Gluing up treated lumber

[EddieWalker]

Indiana
I have decided to just use 6x6 treated posts side by side.
My glued up idea sounds like more work than it is worth
Thanks for your answers tho

Your strength when talking about a span is going to be in the height of the lumber. A 6x6 on the flat isn't going to be as strong as three 6x6's glued together. I wouldn't drive a tractor over 6x6 posts on their side across a 10 to 12 foot span.

Nope. It's mostly used by the Amish, to make outdoor furniture for sale, and pole barns.

Interesting...I wonder why unless it has something to do with the finish they use?...for un-painted etc. like out door furniture I can't see the logic...?
...But I did google "KDAT" and see that is promoted to the construction industry...I guess if you paint/stain/seal/calk the material while it's dry it makes a difference when it is exposed after the finish is applied...?

The lumber I am familiar with is all (what I have seen/used) clear structural grade material...I have encapsulated many a 2x10 as engine stringers etc...the KD lumber makes a world of difference...!

me thinks you meant "three 2x6's glued together"...??

Your right, that's what I meant. LOL

We used some KDAT for exterior trim on our house. The main benefit is stability. Regular treated wood wants to hockey-stick as it dries and is constrained by fasteners. KDAT is a lot more stable. My builder used it to make a pretty nice gate for his home.

I knew if I hung around here long enough I would learn something!... KDAT... cool.

Exactly. If wet pressure treated is not dried evenly, it can be a disaster.

Use KDAT, you avoid most of the surprises, and you can paint, or stain immediately.

If you have a friend in the local utilities company whether it be electrical or telephone, ask them when the next time they
change out a pole to see if you can get it from them or their yard. If not, go to your local building supply or electrical
supply store and purchase a pole and cut it to the length you need. Since most poles are made of Douglas fir and treated
with kreosote you should have this pressure treated problem solved and you won't have to laminate anything together and
save you time and Money. But if you want to spend time and don't care about money then go ahead and screw and glue
to your hearts contend. By the way I have been in the construction industry for over 35 years and I hope I don't or didn't
offend anyone. Just my opinion cause I use them when I can get them for fence posts. Best darned things in the world for
fences and I'm gonna build a bridge with them also.

One of the local lumber yards carries 6x10 and 8x12 pressure treated wood. It's used for guard rails but it's what I would make the bridge out of. Do it once and forget it.

Gramps was a lineman and then line superintendant for the telephones for 35 years. He'd buy up every pole he could get his hands on.
We used them for corral posts, shed walls, bridges, everything he could think of. Most of his farm ended up supported by utility poles by the time he retired.
Used to dig the holes with a 2 man hand auger and a spoon.
