This project was an experiment to determine if two sheets of veneer could be laminated using epoxy to create a strong, flexible material for constructing thin bowls and other objects in a vacuum press. The answer is “yes”. I am indebted to Ger21 for answering my question on a suitable low viscosity epoxy. He suggested US Composites 635 resin which worked perfectly.
The thumbnail picture shows how light is transmitted through the .038” finished laminate. The light wood is ash and the dark is walnut. Pie shaped veneer was prepared in the classic manner with tape as shown in photo one. The grain of the second sheet runs 90 degrees to the first. One sheet is epoxied, lined up with the other and wrapped in wax paper to prevent sticking to the mold. The five laminates were made at once and put in the press. This epoxy takes a day to cure but you will really appreciate the open time when constructing complex pieces.
Look at the edge of the laminate in photo three. It shows the epoxy squeeze out after pressing. The epoxy penetrates the wood, veneer tape and is only stopped by the wax paper. The only way to get the veneer tape off is sanding. Sanding knocks off the plastic look and exposes the wood. This laminate is STRONG and extremely flexible!
The final photo is a scalloped platter I made which I don’t like a bit. It’s 24” in diameter and you can load it with fruit without failure of the laminate.
I plan to use this technique for pierced objects, screens and back lit panels on future projects and would appreciate any other ideas you may have for this material. Thanks for your interest.
