Tape? tape?
Bloody backward Queenslanders! How do they keep winning the State of Origin?

Jarrahland. Apparently years ahead of Queensland, who would thought!

Willy, You don't need to have the latest technology or to be the biggest or the best, just smarter and better than your opposition.

And have ticker as big and strong as tractor engines

And be the greatest team the world has ever seen

Not sure how it works, cutting the long wedge. Does it end up with all quartersawn timber?

Well at least dia sensi knows how to set the recorder to record something at a preset time so he's way in front of me! As to the sawing machine.....the logs would need to be dead straight with the heart centered to maximise return wouldn't they? And what would you use a wedge-shaped board for, apart from something like cladding/weatherboards? I can see how it would be done, especially with something like a Lucasmill, it's just working out what to use the material for that has me scratching my head.

Well I watched it and although very interesting it didn't show how they cut the boards from the wedges. In the old days they often used the big saws to cut the logs into 4 quarter wedges and then cut those into quarter & rift sawn boards. But this new set up seemed to be cutting more wedges than the normal 4 so not sure how they get their quoted 80% return from them unless really thin boards?

I have received a reply from Radial Timbers and they advise their timber is backsawn, not quartersawn as I was hoping. You can see their range of timber cutting profiles on their website here

Does anyone else reckon the drawing in the following link of another website is incorrect?

: Farm Forest Line - Backsawn and quartersawn :.

This might be a better image.

Sorry that did not work.

I googled ' back sawn and quarter sawn timber' and nearly all the images gave a very different picture. I could not see the difference in the image shown in the last post.
Cheers, Fred

Yes. Both are back/flat sawn. Neither is quarter sawn.

Should be great for cutting fence posts, just need a jig to rotate the log and stop it each 45 degrees. An ideal addition to a Lucas mill!
But being serious now...
What do they use the wedge shaped boards for? I can imagine laminating 2 sections from opposite sides of the log into a board with resulting parallel faces and thereby improving stability but apart from that my 6 remaining brain cells have come up with no further ideas, not even silly ideas.

Thanks for the link. I can understand their Radial 45/60/Wedge/Wedge Panel are quarter sawn and stable. Their other ones are all backsawn, and I'm not sure of the advantage and so called stability apart from the initial wedge that would relieve the stresses. I have no idea how they consider their Radial 120 stable at all, what's stopping the larger panels bowing like bananas???

They say weatherboards??

Setting up a mill just for weatherboards? Weatherboards used to be a small part of a mill's output or there was a small mill that specialised in running the boards through a 4-head planer, usually just a few workers that got boards from a big mill. Fence palings were the same sort of operation. Perhaps there is a market for weatherboards again?
