Wondering if anyone knows what this is. I discovered it when I pulled my last timber to cut my last rafter. A mold of some kind? The wood is Doug Fir from the west. I also included a few photos of the frame. No more joints to cut.  :'(

It looks almost the same color as the anti blue stain dip they use on the white pine I get during the warmer months.  I wonder if they dip douglas fir also, it is on the sap wood.  Will it sand off?

Thanks. It's a weird thing. It's the same color as the heartwood. Obviously it's all spotty. It won't sand off. Seems to have permeated. Luckily I was able to use it on the outside of the frame so it won't be seen. But i am just curious. I haven't seen it before.

 My bet is some kind of red mold / fungus. I would take a sample to be analyzed. Could be trouble.  You could try Clorox treatment on some of it.

My bet would be extractives from the heartwood, something trapped that tea there for awhile.

if a dash of Clorox didn't faze it, I think that would prove Don's point  depending on the color fastness of the heartwood?   The splotchiness makes me think of mold.   I looked at the photo again, and the reproduction is kind of poor so I'm not really sure what I'm seeing.  I have definitely seen mold or fungus that color.

From pg 38 here, there is a bad pic;
https://fpinnovations.ca/media/publications/Documents/wood-discoloration.pdf
QuoteA distinct blotchy red/pink stain in hemlock and Douglas-fir is caused by Cephaloascus fragrans or C. Ibidus. Sometimes it is also found on green lumber.

The section on extractives held promise as well  :D. What you have there is a stain.
Pg 31 has an interesting section on "sour felling" trees to help dry them a little, reduce bluestain and ambrosia beetles.

Thanks for the replies guys. After doing some research and contacting the supplier. It appears the man Don P has done it once again. Pretty cool. I love learning new things!

I am saving your reference links, Don.  Thanks.  Pretty soon I'll have a wood library, perhaps somewhat sad and ironic in that the shelves will be digital rather than wood.

The usual Latin style scientific names are revealing.  One seems to be penicillin related; another suggests cephalosporin, which if memory serves is a treatment for anthrax (could not immediately verify that in Wikipedia, but I didn't dig too deep).  It's amazing how many different fungi/molds have been found useful as  components of life-saving drugs.

Not as much fun when they get on our lumber.

Good thing that red stain was only on one side that could be turned away.   I didn't see any suggestion that it could be gotten rid of easily except by planing, not easy or good for big timbers or cosmetics, in my book.  At least it was noted as not structurally harmful.

In our restaurant we use a lot of what is called quaternary sanitizer, based on ammonium chloride,  which is not hugely chemically different from table salt, sodium chloride.   I tried using it on large hay bales (old baler, no bale wrap etc),  to avoid the need for the expensive agricultural chemicals.  Mixed results, and I did not continue trying since we gave up on our own haying several years ago.  Perhaps the right concentration might be helpful with wood?  In typical concentrations, quat sanitizer won't kill much (most antibiotics don't kill, they merely prevent growth so the host body's white cell army can do its thing), but it will clean up & prevent the growth of some bugs.  Very good on odors, too, and safer than bleach.  Not toxic in at all in usual concentrations.  Sam's Club sells a version made by Economic Laboratories (they used to own KitchenAid, part of Hobart) for about $5 a gallon, which makes well over 100 gallons of solution for our use.

The authors didn't mention bleach or any ordinary chemical preventative  other than soapy water  (I did see mention of  some agents that are illegal in Canada and the USA, but not in New Zealand, wow).  Leaves me wondering why.

Editing siri mistakes on a phone is killer.  I hope I caught everything stupid, and that nothing changed just as I hit send.   Too bad the new tax law doesn't mandate better voice recognition--it hits a bunch of other stuff not directly related to taxes.

Yes that is the same quat used in food service. It is the Q in the newer preservative treatment ACQ.

Its a Gehl.  ;)

Some more photos... First time using SIPS. Really enjoyed using them. They really go well with the frame. The box is taking shape! Neighbors are a little bummed they can't see the frame now.

Haha. Are the pictures upside down? They are all facing the right way on my computer. And I'm not standing on my head.

 Roof SIPs going up.

Wow, how thick are your roof SIPS?

Here's a bit of an update: SIPs on, windows in, doors in. Plumbing, electrical ready for rough inspection. I decked the second story in 1 1/2" Doug Fir T&G. I am very happy with the way it looks as a ceiling for the downstairs. I'm pouring 1.5" of lightweight concrete on the first and second floor. After its sealed this will be my finished floor.

How dry was your DF T&G?  I had an issue with some I got from out west, pre finished it, it had been out in my shed in ambient conditions for awhile.  Installed it and over the winter it shrank and I have some gaps to deal with.  I should have let it acclimate in heated conditions for a couple months first.
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

It averaged 8%, but I was only checking end grain. This particular batch had been sitting in the local lumberyard for a few months so it acclimated enough I hope. Colorado is extremely dry, and my experience is that it really doesn't take too long for lumber to acclimate, especially 6 quarter lumber. But I guess we'll see!
