I was a hot press operator at a plywood mill back in the 1980s. Much more hand work then. The glue was applied by a four person crew, one person feeding 4' core pieces through the glue spreader, one person catching them and laying them out and two flipping backs, centers and faces onto the glued core pieces. Our mill did 24 panel loads. The stack of panels came to me via conveyor which fed into an hydraulic pre-press that compressed the sheets just enough so I could handle them. Then the panels went on a vertical ride with me to the top of the hot press. There I fed them one at a time between plattens. When the press was full and I was back on the ground, I'd close the press, wait 4-6 minutes and do it all over again. From the hot press the panels went on to the trim saws and sanders. Lots of hard, physical work, but very rewarding - you'd made something that would be used all over the world.

Very cool footage. A super-important step is that the individual plies are layered with the wood grain of each at 90-degree angles to the sandwiching layers. This is the entire point of making the plies in the first place. This alternating of the wood grain in each layer is what gives plywood its tensile strength.

[@johnklekotka1028]

Yes, good point. I don’t remember them showing how that step gets accomplished.

I get your point, but if the sheets are cut into 4 X 8 the same way you could not do that. Half the sheets would need to be cut the other way.

They forgot to include the last step after packaging, the warping process! The warping process occurs in transit, from when they left production until their stocked for resale. The wood was flat when it left production but because of the strap on each end of a 4x8, the sheets become warped/bowed in the middle. New plywood, pre-warped for your enjoyment.

[@glenerickson358]

What about the bowed and twisted 2x4s they want full price for? 🤦‍♂️

[@spencerferrier3857]

That's not how it warps. At all. If the ambient heat & humidity are at a certain point in relation to the moisture content of the veneer, or if some of the veneer had too much moisture, the panels will warp as they cool coming out from the press. Usually happens due to moisture, but can easily happen if the hot plywood cools off too quickly.

I make the glue used in this plywood manufacturing process. Extremely expensive raw materials involved in the resin manufacturing side of it. Was really cool to see how it was applied and pressed.

[@causewaykayak]

I wish we could buy such good glues for small job fabrication. I used to live near Southampton England where Borden Chemicals made marvellous adhesives for aero and boatbuilding. One day in the 70s some air pressure fault blew the fine powder resin out if a large silo and across town WHOOPS. a lot of resprays and replacement windows needed after that mishap. Now whatevet happened to Borden and Casco Cascamite glues I don't know but the modern retail offering is worthless. I think it was either a water activated casein glue or a phenolic resin . Whichever, a boat made with it stayed together and Cascamite was our only glue legal for aircraft construction . I see on U Tube the lady who makes Culver Props (worth watching her at work on UT) had problems sourcing adhesives . Famous as she is someone got her a substitute in the US .

[@Finnimagoo]

@Rathlin Postman @Rathlin Postman Yes, the problem with smaller business customers here in New Zealand is that they can't purchase enough glue to make it worthwhile for glue manufacturers, forcing them to buy overpriced low quality glue retail. Our Phenol-Formaldehyde based resins, which are used in marine ply, for example, are made in 18-ton batches, so it wouldn't be worth scheduling reactor time for smaller jobs. Most resisns we make also have a short shelf life, making it difficult for smaller businesses to buy in bulk. The short shelf life is good for us as it protects us from large chemical plants in China or India for example, where they could make it for a lot less. Their Resin would be near expiry by the time it arrived in the country.

[@causewaykayak]

@@Finnimagoo ohh it's near bed time here but I really wanted to show appreciation of your quick response. It seems that you are speaking as an adhesive manufacturer ( true or false?). I find it a pity that the prospects of getting hold of decent materials is a serious limitation on proof of concept designers and prototyping workshops. I suppose these problems are nothing new in the Anna ls of engineering development. It just so VERY frustrating. Lately, and with working in wood, I have used epoxy resins (generally contraindicated for my tasks) to get projects advanced and explain the adhesive dilemma to interested parties. Dry powdered resins were always a mainstay. I wondered if Chinese manufactures would be interested in producing small containers for retail. Generally I find Chinese suppliers most helpful with responsive technical desks and reasonable delivery times. Moreover where kit has arrived damaged, restitution is a phone call away. Some of our UK sources could take a lesson in customer service.

@Peter Evans The implication is that the end-purchaser is getting ripped off. Let’s be fair here. The cost of goods sold (wood + manufacturing costs) is only part of the equation. The manufacturer has storage costs (building, staff, sales, etc.). They sell to at least one other level of distribution for a smaller price than you’ve quoted. The channel participant has their storage, transportation, employee and other costs. This level of channel participant sells at a wholesale price to a retailer. The retailer charges the exorbitant price to the end-purchaser and hopefully makes a profit after their brick-and-mortar costs, employees, advertising, etc. You also haven’t mentioned that there is more than one plywood manufacturing company in the world. If Plywood Company A sells their product at too high of a price, either because they are terrible people or because they are covering inefficient manufacturing costs, then Plywood Company B will do its best to sell products of similar or better quality at lower prices. I think the retail price is more reasonable than you imply.

I was to understand to make plywood the strongest it was supposed to be layered cross grained. At what point of the manufacture was the ribbons rotated for this cross graining? It was Henry Ford that pioneered the assembly line. "Bring the work to the people, not the people to the work." Amazing engineering feat from the drafting table to the finished product, and also for the flow chart of the work.

[@ethanlamoureux5306]

I used to work in a plywood factory. Ours was a much smaller operation, and we didn’t process the logs into veneer, instead we got the veneer by truck from a separate plant. So our process started with the stacks of wet veneer being fed into the dryer. When they came out they went thru the moisture detector, and anything too wet got a red paint stripe and had to go thru the dryer again. They then went down a conveyor where they were inspected (my job) and put into different stacks depending on grade. From there all the pieces less than 4 feet wide (random widths but still 8 feet long) would be cut in half into 4 foot lengths for making core, which runs crossways to the 4x8 stack. The core veneer then went to the glue spreader, which had rubber rollers coated with glue that would coat both sides of the core veneer. The veneer was manually fed into the spreader and manually caught on the other side and manually laid up in a stack between 4x8 full sheets, as many layers as necessary to get the necessary thickness. The guys doing the layup process were amazingly fast and got paid bonuses for production. After layup, the stacks of assembled veneer went to the hot press where they were inserted into slots by 2 guys on an elevator platform with pusher sticks. Once all slots were full, the press was started. It would clamp down at full pressure and hold it for so many minutes before releasing, then the press operators would push the plywood out the back of the press and load the next batch. The stack of plywood then was taken to the cooling area where it was left for hours to cool down. After cooling, it went to the saw line where each board was planed to the correct thickness and trimmed to exact dimensions. Finally it got a stamp showing where it came from and what shift made it and then stacked, banded and stored in the warehouse ready for shipping. This was not finish grade plywood so it didn’t have to have knots patched or anything like that.

[@spencerferrier3857]

I work at a plywood mill currently. Our system is similar to your experience, except for a few things. We do peel our own veneer on site, and clip strip core out of the ribbons as well as sheets. Our glue set-up is different, using cascading glue heads. We only have 1 press operator per shift. Lucky me (swing Press Op). And we trim the pressed panels hot, straight out of the presses. Go through the saw line to be sorted into CDX, TruPly, dunnage, Shop, etc., then to the strapper, stenciler, and doubler.

The saw line only ran during the day shift, so the afternoon and night shift production got stacked up until the next day.
