afaik, the problem with treated lumber is if you ingest the toxins present in the wood. e.g. using it in your garden, inhaling the smoke (heard it's really bad to burn that stuff) or ashes, or breathing/handling the sawdust.

did you search for "untreated lumber" in your area?

>did you search for "untreated lumber" in your area?
me again, reason i ask is because they sell untreated 4x4s at home depot around here. try searching for 4x4 douglas fir, or 4x4 deck untreated

>>455499
Glue together some 2x4's

Rough sawn pine in the 508 over here. I sell that shit

>>455536

This. The pre-2003 ones used to offgas some nasty stuff but the new ones don't. Like he said they probably sell 4x4 douglas fir at your Home Depot or Lowe's if nothing else.

If you do have to end up using PT though keep in mind that:

1) You aren't going to be able to stain or seal it until it completely dries out, which could take months, and even then it won't look the same as the rest of your pieces. Also depending upon what stain and sealant you use you might have issues with it. Painting it you'll still have to wait for it to dry but there won't be any appearance issues.

2) You'll have to use vinyl coated (deck screws) or stainless steel screws/nails AND other hardware (brackets, etc) for the ones that come into contact with the PT 4x4, or it will develop a layer of rust pretty quickly (even if galvanized.) It shouldn't progress further than surface rust since it won't be outside (and getting wet, causing galvanic corrosion) but it will be unsightly if stained and possibly cause paint to flake if you paint it. If the hardware will be hidden or you're going to paint it this isn't as much of a concern.

Forgot to add to 2):

If you're using hardware (many times used for beds) that is designed to allow easy no-tool breakdown and set up of the furniture, having it come into contact with the PT wood and developing surface rust can cause the hardware to freeze, making it difficult to break down.

Also keep in mind that fresh PT can cause skin irritation for some people and will definitely cause eye irritation if you touch it and get it in your eye. This usually isn't a concern once it dries out.

I live in Canada. After some searching it seems most Canadian Lowes and HDs do not carry any non treated 4x4s.

All lumber yards I've called or visited only carry 4x4s and they don't know who does.

*untreated

>>455602
that's odd.

i'd try to find a saw mill, either a small operation, or the guys who supply the lumber yards. you could cut your own with a cheap chainsaw mill if you have enough projects to make it worth your while

>>455499
No, the newer non-industrial, non-commercial lumber treating chemicals available for people without business licenses is safe enough. Any treated lumber use for non-residential use however is not regulated like the residential stuff so stear clear of that crap because you never know what is in it....the same goes for those pallets people love so much in /diy/. Pallets are not regulated and can come from different countries too where they can use all sorts of insta-cancer chems to protect the wood.

Just wear a dust mask when you saw or sand treated lumber.

>>455629
not OP, but i'd like to see sources for your assertions. home depot et.al. sell the exact same stuff to contractors as they do to private buyers

>>455637
Home depot doesn't sell the bad stuff. They are a residential dealer. Only certain lumber mills sell the bad stuff and it is only for commercial and industrial uses that don't involve the general public.

What do you do, show them your Illuminati membership card and they show to your the lumber racks in the back behind the beaded curtain?

>>455651
No, they just ask you for your tax ID and they look it up from there on their PC or handheld device.

>>455640
This is both right and wrong.

Lowes nor Home Depot no longer sell the CCA PT lumber which had Arsenic in it, they now both sell either ACQ or some Micronized Copper version. These newer treated ones no longer contain Arsenic which could be dangerous when burned/inhaled/ingested but still have insecticides/poison on them.

>>455565
you know nothing about wood working 2x4's are actually 1.5"x3"

get shit on noob

>>455765
lol

2x4s are 1.5" x 3.5"

>>455760
>>455662
>>455651

No, there is CCA which was replaced by ACQ as well as other micronized copper based products (ACQ and these are what you'll find sold at HD or Lowes'), but there also exist other types of pressure treatments.

That poster was probably referring to Pentachlorophenol or "penta" which is widely used commercially and is some very bad stuff healthwise. It is not sold at HD or Lowe's or any other residential store no matter what membership card you show them.
