawn boards. Even on a 14" log. Quickly flip the boards, edge out the heartwood and you are done and have 4-6 decent quartersawn boards. Flat saw the rest and move on to the next log.
Thank you for making this no bullshit video.
There are so many things that I liked about it.
A few of the things that I appreciated was that you stuck to the nub of the issue;
and you discussed a lot of relevant aspects that I had never knew about,
that contribute to a "better end product".
Also, you didn't try to be humorous,
we'll leave that to professional comedians; and you didn't subject us to horrid background music.
I learned a lot from watching your video.
thanks for the considered response. Rowan . See www.agroforestry.net.au for more
Very well explained,
Good Vid, Well explained.
Very nice video Thankyou.
good video
I would like to see a video on loading log and turning using your winch good video on quarter sawing
Do these saw blades spin to opposite way in Australia than they do in the Northern Hemisphere?
I don't think it's like water down a plug hole. This mill was from Canada!
Looks like you need big logs to go that route.
Neat! :-)
You could do two cants simultaneously if they were same size...?
How long do you think it took total to cut this log?
about 2 hours, alone on a manual sawmill
Nope. That method is just creating more waste. WASTE= the total amount of material that isn't going to get used. That includes the amount of material the carpenter (cabinet makers, furniture makers and luthiers included) ends up throwing away, not just the pile of waste left at the sawmill. If the sawmill cuts crap, there's a lot of waste when the product gets used. Quarter sawing should reduce waste. It also flushes out the imperfections in the wood. Quarter sawing should yield material that is pie shaped, narrow slices of pie usually, 2 inches at the wide side tapering down to a half inch or less at the narrow side. Ideally, each pie shape should be just shy of the radius of the log. A carpenter (cabinet makers, furniture makers and luthiers included) can deal with that. They'll trim, plane and edge to their specific need. Quarter sawn wood is NOT used in conventional house framing.
Thanks for that. Good points but: 1. how do I dry pie-shaped boards in the kiln? 2. recovery can be able the value of the product not just the volume. 3. We are selling/using this timber for furniture (not framing). 4. the inner cor of eucalypts contains the juvenile wood and knots form our artificial pruning so it is waste = firewood anyway.

180 degree swing blade technology will allow portable sawmill owners to get the extra dollar they need for high-quality quartersawn wood used in specialty industries. Here's a video from a Canadian firm, D&L Technologies, in which the 180 degree swing can be seen, though it is not demonstrated. This 180 degree swing blade technology opens up a whole new world of opportunity. ua-cam.com/video/BkXMLWO2IIQ/v-deo.html Contact: Owner, Mr. Lindsay Flett.
Drying pie shaped boards is easily figured out, resawing and planing, if stacking pie shaped wood presents a problem, which it shouldn't.
I'm not selling this particular saw. I have however spent the last two weeks researching a new saw to purchase. And there's no way I want a bandsaw mill. The cost of dealing with the bandsaw saw blades and all their faults, breaking, running off their wheels, swooping and diving, and, sharpening, turned me toward a swing blade saw. In Australia you have Turbosaw offering similar products.
Good conversations here.
Don Robertson do you have any idea what you are talking about? I run a sawmill full time, cutting 99% mixed oak here in central PA. I have a stack of quartersawn boards that are up to 20 inches wide. Most of the quartersawn comes out 4-6 inches wide. These are all squared boards. Quartersawing by definition results in a lot of wasted material. Has trade-offs. It is a highly inefficient use of the material, but the material that results from it is the highest possible quality. No pie shaped anything, the boards are all squared up and true lumber boards. And contrary to what you state, plenty of people use pallet-grade quartersawn oak for all kinds of rough uses around here - white oak fencing and posts, for one. If the wood is full of knots and stain, then it gets the lowest use. But whenever you cut through the center of a log, you are automatically getting quartersawn boards, so it gets mixed in the order.
@@nodnostrebor4300 waste? the method he is useing is the same way i do it, been doing it for ten years. there isnt very much waste at all.
Watched the video, no mention of quarter sawing (lap siding is a whole 'nother thing).
