Typo on real board dimensions Answered

On the page https://www.instructables.com/id/SKDD65KF82EXL5C/ it states:

  • Did you know that 1X10 lumber's actual dimension is 3/4"X 9 3/4"?

A 1x10 is actually 3/4" by 9 1/4" not 9 3/4"

You lose 1/4" in the saw cut? Or by your dimension it's 1/4" on one cut and 3/4" on the other - can you explain how this works? L

You lose the dimensions when they cut and dry the board - When the lumberyards get the wood, they actually cut it to the dimensions you are buying - for example a 1x12 is really ripped to 1 inch by 12 inches, but during the drying process on their site, the wood loses so much moisture and such that is condenses itself down to 3/4 inch by 11 1/4 inch.

OK, that makes sense. So what you actually get depends upon the type of wood and how it's been processed too? L

In my personal experience, 99.9% of the time you can follow theguides in the attached image. There have been rare instances where I've seen a board that either was ripped poorly or dried oddly any the dimensions were off by up to 1/4 inch. I usually build stuff in Maple, because it is readily available in my area.

Interesting. However, living in the UK I'd more likely be getting Scandinavian / Russian pine, and timber merchants sell in mm x mm dimensions (no tables required).

You should really add this comment to the actual instructable, so that it is seen by people who need to (and the dimension thing could be down to different suppliers or finishers).

That was my original intention, but after going thru the sign up process etc, I got caught up in reading the forums that I opted to post it here... oops
