Subject : Timber Flex vs. bending ply

I have noticed the recommendation for using 3/8" bending ply for curved forms. I used timberflex to form the panel for a sleigh bed I am working on. It is available in various thickness's and is faced one side with poplar. Is there anything I need to be concerned about? thanks for your help.

Also, I have not been able to find the gallery mentioned above. Is it still active?

I'd certainly suggest trying a mockup to see how well it veneers. I don't know if there is any sort of coating that might affect glue adhesion, but seems unlikely. Generally it's a good practice to veneer both sides of any substrate, to equalize stresses. Are you planning to fill, sand, and veneer the kerf side as well?

I have actually already laid it up. I used 1/8" bending ply on the kerf side and veneered both sides at once to keep it balanced. It worked really well, very minimal if any springback. I have heard of the kerfs transmitting through the veneer and was wondering if anyone had any issues with that. thanks for your help.

Martin,

I think timberflex is fine until you try really tight radiuses and then you can possibly get some kerf telegraphing. If you don't mind dealing with the kerfs using these type of products are fine. I also think the attachment of kerfed panels can be more of an issue in some circumstances because of the voids the kerfs create.

I like the way you put a sheet of 1/8" in between the timberflex, much better than kerf to kerf.
