Mark J Posted February 26, 2020 Report Share Posted February 26, 2020 If I'm buying wood from the lumber yard what is a reasonable expectation for the actual thickness of 12/4 hardwood? I know it will be less than 3", but would you expect 2 7/8" or 2 3/4"? I've seen both. Quote Link to comment Share on other sites More sharing options...
drzaius Posted February 26, 2020 Report Share Posted February 26, 2020 Same here, but it's usually closer to 7/8. That's for rough lumber. Quote Link to comment Share on other sites More sharing options...
Martin-IT Posted February 27, 2020 Report Share Posted February 27, 2020 I have always seem at least 12/4 in the rough, never under. Quote Link to comment Share on other sites More sharing options...

duckkisser Posted February 27, 2020 Report Share Posted February 27, 2020 depends on who is doing the work, each company is different I once bought some wood that was priced for 3 but it was closer to 2.5. but it was such great wood that I could not leave it int he store. but more often then not it was at 7/8 Quote Link to comment Share on other sites More sharing options...
curlyoak Posted February 27, 2020 Report Share Posted February 27, 2020 From my sources on rough sawn hardwood lumber 4/4 is alway 1" or more. Same on other thicknesses. Usually it will dress on 4/4 25/32 to 7/8". On occasion parts of the board is under. Not enough to complain. Quote Link to comment Share on other sites More sharing options...

Mark J Posted February 27, 2020 Author Report Share Posted February 27, 2020 And I'm not complaining, just trying to figure out what to expect, so I can design and plan accordingly. Quote Link to comment Share on other sites More sharing options...
Chestnut Posted February 27, 2020 Report Share Posted February 27, 2020 The wood I get varies a lot. Some of the rough is right on. Some of it is hit/miss planed and ends up 1/8" under. I don't start to see 1/4"-1/2" under until I get into S3S but i stopped buying that because it's expensive. Quote Link to comment Share on other sites More sharing options...

I would design and plan with a confidence level... If you buy a 12/4 board there's a best guess as to what thickness you're going to get out of it... Something like this: 2.25" thick = 100% confidence 2.5" thick = 90% confidence 2.75" thick = 60% confidence 2.9" thick = 25% confidence 1 Quote Link to comment Share on other sites More sharing options...

Why not ask the source? I think there might be standards within the lumber industry. I think members adhere. For me the only time the rough wood ends up too thin is when it is crooked and takes a lot of work on the jointer and planer to flatten it. 1 Quote Link to comment Share on other sites More sharing options...
