Default Some of the reasons I love plywood.

I seldom work with anything but plywood. Love the stuff. So much more versatile than solid wood.

I have a great respect for good plywood like Baltic Birch, and I use it frequently, but I don't think much of the construction grade plywood for use in anything other than for construction. I want plywood with solid veneers and no hollow spots. I also like how stable and flat the better plywood remains. It sure makes building things with it so much easier, and without the need to worry about cross grain joints and expansion / contraction due to humidity changes.

Did you know that Howard Hughes "Spruce Goose" airplane built during WWII was made mostly out of pre-formed high quality plywood, and not of spruce as it's name implies, because the Government gave him the contract to develop it but then would not give him access to the aluminum that he needed to make it? The "Spruce Goose" was designed to be able to carry two Sherman tanks or about anything of that weight. Only the one prototype was built because the war ended and the Government didn't want it any more, but Howard went on with the testing of it and he proved that it would fly anyway, although never taking it more than 20' above Long Beach Harbor.

My father was a USAF veteran in WWII as a flight engineer. He was in LA on business and had some time to kill. He went to see the Spruce Goose and was amazed at the size of it plus it did fly. How far did the Wright boys fly?
BTW, I heard that it was glued together. Any one know anything about this? Nowadays we would use duck tape.

Part of the reason I like plywood is because it has been in use for so long. Found this quote.
"Plywood has been made for thousands of years; the earliest known occurrence of plywood was in ancient Egypt around 3500 BC when wooden articles were made from sawn veneers glued together crosswise."

Some of the ways the Egyptians used their plywood, and why. Interesting.
Ancient Egypt: Wood

WWII had the famous Mosquito bomber, reportedly the fastest plan in the war, and was mostly plywood. And then there is the lesser known, Flying Coffins of WWII. https://www.asme.org/engineering-top...f-world-war-ii

There were also storm boats, and other boats, all made with plywood, including the Higgins landnig craft.. But my all tme favorite is the PT Boats, made by several companies, and all made with plywood.

Drat, left the last bracket off of part 3. This should work now.

My first self employed stint we made sales filmstrips in Artesia, set up shop in a metal shed owned by a dairy supply. In a loft area, they had many forms and templates made of plywood that were purchased from the Hughes scrap yard. Many were used to build the Goose. I used to be on display in Long Beach, CA, not too far. It was overwhelmingly huge and when you walked up to it, it seemed even more massive. The Cargo hold was really big. The wings were so thick you could walk standing up, if you were short, inside them.

The flight deck was also expansive, and it was amazing to think that thing could get off the ground--or water since it was a sea plane. I doubt you could have had it land on tires, the impact would have been tremendous. The engines were several stories off the ground and were radial. I think they used the standard double rank radial that put out 2800hp each. 8 engines x 2800 = 22,000 hp! I encountered the jigs in the late 60s, so they were about 25-30 years old by then. No delamination was noticeable then. I wonder where those jigs are now?

Hughes invented special hydraulic systems to move the control surfaces.

The more I do, the less I accomplish.

Hughes was very inventive. Did you know that he designed a bra for Jane Russell? No further comments will be made.

I visited the Goose here at the Evergreen aviation museum. Indeed impressive, particularly relative to the 747 displayed nearby.

This is a great site but I think that the difficulty with readers accessing it is going to cause you some problems. Most longtime users will probably be willing to put up with the site problems, but I think potential new customers / visitors will shy away and may never return. I hope you get it straightened out.
