I look at the project and gage my choice on the quality and strength needed and the price. I typically prefer plywood mainly because it has strength from long continuous plies of wood. I use it for large panels for cabinets , roofing, drawer bottoms etc. I used treated plywod for the floor in my outdoor wood room where it gets wet and for the sides of my outdoor shed where I keep the firepit supplies. I would not trust OSB for either of those applications.
I used OSB on the walls and ceiling of my barn just for a surface that I can drive screws into and that will hold up the insulation and it was cheaper than plywood and I did not need the finished look of drywall. Try breaking a 4” wide piece of 3/4 plywood and a piece of 3/4” OSB and see the difference in strength.

Just as Jim said. I prefer PLY over OSB always except for the cost so I will use it at times.

In general, I don’t like to work with ply, OSB (or MDF). However, when I need to use one of these I use the following guidelines – -

If being super flat and secure is important, I use MDF.

If it is going to be visible, I use ply (often hardwood veneered ply).

If it is going to be hidden from sight, I use OSB – cause it’s cheaper.

All ply all the time.

I did once see a floor in a home that was sheets of osb sanded and finished, it was very stunning, but only because it was a juxtaposed use of the material.

I agree with Rich on 2 & 3. When you say “When either/or CAN be used” Little Word that usually means “Building Code” which is MINIMUM!.....

Sub Floors in New Construction… a Spec Builder will obviously use OSB … CHEAPER!! Ever see what it looks like after it’s been rained on? Watch the “Little Pieces” jump up when you TRY and screw it down? The Edges fall apart when you missed with your Hammer? OSB T&G Swell up for no apparent reason? Have to sand the entire Sub Floor before applying anything over it?

ALL the above means 5/8”, Fir, G1S, T&G, Screwed and Glued with PL Premium if you want to build a Home that you’d be Proud to attach your Company Name to. I did for 30 Years! Building Code says I can get away with OSB and a lot of other “Less Substantial Materials”, and it’s Always Bare Minimum. Certainly “Codes” vary by Countries, States, Provinces, How many Inspectors they employ that ACTUALLY go out and look etc.etc.

Roof Sheathing: 1/2” Ply Sheathing Grade. Trusses 16” O.C. Code says …. 1/2” OSB Trusses 24” O.C. is okay. My Foot went right through a wet piece when I was helping a Crew RIP OFF all the SAGGING Shingles and OSB on a 5 year old Roof! We (My Crew) put on 1/2” Ply…AFTER we put Blocking between ALL the Trusses where the tops and bottoms edges of the Ply, would meet. Plus $80/$100 Bucks worth of PL Premium and 25 Year Rated 250Lbs/Square, NEW Shingles.

Exterior Walls: 1/2” OSB is Acceptable. Cover it Quick before somebody sees it.

AND: As Jim said (only differently) Lay a 4’x8’ piece of 3/4” of each across 2 Sawhorses with 5’ open between them, then JUMP up on each. HINT: Ply First, OSB Next. Shortly thereafter ….make sure you have the name of a Good Chiropractor …. HA GOTCHA!!!

How come you don’t have your Nosed buried in some Skeletal Model instead of Goofin’ around on LJ’s?? ...LOL…

Furniture? OSB? Never heard of it!! MDF is okay. Particleboard (If they still make it, use to be called K3) Plywood? Sure if it’s an Exotic Veneer, or Ply that’s going to have a Laminate/Veneer applied over. DO NOT Try that with OSB!!

Just out of Curiosity where did the Knowledge you’ve obtained come from? (NO! I’m NOT trying to be a Smart Ass.) You said to ask. Right? Your an OSB kind of guy??? What? Little Pieces of Leftovers all glued together?

I was going to ask something else about Solid Strong Ply, but there’s a Lady in your Picture so I better not. Well ….NAHHHHH!! RICK! STFU and close this off!! OKAY! OKAY! I have to get back to the new “Box” I’ve been Designing for an End Table anyway.

For woodworking I have yet to use OSB. I do work in the construction industry so I do use OSB quite a bit, but it’s no good for woodworking in my opinion.

Plywood is great for a novice woodworker like myself. I use it on nearly every one of my projects. I generally use cabinet grade plywood for most of my projects and alot of my shop furniture and the like. I will use general project plywood for sawhorses, occasionally a jig, and on a few projects.

OSB doesn’t have alot of uses, but works fine when it is acceptable.

hey Rick – I have not started Palmer yet!! I start in about 3 weeks!! So I can fool around on LJ’s for just a little longer….and then after that I’m sure i’ll be very SICK of the spine and everything else that has to do with the body :) :)

I actually have worked in a lumber yard for 8 years. In sales, and actually out handling the stuff. So i’ve learned quite a bit.
