Talk:Quarter sawing

Copyright issue: The content of this article is lifted word for word from the external link listed below (http://www.lumberpost.com/ArticleID-94.htm), which clearly has a copyright notice at the bottom. At least the explanatory image was not also "borrowed".

Can somebody at least paraphrase the text? (oh, I hope not me have to...) And get rid of that reference to medullary flake unless it/they can be described/defined/linked so the sentence makes some sense. Cheerio, human 03:57, 21 September 2006 (UTC)[reply]

Quarter sawn lumber can be produced in several ways, without necessarily quartering the log first. The final product is what justifies the quarter sawn label. A board with the growth rings directed vertically through it while observed end wise is all that is required to meet the criteria. Mlouiskroll 14:37, 1 November 2006 (UTC)[reply]

What the..

This article fails to define quarter sawing or explain how its done and instead mearly extols the qualities of quarter sawn. Can someone please put in an actual explanation of quater sawing? Thanks. 69.232.72.76 09:16, 2 May 2007 (UTC)Sandy[reply]

Rift sawing rare?

Any time that boards are cut from a log they are cut along the length (axis) of the log. This can be done in three ways: flat- or plain-sawing (most common), quarter-sawing (less common), or rift sawing (very rare.)

The process indicated in the US as "quarter sawing" yields a few boards that are quartersawn, but mostly riftsawn boards.

Seems mutually exclusive re: rift sawing - does anybody have more definitive information (industry stats)? — Preceding unsigned comment added by 63.170.119.232 (talk) 17:50, 19 February 2013 (UTC)[reply]

The process indicated in the US as "quarter sawing" yields a few boards that are quartersawn, but mostly riftsawn boards.

To my reading, it also sounds like the definitions of "quartersawn" and "riftsawn" used in this sentence are the opposite as those in the riftsawn article. Given the comments about much confusion between the two, it seems like there may be two different interpretations being used here.

The illustrations in this article are misleading. They're not true quartersawing (which is what we need to explain the principle), they're a commercially expedient approximation of quartersawing.

As is well-known, quartersawing and riftsawing are identical for one board, running through the middle of the log. They're pretty close for a few boards either side of that. So this method is "riftsawing the centre", then turning the remainder to offer a new centre, because those boards are near enough. It doesn't help to explain this article though.

There used to be better images, but they were removed (as noted on this page) by Delta / BetaCommand / Werieth, a long-time indef-banned sockpuppet and general nuisance. Andy Dingley (talk) 16:33, 22 July 2015 (UTC)[reply]

needs a pic

I had problems imagining how flat sawn boards were cut out of the log. I would like to see another graphic like your first one, but showing flat sawn.

I can't figure out how to attach a picture here, but a single pic showing all three cuts is in the video at...

It's 33 seconds into the video. Pb8bije6a7b6a3w (talk) 14:51, 11 April 2013 (UTC)[reply]

Image

The image linked in the article is named flatsawn. At some point in the past there were images attached named quartersawn and quartersawn2. Why were they removed? The remaining image seems to be the least helpful for anyone coming to the page. I checked the images in Understanding Wood and they are much more useful. As it is the image in the article depicts a corner case example of quarter sawn lumber. Who deleted the good pix? DouglasCalvert (talk) 02:29, 21 April 2013 (UTC)[reply]

I did a little digging the article used to have the following lines at the beginning:

[[image:quartersawn.svg|thumb|250px|Schematic Quartersawn log using a common technique]]
[[image:quarter sawn2.svg|thumb|250px|Schematic Quartersawn log using a less-common technique]]

I tried adding them but the image links are broken now. These images were removed with this commit:

https://en.wikipedia.org/w/index.php?title=Quarter_sawing&diff=430551772&oldid=424119423

The commit msg is "cleanup" which does not really give much insight into the image removal. The author of that commit has a long history on wikipedia and has been permabanned from editing. Does anyone know how to retrieve the old images?

Description of rift sawing

Odsus1 (talk) 00:21, 22 October 2018 (UTC)The description of rift sawn in this article is absolutely incorrect, rift sawn is defined as sawing a log in a manner where the grain is between 30-60 degrees to the flat face of the board and is not rare at all, quarter sawn is defined as 60-90 degrees to the flat face of the board.[reply]

rift vs quarter comparison and diagram don't match

The section "Comparison to rift sawing" directly contradicts what is shown in the the AWI_Lumber_Cuts.svg diagram, cementing the confusion and ambiguity between rift and quarter sawn. I have no idea if the diagram is wrong or the paragraph is wrong, I just came here doing research on wood grain and found this serious flaw. Somebody who actually knows what these term means is going to have to disambiguate this and let me know so I can edit it or do the edit. Metaxis (talk) 15:35, 29 June 2024 (UTC)[reply]
