The price of osb And boards!

[TnAndy]

Bought a Woodmizer sawmill in 1991....only lumber I've bought since then is salt treated when I need it, and furniture grade plywoods for cabinet work. My guess is that mill has paid for itself several dozen times over.

Built a 30x50 shop back in 2007-2008. $4.50-$4.75 per sheet for 7/16.

Built my current 40x72 in 2015. $7.50 ballpark.

Just checked now....$12.24/sheet at Menards.

What's odd is that oversized 4x9...is cheaper at $11.83 a sheet.

1/2" CDX 3-ply is $11.06
3/4" is $20 a sheet.

3/4" is $20 a sheet.

3/4" WHAT? CDX?

I don't buy much CDX regular but mostly PT or better.

The last bunch of pressure treated plywood I bought from Lowes should have been labeled "new light weight".

It had numerous huge unfilled voids and I think because of the huge voids with no glue it delaminated quickly.

At $30/ sheet for 3/4 it's useless.

In contrast I've several OLD large pieces of PT plywood that have sat out in the weather for years and are still solid. I also bought some marine plywood a few months after I bought the "new lightweight" for $65/sheet and it's excellent.

Yea that was cdx

Most people do not realize lumber, plywood and OSB are commodities, traded on the Futures Market like most commodities. An uptick in demand is met with an uptick in pricing, and vice-versa.

Newbury, marine grade plywood isn't treated against rot, decay or fungal growth. I would suggest covering it with paint or other methods to preserve it. It will rot just like regular plywood. It is the construction and the grade of the plies that makes it makes it marine grade.

I had bought a sheet of pressure treated plywood from Lowes to make gusset plates for some roof trusses I was making. I created a lot of sawdust sawing up those gussets. In the end, I had to throw them all out. There were so many voids in the plywood I had no faith in those gusset plates. Ended up using galvanized nailer plates instead. So in the end it cost me a lot of wasted time and money.

That was about the crappiest plywood I have seen, but since I rarely saw up a sheet that much, I have no idea if it could be typical quality. Most cases I make 1-2-3 cuts on a sheet so I do not get a chance to see all the voids like I did when cutting the gusset plates. All I can say is that it gave me another reason to understand why OSB tends to rate higher for structural use.

Maybe in the old days when plywood had continuous plys it was something to rely on. If you are using the whole sheet, perhaps voids average out and don't matter. But when you start cutting small pieces and every edge has noticeable voids, the plywood is no longer homogeneous enough to serve it's purpose. Might be better off with traditional knotty pine at that point....

I usually put 3 layers of paint on all my plywood. Even the stuff that delaminated BEFORE it delaminated.

My guess is that mill has paid for itself several dozen times over.

Did you factor in:

*The value of the standing timber
*The capital investment to harvest said timber
*Value of labor to harvest said timber
*Value of labor to mill said timber
?

Then again, maybe you've used a shipload or ten of lumber. Or you don't consider your time a tangible asset other than the enjoyment you receive from employing it.

From my readings the primary difference (other than no voids) is the waterproof glue used.

Well, I bought mine in 2012 and it provides my needs for except for pressure treated and plywood.

Did you consider that for those of us growing trees we often have "surplus" that we need to get rid of.

I haven't milled very many tons of lumber with my Woodmizer but I have a constant supply of trees I have to cut down just in the process of making and maintaining trails.

Even to just let them rot I have to put in labor to get them out of the way. The slight extra labor to drag them to my mill and process them is minor compared to my having to drive 40 miles to buy a piece of lumber.

I also mill out my own lumber with my Norwood BSM, I get what I want, when ever I want and "I" control the quality!

been doing so since 1996, I can't even guess how much money my mill has saved me, easily paid for itself many times over.

And "IF" I feel like it, I can custom mill some lumber for some one who has logs to be milled. Here's some lumber waiting to be turned into a HUGE porch, on a cabin,

to make some extra money...
