Hi Hardwood,
The density of this Paulownia plywood is about 300KG per CBM. I think it should be lighter then the hoop ply. As we known, the Paulownia has more lignin and lack of fiber. It is why it is not so strong but light. This also makes it stable. When the moisture changed, it changes very few.
If must be consistant thickness over the entire sheet. It have been calibrating sanded two times.
Peter in QLD has uesed this products for 2 years. He can also supply this products to you. You can contact with him for more information.

Thanks and Best Regards
Danny

thanks for the reply Danny could you please advise me of peters contact details.
Cheers Hardwood.

Hi.

I think that if you could supply 4mm (3+2 layers) and 6mm (5+2 layers) paulownia ply with a harder outer vaneer, the small wooden boat builders would be very happy. We could be building very light boats indeed.

I have used paulownia timber and it is wonderfull and does not have any significant weaknesses.

Cheers.

Danny has sent me 2 small samples of 1mm 3ply.I haven't used any yet,but it looks top stuffI will let you know when I use it on a modelThanks Danny good service

Couldnt agree more.
4 or 6mm ply to marine ply standards.
Please let us know if anyone is sourcing this.

Hi all,
The thin marine grade paulownia is really good idea.
Now we are doing 3X6(915mmX1830mm) 4.5mm 3 layers full paulownia plywood for Japanese market.
But this is MR glue, and without birch veneer finishes.

If you really want this products, I shall make some sheets as samples first. For you to test.

Would like give me your emails? Then when the samples are finished, I can inform you and send to you.

Best Regards
Danny

I hope the products could meet your requirements. If you had any other requirements, please contact with me.

Best Regards
Danny

I'd like some 4 or 6 mm with or without facings to try out. Maybe we need to do a group order to get it into aus ?

I'm very interested in 6mm for the next boat project!

Danny came good and sent my brother Stu in New Zealand some samples of his paulownia marine ply. Some samples with the outer veneers of birch and some of 100% paulownia.

Stu is extremely excited about his test results of the 5.5mm 5ply 100% paulownia sample, which by all accounts will suit his needs very well. He will soon be building a Paper Tiger cat. By his calculations, the 5.5mm paulownia ply will produce a stiffer and possibily lighter hull than the currently used 3.5mm Okoume ply, which is substantially stiffened with complex and expensive carbon/foam composite framing and bracing. Looks like the paulownia ply could be set to turn construction techniques the full circle back to 100% ply! If so, terrific for the PT class.

The current construction method produces the hulls for around $12000, so Paulownia ply should be substantially less than that.

I have ordered plans for the Crowther Buccaneer 24' trimaran which is a ply boat mostly skinned in 4mm gaboon so would be VERY interested in Paulownia ply.
But I was originally trolling on here to gauge its suitability for stringers and frame edging. Crowther specs oregon or pine so would anyone be able to provide me a scaling factor for Paulownia ?

There was possibly an expectation that I would or could reply to your question. Unfortunately I just sell Paulownia and don't have the qualifications to provide the information you need. Paulownia is not rated as a structural strength timber so if you were to use it then you would need a qualified person to make the calculations as to how much to increase the dimensions of Paulownia to achieve the same structural strength for your design. I'm sure that the increase in the sizes would still give you the strength you need and be a considerable saving in weight. The only qualified person who I know that has done extensive work on this is a naval architect Mark Bowdidge from Bundaberg Qld. He has a web site and if you felt it worthwhile you could contact him.

Whitewood,

Found necessary info on scaling for stiffness on Michael Stores site. Was hoping to hear back about Paulownia plywood.
