" We're just outside of the town of Shelton Washington State about fifty miles across Puget Sound from Seattle and assist the Simpson plywood plant down below we're going to be touring the plant in a minute with Jim Lang and bird -- the production manager this is where they make -- MDO medium density overlay plywood that we've just been using in the porch ceiling. Let's go."
" we're out here in the yard and most of the lumber that I think -- being used with plywood is Douglas -- is that true. That's basically true at this particular plant we ran around 65% Douglas -- The remaining is hemlock and white first why is it because that's what most common on most available. -- large part of it but it's also because of the strength characteristics. And also the grade requirements that we used in our high end products are the plant OK so here always. That is all this lumber arriving either by truck or by railroad or by water right that's true holy Moly look at that thing -- call that machine. That's a Wagner -- better known as a large log loader it picks up re -- are. Log truck load of logs at a time -- time at all once aren't so where's he gonna we're gonna dump them now. What is going to do he's going to put him up here in the and beat George barker this is were removed apart from the law. We can't have a sixty inch ring let me -- six the examiner and all the way to a six inch -- he ever again had done this really gets that big pipe diameter no longer know our our average -- is around ten inches. An occasion we'll get when it's thirty inch diameter. Second growth right. Look at that -- just get up there and dropped them into place. So that the barking operation. Essentially is the first step what happens next. Once they go through and get out of -- from there it goes through our sides we have to sixteen inch diameter sides. This can cut the logs in -- they put multiple we actually got a half a foot longer and make four by eight plywood course yeah that these these. And universal dimension of filing -- And then after it's been put through the trimming what's the next step up from there we think it's the law -- and conditional lot -- Vila."
" That Jim what's the point of putting the logs into these steam vaults. Well actually go to his condition in the logs that we can feel it easier and get a much higher recovery. All right if you're gonna Vila and -- engineering operation. What actually happens in there how long do they have to be -- there -- they're practically in our rich in diameter and averaging ten hours under standard eight degree water. Clear spraying and the worst -- from about his disdain OK that softens it up Panetta goes into the I've been hearing process. Because throwaway line where we have a charger that. Puts it through computers into the cylinders quickly as possible recovery benefit. Field -- into veneers know what you're doing well -- computer does. Maximizing the yield roughly -- off that's correct I'm here and then under the veneer -- that we -- Are the big blades associated exactly at night -- and it and it secure."
