ultralight plywood?

[Colorado Hick]

Im trying to figure out how to do a really light weight titan39.

What do you all think about ultra light plywood? https://ultralightply.com/ ? Its only costs 10% more then baltic birch in my neck of the woods.

It appears to be okay. However, it is difficult to see how thick the outer veneer is. If it is only film-thick, the it would be a no-go, unless one removes that veneer where a panel is to be glue to. Perhaps you could order the $15 sample pack so that you can check to make absolutely sure that the outer veneers are the same thickness as the core veneers.

Love the idea. I used Douglas Fir for similar reasons, but ultimately wanted Poplar which was way too expensive. I've seen threads over the years where people built a T39 out of 3/8 ply with good results. Lot's of options to reduce weight. Give it a go and please keep us posted. Thanks for taking one for the team!

If you blow up the picture of the 1/2", it looks to have a thin veneer on top and bottom.....and boy, that's expensive!

Looks the same as the BB in my neighborhood with the outer layers slightly thinner than the inner, but not a paper thin cosmetic veneer. However, my eye's aren't the best.

The veneer on the 1/2 inch looks really thin compared to the 3/4.
