Maybe 2x4s were once actually 2" x 4", don't know, best I remember is 1
5/8" x 3 5/8". They were that way for many years, then went down to 1

treated 2x4s are still 1 5/8" x 3 5/8". At least the ones I just bought
and chopped down to size yesterday are (I'm making some cabinet
plinths).

Now, 1/8" isn't all that much but it's enough to screw up my plans for
the rest of the cabinets which means I either have to revise the plans
or skinny down the PT. I'll do the latter but I sure wish they would
decide what size 2x4s should be, PT or not.

I guess I should ask a question, not just rant, so I will: Is there
some reason PT 2x4s are bigger?

For the further education of a novice, could you explain what sort of
cabinets you are making that require 2x4s and why you have chosen
pressure treated? One more thing: When you "skinny them down", won't you
be atomizing a great deal of allegedly poisonous stuff into the air?

Standard disclaimers about my overall ignorance apply.

And another: How "deep" does the pressure treating go? If you need the
critter-resistance of PT lumber, won't you be reducing it, on two sides
of each board?


There are different grades or PT lumber. Some are rated for ground
contact and some are treated all the way through. I suspect that the non
ground contact PT boards are not Pt all the way through.
